PNP, which specialises in plastic injected moulded products, has installed one of Meech’s energy-saving air curtains on an injection moulding machines.

The firm had been experiencing problems with the injection moulding process, during which smaller and lighter items would sometimes stick to the moulding tool, preventing them from being released and collected for packing. This often caused jams in the injection moulding machinery.

However, with the new air curtains, these can now be fixed directly onto PNP’s moulding tools, allowing them to be positioned over the mould cavities with minimal separation.

“So far, we have modified and tested one injection moulding tool with great success, noticing reduced wastage levels and improvements in overall manufacturing times,” PNP business development manager, Nigel Brammar, says.

“The design of the air curtains allow ambient air to be sucked into the compressed air flow at ratios of around 25:1, meaning Meech’s air curtains are more economical compared to our previous air blast equipment.

“The compressed air supply required is substantially less than for a conventional air blast; in fact, basic testing on Meech’s energy saving air curtain suggests that it uses a fraction of the previous air demand. This aligns with our wider business policy of reducing energy consumption.”
