Insert Molding

Insert Molding

Insert molding of metal components creates a permanent bond between plastic and metal in parts that require molded-in fasteners, anchors, hinges and electrical connectors. We have both horizontal and vertical presses with rotary shuttles for insert molding.



Overmolding rigid plastic substrates with thermoplastic elastomers can provide a soft feel, improve grip, weather seal, dampen vibration and protect against impact. A wide range of colors, textures and durometers are available. 


Lens Molding

Clear polycarbonates, crystal styrenes and acrylics are common choices for transparent lenses. We can help you select the right material for the optical clarity, transference, reflectivity and environmental resistance you need. We also have capability for assembly — including pressure testing for water resistance — and vacuum metallization, electroplating and hard coating services.

Engineered Polymers

Our plastic injection molding facility molds a number of high-performance, engineered resins for demanding shear, tensile and impact strength applications. These engineered polymers can also offer high heat deflection, chemical resistance and critical dimensional stability.

The list includes polyetheretherketone (PEEK), liquid crystal polymer (LCP), polyphthalamide (PPA), polybutylene terephthalate (PBT), polyacetal (POM), polysulfone (PSU), polyphenylsulfone (PPSU), polyethersulfone (PES), polyphenylene sulfide (PPS), polyamide (PA 6/6), polycarbonate (PC) and PC/ABS blends.

Support Services

We also offer a variety of support services to ensure efficient and high-quality production of your product.
