Air Assist

Gas Assist Injection Molding is the process in injection molding wherein nitrogen gas is injected through controlled high pressure into the tool during the injection process. Richfields usually uses this process for plastic parts that are considered bigger or thinner than usual, under industry standards. There are a number of benefits to using Gas Assisted Injection Molding process.

Overmold

Insert or over molding is used when the design of your products needs to combine materials with different specifications into one finished product. It is used when a single shot is not enough for the complexity of the product. The finished product of an insert molded or over-molded part is a single piece with plastic molded around the insert. This is done by incorporating the insert into a tool and then over-molded to form the final part. The insert used in over-molding is usually made of metal or plastic.
