The Plastic Injection Molding Process
Plastic injection molding is the process of filling a mold tool with liquid plastic resin under great pressure. The tool may comprise a single cavity or hundreds of cavities in order to make indefinite numbers of parts. Once the mold tools have been carefully designed and manufactured, the molding process consists of the following basic steps:
● Step 1 – The plastic resin comes in raw pellets. These are dried to the right moisture content, and then if necessary they can be blended with pigments or master batch colorants to create the correct color for the design.
● Step 2 – The dried pellets are poured into the hopper of the molding machine. A reciprocating screw inside the barrel of the machine is used to transport these pellets towards the mold while at the same time heating them.
● Step 3 – Within the barrel, the pellets are mixed and heated until fully molten, forming the liquid resin.
● Step 4 – The heated mold closes automatically and resin, under great pressure, is injected through a gate and into the mold cavity.
● Step 5 – The mold is cooled in a short amount of time to solidify the part inside.
● Step 6 – The mold opens and the part is ejected to begin a new cycle.
Advantages Of Plastic Injection Molding
There are many advantages to plastic injection molding. These include the ability to make large volumes of parts quickly, high surface quality, many resins to choose from, color flexibility, and durable tooling that can last for years.

Applications for Plastic Injection Molding
Plastic Injection in the Medical Industry
Plastic is very useful in the medical field. Resins are lightweight, non-toxic, inexpensive and can be reused or recycled. Applications include syringes, catheters, dispensers, tubing, and other appliances. For more information about plastic injection molding in the medical field, read our blog post.
Plastic Injection in Consumer Products
We use plastic every day for work and play. Plastic compounds with different chemical properties are found in computer keyboards and mice, game controllers, headphones, toys, home appliances and kitchen gadgets – anywhere you look. Learn more about plastic used for consumer products.
Plastic Injection in the Electronics Industry
Components like circuit boards, switches, wires, batteries, and sensors must be placed in strong, lightweight, non-corrosive, and non-conductive housings to protect them while also safeguarding the user. Learn why plastic injection molding is an ideal solution to support the electronics industry.
Plastic Injection in the Agriculture Industry
Plastic products used in agriculture must be strong and durable, able to resist UV light and chemicals. Engineered plastic parts are used in conveyor belts, drive trains, feeders, water sprinklers, fencing, tools, and much more. Learn why plastic injection is a great solution for the agriculture industry.
Plastic Injection Molding Tolerances
Plastic resins expand and contract because of temperature, mechanical stress and moisture. Our manufacturing tolerance guide gives you general information on the shrinkage characteristics of most common resin types to help guide your design decisions.
As part of our design analysis, we’ll indicate any areas that might produce thermal stress, shrinkage, warping, or other avoidable defects in your injection molded parts. For more information, consult our manufacturing design guide on common defects and how to avoid them.
