During fabrication, melted plastic is injected into a stainless-steel mold to take on the required shape. The mold is outfitted with various customized cavities to form the product. When the melted plastic has been injected, the material begins filling out the cavities and the rest of the mold. The products are left to cool and are later ejected by pins.

Benefits of Injection Molding

Organizations requiring intricate products or high-volume runs often turn to plastic injection molding because the process makes it simple to achieve high levels of production while keeping the overall costs quite low. Once production begins, the cost per parts drops significantly. This process is also considered to be the most versatile of the molding processes currently available. It makes it easy to create products of all shapes, styles and sizes. If a project requires high degrees of customization, it’s relatively simple to change a number of factors concerning production. Manufacturers use a variety of plastic resins, additives, and finishes to make customization simple.

Other benefits of injection molding include:

• High level of versatility and customization
• Low production costs
• Efficient and reliable processes
• Strong and durable end products
