Eliminate static charges in blow
moulding
Unwanted static charge can cause problems in plastics blow moulding and handling, but a range of static eliminator devices neutralise static charges and save time and costs.
Blow moulding is a high speed, high volume manufacturing process calling for the utmost accuracy, particularly during the actual moulding activity Unwanted static charge can cause problems early in the production process

The new 991R and 993R DC spark-free generator bars from Meech greatly improve operator safety by eliminating the incidences of flash-over.
In blow moulding it is essential that plastic parisons are completely vertical and aligned as they leave the extrusion head in order that they line up perfectly with the mould.
The presence of static charges can cause the parisons to be drawn to one side or the other resulting in poor delivery into the mould, misshapen and mis-blown bottles, wastage and process disruption.
With equipment that is operating such rapid cycle times, all such potential productivity and quality problems need to be addressed immediately.
Meech offers a range of solutions, including the installation of a Pulsed DC static elimination system that provides long range neutralisation of static charges without the need for air assistance.
Further along the production process, the generation of unwanted static charge can also create problems such as causing the empty moulded bottles to repel each other, even sometimes "jumping off" the conveyor track, and the attraction of dust contaminants.
The outcome is poor quality, inconsistent packing and reduced productivity.
Again, Meech Static Eliminators provides a variety of proven solutions to solve these manufacturing issues. Request a free brochure from Meech International ...
