We are a full-service plastic thermoforming design and manufacturing company that specializes in supplying custom molded, engineered plastic components at a competitive price.

ENGINEERING & DESIGN
From material selection to final component design, our team is dedicated to supporting your cost and fit/form/function objectives.

We make all tooling in-house – significantly reducing time to market on projects. Our on-site engineering team, pattern shop, and state-of-the-art foundry offer a unique advantage for tooling production and development that most thermoformers do not have.

We are experts in both high and low volume thermoforming and can form plastic parts ranging from .060” - .350” with complex geometries.

CNC TRIMMING & ROUTING
Utilizing the most innovative 5-axis equipment and tooling techniques, we optimize cycle times for 5-axis trimming and are able to route flat sheet stock such as HDPE (Starboard), ABS, and other plastic materials.

SECONDARY OPERATIONS
Complex assembly, hidden fasteners, laser etching, bonding plastics/metal, barcoding, prototyping via tooling and 3d printing, component sourcing.
