PVC-WPC Foam Sheet, Door, Door Frame, Louvers and Decorative Panel Production Line
PVC WPC foam board is a new material for both inside or outside decoration. It has a hard and smooth surface, which can be laminated by various materials such as PVC film, impregnated paper, etc. It opens a new world of decoration, the laminated board is not only waterproof, UV resistant and anti-corrosion, but also special and beautiful.
1. Twin screw extruder
Screw and Barrel material: high-quality alloy steel, short, half, and full skd or bimetallic as per consumer’s need.
Barrel cooling through the fan cooling and water cooing at the same time.OMRON temperature apparatus and PID type temperature fluctuation self controller.
Schneider AC contactor.
This unit is to melt the material and to pass to get the desired shape.
The screw inside the barrel rotates and conveys the PVC material forward while simultaneously heating and melting it. At Khushi and Tashi enterprise, we believe in delivering standard quality where we use Bohai made screw barrel, schneider siemens, ABB drive and vertical gear box.
2. Die head and calibration unit
The die head and calibration unit work in tandem to give shape to the molten plastic and facilitate the cooling process.
The die head’s chromium plating and polishing enhance the flow and formation of the foam board profile, while the calibration unit’s water chiller and stainless steel carrier rollers ensure precise and consistent cooling, resulting in foam boards with the desired properties and dimensions.
After extrusion, the still-molten PVC profile enters the calibration table or calibration unit. This stage is crucial for shaping the profile to meet precise dimensional specifications.
- The calibration table typically includes a series of vacuum or cooling tanks through which the extruded profile passes. These tanks are filled with water to rapidly cool and solidify the profile.
- The profile is shaped and dimensionally stabilized in these tanks using specially designed tools, vacuum, and water cooling.
3. Haul off
In foam board production, the roller haul-off machine is essential for maintaining the uniformity and quality of the foam boards. Its pneumatic pressing system, robust construction, and reliable transmission mechanism ensure the efficient handling of foam board materials, contributing to the production of high-quality foam boards with consistent properties. It has pneumatic pressing, larger diameter shaft heads and robust bearings with double-row chain drive.
- The haul-off unit, also known as a puller, is positioned after the calibration unit. Its primary function is to maintain constant tension and speed on the extruded profile as it passes through the calibration process.
- It consists of rubber or gripping rollers that engage with the profile and pull it through the calibration unit at a controlled rate.
- The puller ensures that the profile maintains the desired dimensions set in the calibration stage.
4. Cutter and Stacker
Longitudinal cutting machine:
The rubber brick compacting device will provide the accurate cutting precision when the cutter works, workstations and blade will be controlled to move up and down by the cylinder.
You can choose manually cutting and automatic cutting mode.
Transverse cutting machine(with dust collector):
The saw blade is a high-quality alloy steel, which adopts meter automatic control fixed length cutting with vacuuming device
The stacker unit in a foam board extrusion machine is responsible for receiving, stacking, and neatly organizing the extruded foam boards as they come out of the production line.
