OEM capability depends on controlled process ownership and clear inspection evidence. Operating from Shenzhen and Dongguan, we coordinate precision machining, heat treatment, and inspection routes for global procurement programs.
CNC turning and thread-grinding routes are selected around lead accuracy, surface roughness, runout, and inspection evidence. This is critical for controlling motion quality in compact medical, robotics, and aerospace mechanisms.
Heat-treatment routes for 100Cr6, GCr15, 440C, stainless, or customer-specified steels are locked with hardness, case-depth, and surface-finish checks where the application requires them.
Quality records are planned to reduce supplier-qualification risk for compliance-driven buyers. We align inspection packages to customer flowdowns, ISO 9001-style audit expectations, medical QMS records, aerospace documentation, and program-specific release criteria.
| Test Type | Equipment | Standards / Reports |
|---|---|---|
| Material Traceability | Spectrometer | EN 10204 3.1 Material Certificate (MTC) |
| Micro-structure & Hardness | Vickers / Rockwell Testers | Case depth and surface hardness validation |
| Dimensional Accuracy | Coordinate Measuring Machine (CMM) | Micron-level geometric tolerance reports |
| Non-Destructive Testing | Magnetic Particle Inspection | Surface crack screening report where required |
Standard commercial orders can use ISO 2859-1 / AQL sampling, while higher-risk programs can define first-article or expanded inspection before quotation. From preload torque curves to lead accuracy charting, the required data package is agreed alongside the hardware scope.
Procurement and quality teams can request different evidence levels by application risk. We align the inspection package before sample release so commercial quote, engineering validation, and supplier qualification use the same acceptance basis.
| Program Type | Typical Records | Decision Use |
|---|---|---|
| Humanoid robot pilot builds | First-article dimensions, preload torque, axial play, hardness, and lead accuracy trace. | Compare actuator samples and stabilize repeat-lot acceptance before scaling. |
| Medical or lab automation | Material traceability, surface finish, lubricant notes, cleanliness or packaging plan, and backlash report. | Support design-history and validation records without rebuilding samples later. |
| Aerospace mechanisms | EN 10204 3.1 MTC, heat-treatment lot, CMM report, hardness report, and customer flowdown checklist. | Give supplier quality and engineering teams a qualification package early in the RFQ process. |
We welcome OEM procurement teams to conduct rigorous supplier qualifications. Whether you require a physical plant tour or a virtual live-streamed audit of our CNC and CMM facilities, our engineering and QA teams are ready to provide full transparency.
