Overview
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 screen does its job through the hole: size, pitch, open area and the thickness of the sheet decide what passes and what stays. Get the pattern right and the screen is a part; get it wrong and it is a blockage.
Holes are punched on a CNC turret press from a pattern you specify, with the burr side controlled so the screen sits flat in its frame. Large panels are run in one hit where the table allows, so the pattern does not show a join. Sieve plates are checked for flatness after punching, because a wavy plate will not seal.
Send the hole diameter, the pitch, the open area and the frame dimensions. If you only know the flow rate and the particle size, send those and we propose a pattern. Sheets can be supplied flat, rolled or cut to a frame profile.
This part runs at 10 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.

Send a drawing for a part-specific data sheet.
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.
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
Every one of them sits inside our own plant, on the same floor as the parts.
Stamping, laser cutting, CNC bending, welding, polishing and assembly all run in-house, so tolerances are held from the first blank to the final finish.
160T × 2, 100T × 4, 80T × 8 and 60T × 12 presses, plus a 350T hydraulic press for deep-drawn housings and larger shells.
This part is produced in batches of 10 pcs. Tooling is built here, so the die stays with the part and a repeat order does not pay for it twice.
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.
ISO 9000 and CCC held. Each batch leaves with an inspection record, material certificates on request, and third-party inspection is welcome before loading.
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
Five steps, in this order, all in Foshan.
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.
Dies are designed, cut and maintained in our own tool shop — three utility patents on our tooling. A design change moves with the part.

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.

Tapping, welding, grinding and polishing complete the part. Surface treatment is specified to your drawing and documented per batch.
Incoming checks, in-process checks and a final layout inspection. SGS, TÜV, BV or your own QC team are welcome before loading.
Factory
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
Four steps, no account required. We reply within one working day.
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.
We confirm material, tolerance and surface finish, and flag anything that needs adjustment before quoting.
A prototype is produced in 4-7 days so you can verify fit, finish and assembly before committing to volume.
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. Perforated metal filter screen 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.
