How can we help?

Early-Stage Engineering Support

General Pattern Company offers a dedicated division focused on quick turnaround, cost-effective solutions that can facilitate evaluation of a part’s form, fit and function.  We offer a full range of technologies from plastic injection molding prototyping, polyurethane casting, roto molding, vacuum-forming to a full range of additive manufacturing, including traditional CNC machining and 3D printing.

Our commitment to innovation and excellence in the plastics industry enables us to be your solution for early development needs, making your idea/concept a reality. We understand the importance of verifying the design and function before investing in tooling, or the requirement of workable parts for tradeshows or regulatory approval.  With over 50 years of experience of on-demand solutions, our prototype division along with the flexibility of a full range of secondary operations will get parts in your hands quickly and with no need to compromise on your design.

FAQs

Our turnaround time varies based on the complexity of the project and the chosen prototyping method. Generally, we strive for industry-leading speed, ensuring you receive your prototype in the shortest possible time without compromising quality.

CNC machining and 3D printing serve different purposes in the prototyping journey. CNC machining is ideal for producing precise, functional components, while 3D printing excels in creating complex geometries quickly. The combination of both technologies allows for a comprehensive and efficient prototyping process.

The finished dimensions of urethane cast parts depends on the accuracy of the master model, part geometry and casting material. In general, a shrinkage rate of +0.15% is expected. 

Absolutely. Our tooling solutions are tailored to meet the unique requirements of each project. Whether you need molds for mass production or specialized tooling for a particular manufacturing process, our team works closely with you to deliver customized solutions that optimize efficiency and maintain high-quality standards.

Our services are designed to streamline the product development and manufacturing processes. By reducing lead times, minimizing design modifications, and optimizing manufacturing efficiency, we help you save both time and resources. The result is a cost-effective journey from prototype to production without compromising on quality.
