Mould Coatings

As a market leader in water-based process chemicals, ACMOS develops and produces coatings whose active substances are dispersed in water or solvent as a carrier medium.
ACMOS mould coatings are based on solid lubricants, such as graphite, boron nitride, aluminium, or molybdenum sulphide, which are integrated in an organic or an inorganic binder system.
ACMOS mould coatings offer many process advantages and lead to an improvement in the quality of the finished article.
Studies have shown that mould coating can double, and in some cases even quadruple lubrication intervals. If the moulds have been precoated, there is no need for lubrication, which is always seen as a disruptive factor in the production process, for about the first 20 minutes after a job change. So, the operators gain time to start the process, overcome initial difficulties and achieve higher output from the machine.
Also, during the entire production, lubrication intervals can be significantly extended, and mould lubrication can be kept to a minimum due to a lubrication buffer that the coating provides even several hours after a job change.
Extended lubrication intervals also reduce the rejection rate, having a direct positive impact on total costs. Especially for articles with a high mould change frequency, the use of a mould coating pays off quickly.
But a mould coating can do even more: the quality of finished articles can be significantly improved. Studies show that by combining the coatings with the usual lubricant, the rejection rate can be reduced significantly. The sliding of glass (gob) and metal (mould surface) as a tribological system causes friction and wear, which have a negative impact on the load and therefore on the article surface. This negative effect is shown by defects such as loading marks, washboards, or cracks. With a mould coating, problems in loading and article defects mentioned above can be avoided.
