Services We Offer
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.
Overmold
Insert or overmolding 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.
