Laser Cutting Capability
Laser cutting is where many trolley projects begin. Deck plates, shelves, caster mounting plates, brackets, side guards, drawer panels, pegboard panels and custom cutouts must be accurate before bending, welding, coating and assembly can be stable.
Engineering Context
A trolley may look simple, but precision sheet metal fabrication decides many downstream problems. If wheel plate holes are off, casters do not align. If shelf blanks are not consistent, bending and welding fixtures become harder to control. If cut edges remain sharp, the finished trolley is less safe to handle and powder coating can look poor around corners.
DoingMetal public content lists TRUMPF laser cutting, multiple laser machines and a sheet processing range of 0.5-18 mm depending on material. For each RFQ, the practical limit should still be checked against material grade, thickness, part size, hole size, edge quality and whether the part will be bent, welded or coated after cutting.
For custom trolley buyers, laser cutting is useful when the product needs accurate holes, slots, tabs, mounting plates, logo plates, ventilation patterns, lightening cutouts or repeated parts across a production batch. It also helps prototypes move faster because no hard tooling is required for the first flat blanks.
Capability Details
| Item | What to Confirm | Why It Affects Quality |
|---|---|---|
| Equipment | TRUMPF laser cutting and multiple laser systems are listed in public DoingMetal / FuleiMetal materials. | Machine stability, programming and nesting affect cut accuracy, delivery speed and repeatability. |
| Materials | Carbon steel, stainless steel, aluminum, galvanized sheet and selected non-ferrous sheets can be reviewed by drawing. | Material type changes cutting gas, speed, burr risk, oxide layer, heat effect and finish choice. |
| Thickness | DoingMetal public content states 0.5-18 mm depending on material. Thicker or special materials should be confirmed case by case. | Thickness changes kerf, taper, burr, heat input, flatness and whether the part can be bent or welded afterward. |
| Tolerance | Public DoingMetal content mentions +/-0.1 mm precision for laser cutting; final tolerance should be agreed by drawing and inspection method. | A trolley normally has functional tolerances around holes, wheel plates and assembly interfaces rather than every cosmetic edge. |
| Design Files | DXF, DWG, STEP, PDF or dimensioned sketches. STEP plus 2D drawings are preferred for assemblies. | Clear files reduce quoting errors and avoid wrong hole sizes, missing bends or unmarked critical dimensions. |
Process Know-How
Common parts include platform decks, shelf blanks, caster plates, handle brackets, drawer fronts, side guards, cable hooks, mesh reinforcement plates, label plates, folding hinge plates and custom fixture plates. These parts often move to bending or welding after cutting, so bend reliefs, hole spacing and tab locations should be reviewed together.
Small holes, narrow slots and sharp internal corners can create heat, burr or fit-up problems. Holes near bend lines may deform during forming. Cosmetic parts handled by operators should specify deburring, corner radius or edge-break requirements. If the trolley is powder coated, tight mating holes and hinge areas may need allowance for coating build-up.
Before batch cutting, the program, material thickness and first parts should be checked. Critical hole-to-hole dimensions, outside size, slot width and visible edge condition can be measured. Parts that later become wheel plates or mounting brackets deserve special attention because they affect caster alignment and assembly speed.
Inspection
RFQ Preparation
For custom trolley projects, a clear RFQ helps us choose the right process, avoid overbuilding and identify quality risks before sample production.
Buyer FAQ
Sometimes yes for flat brackets, plates and guards. Most trolley parts still need bending, welding, deburring, coating or assembly after cutting.
Normally send the final required dimensions. The cutting program should handle kerf compensation. If your file is only a cutting path, explain that clearly.
Use tight tolerances only where function requires them, such as caster holes, mating slots and assembly interfaces. General outside edges can often use normal sheet metal tolerances to control cost.
Material type, thickness, cutting gas, speed, focus, nozzle condition and part geometry all affect edge quality. Thick plate and small holes need more careful review.
