what type of plastics can be injection molded
In Injection Molding, melted plastic is forced into a mold cavity. Once cooled, the mold can be removed. This plastic molding process is commonly used in mass-production or prototyping of a product. Injection molding machines were made in the 1930s. These can be used to mass produce toys, kitchen utensils, bottle caps, and cell phone stands to name a few.
