Precision is KEY
(see what we did there ;) )

CNC routing plays a key role in how precision finished parts come together. Whether cutting complex geometry from flat sheet or trimming vacuum formed parts, our 3-axis and 5-axis capabilities allow us to meet exact print specifications with repeatability and accuracy.

Our in-house CNC capabilities gives us full control over quality, lead times, and repeatability from forming to finish.

The people behind the parts.

Every project that moves through our shop involves skilled hands, careful setup, and attention to detail at every stage.

Meet Barb, our thin-gauge forming line production specialist. For more than three years, she’s brought both experience and a great attitude to the shop floor—helping keep production running smoothly and consistently.

From forming to final inspection, it’s people like Barb who make the difference at Key Industrial Plastics, Inc.

Material matters:

PETG (Polyethylene Terephthalate Glycol), a versatile material known for its excellent clarity and ease of formability.

Compared to ABS, PETG offers superior transparency while still maintaining solid impact resistance. Unlike acrylic, it’s less brittle and more forgiving during the forming process (especially useful in thin-gauge packaging applications) . And while polycarbonate is extremely tough, PETG forms at lower temperatures, processes more easily, and is a cost-effective choice for clear applications.

PETG isn’t just a “clear” option. It’s also available in black, white, and custom colors. It can be sourced in both heavy-gauge sheet and thin-gauge roll stock, making it adaptable for a wide range of applications and production volumes.

Its combination of clarity, durability, formability, and economic efficiency makes PETG a strong option when appearance and performance both matter.

Material selection is always application-driven at Key Industrial Plastics, Inc.

Heavy Gauge Vacuum Forming

A cut sheet is evenly heated to a precise forming temperature, then vacuum pressure draws the softened material tightly over the mold to capture its exact shape and detail. The part is then cooled under control, allowing it to become a rigid, durable, functional component ready for trimming and final use.
