Rubber mouldings used in the production of metal castings.
Metal castings are central parts of engines and transmission that require precision masking. At the very least there will often be threaded holes, bores or spade connectors that need to be kept free from contamination. There are thousands of stock parts already available to cater for most requirements. Parts requiring greater precision may have more bespoke masking needs.
Preventing metal coatings from entering threaded holes, bores and contaminating spade connecters is an essential part of producing quality metal castings. Failure to mask effectively causes unnecessary rework costing time and money. Using silicone rubber masking devices to improve production quality and reduce costs is a sensible option.
The same silicone rubber devices are perfect for masking in anodising processes. Anodising applications are commonly machined parts requiring surfaces to be process free.
It’s also common to use gaskets when connecting castings to each other or other metal ancilliaries where there is fuel, lubricant or gas flow to maintain efficiency. Depending on the application, it may be a different type of rubber more suited to this kind of task and AFAC has found that Viton has the necessary qualities to resist oils and petrochemicals that can cause other rubbers to degrade.
AFAC has been supplying masking devices for castings in all kinds of applications including automotive, aerospace, rail and defence for years and in more recent years, AFAC has supplied viton mouldings to a wide range of engine and generator manufacturers.
