All coatings can be applied to any type of mould regardless of its type origin or condition, whether the mould is mild steel or cast aluminium - BMC™ coatings can give any mould a new lease of life.

Traditionally the surface of moulds can be treated with sand or bead blasting, shot peining, hand sanding or hand polishing. Prior to moulding in plastic the surfaces of these moulds have to be cleaned and coated with a proprietary release agent. There is a wide spectrum of coatings available, all with slightly different release properties – this in itself creates a significant variable in the final size, shape and appearance of the plastic part. However, by far the biggest factor in this equation is the person who is applying the release to the mould surface – if he applies too much release agent, the plastic part releases too soon from the mould surface and excessive warpage occurs – too little release agent and the part sticks. It can also be argued that, because release agents are in fact semi-permanent, they degrade each time a part is made, so even with all other variables remaining constant, no two mouldings will be exactly the same.

To overcome these shortcomings Maus have developed the BMC™ range of permanent release coatings.

At the moment there are four coatings available:-

• BMC™ Standard -General purpose applications imparts a semi-gloss finish to the moulded plastic part.
• BMC™ Matt -General purpose applications where a non-shiny surface is required or preferred.
• BMC™ Metallic -For use with special materials, such as XLPE or Plasma treated PE which are very harsh on conventional release agents and/or are very difficult to demould.
• CMC™ Applied specifically to flanges to help protect them from excessive damage and to ensure ease of operation of the mould
