Insert Injection Molding Is Growing-Grow With It

The trend toward insert injection molding and overmolding is growing as manufacturers are looking for higher quality with more automation. It makes perfect sense, if you can mold around an insert and obtain a better part at a reduced overall cost, why not?

These clutch parts are a great example of insert molding. It does require a higher level of moldmaking in order to accomplish this, but the finished product is much better. Many automotive parts are made using insert injection molding. Rotary presses, shuttle molds, stack molds and hand loaded inserts are just some of the methods used.

Medical Molding Is A Growing Market For Insert Molding

The medical market presents a great opportunity for insert molders. Every year more and more devices are designed to be manufactured as a one-piece unit. It is safer and provides a cleaner part. Some molders are misinformed by thinking that all medical parts require a "white room." This is just not the case, as there are many parts that do not require anything more than a "clean room."

Thermosetting Plastics Are A Huge Market

Electrical switches and connectors of all kind are made using insert injection molding. The connectors and plugs are molded as one piece with the thermoset plastic and are nearly unbreakable. Special injection presses are required, or at least extensive modifications must be made to existing molding machines, in order to injection mold thermoset plastics.

 Many companies have found that the only way to win contracts is by offering a complete program of insert molding, inspection and shipping. This can require a substantial investment that might include special presses, "A" or "B" side mold halves, optical scanners, label making equipment, and packaging equipment.

One stategy is to build the molds in house, set up a manufacturing cell and test run everything extensively. Once everything has been approved, it can be move entirely to a less costly area. This helps eliminate the problems associated with unskilled help or a lack of communication. Once the program is up and running it should be a matter of maintenance and upkeep.
