Custom Double Shot and Single Shot Injection Molding Manufacturing Services

At Elite Sales & Technology, LTD, we specialize in molding high quality, tight tolerance plastic parts in quantities from prototype to large scale production runs. Along with 120- to 300-ton single shot injection molding presses, we also have 50- to 500-ton double shot injection molding presses.

Our ISO-certified facility has two clean rooms (10,000 class and 100,000 class) where we can maintain precise environmental conditions to meet the strict requirements of the medical and electronics industries.

Working with all types of resin materials, we are capable of single shot injection molding and double shot plastic injection molding, insert molding, over molding, and liquid injection molding, which is particularly suitable for medical parts.

We also have four in-mold decorating lines that allow us to economically fabricate parts with different colors, textures, and long-lasting graphics. Skilled at producing waterproof parts and testing to IP68, we test 100% of these products. We also maintain four electronic manufacturing services (EMS) assembly lines to supply tested and approved units.

We offer engineering assistance to all our clients, and provide many value added secondary services. With many clients in the medical, electronics, automotive, and communication industries, among others, we have experience manufacturing parts used in appliances, office equipment, industrial controls, as well as consumer electronics and medical devices.
