Plastics processing is easier and more cost-efficient with ATC thin dense chromium

Difficulties in demoulding as well as problems associated with wear to moving parts, cores, mould inserts and slides occur much later than usual due to lower chemical reactivity and a significantly improved abrasion behaviour, especially in the case of strongly glassfibre reinforced or otherwise enriched plastics. The parts therefore do not have to be cleaned as often, and any deposits that may have developed can be removed in a shorter time.

Worms, worm tips, nozzles, shut-off needles for hot runner systems, mould cores as well as moulding plates also display greatly reduced adhesiveness.

The technology that is used for the process even makes it possible to coat recesses on the tool with the same coating thickness. The ratio of depth to size of the recess does not change. The coating is evenly deposited on the contours of the tool, even if the tool has a complex geometry.

The following benefits can lead to increased productivity and the associated cost reduction:

• Higher production reliability, shorter machine shutdown times
• Lower maintenance costs
• Better demouldability
• Lower consumption of separating agents
• Shorter cleaning times and longer cleaning intervals
• Reductions in hot cracking during extreme fluctuations of temperature
• No impact on thermal conductivity due to coating, e.g. with regard to Ampco mould cores.

The pretreatment and finishing treatment for visible surfaces is an especially important step in the process. We advise you to consult ATC before carrying out such treatment; our advice is to commission only service companies recommended by ATC to carry out this type of treatment.
