Internal Gas Assist Injection molding
As the industry leader in gas assisted plastic injection molding, Sajar Plastics has extensive molding capabilities to meet the diverse needs of our customers.
As the industry leader in gas assisted plastic injection molding, Sajar Plastics has extensive molding capabilities to meet the diverse needs of our customers. Gas assisted injection molding can improve dimensional stability and lower costs over traditional manufacturing techniques such as structural foam molding and thermoforming. By injecting a controlled stream of gas into the mold, thick walls are created with hollow sections that save on material, shorten cycle time, and reduce the pressure required to mold the large plastic parts with complex designs and attractive surface finishes. All of these benefits are realized without any detriment to the structural integrity of the molded component.
We offer both internal and external gas assisted injection molding which allows us to create a myriad of complex part geometries not previously achievable by injection molding. Instead of requiring multiple parts that must later be assembled, supports and stand-offs are easily integrated into a single mold without the need for complex coring. Multiple injection molding machines are capable of producing parts from 10″ to 80″ long and from 10″ to 70″ wide. Our customer base includes OEM producers of retail kiosks that provide automated services, laboratory and diagnostic equipment designers, medical equipment manufacturers, and large office equipment companies. In addition to gas assisted molding, traditional injection molding and structural foam molding are available. Value added services including painting, inserting, printing, assembly and packaging provide customers with a single source for turnkey injection molded parts.
