Pioneering solutions in plastic extrusion machinery and processes for industry leaders worldwide.

The Plastic Extrusion Process

Plastic extrusion is a high-volume manufacturing process where raw plastic materials are melted and formed into a continuous profile. This process is fundamental to producing a wide range of plastic products that are integral to modern industry.

Material Preparation

Plastic resin pellets are carefully selected and may be mixed with additives such as colorants, stabilizers, or reinforcing agents to achieve desired material properties.

Melting & Conveying

The plastic materials are fed into the extruder where they are melted and conveyed forward by a rotating screw within a heated barrel, ensuring uniform melting.

Learn more

Shaping & Cooling

The molten plastic is forced through a die that gives it the desired cross-sectional shape. The extrudate is then cooled and solidified, often through water baths or air cooling.

Learn more

Cutting & Finishing

The continuous extrudate is cut to the required length using cutting tools or saws. Additional finishing processes such as printing, punching, or assembly may follow.

Learn more

Quality Control

Finished products undergo rigorous quality checks to ensure they meet industry standards for dimensions, appearance, and physical properties.

Extruder: The Heart of Plastic Extrusion

The extruder is the central component in the plastic extrusion process. It is responsible for melting, mixing, and conveying plastic materials to form a homogeneous melt ready for shaping. Advanced extruders incorporate precision controls and state-of-the-art screw designs to optimize plastic processing.

Single & Twin Screw Designs

Single screw extruders are ideal for simple extrusion tasks, while twin screw extruders offer superior mixing capabilities for complex formulations and higher throughput.

Precision Heating & Cooling

Advanced temperature control systems ensure optimal melting and processing conditions for different plastic materials, minimizing degradation and ensuring product consistency.

High Torque Gearboxes

Heavy-duty gearboxes provide the necessary torque for processing high-viscosity materials and maintaining consistent output pressure.

Advanced Pipe Extrusion Process

1

Material Feeding

Plastic resin pellets are fed into the extruder hopper, often with precise gravimetric or volumetric dosing systems to ensure accurate material ratios.

2

Melting & Extrusion

The extruder melts the plastic material and pushes it through a die specifically designed to form the pipe's cross-sectional shape.

3

Calibration

The newly formed pipe passes through a calibration unit to ensure precise outer diameter and wall thickness through vacuum sizing or pressure calibration.

4

Cooling

The pipe is cooled in a water bath to solidify the plastic, ensuring dimensional stability and proper crystallization of the material.

5

Cutting & Stacking

The cooled pipe is cut to specified lengths using flying saws or rotating blade cutters and stacked for packaging.

Extrusion Blow Film Technology

Extrusion blow film technology is used to produce plastic films for packaging, agricultural, and industrial applications. This process creates high-quality, uniform films with excellent barrier properties and mechanical strength.

1

Material Extrusion

Plastic resin is melted in the extruder and forced through an annular die to form a tubular film (parison). The die gap and extruder output determine the initial film thickness.

2

Bubble Formation

Air is introduced into the center of the parison, inflating it into a bubble. The bubble is stretched both circumferentially (by the air) and longitudinally (by haul-off rollers).

3

Cooling & Collapsing

The bubble is cooled by air rings or water sprays, solidifying the plastic. The cooled bubble is then collapsed by nip rollers and flattened into a double-layered film.

Winding & Finishing

The flattened film is trimmed to the desired width and wound onto rolls. Additional processes such as printing, laminating, or slitting may be performed depending on the application.
