Basics of the Injection Molding Process
At its core, the injection molding process is a relatively simple one. Molten plastic is forced into a mold, often called a die or a tool, shaped like the desired finished product. The plastic cools in the mold, taking the shape of the product, and is ejected. The part is completed after minimal secondary processing.
Injection molding allows for the use of a large diversity of materials — plastic pellets can be premixed, or mixed directly into the hopper of a molding machine, to meet virtually any specification. The process can also produce parts of extremely complex geometries, which would be difficult, costly, or impossible to produce by other means.
Other benefits of injection molding include very high production rates, long tool lifespan, minimal tool maintenance, and excellent repeatability.
Injection molding is a versatile manufacturing process with a long history. From the time the first injection molding machine was patented in 1872 until the creation of the screw injection molding machine, a standard piece of molding equipment in the industry today, the injection molding industry has expanded tremendously by satisfying high volume, low-cost manufacturing requirements.
Originally used to manufacture relatively simple products, such as buttons and combs, the injection molding process has evolved considerably over the years. Decatur Mold has been a part of this history since 1966.
