We turn ideas into reality

At Elfy's we understand the importance of a fast turnaround, taking great pride in our process efficiency. We stock a wide variety of polymers in-house and will obtain any material needed for your project. Our 12,000 sq. ft facility houses 8 injection molding machines, 3 CNC mills, sinker EDM, fully furnished manual machine shop and much more. 

With the recent acquisition of Elfy's by Westfall-Technik, our capabilities are vastly expanded. As part of an international network of plastics experts with ISO 9001 & ISO 13485 there is nothing we cannot mold for you!

Tooling Design

Your design is finalized and ready to take steps toward production.  Elfy's is here to help.  We have an intimate understanding of the practical considerations inherent to effective mold design.  Leveraging this knowledge, we can identify issues before they arise and ensure your product finds success in production.



Elfy's will produce, post-process, and package small batch production runs. Marketing value aside, there are massive benefits to be reaped when manufacturing domestically. Direct lines of communication save time and money when executing quality control, design changes, and part shipment.



Need your design digitized?  Whether your latest model is hand-carved, sketches on paper, or anything of the like, the design team at Elfy's will translate your work into an accurate computer model and get it on the fast track for injection molded success.
