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.
Learn moreMelting & 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 moreShaping & 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 moreCutting & 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 moreQuality Control
Finished products undergo rigorous quality checks to ensure they meet industry standards for dimensions, appearance, and physical properties.
Learn morePackaging & Distribution
The final products are packaged according to customer specifications and prepared for distribution to various industries worldwide.
Learn moreExtruder: 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.

Extruder Applications by Industry
Extrusion Pipe Manufacturing Technology
Plastic pipes produced through extrusion are essential components in various industries, offering durability, corrosion resistance, and cost-effectiveness. Advanced pipe extrusion lines ensure high precision and consistency in pipe dimensions and quality.
Advanced Pipe Extrusion Process
Material Feeding
Plastic resin pellets are fed into the extruder hopper, often with precise gravimetric or volumetric dosing systems to ensure accurate material ratios.
Melting & Extrusion
The extruder melts the plastic material and pushes it through a die specifically designed to form the pipe's cross-sectional shape.
Calibration
The newly formed pipe passes through a calibration unit to ensure precise outer diameter and wall thickness through vacuum sizing or pressure calibration.
Cooling
The pipe is cooled in a water bath to solidify the plastic, ensuring dimensional stability and proper crystallization of the material.
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.
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.
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).
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.

Profile Extrusion Technology
Profile extrusion is a versatile manufacturing process used to create plastic profiles with complex cross-sectional shapes. This technology is widely used in construction, automotive, and consumer products industries.
Key Components of Profile Extrusion
Extruder
Melts and conveys the plastic material to the die. Single or twin screw extruders are used depending on the material and profile complexity.
Die
Shapes the molten plastic into the desired cross-sectional profile. Dies are custom-engineered for each specific profile design.
Calibration Unit
Cools and stabilizes the extruded profile to maintain precise dimensions and surface finish.
Haul-Off Unit
Pulls the extruded profile through the calibration and cooling units at a consistent speed.
Cut-off Unit
Cuts the continuous profile into specified lengths using saws or knives.

Hollow Blow Molding Technology
Hollow blow molding is a manufacturing process used to produce hollow plastic parts by inflating a heated plastic tube (parison) inside a mold. This technology is widely used for producing bottles, containers, and industrial components.
Extrusion Blow Molding
The most common method where a parison is extruded vertically and captured by a split mold. Air is then blown into the parison to form the part.
Injection Blow Molding
A process where a preform is injection molded and then transferred to a blow mold where it is inflated to its final shape.
Stretch Blow Molding
Similar to injection blow molding but includes a stretching rod to improve strength and clarity of the final product.
Multi-Layer Blow Molding
Combines two or more different plastics in a single part to achieve specific properties such as barrier resistance or structural integrity.
