Quality control
If it can be measured, it is measured — twice
A promise line proves nothing; a measured file does. Here is the five-gate process every part passes before it can be quoted to you.
- 1
Supplier audit
Factories are audited on tooling, heat-treatment control and batch traceability before any purchase order. We keep approved-vendor lists per part family.
- 2
Incoming inspection
Every inbound batch is sampled against AQL 2.5. Dimensions are checked on the CMM or with calibrated gauges against the OEM drawing.
- 3
Material verification
Undercarriage parts: hardness depth on pins, bushings and rollers; HRC profile recorded per batch. Castings get UT spot checks for slag.
- 4
Functional bench tests
Pumps and motors run on the flow/pressure bench to the OEM curve. Injectors are pattern-tested. Each unit ships with its own test sheet.
- 5
Pre-shipment report
Photos, measurement records and test results are compiled into the shipment file — you approve before the container seals.
Test coverage by category
| Category | Standard tests |
|---|---|
| Undercarriage | Pitch elongation, hardness depth, seal pull test, proof load on link groups |
| Hydraulic | Flow & pressure curve, case-drain leakage, burst test on cylinders (sampled) |
| Engine | Injector pattern report, turbo balance certificate, gasket material certs |
| Electrical | Continuity fixture test, connector IP check, ECU load-run |
| Filters | Media weight & pleat count, burst pressure, collapse ΔP, anti-drain valve check |
| Seal Kits | Material durometer, FKM identification test, dimension spot check |
Third-party inspection (SGS / BV) is available on request for container orders, at cost. Test reports shown on this website are illustrative samples — your order always ships with reports for your actual batch numbers.
