Quality Control Process

The quality part consists of three processes: incoming inspection, in-process inspection and warehousing & delivery inspection.

01.Incoming Inspection

In order to ensure that the raw materials meet the requirements, in addition to the routine inspection of material brand, heat treatment and standards, the hardness, chemical composition and mechanical properties of the raw materials will also be inspected or sent to a third party for testing.Prevent fake and shoddy raw materials and standard parts, and conduct traceability inspection on material certificates or COC and physical objects based on lot number / batch number; Ensure the integrity of all chains of material manufacturers, distributors and agents.In order to meet the environmental protection requirements, the supplier shall provide relevant COC certificates. Meanwhile, we regularly sends the third party for RoHS and reach tests. In order to avoid mixing, color identification shall be carried out on the side of raw materials in the warehouse to achieve visual management.

2.In-Process Inspection

CNC Machining Part

In order to meet the measurement accuracy, 2 sets of Nano CMM are equipped with a minimum measurement accuracy of 0.001mm.

In order to meet the measurement needs of large-size parts, 1 sets of Hexagon CMM are equipped ranging of 1200x900x800 mm.

In order to meet the measurement needs of small-size parts, 5 sets of Rational Optical Imager are equipped. Measuring range: 300x200x150 mm.

In order to improve the inspection efficiency, 2 sets of TESA Digital Altimeter are equipped with a measurement range of 0-700mm.

In order to meet the inspection requirements of tooth holes, VTG brand and other brands of American and metric screw plug gauges, ring gauges and STI gauges are equipped.

In order to meet the inspection requirements of fine holes, various pin gauges are equipped.

There are also Mitutoyo Roughness Meter, caliper, micrometer, height gauge, dialgage and dial indicator.

3.Warehousing & Delivery Inspection

In order to ensure the parts fully meet the requirements, a certain number of parts are sampled for 100% full dimensional inspection.

For structural parts with special requirements, 100% material hardness and conductivity (MS / M) shall be tested.

It is necessary to check the material certificate and surface treatment COC.
