Overview
Custom shaped metal box, fabricated and finished in our own workshops
Tooling, stamping, laser cutting, bending, welding and surface finishing all run in our eleven workshops in Foshan — the part never leaves the plant between steps.
Some housings cannot be a cuboid: a cover that follows a hand, a box that clears a motor, a casing with a tapered end. A shaped box is built from a developed flat pattern, bent on a CNC brake and closed by welding, so the form follows the product rather than the sheet stock.
The flat pattern is developed from your model, cut, then bent through the sequence that keeps the last fold accessible. Welded seams are ground and the surface is polished or brushed so the shape reads as one piece. Where a radius has to be tight, it is rolled instead of bent.
Send the shape as a STEP model, or a section drawing if the box is prismatic. We come back with the developed pattern, the fold sequence and the finish options, and flag any face that cannot be formed in one piece.
In-stock items start at one piece. Custom and OEM projects are quoted from your drawing, with the die designed and maintained in our own tool shop.

Why this drawing matters. Every tolerance, hole position and bend radius on this page is confirmed against a drawing during quotation — so what you approve is what gets inspected at the end of the line. The published drawing is a generic sample, never a customer's file.
Certifications behind the batch
- ISO 9000 — the quality management system our stamping and forming lines run under, from incoming material to final inspection.
- CCC — China Compulsory Certification, the domestic market access mark.
Paperwork that travels with the goods
- Batch inspection record — the production run's dimensional and appearance checks, reported in English.
- Material certificate — the mill certificate for the steel or aluminium heat, on request.
- Third-party inspection — SGS, TÜV, BV or your own QC are welcome at the plant before loading.
UL, CE, RoHS, ETL
Overseas marks are applied for by the importer in its own market — the normal division of labour in this trade. Our side of it: samples, material data and process records for your test house, and manufacture and inspection to the standard your drawing names (ASTM, EN, ISO). A mark goes on nothing we have not tested.
Why this part
Six things that decide whether a custom part arrives right
Every one of them sits inside our own plant, on the same floor as the parts.
26 presses + 350T drawing
160T × 2, 100T × 4, 80T × 8 and 60T × 12 presses, plus a 350T hydraulic press for deep-drawn housings and larger shells.
In stock from 1 pc
Standard items ship from stock with no minimum order. Custom and OEM runs are quoted from your drawing, with tooling built here.
Tooling made in-house
Three utility patents on our own tooling. The die is built and maintained by the same team that runs the press, so a design change moves with the part.
Documented, not decorated
ISO 9000 and CCC held. Each batch leaves with an inspection record, material certificates on request, and third-party inspection is welcome before loading.
Inspect before you pay
SGS, TÜV, BV or your own QC team can walk the line and inspect finished parts at our plant. Reports go to you, not to us.
Production process
How the order runs on our floor
Five steps, in this order, all in Foshan.
1
Drawing review
Send a PDF, DWG, DXF or STEP file. We check material, sheet thickness, tolerance and surface finish, and flag anything that needs adjusting before quoting.
2
Tooling in-house
Dies are designed, cut and maintained in our own tool shop — three utility patents on our tooling. A design change moves with the part.
3
Stamping & forming
26 presses from 60T to 160T, plus a 350T hydraulic press for deep-drawn shells. Laser cutting and CNC bending handle blanks and complex forms.
4
Welding & finishing
Tapping, welding, grinding and polishing complete the part. Surface treatment is specified to your drawing and documented per batch.
5
Inspection & shipment
Incoming checks, in-process checks and a final layout inspection. SGS, TÜV, BV or your own QC team are welcome before loading.
Factory
Made in Foshan since 2004
We run 13,000+ m² across eleven workshops in Foshan, Guangdong, China, with 51–100 staff. Sheet metal is the whole plant: the die is built where the part is stamped, the finish is applied where the part is formed, and a quality question is answered by the people who made the part.

How to order
From drawing to delivery
Four steps, no account required. We reply within one working day.
1 Send your drawing
PDF, DWG, STEP files or a physical sample all work. Tell us the quantity you have in mind — one piece is a valid starting point.
2 Engineering review
We confirm material, tolerance and surface finish, and flag anything that needs adjustment before quoting.
3 Sample first
A prototype is produced in 4-7 days so you can verify fit, finish and assembly before committing to volume.
4 Mass production
Laser cutting, CNC bending, punching, welding and in-house surface treatment are all completed under one roof for consistent quality.
OEM and ODM projects are welcome, and we can support you in meeting your target-market certification requirements. Custom shaped metal box are produced in our Foshan factory, where 26 punch presses plus CNC laser cutting and bending equipment handle both one-off prototypes and repeat production runs.
FAQ
Frequently asked questions
The questions buyers ask most before requesting a quote.
My shape has a face that cannot be bent. What then?
That face becomes a separate part, welded or fastened on. We say which faces those are at drawing review rather than discovering it at the brake.
Can you polish a welded shaped box to a mirror?
Yes, but the weld has to be dressed progressively or the polish shows a wave. It is priced by the seam length, so tell us the finish before we quote.
Do you make the flat pattern?
Yes. The development comes from your model and is sent back for confirmation before cutting, because a wrong development wastes the whole blank.
Which files do you need to quote?
PDF, DWG, DXF, STEP or a physical sample. A sketch with the overall dimensions is enough to start; we tell you what is missing before quoting.
What certificates come with the order?
We hold ISO 9000 for quality management and CCC, the China compulsory certification. Every batch ships with an inspection record, and mill certificates for the material are available on request. Marks such as UL or CE are applied for by the importer in its own market; we supply the samples, material data and process records a test house asks for.
