ABS - Injection Moulding

Plastic Injection Moulding

Plastic injection moulding is extremely common throughout the world because it gives the fastest results at the best cost. Put simply, the reliability and efficiency provided by the plastic injection moulding process have not been matched.

  • Efficient & Quick production cycles
  • Complex Designs
  • Superior Strength
  • Enhanced Flexibility
  • Low Waste
  • Low Cost
LSR - Injection Moulding

Liquid Silicone Moulding

Liquid Silicone Rubber, LSR, is an injection moulding process for thermosetting polymers. This process is used in several industries because of the superior properties of the produced parts. The process of LSR injection moulding is extremely similar to plastic injection moulding and the main difference is in the tooling process which is simpler.

  • Chemical Resistance
  • Temperature Resistance
  • Superior Mechanical & Electric Properties
  • Bio-compatibility

Injection Moulding Mould Material Comparison

Aluminium vs Steel

Tooling Cost

Aluminium offers a clear advantage over steel in terms of lower pricing, but the overall value and return on investment of an aluminium mould and a steel mould can vary greatly, based on the usage of the mould.

Cost per part

This factor depends on the intended production run, and the overall lifespan that the customer hopes to get out of their part. For shorter runs, the lower upfront costs of aluminium moulds can lead to lower overall cost per part. If the customer intends to use their mould for high volumes in the millions and tens of millions of parts, they’ll see the investment in a steel mould pay off.

Heating and Cooling times

Aluminium moulds has a much higher rate of heat dissipation and can heat and cool much more quickly than steel moulds — typically up to seven times. Cooling time, especially, makes up a significant portion of overall cycle time in injection moulding.

Shrink, warp and other defects

Aluminium means the mould is better able to approach uniform heating and cooling times — and to do so more quickly — which provides an advantage in decreasing the number of defective and rejected parts. Non-uniform heating and cooling are among the biggest factors in defects such as sink marks, voids and burn marks.

Ease of modification and repair

Damaged or deformed steel moulds can be really difficult and costly to repair, due to the extreme hardness of the material. All too often, a new mould will be required in such cases. Aluminium moulds are much more receptive to repair and, as a softer material, can be more easily modified in cases where production errors may have occurred.

Detailed features

When extremely fine, detailed features are required — e.g., thin, non-uniform walls, less rounded angles and tighter, narrower areas of the mould cavity — steel moulds will often provide better results than aluminium.

Common Mould Materials

P20 Steel

28-30 RC hardness. P-20 is the first choice in most cases when using plastics without abrasive additives, but unless it’s for very low-volume use, it needs to be protected erosion with a coating or surface hardening.

NAK80 Steel

Tougher than P20, while also machining much faster. It holds tight tolerances and more corrosion resistant. A potential disadvantage is that it has poorer heat transference, so it needs to be cooled more carefully.

S-7 Steel

Used for very tight-tolerance and high-volume parts. It’s a very durable, impact-resistant tool steel that can be hardened up to 56 RC.

H13 Steel

A Typically the go-to choice for a tool steel to address wear when running abrasive materials. In most cases, cavities are not hardened above 50 RC to reduce the chances of stress cracks. The typical range is 44-48 RC.

S-316 Steel

It’s the most corrosion resistant when injecting PVC or POM plastics but it has one of lowest thermal efficiency.

7000 series Aluminium

A high-strength aluminium alloy with a relatively large percentage of zinc. It has the best heat transfer properties of common tool metals, but it is not suitable for injecting corrosive resins like POM or PVC, or those with glass fibres added to them, as glass fibres will erode the mould surfaces.

Mould Lifetime

Any injection mould will be subject to wear. Wear will occur particularly to ejectors, gates, slides & other moving parts of the tool. Surface finishes such as high polish or sparked finish will also become less defined over time.

Mould Material

Soft aluminium moulds will incur much more wear from the plastic material than hard steel moulds. Steel moulds should last for millions of mouldings.

Moulding Material

Certain materials can be very abrasive, such as glass filled nylon for example. Other materials are very corrosive and will rust normal steel moulds, so aluminium alloy or stainless-steel moulds should be used, or the steel mould should be stainless steel or aluminium alloy plated.

Mould setter skill

Moulds need to be set up to work in the injection moulding machine correctly. Overclocking, poor tool alignment, excessive ejector stroke, over pressurisation of the plastic material, not enough lubricant on the ejectors are all examples of poor setting which wear any mould down much more quickly than necessary.


Thermoplastic injection moulding is the most common way to manufacture parts. Thermoplastics are polymers that can be repeatedly molten or softened by heating and solidified by cooling.
