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.
Richfields Corporation uses decades of experience in manufacturing unscrewing plastic injection molds. The output is molds that are used for the production of internal threaded plastic injection parts. External threaded plastic injection does not need to be produced using unscrewing injection molds.
We specialize in plastic injection molding for a wide range of OEM applications, offering machines from 60 to 3,300 tons to accommodate diverse production needs. Whether creating tight-tolerance components with strict quality control or cost-effective general plastic parts, our flexible approach ensures consistent, high-quality results for every project.
Richfields offers advanced spray painting and pad printing services, utilizing state-of-the-art technologies like tunnel conveyors and multi-color applications to enhance efficiency and reduce costs.
