Plastic moulding is a part of our everyday lives. Mobile phones, spectacles, car parts, computer components, etc. are all produced by use of plastic moulds. The materials required for making these moulds require unique properties to fulfill and meet the product quality. This is why it is critical to choose the correct steel material for your plastic product. This means that plastic moulding is a demanding branch of industry, so severe environments put the steel material under stress.
As a direct declaration, (Choosing the right steel type is the solution)
Due to the needs of the various plastics moulding applications, Bohler- Plastic mold Steels are ideal where high polishability, improved resistance to corrosive and/or abrasive polymers, high thermal conductivity, uniformity and reliability are required.
One of the main steel groups to meet all demands of plastic and PVC industries are BOHLER plastic mold stainless steel types. They are metallurgically balanced stainless grades that have been specially developed and continually refined to meet the needs of the evolving plastic moulding industry.
For example, BOHLER M303 EXTRA is stainless martensitic chromium steel, offering excellent toughness, corrosion and wear resistance. It is characterized by improved machinability and polishability. BOHLER M303 EXTRA was developed for improved homogeneity ensuring excellent usage properties when compared to 1.2316. The main cause of M303 success is the prevention of delta ferrite in the matrix.
The more advanced BOHLER plastic mold steel materials are nitrogen alloyed stainless steels. They have improved thermal conductivity due to very homogeneous microstructure.
Corrosion resistance is also one of the properties extensively required for tools and dies dealing with plastic materials of corrosive filler components
BOHLER plastic mold steel group is one of the major steel materials used in the following applications:
- Moulds for chemically aggressive plastics
- Moulds for household appliances
- Extrusion tools
- Moulds for fittings
Additional advantages of the plastic mold steels we offer in Egyptian market are the high mechanical properties and good machinability. Our material BOHLER M238 is the ideal steel material having these properties beside its high Hardenability, good electrical discharge machining, good photo etching properties and good polishability.
