Profile extrusion is a continuous high-volume manufacturing process where a polymer material, enriched with the desired additives, is melted and pushed thru a die supported by a source of air to allow the hollow product to maintain its inside shape and not collapse in a vacuum. Continuous shapes in varying lengths can be produced quickly and efficiently. Various wall thicknesses, colors, textures and material modifications are available. We build our extrusion dies, calibrators, and plates in-house for quick turnaround and fast adjustments. Two or more machines can be used to feed a single die head in order to create multiple material components (e.g. combination of colors, functional materials, hard/soft combinations etc.). Custom materials and additives give the part additional performance characteristics, such as fire resistance, durability, anti-friction, or conductivity properties.
