The Plastic Mold Manufacturing Process
The injection molding process starts with plastic resin pellets. The resin is heated to a molten state and then shot into mold. The plastic pellets are loaded into a hopper that is used to supply the injection-molding machine. The pellets are gravity-fed from the hopper into a heated chamber called the barrel where they are melted, compressed, and injected into the mold’s runner system by a reciprocating screw. A runner refers to the channel in the mold used to deliver the molten plastic to the mold cavity.
The granules are slowly moved forward by a screw-type plunger and the melted plastic is forced through a nozzle that connects to the mold sprue bushing, that controls the flow of material, allowing it to enter the mold cavity through a gate and runner system.
The metal mold is kept at a lower temperature so the plastic will solidify almost as soon as the mold is filled. The part cools and hardens to the shape of the mold cavity. The two halves of the mold, Side A and Side B, or the Cavity and the Core, open up and ejector pins push the part out of the mold where it falls into a bin. The mold is then closed and the process begins again.
Injection Molding Plastic
Plastic injection molding is widely used because it can be adapted to meet almost any requirement, depending on the type of plastic being molded. Choosing the correct plastic is an important decision. Available plastics have a variety of characteristics based on their chemical make up. The intended application of the part will also determine the type of plastic that can be used. Material properties to consider include durability, flexibility, performance, texture, density, and color. Contact the experts at ICOMold for help choosing the right plastic for your next project. ICOMold keeps over 300 different plastics in stock for injection molding including:

Cost of Plastic Injection Molding
The cost of plastic injection molding is dependent on several variables, including part complexity, chosen material, and the number of parts being produced. The largest expense will be in creating the mold. Simple molds can cost $3,000 to $6,000 while more complex molds will cost $25,000 to $50,000. The next variable will be the number of parts being produced. The more parts being injection molded, the less each part will cost. Each individual part can cost a few pennies to over $10 a piece. The final cost of each piece will depend on the type of plastic being used, the overall cost of the mold, and the number of parts being produced. The up-front cost for plastic injection molding can be higher than other manufacturing methods, however, the savings can be substantial considering that each piece, when manufactured in the hundreds, thousands, or millions could only cost pennies per part.
What are the Disadvantages of Injection Molding?
Injection molding is a manufacturing process designed to make hundreds, thousands, or even millions of the same part or set of parts. It is an efficient and economical way for small or large businesses alike, to mass-produce plastic parts. The only real disadvantage can be the cost of each piece when making a small number of parts. WAHI has access to a wide range of manufacturing processes that can be utilized to manufacture prototype or low-number part runs.
