Injection Molding

Injection molding along with extrusion ranks as one of the prime processes for producing plastic articles. It is a fast process and is used to produce large numbers of identical items from high precision engineering components to disposable consumer goods.

Injection molding manufacturing and production is the core of North Bay Plastic Molders’ business. We specialize in rapid injection mold, custom injection mold, and plastic injection molding and are structured to quickly produce affordable pre-hardened-steel plastic injection molds for production parts. The range of injection molded products we can manufacture is comprehensive and we serve a cross section of markets including the mining, construction, electronics and recreation industries. Our standard lead-time is within two days to five weeks – regardless of the size or complexity of your parts.

Custom molding is our speciality and we can produce either complete injection mold products or component parts. In addition to our large selection of standard materials and colors to choose from, we also welcome your requirements for engineered specialty resins and/or special colors. Select from our standard surface finishes, or specify your requirement.

Our sole purpose is to quickly supply you with affordable, high-quality plastic injection molded parts to support your requirements for low and high-volume production.

Prototype Tooling

North Bay Plastic Molders provides quick-turn thermoplastic injection molding often used for prototyping, bridge tooling and short-run manufacturing up to 10,000+ parts. We use advanced aluminium alloy molds that allow us to eliminate the costly and time-consuming custom engineering that normally goes into the development of tooling. North Bay Plastic Molders offer a broad selection of engineering-grade resins that produce molded parts that are strong and can have excellent finishes.

Quick-turn injection molding uses the industry standard production process for parts, so it’s an excellent predictor of manufacturability when you move to large-scale production. At North Bay Plastic Molders we support an ever-increasing maximum part size and degree of complexity, and continue to introduce new materials that help designers and engineers make better products.


Small quantities of prototypes are often manufactured through our machining process, but injection molding is also utilised for a few reasons. Product developers can get a short run of parts made in real plastic and liquid silicone rubber materials while simultaneously vetting a part design for moldability.


Bridge tooling helps fill the manufacturing gap that occurs while waiting three to four months for production tooling to be ready. Our injection-molding process uses aluminum molds to quickly and efficiently produce a run parts for pilot production or market testing before large-scale production begins.
