When a standard plastic profile doesn’t meet your product’s requirements, custom plastic extrusion provides a flexible solution. This manufacturing process allows engineers and product designers to create plastic profiles in specific shapes, sizes, materials, and performance characteristics.
Whether you need tubing, channels, seals, trim, or another continuous plastic profile, custom extrusion can help turn your design requirements into a reliable finished component.
What Is Custom Plastic Extrusion?
Custom plastic extrusion is a manufacturing process in which plastic material is melted and pushed through a specially designed die to create a continuous profile with a specific cross-sectional shape.
Unlike off-the-shelf plastic products, custom extrusions are designed around the application. Factors such as dimensions, material properties, color, flexibility, temperature resistance, and durability can all be considered during the design process.

How Does the Plastic Extrusion Process Work?
The extrusion process typically involves several key steps:
- Material selection: A plastic resin is selected based on the product’s performance requirements.
- Melting: The plastic material is heated and processed through an extrusion machine.
- Die forming: The melted plastic is pushed through a custom die that determines the profile’s shape.
- Cooling: The extruded profile is cooled to stabilize its dimensions.
- Sizing and finishing: The product may be cut, shaped, inspected, or finished according to specifications.
Working with an experienced extrusion manufacturer is important because the die design, material selection, processing conditions, and dimensional requirements can all affect the final product.
What Products Can Be Made With Plastic Extrusion?
Custom extrusion can be used to manufacture a wide range of continuous plastic profiles, including:
- Plastic tubing and hoses
- Channels and tracks
- Seals and gaskets
- Protective edging and trim
- Plastic profiles
- Structural components
- Custom shapes for industrial applications
J & L also offers coextrusion and other extrusion solutions designed for specific product and application requirements.
Coextrusion is a manufacturing process where two or more molten polymers are formed together through a single die to create a unified, multi-layer profile. This approach can provide different material characteristics within the same finished component.
Why Choose Custom Plastic Extrusion?
For engineers and product designers, custom extrusion can provide several advantages. It allows manufacturers to develop components with precise dimensions while selecting materials based on the application’s functional requirements.
Custom extrusion can also be an efficient option for high-volume production because the process continuously creates the desired profile. With the right design and material, extruded plastic components can provide consistent performance while helping control manufacturing costs.

Before beginning a custom extrusion project, engineers and designers should consider:
- Required dimensions and tolerances
- Plastic material and performance requirements
- Operating temperature
- Chemical or environmental exposure
- Flexibility or rigidity
- Color and appearance
- Production volume
- Required finishing or secondary operations
Providing detailed drawings, specifications, samples, or application requirements can help an extrusion manufacturer determine the best approach for your project.
