Case analysisThis product is an automotive connector part. Complex structure and strict size requirements make mold design and processing and injection molding difficult.
After the first round of mold test size report came out, it was found that there was a large deviation between products of No. 2 and No. 3 mold cavities and No. 1 and No. 4. Such a situation has a great influence on next step of mold size adjustment.
Case study process• Based on filling balance being adjusted to be good, it is judged that during packing process, product variability between cavities due to differences in feeding and cooling processes is caused. By analyzing data from following temperature sensors, two of cavities have a lower mold temperature than the other two. After inspection and adjustment of cooling water circuit, temperature of four cavities is adjusted to same level.
Connector injection molding application case summaryManufacture of connectors usually corresponds to tight dimensional tolerances and quality consistency requirements. Especially for automotive connector industry, long project development cycle and high quality cost (zero defective products required for shipment). Introduction of cavity sensor technology has greatly enhanced competitiveness of such injection molding companies.
A. Enter into in-depth data analysis, obtain stable manufacturing process, shorten project development time, reduce number of mold changes and costs.
B. Automatically separate suspicious parts, eliminate cost of manual selection, realize online inspection of each part to ensure zero defective parts and avoid cost waste of batch scrapping.
C. Through sensor data to control injection molding machine, valve needle hot runner and other equipment to realize full closed-loop control of injection molding, so as to reduce production defect rate to a minimum. It has become an important link in upgrading of industrial technology.
