A Brief Guide to Plastic Injection Molding 

It’s a Manufacturing Process

Plastic injection molding is one of the most common manufacturing processes in existence today. It’s used to create a wide range of commercial plastic products, such as toys, furniture, and computer monitors. These items are mass produced through the use of a mold, which is pumped with plastic pellets or resins. When the substance is heated, they melt and form a perfect replica of the mold. 

It Was Invented in the Late 1800s

In 1868, John Wesley Hyatt invented the plastic molding process to create pool balls by injecting celluloid into a mold, thus creating a fast and easy way to mass produce billiard balls. He later expanded upon this idea by creating an injection molding machine, in which an assembly machine used a plunger-like tool to pump plastics into molds. Several years later, inventor James Hendry created the screw-injection molding machine, and both are still in use today. 

Different Plastics Are Used for Different Products

When it comes to plastic injection molding, a wide variety of plastics can be used—it all depends on the product being created. Some of the more common plastics are polystyrene, polycarbonate, Teflon®, Delrin®, and acrylic. With these plastics, professionals can manufacture everything from cassette racks to centrifuge tubes.
