Overmoulding protects cables and
assemblies
The Werner Wirth overmoulding machine operates with both cable preparation and PCB assembly equipment, moulding strain reliefs, connector shells and grommets onto electrical cables.

Automatic crimper handles ultrafine wires
The Komax Gamma 255 is a fully automatic crimping machine for top-quality processing of ultrafine wires.
Traditional moulding materials are not well suited to these tasks, due to the high temperatures and pressures required, which can damage the base product.
These higher-pressure higher-temperature materials also require expensive steel mould tools.
Low-temperature low-viscosity thermoplastics are now available that can address the challenges of leading edge assembly requirements and allow improved reliability with reduced production costs.
Werner Wirth machines have now been developed to mould these materials quickly and accurately, even onto delicate products, using aluminium mould tools.
Being made of aluminium allows the tools to be manufactured quickly at very low cost.
Aluminium also has the advantage of increasing the rate of cooling of the moulded product.
With shorter cooling times the rate of moulding is dramatically increased.
