Mechanical engineering plastic solution

Plastic Solution for Mechanical Engineering

Traditionally, mechanical engineering likes to use steel or metal alloys in order to get the high mechanical strength and precision of the components. But the metal materials also have their own inevitable disadvantages, such as heavyweight, extra lubrication needed, no resistance under corrosive conditions, and so on.

So nowadays, high-performance engineering plastics are gradually replacing metal and the trend is becoming more and more popular. The plastic material has many benefits that the metal is incomparable, such as good chemical resistance, lightweight, electrical insulation, and etc.

Plastic is always an ideal solution for mechanical components like gears, seals, sliding elements, valve seats, and other applications.

Keward provides a wide range of high-performance engineering plastics and has extensive application experience. We could not only provide high-quality materials but also offer practical suggestions on materials selection, design, and machinability.

 
Solutions for Mechanical Engineering

Corrosion resistance

For corrosive working environments, the metal materials may have some problems. But the plastics like PTFE, PEEK Virgin and others could cope with.

Sliding optimized materials

The self-lubricating plastics and these with special additives could enhance the sliding properties and wear resistance. Such as Oil filled nylonPA 6 GPTFE, PEEK PVX, Acetal, and so on.

Light weight

Many low specific density materials are useful in aviation, moving applications in order to achieve weight limitation, higher operating speeds, and less energy consumption. Plastics like ABS VirginAcetalPA 6 G are recommended.

High mechanical strength

The materials which are reinforced by the glass or carbon fiber always show better mechanical strength, higher stiffness, and are more stable under the condition of high temperature and high pressure. Recommend plastic PEEK GF30PEEK CF30PPS GF40, Ultem 2300.

Impact resistance materials

Impact resistance plastics should have the property that components need to withstand frequent impacts without cracking. Recommend materials like ABS ViriginPA 6PC Virgin, HDPE.
