Fuchang Precision Products (Shenzhen) Co., Ltd. (hereinafter referred to as Fuchang Precision) was established in 2003. The company specializes in the manufacturing and operation of precision components, molds, fixtures, engineering plastics, and high-capacity disk drive components. Fuchang Precision operates an injection molding facility in Longgang District.
Customer Requirements & Pain Points
The quality issues of injection-molded parts are often hidden beneath the surface. Voids, shrinkage cavities, weld lines, and internal cracks—these defects concealed inside plastic components cannot be detected by the naked eye, calipers, or traditional visual inspections, yet they can become critical risks during product assembly and use.
Fuchang Precision's products include precision components and high-capacity disk drive parts, both of which require stringent dimensional accuracy and internal structural integrity. The key challenges faced by its Longgang injection molding facility include:
Real X-Ray Inspection Images of Injection-Molded Parts
Solution
Wahfei Technology deployed an offline Industrial X-Ray inspection system for Fuchang Precision. The system parameters were optimized according to the material characteristics and inspection objectives of injection-molded parts, enabling high-definition imaging of internal structures.
When X-Rays penetrate plastic materials, defects such as pores, shrinkage cavities, weld lines, and foreign inclusions create clear grayscale contrasts due to density differences. Engineers can visually assess internal quality without damaging samples. Compared with traditional sampling methods, this solution reduces inspection time per part to seconds and enables 100% coverage of critical products.

Automatic Annotation & Reporting
For precision component manufacturers like Fuchang Precision, the value of X-Ray inspection goes beyond merely 'finding problems'. It shifts quality control from After Shipment提前到During Production—intercepting defective products before they reach downstream customers and fundamentally reducing complaint and recall risks.
Industry Insight: Where Does the Real Gap in Injection-Molded Product Quality Control Lie?
In the injection molding industry, 'appearance qualified' never means 'quality qualified'. A defect with a pore diameter of less than 0.3 mm may show no issues during assembly but can cause fractures after vibration, temperature fluctuations, or prolonged stress. The cost of tracing such problems is often dozens of times higher than the inspection cost.
More importantly, injection molding processes inherently exhibit batch-to-batch variation. Small changes in melt temperature, mold temperature, or holding time can affect internal structures. Quality systems relying on experience and visual sampling essentially replace process management with outcome management, whereas X-Ray inspection bridges the two by both intercepting defective products before shipment and identifying process bottlenecks through defect distribution patterns.
A Question Worth Considering: How many internal defects in your injection-molded products are discovered only by your customers? If the answer is not zero, the ROI of introducing X-Ray inspection may be achieved much faster than expected.
