PLASTIC APPLICATIONS
Each of our products must meet very specific requirements, especially in the highly differentiated plastics manufacturing industry. Therefore, with the BÖHLER range, we are able to offer the plastics industry a range of field-tested tool steels adapted for each specific application. Depending on requirements, various steels or high-performance materials produced by powder metallurgy are used. For maximum machining precision and perfect plastic surface quality.
To meet the highest demands BÖHLER plastic mould steels are the ultimate solution to any application in the manufacture of mould and machine parts, meeting the highest expectations of users as regards shape, function, aesthetics, product quality and durability. BÖHLER steels are of a guaranteed consistent quality and developed for the most stringent future demands. As a mould maker you certainly know of all the demands a product should meet.
