PVC Foam Board Sheet Making Machine


The PVC foam board, otherwise known as Chevron board or Andy board is widely used for both indoor and outdoor applications. It comprises the chemical composition, Poly Vinyl Chloride, which is used in furniture, building, and advertising industries.

It has two main parts:

· Hot Tank (top)

· The hot tank has a stainless steel blade and a heater.

· Remember, the raw materials may have some moisture that you should remove before proceeding with the processing.

· Heat required to drive away moisture is generated by the heater and friction due to the blade’s high-speed impact on the powder.

· Cooling Tank (bottom)

· While heating is necessary to dry the materials, it may cause decomposition and plasticization.

· We don’t want this to happen in the mixer. Only in the extruder. Thus, we quickly discharge the hot raw materials into the cooling tank.

· It has a cold water inlet and hot water output. It also has a low-speed stirrer.

· After cooling the raw materials to about 45℃, the material is discharged from the cooling tank into the screw loader, which we will talk about next:

2.Screw loader

It has a capacity of 200 Kilograms. It is also fitted with a timing device.

Now the screw loader must convey the raw materials to the feed hopper, which is part of the extruder. For this purpose, it has a rotating helical screw that scoops the material and convey it upwards before it’s released in the conical shaped feed hopper.

From the hopper, the raw material descends onto the rotating screws by double screw gravity. Our screw loader allows you to set the wait time and loading time. This allows the screw loader to operate autonomously. It is a great feature because; you don’t have to hire extra hands to load the raw materials manually. Thus, you save your labor and money. We also made it using stainless steel instead of aluminum to give it extended service life.

3. Conical twin screw extruder

Extrusion is the most critical step in manufacturing PVC foam board.

It entails heating and plasticizing the PVC resin and Other raw materials to form a molten plastic polymer that flows freely.

We used a twin screw conical extruder for our line. While it may sound like a complicated machine, it very easy to understand.

First, it has two rotating screws in the barrel. They rotate in opposite directions to convey the plastic material forward and plasticize the material.

Cast aluminum heaters placed under the barrel provide high temperatures required to melt the PVC resin and other additives.

More heat is generated by friction as the screws convey the materials through the extruder.

You also need to know is that temperature control is very essential. High temperatures can cause PVC resin raw materials to deteriorate.

And low temperatures would lead to the uncompleted process.

For monitoring of the temperatures, LANGBO MACHINERY has included the Ormon temperature controller that’s controlled on the electrical cabinet.

If temperatures go above what is required, cooling fans lining the barrel can be active. Our machine is set to issue a warning if the temperatures are abnormal.

4. T-die

In non-foaming plastic manufacturing like for the plastic pvc profile, wpc decking board, the t-shaping die gives the extrudate its flat, final shape.

But in the foaming process, the t-die stops the foam from expanding. And gives it a general shape that will be later perfected by in calibration table.

Also note that, after the sheet leaves the die it will expand as bubbles foam in its internal structure.

This expansion is controlled by the molds ensuring you get the desired final shape and the right thickness.

5. Calibration table

When the extrudate leaves the shaping die, it enters into the calibration table. So, it’s mounted next to the t-shaping die.

But, what is it? It is table that holds equipment required for foaming and cooling.

In the case of our PVC foaming machine, that equipment is the foaming molds and cooling bracket.

Let’s discuss them in full:

6. Group forming molds

Molds are shaped like the final board. Their inside surface is made of stainless steel for durability.

It is polished to provide the least amount of resistance to plastic foam board’s movement.
