It is also ideally suited for use on plastic mould surfaces on which extremely high tensile and torsional forces act during the removal of injection-moulded plastic parts.
Sol-Gel System: the durable, non-stick coating that always gives good results
Over the years, we have managed to save a PET bottle manufacturer high investment costs by simply coating its moulds with Sol-Gel. Instead of buying expensive new tools, old moulds were coated. In this way, it is possible to increase production efficiency even under the new processing conditions, a factor of a prime necessity today.
Thanks to the new coating, the bottles no longer stick to the mould or release residues. A further advantage: maintenance of the production system can be carried out at longer intervals, thus reducing the duration of production downtimes.
In the case of this system, the procedure was quite easy: we removed the old coating and applied ours. The coating process requires minimal preparation. In a nutshell, it can be said that in the case of plastic extruders, a thinner blasting profile is required to achieve a smooth and durable surface finish and thus to have unchanging products over time.
After the application of the layer follows the curing phase, which allows the formation of a particularly resistant non-stick layer.
Other advantages include increased production capacity at optimum speed and reduced energy consumption.
