No Job Is Too Big or Too Small!
Carlisle Plastics Company expertly manufactures PVC plastic caps tailored to non-standard shapes, sizes, and custom specifications. All our plastic caps are fully customizable—covering everything from unique shapes to specific colors, dimensions, and thicknesses. Whether you need a custom shape, size, or specific material properties—we deliver more than just off-the-shelf solutions.
What “Custom” Really Means to Carlisle Plastics Company
Beyond shape: While “custom” typically refers to odd shapes or non-standard sizes, it also includes:
- Length and thickness: Specify cap wall thickness and height or length for a perfect fit.
- Color choice: Pick from our extensive range of standard stock colors or request a precise custom color match.
- Durometer (hardness): From soft and flexible to firm and tough, we can match your requested material flexibility.
- Material Additives: UV stabilizers, flame retardants, Food Grade (FDA-approved ingredients), phthalate-free plasticizers.
Customizing standard shapes: Even our standard cap styles (round, rectangle, square, etc.) can be fully customized in all the above areas to your requested specifications. Need a round cap in a specific thickness and durometer, in Teal? Absolutely possible!
