WD-40 for Mould Maintenance

Moulds and plastic moulding

A mould costs as much as a car, and rust on the cavity surface means a reject on every shot. Tooling care directly affects unit cost.

WD-40 provides effective, easy anti-rust cleaning and maintenance of moulds, extending their service life. It is also used as a release agent for certain plastics, improving productivity and saving labour and materials. Genuine products made in the UK, wholesale by the case, prices include VAT.

You know the WD-40 brand.

But do you know what it can do for your production?

WD-40 forms a dense protective film that stops moulds rusting, is easy to apply and comes off with a quick wipe. And if rust has already appeared, it helps remove it.
