Penz Products,Inc.

Plastic Fabrication of a Radome for the Locomotive Industry

Having a modern, well-equipped facility and a staff of seasoned manufacturing professionals gives Penz Products a completive edge when it comes to thermoforming complex, close tolerance parts. The Radome pictured here functions as a protective weatherproof enclosure for a radar antenna located on top of a locomotive. High quality tooling was critical to the process and our technicians were given the opportunity to demonstrate their skills when fabricating the sophisticated mold required for this project. With a tolerance requirement of ±.005 this job required our best effort.

Working with a customer drawing our toolmakers crafted the geometrically complex form to exactly match the engineering specifications. Meanwhile, our materials experts calculated the optimal processing temperature for delivering a smooth, high-gloss finish while maintaining the strength and impact resistance properties of the ABS plastic. We used our large single-shuttle thermoforming equipment to manufacture the 5” x 61” x 5” enclosure. Continuous in-process testing and inspection ensured we maintained dimension and thickness tolerances and achieved the desired surface finish requested by the customer.

Within a 5 week turnaround, our high quality workmanship and attention to detail made this project a success. If you are interested in learning more about this project or our precision thermoforming services contact us today.
