Quality Control

Yuhuan Chihong Auto Parts Co., Ltd

At Chihong, quality is at the heart of everything we do. We maintain full control from material sourcing to final inspection, supported by a documented and traceable quality system.
Raw Material Control:
ZL11 alloy is in-house cast, treated with T6 heat process and sandblasted to guarantee strength and anti-corrosion performance.
In-Process Quality Control:
Rough/precision turning, deep drilling, CNC machining, and special hand-operations are all subject to process-specific inspection points.
Comprehensive Testing Framework:
✔ Manual porosity inspection per unit
✔ Sealing and vacuum test per batch
✔ Endurance/life testing for selected items (400,000+ cycles)
✔ Final visual, dimensional, and packaging check with tracking code

production process

We insist on full in-house production. Every pump begins with raw material casting and undergoes 100% self-controlled processing—ensuring consistent quality, traceability, and optimization. Our production process involves 12 meticulously controlled steps—from raw material casting and rough turning, to CNC precision machining, deep hole drilling, special manual processing, and multi-stage inspections such as porosity check, sealing test, vacuum test, and life-cycle simulation. This integrated workflow guarantees full traceability, dimensional accuracy, and consistent product reliability across every batch.
