Inspection of Stainless Steel Inserts in Medical Injection Molding
In the field of medical injection molding, the inspection of stainless steel inserts is crucial. This is not only related to the quality and performance of the product but also directly affects the safety and health of patients.
1. Material Inspection
Chemical composition analysis: Use methods such as spectroscopy or chemical analysis to test the chemical composition of stainless steel inserts to ensure that meet relevant standards and regulations.
Material certification: Require suppliers to provide material certification for stainless steel inserts, including grade, chemical composition, mechanical properties, and other information.
2. Dimensional Inspection
Use precision measuring tools, such as calipers and micrometers, to accurately measure the dimensions of stainless steel inserts to ensure they meet design requirements.
For stainless steel inserts with complex shapes, a coordinate measuring machine can be used for high-precision measurement.
3. Appearance Inspection
Check the surface quality of stainless steel inserts, including gloss, flatness, no scratches, rust, etc.
Ensure that the edges of stainless steel inserts are smooth, without burrs or sharp corners, to avoid damage to the mold or product during injection molding.
4. Performance Testing
Conduct mechanical property tests such as tensile and bending strength to ensure that stainless steel inserts have sufficient strength and toughness.
According to the use environment and requirements of the product, conduct special performance tests such as corrosion resistance and high-temperature resistance.
5. Injection Molding Process Inspection
During injection molding, pay close attention to the fusion of stainless steel inserts and plastic, ensuring that the inserts are firmly embedded in the injection molded part without loosening or displacement.
Perform sealing tests, mechanical property tests, etc. on the injection molded product to verify the impact of stainless steel inserts on product quality.
