A process used to develop products like refrigerator magnets and vehicle bumpers, plastisol casting is a cost-effective casting method that can vary based on the product being produced.
Open mold casting and slush casting (also known as slush molding) are the two plastisol casting methods we at Piper Plastics specialize in.
Since plastisol is primarily a suspension of PVC particles in a liquid plasticizer, it flows as a liquid and can be poured into a open mold.
Because of the open mold, this process is good for items with a “flat” bottom. Common examples include:
The second plastisol casting process that we specialize in is slush molding. A more complex casting option than open mold casting, slush molding is a cost-effective alternative to injection molding that can be used to develop some plastic products.
Metal molds are used when slush casting, as these molds are not affected by heat and can allow for a faster production time than flexible mold alternatives. Metal molds are able to be used over and over again, making them a major asset to the product manufacturer.
