JG Plastics are experts when it comes to precision injection molding. We can help with your part design and material selection, and we can help you determine the best tooling configuration to create your complex, precision component. When you really need your part to work, trust the experts at JG Plastics.

Our molding technicians and tooling design engineers will assist you from design concept to part completion. JG Plastics provides molding and tooling services which ensure consistent, high quality parts. Our state of the art facility houses modern injection molding equipment and a Class 10,000 / ISO Class 7 cleanroom to manufacture parts for the aerospace, defense, electronic, and medical industries.

Our toolmakers are able to build injection molds with the highest degree of precision, often with tolerances of just 0.0001". Precision molds are the just first step in molding sub-miniature, micro, and nano components. Scientific molding, statistical process control and mold/process qualification testing are all important elements in the total package.

If you require overmolding, insert molding, or two-shot molding, JG Plastics has the experience to create the tooling and molding processes to get your job done right.

Material properties and plastic rheology are very important when developing precision injection molded parts. When your part has to meet the specific regulations of your industry, having the right material is essential. Correct storage, handling, drying and processing of today’s highly engineered resins is critical to the production precision molded parts. At JG Plastics, we pay attention to all aspects of the molding process, from tooling and material, to machine and processing.

JG Plastics operates a state of the art manufacturing facility located in Southern California. Our molding is performed on a comprehensive range of horizontal and vertical injection machines, from 20 through 650 tons.
