The Basic Knowledge Um Plastic Extrusion Machine

A brief introduction to plastic extruders to help you get a basic understanding of the machine

Table of Contents

What is plastic extrusion machine?

Plastic extrusion is a high-volume manufacturing technique in which raw plastic, typically in pellet form, is melted and extruded into a continuous profile. The process initiates as the resin is loaded into the extruder’s hopper and moves down into the barrel, where it is progressively heated until it melts. Following this, a screw mechanism drives the molten plastic through a die, which molds it into the required shape. As it cools and solidifies, it assumes the final form of various products, ranging from pipes and plastic sheeting for weather-stripping to wire insulation. This method is highly valued across various industries for its efficiency, versatility, and consistent ability to produce large volumes.

Working principle of plastic extruder

The Role of Extruders in Plastic Extrusion

Extruders serve as the core component in the plastic extrusion process, consisting primarily of a heated barrel outfitted with a rotating screw. The process begins with the introduction of raw plastic materials, typically in pellet form, into the extruder via a hopper. As the screw rotates, it drives the pellets forward into the barrel, where they encounter significant heat and pressure, causing them to melt into a viscous fluid. This fluid plastic is then extruded through a die—a tool engineered to mold the plastic into the specified profile as it emerges from the machine. The plastic product is subsequently cooled and solidified, retaining its shape as it is segmented into predetermined lengths. This method is crucial for producing continuous lengths of plastic in diverse shapes, thereby playing a pivotal role in various industrial applications.

Components of a Plastic Extrusion Machine


A standard Plastic Extrusion Machine is composed of several key components, each playing a crucial role in the extrusion process:

1. Hopper: The initial entry point for the raw plastic material, generally in pellet form. The hopper channels the material into the extruder’s barrel.
2. Barrel: This component encases the extruder screw and is fitted with heaters to melt the plastic. It is constructed to endure high pressures and temperatures.
3. Extruder Screw: A critical component that transports the plastic pellets from the hopper to the barrel’s far end. Its rotation not only moves the pellets but also generates the heat needed to melt them through friction.
4. Heaters: Positioned along the barrel, these elements assist the screw in melting the plastic and maintain the required temperature for successful extrusion.
5. Die: This custom-designed part shapes the molten plastic. It is tailored specifically to match the product’s desired profile.
6. Cooling System: Post-extrusion, the shaped plastic must be cooled and solidified. This system can include elements like fans, water baths, or cooling rollers.
7. Cutter: This tool segments the newly formed plastic into desired lengths and can range from a simple guillotine to a more intricate rotary cutter, depending on the product specifications.

Plastic Extrusion Machine Operating

The operation of a plastic extruder involves a systematic procedure to ensure efficient production of plastic products. The first step is to load the plastic pellets into the hopper, set the temperature control of the machine, and switch on the heater. The plastic is melted in the barrel and pushed towards the die head by the extruder screw. It is vital to ensure that the temperature and speed of the extruder screw are set correctly to achieve the desired quality of the end product. Once the molten plastic has passed through the die, it takes the desired shape. It is then cooled and solidified in a cooling system before being cut into specified lengths by a cutting machine. It is important to note that the smooth operation of a plastic extruder requires constant monitoring and timely adjustments to maintain optimum output and quality.

Downstream equipment in plastic extrusion

Downstream equipment in plastic extrusion pertains to the array of machinery deployed post-extrusion to apply final modifications to the product. This equipment performs various crucial functions such as cooling, cutting, pulling, and winding to enhance the final attributes of the extruded plastic. Key types of downstream equipment include:

Cooling Tanks: These units are essential for cooling the extruded plastic to solidify and stabilize its shape. The cooling medium—either chilled water or air—is selected based on the plastic type and the specifications of the final product.

cooling water sink

Pullers: These mechanisms ensure the extruded plastic maintains consistent speed and tension, critical for achieving uniform shape and size throughout the product. Available in various forms, such as belt pullers and roller pullers, they cater to different extrusion needs.

Cutters: After the cooling phase, cutters are employed to trim the extruded product to required lengths, ensuring precision in final measurements.

Traction & cutting machine

Coilers or Winders: For products such as tubes or profiles, coilers or winders collect the output on spools or reels, facilitating easier handling and transport.

Screen Printers: For products that need printed details or branding, screen printers are utilized to apply designs directly onto the surface of the extruded plastic.

The selection of downstream equipment is tailored to the specific type of product, material properties, and production demands. This equipment is integral to the extrusion process, playing a pivotal role in ensuring that the final product adheres to the set quality standards and meets precise specifications.

Considerations when choosing a machine

Productivity: High-capacity machines produce more product in less time, resulting in lower unit costs and a higher return on investment.
Energy Consumption: Machines with low energy consumption can significantly reduce operating costs and increase ROI.
Maintenance costs: Frequent maintenance can lead to increased costs and production downtime. Therefore, machines that require less maintenance can improve ROI.
Versatility: Machines that can process a wide range of plastic materials can meet a variety of production needs, increasing profitability.
Lifespan: The longer a machine’s lifespan, the higher the return on investment, as the initial investment can be spread over more production units.
Resale value: If the machine maintains a high resale value, the return on investment will increase.

Type of straw extrusion machine

In terms of material: there are pp straw extrusion machine, PLA straw extrusion machine, PHA straw extrusion machine,

In terms of main screw diameter: 50 mm and 65 mm main screws are available for the production of different diameter ranges of straw.

In terms of straw colour: single colour, two colour, two colour co-extrusion, three colour and three colour co-extrusion straw extrusion machine

Extruded pipe diameter adjustment

To precisely adjust the diameter of a pipe produced by an extrusion machine, various factors and settings must be meticulously managed and optimized:

1. Die and Calibrator Settings:
Confirm that the calibrator is correctly aligned and sized, usually 3-5% larger than the target pipe diameter.
Modify the die gap to suit the required pipe diameter. Increasing the gap enlarges the diameter, whereas reducing the gap decreases it.

2. Pressure Fluctuations:
Unstable compressed air can lead to uneven wall thickness in the pipe. This suggests that fluctuations in internal air pressure can cause variations in the pipe’s diameter or wall thickness

3. Extruder Throughput and Temperature:
Alter the extruder throughput—decreasing it will reduce the pipe diameter, while increasing it will enlarge the diameter.
Optimize the temperature settings of the extruder to ensure a consistent melt flow and prevent complications such as pipe sagging that can alter the diameter.

4. Traction Speed:
Modify the haul-off unit’s speed. Accelerating the traction speed decreases the pipe diameter, while slowing it increases the diameter.

5. Cooling System:
Adjust the cooling system, specifically the water flow and temperature in the cooling tanks, to guarantee even cooling. Non-uniform cooling can cause fluctuations in the pipe diameter.

6. Tooling and Sizing Equipment:
Choose appropriate tooling for the specified pipe dimensions and ensure it is well-maintained and accurately calibrated.

By meticulously managing these parameters, the diameter of the pipe from the extrusion machine can be effectively controlled and precisely adjusted to meet specific requirements.
