Running hot, Consistent Quality Injection Molding

With a pioneering hot-runner system, Bruin Manufacturing can meet the tightest tolerances, offer design flexibility, and produce items with reduced cycle times.

Our entire production process is unique. We’ve developed high-output automated process lines capable of fabricating parts with a high degree of precision, accuracy, and consistency with minimal operator oversight. This reduces labor needs, a cost reduction we happily pass along to our customers. Our custom plastic injection molding is unique in the industry, providing injection molded parts that are durable and efficient for your custom injection molding specifications. 

We feature a lights-out production concept, where machines run around the clock. Once the mold is created and processes are finalized, only one operator is needed for control and management.
