Features:
a) Extruding device adopts variable frequency motor which can satisfy the requirements of rotation change of screw during blowing process. Screw with big slenderness ratio can be used to process many kinds of materials and has strong plasticizing ability, high production and low energy consumption. The barrel adopts resistance heater which is controlled by computer and heats quickly, stably, and equably.
b) By installing different head in combined extrusion system between two extrusion machines, they can blow products with view strip line or double layers.
c) Mould clamping device adopts toggle type and linear guider. Double station, the speed of mould platen moving more quickly and stably.
d) Improved design of hydraulic oil loop. Power saving, rapid and stable.
e) Installation and maintenance of hydraulic elements are convenient. Equipped with removable and mobilizable oil tank.
f) The whole machine is controlled by computer. The hydraulic system adopts double proportional control. This machine has fault automatic alarm, reliable operation, high automation, and data memory of 40 sets of moulds.
g) Three operation modes-“Manual”, “Semi Auto”, “Full Auto”, are allowed to select.
h) Safety door adopts electric and mechanical safety devices (no mould closing happens when safety door opens) which make operation safe and reliable.

Applications:
Extrusion molding machines play a pivotal role in manufacturing processes by producing continuous profiles with a consistent cross-section. These machines find various applications in several industries:
1. Plastic Industry
- Pipes & Tubes – PVC, HDPE, and PP pipes for plumbing, drainage, and electrical conduits.
- Sheets & Films – Packaging films, agricultural films, and thermoforming sheets.
- Profiles – Window frames, door seals, and decorative trims.
- Filaments & Fibers – Synthetic fibers for textiles, ropes, and 3D printing filaments.
- Cables & Wires – Insulation coating for electrical wires and cables.
2. Rubber Industry
- Tire Manufacturing – Rubber strips for tire treads and sidewalls.
- Seals & Gaskets – Automotive and industrial rubber seals.
- Hoses & Tubing – Fuel hoses, hydraulic tubes, and medical tubing.
3. Food Processing
- Extruded Snacks – Puffed cereals, pasta, and pet food.
- Confectionery – Licorice, chewing gum, and candy bars.
- Textured Protein – Plant-based meat alternatives.
And that's only the beginning! Extrusion molding finds application across a wide range of industries, from pharmaceuticals to construction and automotive sectors.
Advantages of Extrusion Molding
- High Efficiency – Continuous production with minimal downtime.
- Versatility – Ability to process various materials (plastics, rubber, food, etc.).
- Cost-Effective – Low waste and high-volume output.
