MAPAL sealing rings: Lead-free and improved performance
MAPAL attaches importance to the production of sustainable tools and this claim also includes accessories and supplementary products. Traditionally made from brass, sealing rings for flanges and adapters are characterised by their high resistance to physical stress and excellent corrosion resistance. Sealing rings are used to manually close the clamping bore on HSK spindles and adapters and protect them against the ingress of dirt. However, like the associated holding screws, conventional brass products contain small amounts of lead, the release of which can have harmful effects on the ecosystem. Consequently, many countries introduced strict regulations to minimise the release of lead into the environment.
Environmentally friendly alternative
In response to the REACH regulation - the European Chemicals Regulation for the Registration, Evaluation, Authorisation and Restriction of Chemicals, which regulates the use of lead and imposes an obligation to inform users, MAPAL decided to go a step beyond the legal requirements. The company subjected its products to a critical review and looked for alternative solutions. In the meantime, new production of sealing rings and holding screws has been switched to environmentally friendly materials.
Produkt verbessert – Leistung gesteigert
Im Zuge der Materialumstellung beschäftigte sich MAPAL auch mit technischen Produktverbesserungen, die in einer Steigerung der Maximaldrehzahl der Abdeckringe um bis zu 100 Prozent resultierten. Eine zusätzlich auf den Ringen aufgebrachte Eloxalschicht, sichtbar durch die blaue Farbe, schützt diese wirkungsvoll vor Korrosion. Die Dauerfestigkeit der Abdeckringe bleibt auch in der neuen Ausführung gewährleistet und auf gewohnt hohem Niveau. Die Austauschbarkeit der Ringe ist sichergestellt.
