Acetal materials are hard and tough, and also resilient and offering high impact resistance at different temperatures, including very low ones.

Out of these materials, homopolymers are characterised by the highest strength, and copolymers offer high thermal stability.

Acetal Injection Moulding

These properties are taken into consideration when manufacturing items by means of acetal injection moulding. Homopolymers are used for items which will be used in the condition of high fatigue, because they have a high resistance to its impact, and they also have high tensile strength. Copolymers, on the other hand, are used for parts which will be subjected to hot water impact or alkalis impact, because they have a high resistance to such impacts.

Parts which are made by the acetal injection moulding method comprise gears, bearings, plumbing fittings, valve housings, pump housings, auto fuel system parts, etc. These are uses where the properties of this material – toughness, resilience, and rewarding dimensional stability – are highly beneficial.

  • High termal stability
  • Gears, bearings, valves etc
  • Resistant to chemicals
  • Years of moulding experience

Furthermore, acetal is resistant to chemicals, and is especially resistant to alcohols and oils. It is also characterised by very low water absorption.

All these qualities are important when choosing what parts to produce by acetal injection moulding.

Acetal materials are processed easily by means of acetal injection moulding. Because there are not many adhesives suitable to join acetal parts, joining is implemented by means of snap fit joints, by threading or riveting. In some cases people can choose to weld acetal parts ultrasonically.

It should be noted that in the course of acetal injection moulding, shrinkage cannot be uniform in all directions

So round parts can become somewhat oval, and there can be some warpage of flat and thin walled parts. These peculiarities have to be taken into account during the design of parts to be made by acetal injection moulding, to obtain optimal parts.
