Injection Molding Overview
Injection molding is a forming process where molten material is injected into a mold and then cooled to form the desired end product. Injection molding is possible with several polymers (thermoplastics), including polymers produced with glass or metal additives. MW Components produces injection molded parts for several industries and applications using one or more injection molding processes—overmolding/insert molding, reel molding, and micro molding. These processes are most often used to create plastic optics and other injection molded parts for medical molding applications, though they can be used to mold polymers for a variety of industries.
In addition to the precision production of custom parts, our East Providence facility offers many additional services onsite, including analysis and testing like mold flow fill analysis, medical IQ/OQ/PQ validations, ultrasonic welding, FDM 3D printing (PLA, PPA, PC), and in-house toolroom for mold repairs and fabrication. We even offer in-house assembly and packaging.
