Bruin Manufacturing is an ISO 9001:2015-certified manufacturer and has over 70 years of experience in small part injection molding. We are a custom injection molding company, and we specialize in those technical, more difficult parts. Bruin offers all services in-house. From help with part design, out to the tool shop, into a molding press and on to packaging and shipping your part out the door, it’s all done in one location! With Bruin's pioneered "lights out" system, we can meet the tightest tolerances, offer design flexibility and produce items with reduced cycle times and minimal labor content.
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!
A “small part” is defined as a part that fits on the palm of one hand while a “micro” part is smaller than a fingernail. The smallest part manufactured by Bruin so far has been 0.05 grams and the smallest tolerance has been less than 1/1000 of an inch. With nearly 60 plastic molding presses with sizes ranging from 25-121 tons, our capabilities include:
Bruin Manufacturing runs 24/6 with just one shift with employees in the plant. The other two shifts are done “lights out” with no employees present. This keeps our labor cost down and therefore, your part price lower. Other benefits of working with Bruin include:
