Straight Injection Molding Services
Injection molding is accomplished by forming molten plastic under pressure into a cavity formed between two matched metal mold halves. Once the plastic cools, the mold is opened and the parts removed.
Sajar Plastics has a wide range of injection molding machines and practices a wide range of injection molding processes in order to offer our customers the best combination of manufacturing process and properly sized production machine for each of their parts.
Gas Assist Injection Molding Services
Gas assist injection molding is a low pressure process that requires the injection of pressurized nitrogen gas into the interior of a mold.
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.
Structural Foam Injection Molding Services
Structural foam molding is a low pressure injection molding process that is capable of producing very large structural parts. The molten plastic is injected into a mold after being mixed with a blowing agent, causing the plastic to “foam.”
Injection Molding Services : Assembly and Finishing
Our decoration and finishing department’s exclusive goal is to make your equipment look better than your competitor’s. Your parts can be painted, electromagnetically shielded, inserted, printed, constructed into highly complex sub-assemblies, and packed to guarantee they arrive at your location looking as sharp as they did when they left Sajar.
Sajar Plastics provides plastic design and engineering services to assist customers in the development of large, complex, plastic components.
With Sajar’s guidance, customers can commonly consolidate many smaller parts originally intended to be assembled together into one larger part with a cleaner profile, thereby improving the aesthetic appeal of the entire unit and reducing subsequent processing.

Our Rapid Heat-Rapid Cool with Gas Assist process achieves a Class A type surface without sink. Adding the Heat and Cool portion to the molding of the part with Gas Assist can take your designs to the next level and eliminate paint! We can also achieve this with glass filled materials.
