Extrusion Line Machines: Types, How to Choose, and 10 Manufacturers to Compare (2026)

Quick Answer: An extrusion line machine is a complete system that melts plastic, shapes it through a die, then cools, sizes and cuts or winds the product. This 2026 guide covers the main line types, compares ten manufacturers and explains how to choose a line: Coperion, battenfeld-cincinnati and Davis-Standard as international references, and Sino-Alloy, CYKF, Twin Screw, Chen Yu, Fong Kee, Chi Chang and Kung Hsing from Taiwan. Match the builder to your product family first, then request a quote for the whole line.

What Is an Extrusion Line Machine?

An extrusion line machine is a complete production system that melts plastic in a screw extruder, forces the melt through a die to form a continuous shape, then cools, sizes and cuts or winds the product downstream. Pipes, profiles, sheets, films, monofilaments and pellets are all made this way. A compounding or recycling line is simply an extrusion line whose product is granulate.

Types of Extrusion Line Machines

Pipe and profile lines. Counter-rotating twin screw extruders are widely used for rigid PVC pipe and profiles, while single screw machines are the usual choice for a PE extrusion line making HDPE pipe. Browse pipe and profile lines on PRM-Taiwan, or see our ranking of PVC extrusion machine manufacturers.

Sheet and board lines. Flat-die lines produce PP, PS or ABS sheet, hollow profile board and foam board. A co-extrusion machine adds skin or core layers, for example a three-layer ABS sheet.

Film lines. Blown film lines inflate a tube of melt and flatten it into film. Cast film lines extrude through a flat die onto chill rolls. Multi-layer co-extrusion combines resins for strength, barrier or cost. Our blown film extruder ranking covers that family in depth, and the film and sheet lines category lists machines by type.

Monofilament lines. These lines extrude and stretch round filament for products such as brushes, ropes and fishing line. See the monofilament extrusion lines category.

Compounding and pelletizing lines. Co-rotating twin screw extruders blend polymers, fillers and masterbatch, then strand, water ring or underwater pelletizers cut the product into pellets. Compare twin screw extruders by screw size and application.

Comparison Table

How We Picked This List

• A verifiable product family. Taiwanese entries follow the lines on each company's PRM-Taiwan page and its official site where one exists. International entries follow official sites.
• Extrusion lines are part of the company's positioning, not a side product. Companies whose listings showed only components or unrelated machinery were left out.
• The list spans line types: compounding, pelletizing, pipe, profile, sheet, film and monofilament, rather than ten versions of one line.

Research limitations: no lines were tested, and quotations, energy consumption, warranty and service coverage were not compared on a common basis, so confirm each with the supplier. The order groups manufacturers by line type, not by quality. No output, speed or price figures are quoted because no common test basis exists. Information checked as of 2026-11-02.

How to Choose an Extrusion Line

Buying an extrusion line means evaluating the whole system.

• Match the builder to your line type first. Different line types need different designs and downstream equipment. Shortlist by documented lines in your product family, not by company size.
• Quote the line, not the extruder. Ask every supplier to price die, calibration or casting, downstream equipment and controls together, with output stated for your material.
• Ask what happens with your recipe. Regrind share, filler loading and additives change screw design and output. Send your actual formulation and ask about a test run.
• Check energy per kilogram. Lines run for long hours, so ask for specific energy consumption on comparable products and check the assumptions behind it.
• Weigh turnkey support. For a new plant, a builder that can plan layout, utilities and training removes the riskiest interfaces from your schedule.

Frequently Asked Questions

What is the difference between an extrusion machine and an extrusion line?

The extrusion machine is the extruder itself: screw, barrel, drive and controls. An extrusion line adds everything that turns melt into product, including the die, calibration or casting, cooling, haul-off, and cutting or winding. Suppliers quote either scope, so always confirm which one a price covers.

Is an extrusion molding machine the same as an extruder?

The terms overlap. "Extrusion molding machine" usually points to the same screw-extruder equipment, with the die shaping a continuous profile. It differs from injection molding, where a closed mold is filled shot by shot.

Which extruder type do I need, single screw or twin screw?

Single screw extruders melt and convey many thermoplastics for pipe, sheet and film. Counter-rotating twin screws are widely used for rigid PVC, which benefits from gentle, even shear. Co-rotating twin screws are the common compounding tool for blending polymers, fillers and additives. Your material and product decide, and a supplier who asks about your recipe before quoting is a good sign.

Can one extrusion line run several products?

Within a family, often. A profile line can change dies between profiles, and a pelletizing line can switch recipes. Across families, rarely, because sheet, pipe and filament lines differ in downstream equipment more than in the extruder. Plan capacity per product family and ask what a changeover actually involves.

How do I compare quotes from Taiwan and Europe?

Send every supplier the same specification: product, material and recipe, target output, width or diameter range, and scope of supply. Then compare delivery time, service in your country and exactly what each price includes. Check differences in scope when comparing quotations.
