The Custom Fabrication product category covers OEM replacement parts and special mesh assemblies that do not fit a single catalog family — welded filter sleeves, framed panels, multilayer packs, conical screens, perforated-supported parts and wedge wire assemblies built from drawings or samples. Buyers often have a worn part, partial dimension list or PDF drawing without a clean BOM; KAIFIL reviews materials, tolerances and manufacturability before quoting. Capabilities span cutting, edging, welding, stamping, forming, assembly and export packing. Send drawing format (PDF, DWG, STEP), material grade, filtration rating if applicable, installation dimensions, working conditions and annual quantity — we confirm key missing details before quotation, with NDA available on request and lead time confirmed per project after specification lock, including separate sample and production MOQ when validation is required.
Drawing-based fabrication with DFM feedback on tolerance, material and cost before you commit to batch production.
We work from sample photos, marked-up PDFs and dimension tables — list what you know and we confirm critical gaps before quote.
NDA execution on request; drawings used only for quotation and production, not shared with third parties.
We quote finished fabricated parts and can align raw mesh supply with the same lot when validation requires — state your preference on RFQ.
Screen filter parts / cylinders / custom inserts for mixed stainless steel screen and filter part rfqs, supplied to drawing with material, size and packing details confirmed at RFQ stage.
Cut, formed and welded wire mesh parts for custom equipment screens and fabricated filter inserts, supplied to drawing with material, size and packing details confirmed at RFQ stage.
Custom components / inserts / strainers for replacement filter parts and oem stainless assemblies, supplied to drawing with material, size and packing details confirmed at RFQ stage.
Welded assemblies / framed filters / cartridges for oem filtration assemblies and replacement parts, supplied to drawing with material, size and packing details confirmed at RFQ stage.
Typical RFQs include stainless mesh cylinders, welded filter sleeves, framed mesh panels, filter discs, multilayer screen packs, strainer baskets, conical screens, perforated-metal-supported mesh parts, wedge wire assemblies and custom filter components from drawings or samples. If your part combines multiple processes, send the assembly drawing rather than only the mesh callout.
Multi-step parts (cut mesh, weld frame, insert perforated core, assemble pack) should be sent as one assembly drawing with item numbers — quoting mesh alone without frame often misses tolerance stack-up at the gasket seat.
Material grade, filtration rating or mesh specification, all installation dimensions and tolerances, weld or edge requirements, operating temperature and media, quantity and required documents (material cert, dimensional report). Photos of worn samples help when dimensions are hard to measure in service.
Weld symbols, edge prep and inspection class (visual, dye penetrant where applicable) should match your quality plan — state required documentation on RFQ so inspection time is included in lead time.
After drawing review we return material, tolerance and cost feedback — typically within one to two business days for complete packages. Samples or first-article photos are offered when weldment complexity or interface validation requires it; batch schedule follows sample approval.
Prototype or sample quantity before batch OEM release is common — we quote sample stage separately from production MOQ when validation is required. Sample approval may be photo-based or dimensional report based on your criteria.
Tolerances are quoted to your drawing where achievable; unreachable combinations are flagged in DFM. NDAs are standard for OEM programs — request execution when opening the project. Data deletion on request after project close is available.
Export packing (carton, crate, VCI, pallet pattern) can follow siteSettings defaults or your PO packing spec — note if parts are sharp or heavy and need edge guards. Marking part number and revision on each piece reduces mix-ups at your line.
PDF, DWG or STEP with material, tolerances, quantity and process notes. List missing dimensions you cannot measure. Note required inspection documents on the PO.
When only a worn sample exists, bag and ship the sample or send caliper photos with reference scale — list dimensions you cannot reach in service. We return a DFM note listing missing data before formal price.
MOQ and price depend on process steps, alloy and inspection level — confirmed per quote, not from a single site-wide number. Lead time follows material availability and process load after specification lock. For full process detail see the Custom Fabrication landing page at /custom-fabrication/.
Browse product categories for standard families; fabrication fills gaps when catalog geometry or tolerance does not fit. Full NDA and drawing workflow detail is also on the Custom Fabrication landing page at /custom-fabrication/.
Use standard product categories when a catalog family fits your duty; use this fabrication hub when tolerance, interface or multi-process assembly requires a drawing-based quote. The dedicated Custom Fabrication landing page at /custom-fabrication/ describes DFM workflow, NDA and file submission in more detail. Related categories for raw mesh, discs, cylinders and sintered media appear in the related categories section — reference them in your RFQ when the fabricated part includes purchased sub-components we should source or you will supply.
Multi-component assemblies should list which parts KAIFIL fabricates versus which you supply FOC — this avoids double-counting mesh or plate on the quote. Revision control on the drawing (rev letter and date) should match your PO; we return a DFM note listing any missing dimensions before formal price. Prototype quantity, production MOQ and export packing can be quoted as separate line items when your validation gate requires sample approval before batch release.
| Capability | Typical output | Input |
|---|---|---|
| Cutting | Discs and shapes | Drawing or OD |
| Welding | Cylinders and baskets | Joint detail |
| Stamping | Repeat parts | Tooling confirmation |
Prototype before mass production is recommended for new parts.
Yes. Request NDA execution when you open the project; we review drawings under confidentiality before quoting.
STEP, PDF or DWG with material, thickness, weld symbols and critical tolerances highlighted. Photos and marked-up sketches are fine for early feasibility.
Yes—define inspection points and documentation on the PO. We align in-process checks before batch release.
Yes—multi-component assemblies are common. Bill of materials and sequence are confirmed before production.
After drawing review and material confirmation; sampling may apply for new weldments—lead time confirmed per quote, not assumed.
Send your specification, drawing or operating conditions. We reply with a technical quote, not a form letter.
Uploaded reference files are included with the inquiry. For larger CAD packages, reply to the confirmation email or send them here:
