What's the production process of plastic extrusion line?

Raw material mixing: The automatic feeding and mixing system can accurately complete the feeding, weighing, and mixing processes, which replaces the traditional manual feeding and improves accuracy. After mixing, the materials can be added to the hopper of the extruder after they are cooled to a certain temperature. Extrusion of plastic pipe products: The screw rotates in the barrel, and the mixture is plasticized and pushed to the machine head. After compacting, melting, mixing and other procedures, the purpose of exhausting dehydration is realized, and then it is extruded through the die forming. Vacuum shaping: the vacuum shaping water tank is used for pipe shaping and cooling. Traction: Continuously and automatically haul out the shaped and cooled pipe. Cutting: According to the length set in advance, it can realize automatic fixed-length cutting. 6. Rewinding or stacker: equipped with automatic unloading device, greatly reducing manual labor.

What is an extrusion line?

A sheet extrusion line consists of an Extruder (single or twin screw), equipped with a Screen Changer and a Gear Pump, followed by a Static Mixer (sometimes feeding a Coextrusion Feedblock that is preceded by one or more additional extruders sets as described above), feeding a flat sheet die.

What is plastic extrusion?

Plastic extrusion is a continuous process in which solid plastic pellets or powder are melted into an homogeneous mass through a combination of applied heat and friction heat generated by the extrusion screw or screws transporting the material through a barrel. The mass or polymer melt is pushed through an extrusion die to produce a shape, tube or sheet. The extrudate is then cooled by various means into its final form and cut to length using various cut-off devices.

What is extrusion tooling?

Extrusion tooling costs of a die, downstream calibration, and fabrication equipment. Molten plastic enters the die at an enlarged opening that gradually narrows (much like a funnel) as the plastic nears the exit point of the die. Next, the plastic passes through a series of sizes that hold the plastic in shape until it has cooled. The shape is cut to length with a cutter or saw. Fabrication equipment, including punches or embossing rolls, can be used during this process to finish the product.

What Is Your Standard Stock Extrusion Length?

Most stock extrusions are available in 96' lengths but we will also cut to size.

Are you trading company?

No. We are a factory, we are the source.

What is the Meaning of Auxiliary Equipment？

Plastic auxiliary equipment covers a wide range, from batch raw material processing and storage to mixing and metering, to the drying, packaging, storage and transportation of finished products. Pipes line auxiliary machine is related to the operating efficiency and safety of the entire mixing plant. Auxiliary machine for pipe line is critical to the final quality of the customer's plant. And return.

Auxiliary Equipment for Plastic Processing

Plastic auxiliary equipment can be used as an indispensable part of the extrusion process to improve or optimize the efficiency of the extrusion process and simplify the operation. In the plastics processing industry, such as extrusion, the required components are the host that meets the requirements. On the contrary, the essential components are several plastic auxiliary equipment to complete all the processes. Therefore, product quality and corporate profitability depend on the automation and rationalization of plastic auxiliary machine.
