WHERE IT’S MADE: Bedford, Ohio
HOW IT’S MADE: Injection molding is a manufacturing technique for creating various parts from thermoplastic polymer. Once a design is complete, a mold maker builds a mold from tool steel or aluminum to form the precise features of the desired part.
During the injection phase, polymer in the form of pellets is loaded into a hopper on top of the molding machine. The extreme pressure and friction generated by a reciprocating screw along with heaters in the barrel produce the heat to melt the pellets.
The two halves of the mold close and are clamped together. Next the melted polymer is forced under extreme pressure into the mold cavity. It is then allowed to cool and solidify into the shape of the mold creating the newly designed part.
The clamping unit opens which separates the two halves of the mold and an ejecting rod and plate expel the finished part from the mold. The process then repeats at cycles of 20 – 90 seconds on average.
HOW IT’S USED: Injection molded parts are light weight and cost-effective to mass produce. It is the most common method of part production used today. Various parts from the smallest component to huge automotive parts are created using this process.
