Manufacturing capability
Plastic Extrusion
Plastic extrusion is a continuous manufacturing process used to produce profiles, tubes, sheets, and other products with consistent cross-sectional geometry. It is widely used for industrial seals, protective profiles, pipes, cable coverings, and custom thermoplastic components requiring repeatable dimensions.

Manufacturing overview
Plastic extrusion forces heated polymer material through a shaped die to create a continuous product.
Common applications include tubing, pipes, profiles, sheets, films, cable insulation, and industrial protective components.
Suitable materials include PVC, polyethylene, polypropylene, ABS, TPU, and selected engineering thermoplastics.
Manufacturing feasibility depends on polymer rheology, die geometry, cooling conditions, line speed, and dimensional requirements.
Design considerations include wall thickness, profile complexity, shrinkage, dimensional stability, and material compatibility.
Co-extrusion may be used to combine compatible materials or functional layers in a single profile.
Buyers should provide cross-sectional drawings, material specifications, dimensions, tolerances, color, cut lengths, quantities, and functional requirements.
Where applicable, requirements may include pressure ratings, electrical insulation, chemical resistance, or flame performance.
Quality control may include dimensional measurement, wall thickness verification, visual inspection, and mechanical testing.
Metraxio supports plastic extrusion RFQs for custom profiles, tubes, and continuous polymer products.
Materials
A technical reference for buyers. It is not a statement that every facility offers every material.
Extrusion is used for thermoplastics that can be pushed through a die, including PVC, polyethylene, polypropylene, ABS and some engineering grades. Rubber and silicone are different materials and are not implied by this capability. Name the polymer and, when you have it, the compound or color. Filled or flame-retardant grades behave differently from the base resin.
Design considerations
The die sets the cross-section. Uniform wall thickness, hollows and tolerances on the profile decide whether a die is realistic. Cut length, straightness and a subsequent machining or punching step should be specified separately from the profile. A custom die is a tooling decision, so prototype quantities and production quantities need different expectations.
What to include in the manufacturing project
Provide a profile drawing with dimensions and wall thickness, the polymer, the color, the cut length, the quantity and any end machining. If a die already exists, say so. Delivery destination belongs in the project. Do not send an injection-molding tool as if it defined an extruded profile.
Buyer questions
Extrusion or injection molding?
Extrusion makes a constant cross-section in a length. Injection molding makes discrete 3D parts in a mold. If the part has bosses, clips or a closed shape that changes along its length, it is probably not an extrusion.
Can I extrude PEEK or POM?
Some engineering plastics are extruded as stock and then machined, and some can be profile-extruded under the right conditions. Name the polymer in the project rather than assuming this capability covers every engineering plastic.
What should I send for a custom profile?
A dimensioned cross-section, the polymer, the length, the quantity and the tolerances that matter. A 3D model of a short length is useful. A photograph alone is not a specification.
Is a profile die included automatically?
No. Tooling is part of the commercial discussion after the requirement is clear. The public page does not price a die or reserve a line.
