WPC Profile Extrusion Line - PE/PP/PS/TPE/PVC

The WPC profile extrusion line is a set of machines used in the production of WPC boards.

Differences between WPC profile extrusion and general profile extrusion

WPC profile extrusion machine is different from general profile extrusion machine, It has to maximize mixing while minimizing damage to the biomass furnish because the WPC material involves two different types of materials: wood and plastic. It is more accurate processing temperature, melt flow index, etc. are required. The same is that general profile extrusion is a process by which various plastic materials are used to develop quality plastic products that have a feature of continuous (ex: plastic board) but do not include sheet or film products.

How does WPC profile extrusion line work?

The process of WPC profile extrusion begins with the mixing of wood powder and plastic in the mixer. The ratio of wood powder to plastic varies depending on the desired strength and durability of the final product. Once the mixture is blended, it is fed into the conical twin-screw extruder. The extruder has two screws that rotate in opposite directions, pushing the mixture through a barrel and melting it.

The molten mixture is then pushed through a die that determines the shape and size of the extruded profile. The extruded profile is then passed through the vacuum calibration table, which cools it and sets its shape. The haul-off machine pulls the profile through the calibration table, maintaining its shape and ensuring its dimensions are correct. The cutting machine cuts the profile to the desired length, and the stacker stacks the finished product.

Advantages of WPC profile extrusion line

• Efficient and consistent production of high-quality WPC profile products.
• The extrusion process ensures that the final product has a uniform shape and size, with consistent mechanical properties.
• Highly automated, reducing the risk of human error and increasing efficiency.
