What Is Injection Molding?
High-Volume Plastic Production via Injection MoldingWhen you need thousands of identical plastic parts, injection molding is the most cost-efficient manufacturing process.Molten plastic is injected at high pressure into a steel mold tool. After curing, the molded part is ejected. This cycle repeats rapidly to produce hundreds or thousands of parts.Amortizing the mold cost over high volumes results in a very low per-unit price, often just a few dollars. Automation also ensures extremely fast cycle times.
Compared to other processes like CNC or 3D printing, injection molding offers vastly more material options like engineering-grade thermoplastics. Cosmetic choices like colors, textures, and coatings are also abundant.

How Custom Plastic Injection Molding Works
How to do plastic injection molding
Plastic injection molding manufactures parts by melting and injecting thermoplastic or thermoset polymers into dedicated molds. The raw plastic materials, in the form of pellets or granules, are fed into the injection molding machine’s heating barrel. This melts the resin using heat and shear forces. The now viscous molten plastic is then injected under high pressures into a steel or aluminum mold tool. The mold cavities are shaped to produce the desired part geometry.As the plastic cools inside the mold, it solidifies into the final plastic part shape. Sophisticated process controls precisely regulate injection pressures, packing, cooling times, and mold temperatures to optimize quality and cycle times.
Rigid Plastic Materials:
High-strength general-purpose engineering plastic, used for many commercial products.

A tough and rigid material resistant to lubricants, solvents, and cleaning agents. Very common in electronic enclosures.
A blend of PC and PET provides tough and chemically resistant results and can be used as an alternate to PC-ABS. It endures harsh solvents and cleaners, making it excellent for sports equipment and healthcare applications.
A thermoplastic polyester that typically outperforms PET due to lower moisture absorption and better environmental stability. PCT is often used for connectors and switches.
One of the most common plastics used in the world, PE has high ductility, abrasion resistance, and chemical resistance. PE is often described by its molecular weight, such as UHMW PE (ultra-high molecular weight), LDPE (low density), or HDPE (high density). PE is used in packaging, tubing, films, bottles, and more.
Offering excellent tensile strength that surpasses most plastics, PEEK is often used as a lightweight substitute for metal parts in high-temperature, high-stress applications. PEEK resists chemicals, wear, and moisture.

A biodegradable and renewable plastic. PLA has a relatively low glass transition temperature and is common in short-use applications.
A clear glass-like plastic. Good wear and tear properties. Great for outdoor use.
Good moisture resistance, high wear-resistance, and low friction.
Polypropylene has excellent electrical properties and little or no moisture absorption. It carries light loads for a long period in varying temperatures. It can be molded into parts requiring chemical or corrosion resistance.
A subset of nylons (polyamide) that typically exhibit a higher melting point and lower moisture absorption. PPA is typically used in automotive and industrial applications because it can withstand harsh chemicals. PPA is good for fuel and fluid manifolds and headlight housings.
