Factory Updates

Today's photos: a 130 T / 4000 mm press brake wrapped in stretch film and lashed to a flatbed trailer, rolling out of our loading bay on its way to the port. This is the most popular mid-size configuration we build — large enough for a serious fabrication shop, still small enough to ship in one piece without splitting the machine apart.

1. What 130T/4000 Actually Covers

130 tonnes — about 1275 kN — spread across a 4000 mm bed. Used along the whole length, that is roughly 4–5 mm mild steel; concentrate the same force on a shorter piece near the centre and the machine handles 8–10 mm. In practice this size serves ventilation ducting, panel and facade work, electrical enclosures, chassis frames and agricultural parts — the middle band of fabrication that neither a bench brake nor a 250-tonne machine covers well.

2. How a Four-Metre Press Brake Gets Packed

A machine that ships in one piece arrives in one piece — every bolt we loosen at the factory is a bolt somebody has to refit, and a datum we hand over to the customer to find again.

• Loaded as a single unit — the frame, ram and bed travel assembled, sitting on a timber base that spreads the weight across the trailer deck;
• Stretch film, not a wooden crate — several layers of wrap hold dust and moisture out and let the machine be lifted and re-lashed at the port without unpacking;
• Lashed, not parked — steel straps from the machine's own lifting lugs down to the trailer's twist-locks take the road shocks of the trip to the terminal;
• Control pendant protected separately — the screen and its arm are the most fragile parts of any press brake, so they are wrapped and padded on their own, as you can see at the right of the second photo;
• Loose parts boxed — tooling segments, foot switch, manuals and spare seals travel in a separate marked crate bolted to the same deck.

3. Why Buyers Choose This Size

• Two independent cylinders, Y1 and Y2 — the labels on the side housings give away the layout: the CNC reads both cylinders and corrects the ram tilt continuously, so parallelism does not depend on the operator;
• Still one truck, still one container slot area — a 4 m brake needs flat-rack or trailer space, not a special heavy-haul permit the way a 5 or 6 m machine does;
• Room to grow — shops that start at 100 T tend to fill this machine within two years; buying 130 T now avoids the awkward second purchase;
• Tooling is standard — 4000 mm machines use common American-European style tooling, so replacement dies are available locally instead of only from us.

Today's photos: small-tonnage CNC press brakes coming off the final assembly line, destined for Vietnam, Thailand and the wider Southeast Asian market. These are the 30–60 tonne class on 1100–1600 mm beds — the size that sells best into workshops that are moving from outsourced bending to bending in-house.

1. Why Small Tonnage Dominates This Market

Southeast Asian fabricators mostly work thin: 0.5 to 4 mm mild steel and aluminium for ductwork, signage, kitchen equipment, electrical enclosures and brackets. A machine sized for that range costs a fraction of a 130 T brake, fits through a normal workshop door, runs on ordinary shop power, and — the part owners care about — pays for itself in months rather than years. Small does not mean simple: the control in the first photo is the same class of touchscreen we fit to our largest machines.

2. How to Size a Small Press Brake Correctly

Size the machine by the longest bend and the thickest plate you actually buy — not by the biggest job you hope for.

• Tonnage — up to 4 mm mild steel, 30–40 T is comfortable; 5–6 mm needs 50–60 T; beyond that, move up a class rather than run the press at its limit;
• V-die opening — the working rule is die opening ≈ 8 × material thickness; too narrow creases the plate, too wide multiplies springback;
• Bed length — measure the longest sheet you fold, not the longest you cut; a 1500 mm machine with 1250 mm tooling covers most enclosure work;
• Angle readout — the screen above shows the bending angle (98.60°) and the finished outside dimension (98.50 mm) side by side, so the operator corrects the part in front of him, not the drawing on the wall;
• Manual handwheel — the big dial under the screen is not a retro detail: it lets one person jog the ram and set the die by hand during tool changes.

3. What to Spend On and What to Skip

• Worth every dollar — quick clamps — the red-handled clamps in the second photo cut a tool change from twenty minutes to two, which matters most on short-run job work;
• Worth it — motorised rear gauge — once you run repeat batches, a powered X axis removes the manual measuring step entirely;
• Optional — segmented upper tooling — short pieces and boxes with closed sides need a punch you can shorten, as shown here;
• Skip it on a small machine — hydraulic crowning — under about 1600 mm the frame deflection is small enough that mechanical cam compensation does the job for less money.

