For overseas buyers, a low PPAP reject rate, zero line-stops and complete traceability matter as much as a competitive price.
That is why our plant couples five specialised workshops with department-dedicated Quality Control (QC) teams and a factory-wide, real-time Manufacturing Execution System (MES). Below is a transparent look at the way we manage quality at every step, every day.<\/p>\n\n\n\n

1. Raw-Material Gatekeeping \u2013 Problems Stopped Before They Start<\/p>\n\n\n\n

\u2022 All bar, wire and sheet arrive with SGS chemical & mechanical test reports and must meet AISI \/ DIN \/ JIS \/ ISO specs.
\u2022 Incoming QC applies 100 % PMI (Positive Material Identification) and dimensions; lots failing the plan are locked in a quarantine zone and red-tagged in the MES.
\u2022 Material certificates are stored digitally and linked to the work order, so you can download them in seconds.<\/p>\n\n\n\n

2. Department-Level Quality Loops<\/p>\n\n\n\n

Production Cell<\/td>Key Machines<\/td>In-Process Controls<\/td>Typical Critical Checks<\/td><\/tr>
CNC Machining<\/td>5-axis DMG MORI, Swiss lathes<\/td>First Article Inspection (FAI) on CMM, patrol checks every 30 min, SPC charts on \u00d8 & thread pitch<\/td>\u00b10.005 mm tolerances, surface roughness \u2264 Ra0.8 \u00b5m<\/td><\/tr>
Laser Cutting<\/td>Trumpf 6 kW + Bystronic 4 kW<\/td>Edge-quality endoscope, kerf width gauge, flatness jigs<\/td>Burr \u2264 0.05 mm, HAZ width \u2264 0.3 mm<\/td><\/tr>
Single-Die Cold Heading<\/td>Chun Zu & Jern Yao headers<\/td>Die-wear log, go\/no-go ring gauges every 5 000 pieces<\/td>Head-body concentricity 0.15 mm<\/td><\/tr>
Multi-Station Cold Heading<\/td>National & Boltformer<\/td>In-die load cell alarms, optical camera on final station, roll-thread pitch gauges<\/td>Hardness dispersion < 5 HRC, grain-flow alignment<\/td><\/tr>
Stamping<\/td>Komatsu & AIDA presses<\/td>Progressive-die strip monitoring, thickness micrometers<\/td>Washer OD \u00b10.10 mm, spring angle \u0394\u2264 3\u00b0<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

All patrol data are scanned into the MES with handheld RFID readers, turning every operator into a quality sensor.<\/p>\n\n\n\n

3. Optical Sorting & 100 % Final Verification<\/p>\n\n\n\n

\u2022 Eight CCD vision sorters screen up to 600 pcs\/min, rejecting scratches, cracks, head defects or thread burrs down to 0.05 mm.
\u2022 Pass lots are sealed with a laser-engraved label carrying part number, heat-lot, machine ID and operator code\u2014full back-tracing in under 30 seconds.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

4. Mechanical & Environmental Testing Lab<\/p>\n\n\n\n

Tensile & shear test (100 kN dual-column): ultimate tensile strength, yield, proof load.<\/p>\n\n\n\n

Torque-tension rigs: prevailing-torque, coefficient-of-friction, K-factor.<\/p>\n\n\n\n

Rockwell & micro-Vickers hardness testers.<\/p>\n\n\n\n

Salt-spray chambers (ASTM B117) up to 1 000 h for Zn-Ni, Geomet, Dacromet coatings.<\/p>\n\n\n\n

Metallographic microscope: grain size & decarburisation on 12.9 class bolts.
Certified reports can ship with the goods or be filed directly into your PPAP dossier.<\/p>\n\n\n\n

5. Full-Visibility Production & Inventory Control<\/p>\n\n\n\n

\u2022 The MES dashboard shows live machine status, WIP count, SPC trends and warehouse stock.
\u2022 Automatic material requirement planning (MRP) prevents shortages and flags ageing stock; QC joins the monthly cycle count to verify packaging integrity and spec labels.
\u2022 Customers receive weekly PDF snapshots or on-demand screen shares\u2014no grey zones.<\/p>\n\n\n\n

6. ISO 9001 : 2025 + SGS Partnership<\/p>\n\n\n\n

\u2022 Quality manual, process FMEAs and control plans audited twice yearly by SGS.
\u2022 Continuous Improvement (CI) board drives Kaizen events; scrap ppm has dropped 37 % in 18 months.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

7. Rapid-Response Customer Support<\/p>\n\n\n\n

\u2022 If an anomaly surfaces, our 8D task force pulls design, tooling and QC staff into a 24-h containment and root-cause call.
\u2022 Reworked or replacement parts leave within 3\u20135 working days; corrective actions are added to the control plan so the issue never repeats.<\/p>\n\n\n\n

8. Value-Added Logistics & Packaging QA<\/p>\n\n\n\n

\u2022 Automatic counting & seal-weighing eliminate short packs; high-def cameras record every carton.
\u2022 Custom packs (tray, tape-&-reel, blister, VCI, retail box) validated through ISTA drop tests before first shipment.
\u2022 In-house freight desk benchmarks air, sea and rail rates weekly; tracking events push to your inbox in real time.<\/p>\n\n\n\n

9. What This Means for You<\/p>\n\n\n\n

Predictable line performance \u2013 PPAP right the first time, and zero-defect deliveries.<\/p>\n\n\n\n

Traceability within seconds \u2013 part of our digital DNA, not an extra service.<\/p>\n\n\n\n

Lower total cost of ownership \u2013 fewer disruptions, less incoming inspection on your side.<\/p>\n\n\n\n

Faster market response \u2013 design tweaks or urgent pulls handled without compromising quality.<\/p>\n\n\n\n
