What plastics are commonly used in mass production?

Introduction

When your product is ready to move from prototype to small batches of hundreds or thousands of pieces, or even larger production runs, injection molding is the primary production method. Choosing the right plastic material is a critical first step in ensuring your product’s performance, appearance, and cost meet your expectations. The following introduces several of the most commonly used plastic materials in mass production.

General-Purpose Plastics

These plastics offer high production volumes, a wide range of applications, and low cost, meeting the needs of most everyday products.

  • ABS (Acrylonitrile-Butadiene-Styrene): This is one of the most popular general-purpose engineering plastics, offering an excellent balance of strength, toughness, and surface gloss. It is highly amenable to post-processing, suitable for surface treatments like painting and plating, and is widely used in a variety of electronic product housings, home appliances, toys, and more.
  • PP (Polypropylene): PP is characterized by its excellent chemical resistance, high toughness, and resistance to flexural fatigue. It is often used in hinges that require repeated opening and closing, such as bottle caps. It is also a common food-grade material used in tableware, containers, and more.

  • PE (Polyethylene): Similar to PP, PE offers excellent chemical resistance and toughness at a lower cost. It is the world’s most produced plastic. It is commonly found in products such as bottles, plastic bags, and pipes.

Engineering Plastics

Compared to general-purpose plastics, engineering plastics offer superior mechanical strength, temperature resistance, and abrasion resistance, making them suitable for industrial and structural applications with demanding performance requirements.

  • PC (Polycarbonate): PC is best known for its exceptional impact resistance (commonly known as bulletproof plastic) and high transparency. It is extremely strong and can withstand high temperatures, making it a popular choice for transparent face masks, lampshades, and electronic device casings requiring high strength.

  • PA (Nylon): Nylon (also known as polyamide) is known for its excellent wear resistance, high toughness, and high strength. It is an ideal choice for wear-resistant moving parts such as gears, bearings, and sliders.
  • POM (Polyoxymethylene): POM offers high hardness, high rigidity, excellent wear resistance, a very low coefficient of friction, and excellent dimensional stability. It is often used to replace metal in precision gears, bearings, and transmission components.
  • PMMA (Acrylic): PMMA’s greatest strengths are its exceptional transparency and gloss, comparable to glass, and its excellent weather resistance. It is primarily used in applications requiring high optical quality, such as instrument panels, lenses, and delicate cosmetic cases.

Conclusion

From low-cost general-purpose plastics to high-performance engineering plastics, each material has unique properties and applications. When planning mass production, selecting the most appropriate plastic material based on your product’s specific application—whether it requires an impact-resistant housing (PC), wear-resistant gears (PA/POM), or a clip that requires repeated bending (PP)—is the first step to successful development.
