A plastic extrusion machine melts thermoplastic and forces it through a die to form a continuous product — cable insulation, tubing or profile. Sai Extrumech designs and builds plastic extrusion machines and complete lines for the wire, cable and tubing industries, from a single extruder to a full turnkey line, engineered around your material and output.
What Is a Plastic Extrusion Machine?
A plastic extrusion machine feeds polymer pellets into a heated barrel where a rotating screw melts, mixes and pressurises them, then pushes the melt through a shaped die. The product is cooled, pulled at a set speed and cut or wound. For the full process, see how plastic extrusion works; for a neutral overview see Wikipedia.
Plastic Extrusion Machines We Manufacture
We build plastic extrusion machinery for wire, cable, tubing and R&D:
- Single-screw plastic extruders — 25–150 mm, with screw and barrel geometry matched to your polymer
- Complete cable & wire extrusion lines for power, building, solar, submersible and LAN cables
- Sioplas / XLPE lines for medium-voltage cable
- Medical & industrial tubing lines for catheter, PVC and PU tubing
- Lab & pilot plastic extruders for film, sheet, tube and compounding trials
- Crossheads, tips & dies and other tooling for any extruder
Plastics We Process
Our plastic extrusion machines run PVC, PE (HDPE/LDPE), PP, XLPE, nylon, PU, TPU and PEBA. Because the screw and barrel are matched to the compound, each machine is tuned for the material you actually process rather than a generic average.
Why Choose Sai Extrumech
- Custom-engineered for your material, product and output — not a fixed model
- In-house design, manufacturing, assembly and testing — no bought-in sub-assemblies
- 25+ years as an extrusion machine manufacturer in India with exports to the UAE, UK, South Africa, Bangladesh, Nepal and Sri Lanka
- Backed by spare parts and after-sales service
Frequently Asked Questions
What is a plastic extrusion machine?
A plastic extrusion machine melts thermoplastic pellets in a heated barrel and forces the melt through a die to form a continuous product with a fixed cross-section, such as wire and cable insulation, tubing or profile. A complete plastic extrusion line adds a crosshead or die, cooling, haul-off and take-up.
What can a plastic extrusion machine make?
With the right tooling and downstream, a plastic extrusion machine can produce cable insulation and sheathing, medical and industrial tubing, and – at lab and pilot scale – film, sheet and pelletized compound. The extruder stays the same; the die and take-off change with the product.
Which plastics can be extruded?
Common extruded thermoplastics include PVC, PE (HDPE/LDPE), PP, XLPE, nylon, PU, TPU and PEBA. We match the screw design and barrel to your specific compound for the best output and melt quality.
Do you build custom plastic extrusion machines?
Yes. We design and build each plastic extrusion machine around your material, product and output rate rather than selling a fixed model, and we manufacture the matching screws, barrels and crossheads in-house.
How much does a plastic extrusion machine cost?
The cost depends on the extruder size, line speed, downstream equipment and tooling – a compact lab extruder costs far less than a large, high-speed production line. Share your product and target output through our contact page and we will provide a quotation.
