What should be paid attention to in the design of insert injection molding

Insert injection molding is an injection molded part in which the insert is placed in the mold cavity in advance, and then the plastic is wrapped around the insert to be molded. What should an insert injection molding plant pay attention to when performing insert injection processing? Precision-Focus on metal insert injection molding for more than 10 years, and has accumulated rich experience in customized processing. Next, Precision will analyze the precautions for injection molding of the lower insert. 1. The selection of insert materials. Copper, aluminum, steel, hard and different plastic parts, porcelain, laminated glass and plastics can all be used as insert materials. Among them, red copper is not rusty, corrosion resistant, easy to produce and process. The price is moderate and it is a common material for inserts. 2. The shape of the insert should be ring-shaped or axisymmetrical as much as possible, no sharp edges or sharp angles are allowed, so as to gather it in a symmetrical manner and avoid partial ground stress, which may seriously cause stress concentration. 3. Inserts also need to consider DFM metal material inserts are produced by drilling or stamping, so the shape of the insert must have excellent production and processing performance.
