Most Common Materials Used by Tip Top Plastics in Plastic Injection Moulding

21 November 2022

When it comes to producing parts and products, manufacturers would often opt for materials that can ensure their effectiveness and longevity. One material that they take advantage of is plastic since it is generally durable, resistant to elements, and versatile. It can even be moulded into various form factors and shapes.

To effectively manufacture plastic parts and products, most manufacturers are expected to carry out plastic injection moulding. Plastic injection moulding is a manufacturing process wherein the molten plastic material is injected into a customised mould. The molten material will then cool down and solidify to its final form. Complex parts and products can be generated by this process as the mould can be modified into various shapes and styles.

At Tip Top Plastics, we have been maximising this process in producing plastic parts and products since it can produce large volumes of plastic parts and products consistently and efficiently. Here are some plastic materials that we process with plastic injection moulding.

Acrylonitrile Butadiene Styrene (ABS)

Acrylonitrile butadiene styrene or ABS is a plastic material popular for its transparent look. It has a relatively low melting point, making this material easier to mould and process. One great quality of ABS is it can boast various textures and surface finishes. It is also strong and resistant to impact, heat, oils, acids, and alkalis. This material, however, can be weak against weather elements. All these properties make ABS a good material for electrical components, plastic wall plates for outlets, automotive components, and industrial fittings.

Polystyrene (PS)

Polystyrene is a plastic that can be classified into two, namely, general-purpose polystyrene and high-impact polystyrene. The general purpose of polystyrene is known for its brittleness and glass-like clarity. It has, however, less dimensional stability compared to its high-impact counterpart. The high-impact one, on the other hand, is opaque and has better dimensional stability. Both types, fortunately, can be processed with plastic injection moulding as they can produce lightweight and durable parts and products.

Polyvinyl Chloride (PVC)

Polyvinyl chloride or PVC is popular in a wide array of industries due to its versatility. This material is softer and more malleable, making it great for food packaging materials, textiles, and advertising vinyl signs. As for the more rigid version of this material, it can be processed into water pipes, drink bottles, and children’s toys. Most of these products are expected to be lightweight, strong, cost-effective, and recyclable.

Polypropylene (PP)

Polypropylene is a flexible polymer known for its strong resistance to heat, chemicals, solvents, and acids. It also maximises a low-friction surface and hygienic finish. These qualities make this plastic great for producing plastic films for packaging and labelling, carpets, washing up bowls, microwavable dishes, sporting goods, and storage containers. Upon the end of their service life, polypropylene products can be collected and recycled up to four times.

Polycarbonate (PC)

Polycarbonate has great strength and toughness that makes this material one of the most utilised plastics in the manufacturing industry. Even at various temperatures, this material can easily maintain its physical properties and colour for a long time. PC, however, is not recommended for food-related products. This material can be used for windows, light pipes for LEDs, and machinery guards.
