What are the difficulties in PVC mold process?

PVC, the key component is polyethylene, and other ingredients are added to improve its temperature resistance, ductility, plasticity, etc. The top of such surface facial mask is paint, the main component in the middle is polyethylene, and the bottom layer is back coating adhesive. It is a composite material that is highly favored, popular, and widely used by PVC mold manufacturers in today's society.

PVC is the basic raw material for PVC mold manufacturers, and PVC mold manufacturers add tackifiers, foam adhesives, and other modifiers. After pre molding, mixing, pulling and punching. Finally, it was completed using a press mold running method.

Because the air blowing inspection slipper is a new type of slipper made from PVC raw materials, which is very sensitive to production and processing temperature, and is very prone to burning during the production process. In addition, this new type of shoe material adds various new chemical plant modifiers during the processing, so it has higher production and manufacturing regulations and technological content compared to traditional slippers, The grinding tools and processing technology differ greatly from the standards set by traditional cold mops, and many manufacturers face the following difficulties in the processing process:

The raw materials are very easy to fade in the coking plant, the production temperature is low, and polyurethane foaming is not good, and the product is too heavy; The production and manufacturing temperature is too high, and the raw materials are prone to burning, discoloration, and surface foaming.

The foam of polyurethane foam is uneven, with loose holes in the front, back, left, and right sides, and poor foam in the middle, resulting in insufficient load-bearing capacity.

The surface color tone is uneven, with severe color deviation in the front, back, left, right, and center, and severe air marks around the injection hole.