Today's photo: a brand-new model press brake standing in the workshop with its full enclosure fitted — the machine is being finished before it goes up on the product page. White sheet-steel guarding wraps the frame, tinted polycarbonate windows keep the bend line visible, and hinged doors give service access without removing a single panel.

1. Why Enclose the Whole Machine

On a press brake the danger zone is not only the ram — it is the entire working envelope between the upper and lower tool, plus the rear gauge travel behind it. A guard fence at the front stops a hand; an enclosure stops a hand, a sleeve, a dropped off-cut and a curious walk-by. For shops that run more than one shift with rotating operators, that difference is the whole point.

2. How to Judge Safety Guarding From a Photo Like This

Good guarding answers three questions at once: can you see the bend line, can you reach the tooling safely, and does the machine stop the moment you do?

• Tinted viewing windows — the blue polycarbonate panels let the operator follow the bend continuously without leaning into the working area;
• Hinged, latched doors — the doors on the side of the hood open the whole tooling zone for setup, so guarding is never "removed for the day" and left off;
• Ventilation slots — the rows of perforations at the top and bottom of the hood draw heat out of the drive cabinet instead of trapping it around the electronics;
• Control outside the envelope — the CNC pendant on its articulated arm stands outside the hood, so programming and command happen from a position away from the ram;
• Machine still accessible — the enclosure is bolted to the frame, not to the floor: it travels with the machine and comes off with hand tools when a component needs service.

3. What Full Guarding Brings to Your Shop

• Fewer stopping incidents — the most common press brake injury is a hand under a descending ram; physical enclosure removes that path rather than relying on attention;
• Easier customer and safety audits — buyers who host factory inspections, and insurers who visit yours, read an enclosed machine as a managed risk;
• Cleaner workshop — the hood keeps scale, oil mist and off-cut fragments inside the machine footprint;
• Options that fit the frame — light curtains, two-hand control, a powered hold-down and interlocked doors can all be added to this model, so you choose the level of protection your market asks for, not the one we decided for you.

Today's photos: the ES-6020 all-electric press brake that lives in our showroom — the very machine we use for livestream demonstrations. Because it runs on servo-electric drives instead of hydraulics, it stays on the showroom floor full-time: no oil leaks, no pump noise, no smell. Customers who visit the factory or join our live stream see the same machine that ships to their workshop.

1. Why an Electric Press Brake Belongs in a Showroom

Hydraulic press brakes need a power unit, hydraulic oil and regular maintenance — they belong on the shop floor, not next to a camera. An all-electric press brake runs on servo motors that drive the ram directly through a ball-screw or belt mechanism. The result is a machine that is quiet enough to film beside, clean enough to keep in a showroom, and precise enough to bend production parts. That is exactly why this ES-6020 doubles as our livestream star and a customer-ready demo unit.

2. How to Tell an Electric Press Brake From a Hydraulic One in Photos

An electric press brake has no oil tank, no pump unit and no hoses — just servo motors on the columns and a ball-screw or belt drive moving the ram.

• No hydraulic power unit — the white side housings you see contain electric servo drives, not oil reservoirs;
• Y1/Y2 independent servo columns — each side of the ram is driven by its own servo motor for crowning-free parallelism;
• Linear-guide backgauge — the close-up above shows hardened rails, servo carriages and a chain drive that position the rear stopper with sub-millimetre repeatability;
• Clean white-and-red finish — without oil mist or hydraulic leaks, the paint stays showroom-fresh for years.

3. Benefits for Buyers Who Choose Electric

• Energy savings — servo drives consume power only during the bend stroke, cutting electricity use by 50–70 % compared with a hydraulic pump that runs continuously;
• Low noise — typical operating noise is 65–70 dB, roughly half of a hydraulic unit, so the machine can sit close to other workstations;
• Oil-free operation — no hydraulic fluid to replace, filter or dispose of, which matters for clean-room and food-packaging shops;
• Fast cycle time — electric ram acceleration is near-instant, giving shorter cycle times on thin-gauge work.

Today's photos: a row of press brake frames fresh out of the paint booth — a batch of 50T/1600 compact frames produced in volume and now waiting for export shipment. Every one of them went through whole-machine tempering (stress-relief annealing) before a single coat of paint was applied.

