QC

For product materials and product quality, we strictly implement LJZ inspection procedures and standards or ISO related standards, which include material inspection reports, FAI, CMM final inspection reports, and corresponding reports required by clients from various industries, such as PPAP, FMEA etc. Our ultimate goal is to make our product 100% safe to use.

Quality Inspection and Testing

• IQC

All incoming materials must be inspected by spectrum detector to ensure the authenticity.

• In-Processing-Inspection

Each product needs to go through a first article inspection (FAI) and be verified by engineering or quality managers.

• Inventory check

Before warehousing, 100% of the products must be inspected

• Pre-shipment inspection

Check again and record the delivery report before shipment

• Check on Testing Equipment

Regularly calibrate and identify inspection on equipment

• Our Test Tools and Equipment

Calipers

Inside/Outside diameter micrometer　 

Pin gauge/Gauge block / Plug gauge 

Thread/plug gauge (Metric/inch)

Projector

Material spectrometer　 

Hardness tester

• CMM

It is a device accurately measures the geometry of an object along X, Y and Z axes using a touch-trigger, scanning or vision probe to take a series of precise points on the surface of some complex and precise workpieces. For some complex and precise parts, it can complete parts inspection, shape measurement, process control and other tasks through continuous scanning. Our CMM is now widely used in inspecting precision parts, mold and moldings.

• Inspection of Product Appearance and Packaging

After finishing the surface treatment of parts, it is necessary to check whether the size and appearance meet the requirements. Customized packaging ensures that the product will not be damaged during delivery.

• ISO Certification

Improving customer satisfaction is our first priority, meanwhile, we fully compliant with the latest ISO requirements to evaluate and prevent any possible risks before production, which enable us to offer our customers with defect free products and services. Besides, regularly follow-up visit, telephone, survey are our tradition to continuously improve and upgrade our team.
