There are indeed many Rigid vinyl compound extrusion methods, such as vacuum forming, cold top (hard top) forming, co-extrusion and so on.

If high productivity is required, and there are no special requirements on the surface of the product, most of them choose vacuum forming (mold) to vacuum. If the product surface mirror effect or high filling profile and pipe extrusion are required, cold top (hard top) molding is generally selected, but the production efficiency of hard top molding is relatively low and the extrusion speed is relatively slow. The advantage is that the surface of the product is smooth and clean. High filling materials can be used.

Hard top molding is to directly use the shape of the mold, and the material is directly ejected from the screw die through the mold. Generally, the product is cooled by water after the mold is ejected. Vacuum forming generally has a certain stretch forming ratio from the die, so the material is required to be relatively tough and strong, and the addition of fillers is relatively small.
