Wire Thread Insert Manufacturer & Factory
Ankolam manufactures wire thread inserts in its own Wuxi plant — wire drawing, coil winding and 100% final inspection in-house. M2–M40, five material families, exports worldwide, engineering reply in one business day.
Ankolam is a wire thread insert manufacturer with its own production base in Wuxi, China: 17+ years of specialized insert manufacturing, 128 production and machining units, and in-house wire drawing to coil winding. Buyers work directly with an engineering-led factory — dimensions, materials and traceability verified before shipment, samples before volume, delivery worldwide.
Ankolam: Wire Thread Insert Manufacturer in China
Factory Overview
The company operates two production sites totaling roughly 20,000 m² — the Wuxi base (~12,000 m²) carries insert winding and wire forming; the second site adds automatic lathe and CNC turning capacity for solid inserts and tooling components. A sales office in Shenzhen supports South-China export logistics. Find equipment detail and the process flow on the factory page.
Production Capacity and Lines
| Line | Equipment | Site | Role |
|---|---|---|---|
| Coil winding | 50 CNC insert machines | Wuxi | Wire thread insert winding |
| Wire drawing | 16 diamond-section drawing machines | Wuxi | Round wire → diamond profile (in-house) |
| Turning | 35 automatic lathes | Second site | Solid inserts, tooling parts |
| Swiss-type machining | 15 CNC Swiss-type lathes | Second site | Precision components |
| CNC turning | 12 CNC lathes | Second site | Custom & OEM dimensions |
In-house wire drawing is the quiet quality advantage: the diamond profile determines thread accuracy, and drawing it ourselves removes the largest outside-variable in insert quality. Semi-finished stock on standard sizes shortens routine delivery by about half.
Manufacturing Capabilities
Cold Rolling and Wire Forming
Round wire enters; diamond-section wire leaves — rolled under process standards at every step. The four-step production chain is fixed and auditable: incoming material inspection (spectrometer chemistry check) → wire drawing → coil winding → final testing (tensile, mechanical properties, surface).
Size Range M2 to M40
| Dimension | Range |
|---|---|
| Metric coarse | M2 – M40 |
| Metric fine | M7×1 – M39×3 |
| Inch (UNC/UNF) | 2-56 – 7/8-9 |
| Lengths | 0.5D – 3.5D (common 1D/1.5D/2D/2.5D) |
| Tanged / tangless | Both, from the same lines |
Fine Pitch and Custom Profiles
Fine pitch, non-catalog lengths, special materials and customer-specific geometry are quoted from drawing — the CNC and Swiss-type lines exist exactly for these. Standard responses include a dimensional proposal before pricing.
Quality Control from Our Factory
Quality Management System Scope
Production runs under an AS9100D-compliant quality management system (additional-site scope) — aerospace-grade process discipline applied to every order: first article inspection on new part numbers, full lot traceability with material heat numbers, and process controls aligned to the standard. Documentation packages are available for supplier qualification audits.
Dimensional Inspection Equipment
| Equipment | Use |
|---|---|
| Handheld spectrometer (German-made) | Incoming wire chemistry verification |
| Optical measuring system (300×200 mm, 2.8 μm/100 mm) | Dimensional inspection of finished inserts |
| Tensile tester | Mechanical properties per lot |
| Rockwell hardness tester (HRA/HRB/HRC) | Hardness verification |
| Salt-spray cabinet (neutral / acetic) | Coating & corrosion checks |
| Universal tool microscope | Thread profile & pitch measurement |
Full-Size Sampling and Mill Test Certificates
Finished inserts receive 100% dimensional inspection before release — not statistical sampling — and every lot retains heat-number and batch documentation. Mill Test Certificates ship on request; see quality control for the full process narrative.
Product Range from Our Factory
Free-Running and Screw-Locking Inserts
Both functional types across the full size range — see wire thread inserts for the technical hub, including tangless variants and the material selection tables (304H, 316, Nitronic 60, Inconel X-750, phosphor bronze, titanium).
Export Supply Experience
Ankolam serves global B2B buyers across time zones with 7×24 responsiveness — aerospace, gas turbine, semiconductor and data center programs among them (see case studies). Export documentation is handled in-house; supplier qualification reviews by leading industrial enterprises have been passed (aerospace-adjacent, rail, new-energy vehicle and electronics customers).
17+ Years · 128 Machines · 20,000 m²
Founded-team experience of ≈20 years in aerospace engineering, quality and certification. Growth from an RMB 10M+ revenue base to RMB 80M+ with two production sites. New Wuxi plant investment commissioned in 2021 — capacity headroom for volume programs.
Manufacturer FAQ
Can we audit the factory before ordering?
Yes — factory visits and supplier audits at the Wuxi plant are welcome by appointment; third-party inspection agencies are received on-site. Arrange through the contact page.
Do you manufacture everything or trade parts of the range?
Wire drawing, coil winding and solid-insert machining are in-house (the equipment table above is our own plant). Where a project needs processes outside our lines, we say so explicitly at quotation — no silent outsourcing.
What is the MOQ for factory-direct supply?
Standard catalog sizes support low MOQs from semi-finished stock; custom dimensions and materials are quoted per project. Send the requirement — samples precede volume orders.
How fast is the engineering response?
Within one business day, worldwide. Drawings can be attached to the RFQ form or emailed directly.
