Moulds for APG and LSR – for High-Quality Components

VOGEL moulds – either for APG process or silicone applications (LSR) – are dedicated to highest precision and reliability. Every single mould has exactly been adapted to the machine, granting high-quality components from the beginning. The moulds are designed and developed by means of technically most advanced 3D CAD systems. They meet the requirements on production, which are growing more and more complex and fast.

Long Service Life and Precision

With the modern mould arrangement it is possible to manufacture faultless dimensionally stable parts from the first shot. Each mould exactly fits the customer’s requests and provides a convenient, easy handling in perfect correlation with the clamping unit. Thanks to high-quality materials and high-tech thermal treatment, the moulds’ service life is very long.

Modular and Extendable

If requested, different – even complex – components can be manufactured with just one mould. The flexible APG moulds employ exchange kits or variable mould bricks. Every mould can have one or several independently moving core pullers. The modern block arrangement of the LSR moulds allows a short, easy change-over of insulators of various lengths.

Directly or Indirectly

All moulds – both for APG and LSR – can be equipped with direct heating or be heated indirectly via the heating plates of the machine. The moulds for LSR can either be brought to the required temperature electrically via heating cartridges or by means of heat/cool channels via external heating/cooling units.

Technically Matured

The applied materials and high surface quality result in a considerable reduction of the maintenance and cleaning efforts when changing the mould. In order to increase productivity, a mould may have up to eight cavities. As a matter of course we consider sophisticated pour-in systems as well as fully automatic demoulding and moulding systems.
