Strengthening Quality Control Foundation | Shizi Precision Improves Precision Testing Laboratory, Strengthens Dimensional Accuracy Control of Components

To continuously improve the delivery quality of precision components, Dongguan Shiwei Precision Technology has completed a new round of equipment additions and process standardization upgrades in its testing laboratory, further enhancing the full-chain inspection capabilities for incoming materials, processes, and finished products.

To meet the high-precision machining requirements for RF cavities, water-cooling plates, and special-shaped structural parts, the company has added high-precision height gauges, roughness testers, and precision micrometer sets, while optimizing the operational standards for coordinate measuring machines. For water-cooling heat dissipation plates, the airtightness testing station has been improved, enabling pre-screening of leakage risks in the cooling cavities.

In the precision CNC machining industry, the belief that 'machining accuracy relies solely on final inspection' is a common misconception. Shiwei Precision implements a process patrol inspection mechanism, conducting stress deformation predictions after rough machining and real-time dimensional fluctuation monitoring during finishing to proactively avoid batch defects. At the same time, inspection reports for each batch of products are fully retained, allowing customers to trace production data.

In the future, the company will continue to promote digitalization of quality control, continuously narrowing dimensional error margins, and providing higher stability precision component machining services for customers in the communication, new energy, and medical equipment sectors.
