Plastic injection moulding is a versatile and cost-effective manufacturing process that produces a wide range of products, from everyday household items to complex industrial components.  

But – the success of this process largely depends on selecting the right plastic material for the job. 

Read on as we take a closer look at some of the most commonly used plastics in injection moulding. 

Types of Plastics Used in Injection Moulding 

So, what are the core types of plastic used in injection moulding? Here are five of the most popular options: 

  1. Polypropylene (PP): A popular choice for plastic injection moulding due to its excellent chemical resistance, high strength-to-weight ratio, and good fatigue resistance. It’s commonly used to produce children’s toys, household appliances, and packaging materials. 
  1. Acrylonitrile Butadiene Styrene (ABS): ABS is known for its high impact resistance, dimensional stability, and ease of processing. It’s often used to produce toys, electronic housings, and automotive interior components. 
  1. High-Density Polyethylene (HDPE): HDPE is a tough, durable, and chemically resistant plastic that is commonly used in the production of crates, containers, and pipes. Its excellent moisture barrier properties make it suitable for packaging applications. 
  1. Nylon (PA): Nylon or polyamide (PA) comes in many different grades suitable for a range of applications. Typically, it is selected for its chemical resistance, strength and flexibility. At BEC nylon is used to produce filters for the automotive industry. Both the mesh and plastic frame of such filters are made from nylon to ensure they withstand the tough environments they work in. 
  1. Acetal (POM): Acetal, also known as polyoxymethylene (POM), is a high-performance engineering plastic that offers excellent dimensional stability, low friction, and high resistance to wear and chemicals. It’s commonly used to produce gears, bearings, and other mechanical components. 

Factors to Consider When Choosing a Plastic for Injection Moulding 

When selecting a plastic for your injection moulding project, there are several factors to consider: 

  • Mechanical properties: Consider the strength, stiffness, and impact resistance required for your application. 
  • Chemical resistance: Evaluate the plastic’s ability to withstand exposure to chemicals, solvents, and other substances. 
  • Temperature resistance: Determine the temperature range in which the plastic must maintain its properties. 
  • Aesthetics: Consider your product’s desired appearance, colour, and surface finish. 
  • Cost: Evaluate the cost of the plastic material in your project’s budget and production volume.
