Comparison of insert injection molding and post-injection assembly

Insert injection molding is to pre-place the insert into the mold cavity, and then add the melted plastic into the mold cavity to make an insert injection molded part. Generally speaking, injection molded inserts can be metal, ceramic, or other plastic products. Next, we discuss the comparison between the injection molding of the lower insert and the assembly after injection molding. Insert injection molding is an automated production method with high production efficiency, but the cost of equipment is much higher. Assembly after injection is a manual method, so the cost of the equipment is lower, but the production efficiency is lower. How to choose the production method needs to be considered by the factory. If the customer's demand is small, it should be better to adopt the method of assembly after injection, because it saves costs. If the customer's demand is large and it is a long-term stable demand, then the insert injection molding method will be better, the scale production cost is low, and the efficiency is high.