1. Why We Temper the Whole Frame Before Painting

Welding locks internal stress into a steel frame; if that stress stays, the frame slowly deforms and the ram loses parallelism. That is why every ZTGAOKE machine — not just selected weldments — is tempered as a complete frame to release welding stress, then milled and only afterwards painted. The result is a frame whose hardness and rigidity are proven before it ever reaches the paint line, not hidden behind it.

2. How to Judge Frame Quality From Photos Like These

Paint decides how a frame looks; tempering decides how long it stays straight — we remove the stress before we apply the colour.

• Whole-machine tempering, not spot treatment — the complete welded frame is annealed in one cycle, so no zone keeps hidden stress;
• Thick plate side housings — the upright walls you see here are cut from heavy plate and machined after tempering, keeping the ram guideways true;
• Uniform industrial coating — an even matte-grey finish seals the steel against rust during long sea freight;
• Batch consistency — a whole row of identical frames shows standardized jigs and repeatable quality, not one-off fabrication.

3. What This Batch Means for Buyers

• 50T/1600 in volume production — this compact size is built in batches, so lead times stay short;
• Export-ready — the batch is scheduled for overseas shipment, packed to export standard;
• Rigidity that holds accuracy — a tempered frame keeps bend angles stable year after year, which is what really protects your parts quality.

Today's photos: a batch of 50-ton, 1600 mm CNC press brakes built around the domestic DAC66T controller — the machine we recommend most often to price-sensitive markets. Both the whole frame and the matching tooling are stress-relieved by tempering, and the batch is priced at USD 18,888.

1. Why a Domestic DAC66T System Keeps the Price Honest

The DAC66T is a mature domestic CNC system widely used on torsion-bar and compact hydraulic press brakes. It handles 2D graphic programming, bend-angle correction and back-gauge control without the premium of an imported controller. For shops that bend standard parts it delivers the same daily usability at a fraction of the cost — which is exactly how this 50T/1600 lands at USD 18,888.

2. How a Budget Machine Stays Accurate: Tempering

A press brake only stays as straight as the stress left inside it — tempering is what we remove before we promise accuracy.

• Whole-machine tempering — welding stress is released before final milling, so the ram stays parallel year after year;
• Tempered tooling — the supplied punches and dies resist deformation under repeated load, holding the bend angle;
• Linear-guide back gauge — the rear stopper rides on hardened linear rails with precision carriages for repeatable positioning (see the close-up above).

3. Who This Machine Is For

• Budget-conscious workshops — full CNC capability without imported-controller pricing;
• Standard-part bending — enclosures, brackets, panels and light-gauge work up to 50 T over 1600 mm;
• First-time buyers — a proven, easy-to-learn platform with tempered rigidity built in from day one.

Today's photos: a 130-ton, 4000 mm electro-hydraulic CNC press brake loaded on a flatbed truck — wrapped in export-grade film, then covered with a waterproof tarpaulin and rope net for the road. The model plate on the beam reads 130T-4000, and inside the electrical cabinet sits the brain this customer specifically asked for: an imported DELEM DA-53T CNC controller from the Netherlands.

1. What Is on the Truck

• The machine — 130 tons of bending force over a 4,000 mm bed: the classic mid-range workhorse for fabrication shops, electrical enclosures, containers and structural parts;
• Synchronization — electro-hydraulic servo valves with closed-loop Y1/Y2 control, holding bend angle repeatability shift after shift;
• Export packing — anti-rust film on all painted and machined surfaces, waterproof tarpaulin plus rope net over the whole load: the machine arrives exactly as it left our workshop.

2. Why DELEM DA-53T: The Brain Matters as Much as the Body

Two machines built from identical steel can bend very differently — the difference is the controller.

• The global standard — DELEM (Netherlands) is the de-facto reference for press brake CNCs; operators in most countries already know it, so training takes days, not months;
• Graphical touch programming — the DA-53T's 10.1" high-resolution touchscreen lets you program a part by drawing its profile; the controller calculates the bend sequence, developed length and axis positions automatically;
• Full axis control — Y1/Y2 cylinders, X and R back-gauge axes plus CNC crowning in one closed loop: stable angles from the first bend to the thousandth;
• Libraries that remember — tool, material and product libraries store proven jobs, so a part repeated six months later bends exactly the same way;
• Service for the long run — worldwide service network and long-term spare-part availability, which is what a machine expected to run 10–20 years really needs.

