New innovative components for injection moulds Venting & valves

New innovative components for injection moulds

Growing competitive pressure forces mould makers to produce multi-cavity moulds. These not only mean a higher risk: if they cannot be operated reliably, the injection mould may come to a standstill very quickly. WEMA presents two new components for this purpose.

Newly designed venting system for injection moulds

One of the most frequent causes of complaint during the production of plastic parts is burn marks. The reason is insufficient venting of the cavity. The newly developed venting system "Ecovent" works on the basis of Bernoulli's principle and prevents trapped gases from escaping into the part surface.

Plasticizing Systems Heated by Natural Gas – Distinctly Lower Energy Costs Energy efficiency

Plasticizing Systems Heated by Natural Gas – Distinctly Lower Energy Costs

In the search for potential savings in plastics processing, energy consumption is increasingly attracting the focus of attention – after all, electricity costs that are already high are set to rise even higher. At the same time there is growing preparedness to make an active contribution to reducing CO2 emissions. Injection moulders achieve both objectives with a plasticizing unit heated by natural gas. Natural-gas heating systems can be retrofitted, pay for themselves in a short time and, most importantly, they are safe.
