Injection molding is a method of industrial product modeling. The products are usually made of rubber injection and plastic injection. Injection molding can also be divided into injection molding and die casting.


● Shrinkage, shrinkage, non full mold, wool edge, weld mark, silver wire, spray mark, scorch, warpage, crack / rupture, dimension super difference and other common injection molding problems, as well as the solution for mold design, molding process control, product design and plastic materials.

● Reason analysis and solutions for the lack of glue and mold in plastic parts

● The reason analysis and Countermeasures of Mao Bian

● Reason analysis and solutions for surface shrinkage and shrinkage of injection molded parts

● Analysis of the causes of crazing (flower, water spray), scorching and air stripe and the Countermeasures

● Reasons for water ripple and streaks on the surface of injection molded parts and Solutions

● Analysis of the causes of water cut on the surface of injection molded parts (weld lines) and spray patterns (snake lines) and Solutions

● Reasons for surface crack (crack) and top White (top explosion) of injection molded parts and Solutions

● Reasons for surface color difference, poor gloss, color mixing, black stripe and black spot of injection molded parts and Solutions

● Examination and resolution of injection-molded parts' warpage and internal stress cracking

● Analysis of the causes and corrective actions for injection-molded parts' dimensional deviation

● Reason analysis and fixes for injection-molded components that stick, drag, and snag

● An examination of the causes of injection-molded parts' inadequate transparency and strength (brittle fracture) and potential solutions

● Analysis of the causes and countermeasures for plastic part peeling and cold spots

● Causes of subpar metal inserts in injection components and their remedies

● Reason analysis and corrective actions for glue leakage, nozzle drawing, nozzle obstruction, nozzle salivation (runny nose), and die opening trouble.


Using CAE mold flow analysis technology, the injection field problem may be resolved efficiently and fast.
