Overview
Portable power station enclosure, 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.
A portable power station is carried to a tailgate, a campsite or a job site, so the housing has to take knocks, keep rain off the pack and still let the inverter breathe. This is the shell around the battery pack, the inverter and the display, including the handle, the vent field and the port cut-outs.
Cold-rolled steel or aluminium is laser cut and CNC bent, welded at the corners and ground flush, so there is no sharp seam where a hand goes. Vent and fan openings are punched as a pattern rather than drilled one hole at a time, which keeps the airflow path consistent from the first unit to the last.
Tell us the pack size, connector positions and whether the unit is carried or fixed in place. From that we set wall thickness, the gasket land on the flange and the handle position. Powder coating or brushed stainless for the outside; prototypes start at five pieces.
This part runs at 5 pcs per batch, with the die designed and maintained in our own tool shop. If you need a smaller trial before committing to the run, say so in the enquiry and we will quote the two quantities side by side.

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 we hold
- ISO 9000 — quality management system, covering incoming material, in-process and final inspection.
- CCC — China Compulsory Certification, the domestic market access mark.
What ships with the goods
- Batch inspection record — dimensional and appearance report for the production run, issued in English.
- Material certificate — 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.
Overseas marks (UL, CE, RoHS, ETL)
These are applied for by the importer in its own market — that is the normal division of labour in this trade. What we do is supply the samples, material data and process records your test house asks for, and manufacture and inspect to whichever standard your drawing names (ASTM, EN, ISO). What we will not do is put a mark on a part 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.
Runs at 5 pcs
This part is produced in batches of 5 pcs. Tooling is built here, so the die stays with the part and a repeat order does not pay for it twice.
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. Portable power station enclosure 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.
Is the housing waterproof?
We build to the gasket land and joint detail on your drawing and can add a folded flange, a lap joint and a closed-cell gasket. The ingress rating itself is confirmed by testing the finished unit, so we do not print an IP number we have not had tested.
Can the vents be made to a specific pattern?
Yes. Hole size, pitch, open area and the keep-out around the fan screws are punched from a die, so every unit matches. Send the airflow requirement and we propose a pattern.
Will the paint match our brand colour?
Powder coating is matched to a RAL or Pantone reference you supply. Send the code with the order and we return a coated sample before the run.
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.