3. Your Machine, Your Controller: We Build to Your Choice

• DELEM DA-52S — cost-effective entry level for simple flanges and boxes;
• DELEM DA-53T — the export favourite and the unit in today's photos: the best balance of price, speed and capability for daily job changes;
• DELEM DA-58T / DA-66T — more axes and 3D graphical simulation for complex multi-bend parts and offline programming;
• ESA and Estun — also available on request for customers who standardize on these brands.

Tell us your parts and your budget and we will recommend the controller that pays for itself fastest — or tell us the brand your operators already use, and we will build the machine around it.

Today's photo: a 600-ton, 5000 mm heavy-duty CNC press brake in assembly — massive red upper beam, reinforced frame and full-length safety guards. "600T/5000" means 600 tons of bending force over a 5-meter bed. A machine like this is a completely different engineering story from a small 40T/1600 unit. Here is what actually changes.

1. What Changes Structurally

• Frame and weight — a 600T machine carries dozens of tons of steel; the frame is welded from much thicker plates and fully annealed to keep flatness under extreme load. Small machines rely on lighter frames because the forces are modest;
• Drive system — large machines use bigger hydraulic cylinders (often Y1/Y2 with CNC crowning) to keep the bend line straight across 5 m; small machines can stay simple with a torsion-bar linkage;
• Tooling — the upper punch and lower die are far larger and heavier, usually segmented so two operators can still handle them;
• Foundation and handling — a 600T/5000 needs a proper concrete foundation, overhead crane support and often two operators; a small brake just needs a flat floor and one person.

2. What Changes in Capability

Rule of thumb: required tonnage grows with the square of thickness and linearly with length — double the length, double the force; double the thickness, quadruple the force.

• Small machines (40–160T, up to ~3.2 m) — ideal for thin sheet: enclosures, panels, ducts, kitchen equipment, electrical cabinets. Fast cycles, low energy use, one operator;
• Heavy machines (300–1000T+, 4–12 m) — the only choice for thick plate and long parts: structural steel, shipbuilding sections, poles and masts, pressure-vessel shells, truck frames. A 600T/5000 can bend plate that a small machine simply cannot move;
• Precision is not about size — with CNC crowning and a multi-axis back gauge, a large machine can hold the same ±0.1 mm angle repeatability as a small one. Size limits capacity, not accuracy.

3. How to Choose the Right Size

1. List your thickest material and longest part — these two numbers decide tonnage and bed length;
2. Add a margin — if your heaviest job needs 450 tons, buy 600 tons: the machine runs unstressed and lasts decades;
3. Check your workshop — door width, floor strength and crane capacity for heavy machines;
4. Two machines often beat one — many customers run a small fast brake for thin parts plus a heavy brake for thick ones: total output is higher than forcing everything through one machine.

Not sure which tonnage and length you need? Send us your material thickness, part length and drawings — our engineers will calculate the right machine and quote within 24 hours.

Today we show you a non-standard (custom-built) CNC press brake — 100 tons, 2800 mm bending length, freshly assembled in our workshop: red-and-white body, Y1/Y2 dual hydraulic cylinders, quick tool clamps and a touchscreen CNC controller. It is not a stock model from a catalog — it was designed and built to one specific customer's production requirements.

1. What Is a "Non-Standard" Machine?

A standard machine is built to fixed catalog specifications. A non-standard machine is built around your workpiece: tonnage, bending length, frame height, stroke, tooling and control system are all configured for what you actually bend every day. For this customer, 100 tons over 2800 mm with a customized working height and control setup was exactly right for their parts — something no off-the-shelf model could offer.

2. What Can Be Customized on a Press Brake

• Tonnage and bending length — from small 40T units to heavy-duty tandem lines;
• Daylight and ram stroke — heightened frame for tall-flange and deep-box parts;
• Working height and table design — matched to your operators and material flow;
• Back gauge axes — X, R, Z and additional fingers for complex multi-bend parts;
• CNC controller — the brand and language you prefer;
• Electrical system — 380V/50Hz, 220V/60Hz or any local standard in your country;
• Color and branding — some customers even order machines in their own company colors.

Rule of thumb: if your parts, your workshop or your power supply is special, your machine should be custom-built too.

