CHENDA · Manufacturing applications
Sheet metal fabrication converts flat stock into finished components through a connected sequence of cutting, edge preparation, bending, joining and inspection. The best equipment plan starts with the complete route. A faster laser will not solve a bend collision, a variable weld gap or a deburring bottleneck.
CHENDA can discuss sheet metal laser cutting, press brakes, deburring and finishing, welding systems, cleaning and marking as one production chain. The correct combination depends on the part family and its handoffs.
01 / Start with the workpiece
The route applies to panels, brackets, bases, guards, electrical enclosures, cabinets, machine covers, frames, ducts, shelves and welded assemblies. Common metals include carbon steel, stainless steel, galvanized sheet and aluminum, but grade, coating, flatness and surface protection can change the process.
Record the minimum, normal and maximum thickness. Also identify material that represents most production. Selecting every machine around a rare maximum can increase capital cost and reduce efficiency on normal work.
Important part features include:
02 / A connected production route
Confirm units, bend deductions, revision and material before nesting. Separate geometry that belongs to the flat pattern from features created later. Use part identification when similar shapes or revisions could be mixed after cutting.
The laser creates the flat blank and most programmable internal features. Machine selection should address sheet format, thickness, material, part mix, edge requirement, assist gas, extraction and handling. The CHENDA source range includes open single-table directions, open exchange tables, enclosed exchange tables, precision formats, large-format beds, sheet automation and coil-fed lines.
An open machine gives direct access and can suit varied workshop loading. An enclosed machine can improve separation of the laser process and support controlled extraction, subject to the final safety design. Exchange tables reduce non-cutting time when the loading and unloading rhythm can keep pace. Automation is most valuable when sheet sizes, stacks, schedules and downstream sorting are sufficiently controlled.
For repeated parts from thin coil, an uncoiling, leveling and cutting line may reduce manual sheet handling. The material range, coil mass, flatness, stress release and unloading method must be validated. Coil processing should not be chosen only because production volume is high.
Laser-cut parts may carry burr, dross, sharp edges or oxide that affects handling, coating or welding. Define the defect and outgoing requirement. Light burr removal, uniform edge rounding, heavy slag removal and surface finishing use different stations and abrasives. Small-part retention, protective film and visible grain are critical selection inputs.
The press brake forms the flat blank. Required force is calculated from material, bend length, tooling and method. The machine must also provide enough working length, stroke, daylight and throat for the part and sequence. Backgauge axes position the blank, while crowning or compensation helps manage deflection on applicable machines.
Choose among torsion-bar, electro-hydraulic CNC and electric press-brake directions based on the work, accuracy, programmability, energy and maintenance priorities. The finished drawing and bend simulation provide a stronger basis than tonnage alone.
Tabs, slots, consistent bends and fixtures reduce weld variation. Handheld laser welding can suit flexible work when the process and safety controls are appropriate. Automatic or robotic welding becomes more relevant when the seam, part datum and fixture repeat. MIG/MAG and laser welding remain separate choices with different gap tolerance, penetration, wire, gas, heat input and safety requirements.
Laser cleaning may remove selected oxide, coating or residue before or after another operation, subject to sample validation. Laser marking can add part numbers, assembly references or traceability information on compatible surfaces. Confirm whether later bending, welding, cleaning or coating will damage or obscure the mark.
Final inspection should follow the drawing and function. It may cover blank dimensions, hole location, bend angle and flange, fit-up, weld condition, edge safety, surface appearance and assembly.
03 / Match the format to production
| Production condition | Direction to evaluate | Questions to resolve |
|---|---|---|
| Mixed jobs with manual loading | Open sheet laser | How will sheets and parts be handled safely without damaging surfaces? |
| Repeated work with loading during cutting | Exchange-table laser | Can operators or automation clear one table before the next exchange? |
| Need for enclosed process area | Enclosed exchange-table laser | What enclosure, extraction, monitoring and access functions are included? |
| Long or oversized plate | Ground-rail or large-format laser | How will plate be stored, loaded, supported, nested and unloaded? |
| Repeated thin material from coil | Coil-fed laser line | Does leveling produce the required flatness and how are finished parts removed? |
| Sheet and occasional tube work | Sheet-and-tube combination machine | Is the production split high enough to justify a dedicated machine instead? |
Use sheet-and-tube equipment only after comparing its tube range, sheet workflow and changeover with the actual workload.

05 / Evaluate representative parts
Select acceptance parts that expose the real risks. A useful laser sample may combine outside contours, small holes, internal corners, dense pierces and a surface that reveals scratching. A press-brake sample should include the longest critical bend, short flanges or a sequence with collision risk. A welded sample should use the intended joint, fit-up and fixture.
Record the material, drawing revision, machine configuration, gas, tooling, abrasives, parameters and inspection method. Measure more than one part when repeatability matters. Note the time spent loading, programming, sorting and reworking, not only active cutting or bending time.
06 / Look upstream
A connected process review usually finds more improvement than replacing one machine in isolation.
07 / Application questions
It depends on the incoming edge and downstream requirement. If manual grinding is a bottleneck, edges must be touch-safe, coating adhesion is sensitive or consistent rounding is required, evaluate a finishing process with actual parts.
It can reduce footprint and initial duplication, but it also combines workloads and may constrain tube capacity or scheduling. Compare production hours, sizes and changeovers with separate machines.
Automation can reduce repeated handling when material, schedules and interfaces are stable. It also adds storage, controls, recovery procedures and downstream sorting. Review the whole line and the personnel still required.
Confirm the ordered configuration, machine functions and a representative part. State dimensions or quality features, material, tooling, measurement method, records and unresolved-item process before testing begins.
Your material. Your part. Your production route.