3. How Our Customization Process Works

1. Send drawings or part dimensions — photos of your products work too;
2. Engineer-to-engineer confirmation — our engineers calculate tonnage, tooling and configuration, then send you a full technical proposal;
3. Production in our own factory — machining, welding and assembly all in-house, as you saw in our last update;
4. Video inspection before shipping — we bend your sample parts on camera so you can approve the machine before it leaves the factory.

Have parts that standard machines cannot handle? Send us your drawings or specifications — our engineers will design the right machine and quote within 24 hours.

Today's photos come straight from our own workshop: drilling and machining of structural parts, and frame welding by our own welders. Every ZTGAOKE machine — cutting, machining, welding, stress-relief annealing, assembly and testing — is completed 100% in our own factory. We are the manufacturer, not a trading company, and no part of the work is handed to third-party workshops.

1. Why "In-House Manufacturing" Matters

Many sellers online are trading companies: they take your deposit and then buy the machine from some factory — sometimes a good one, sometimes the cheapest one they can find. You have no way to know which. A real manufacturer like us controls everything: the steel plates we buy, the tolerances we machine to, and the welds our own people make. That is the only way to guarantee that the machine you receive performs exactly as promised.

2. How to Tell a Real Manufacturer from a Trading Company

Ask these four questions before you pay any deposit:

1. "Can you show me your machining workshop right now, on a live video call?" — A real factory can show working machines and fresh chips on the floor at any moment. A trader will make excuses or send edited videos.
2. "What machining equipment do you have?" — A manufacturer can list boring and milling machines, drilling machines, welding stations, annealing furnaces and assembly lines without hesitation.
3. "Can you modify the machine for my workpiece?" — heightened frame, larger daylight, special voltage, custom color: only the factory that builds the machine can truly customize it.
4. "What is your lead time, and who makes the spare parts?" — A factory gives a realistic schedule and supplies spare parts machined on the same equipment.

Quick rule: if the seller cannot show you live machining and welding in their own workshop at any time you ask, you are probably not talking to the factory.

3. What You Get When You Buy from the Actual Factory

1. Direct quality control — every process, from raw steel plate to finished machine, is inspected by our own team;
2. Factory-direct price — no trading-company markup in between;
3. Real customization — heightened frames, enlarged daylight, special tooling and electrical standards for your country;
4. Faster delivery and spare parts — parts are machined in-house, so replacements ship quickly even years later;
5. After-sales from the people who built it — our engineers know every machine we ship.

Today's update: a heightened CNC press brake in production — grey-black body with a red heightened structure, featuring an enlarged daylight and longer ram stroke for tall-flange workpieces.

1. Why Does a Press Brake Need to Be Heightened?

A standard CNC press brake typically offers an open height (daylight — the working space between the upper and lower tools) of around 300–450 mm, which is enough for most common bending jobs. Problems appear when the workpiece has tall flanges or deep box sections — for example tall cabinet panels, deep U-channels, door frames or large covers. During positioning or turning, the tall bent flange collides with the ram or the top beam, so the part simply cannot be placed or bent.

A heightened press brake solves this with a taller frame, longer ram stroke and enlarged daylight, reserving generous vertical clearance so tall-flange parts can be bent in one setup.

2. How to Tell Whether Your Workpiece Needs a Heightened Machine

The rule of thumb:

Required daylight ≥ Height of the tallest flange + Lower die height + Upper punch height + Safety margin (50–100 mm recommended)

Choose a heightened model if any of the following applies:

1. Tall bent flanges — the finished upright flange is taller than the daylight of a standard machine;
2. The part must be lifted or turned over the tooling — especially box-type and deep-cavity parts, which have to be raised above the punch to bend the next side;
3. The product itself is deep or tall — door frames, elevator decoration panels, cabinet side panels, hoppers, large covers;
4. Multi-bend parts — every additional bend and turnover increases interference risk; extra height is the safer choice.

💡 Not sure whether your part will collide? Send us the drawing or dimensions — our engineers will calculate the required daylight and recommend the right machine, free of charge.

3. Benefits of a Heightened Press Brake

1. Tall and deep parts finished in one setup — no outsourcing, no second clamping;
2. Easier positioning and turning — generous working space lowers the risk of collisions and scratches, protecting surface quality;
3. More orders accepted — take the deep-box and tall-cabinet jobs that standard machines cannot handle and grow your business;
4. One machine, dual duty — a heightened model bends standard parts just as well, large or small;
5. Higher efficiency and yield — less rework and trial bending caused by interference.
