Zinc pressure die-casting

Initial tests are free of charge.

Manual and subsequently automatic tests can be carried on die-casting machines of over 125 tons. Results on smaller machines are achieved only with automatic systems that comply with the production schedule.

The only reliable data that we could verify concern the production of cover-switch plates with an amount equal to 0.002 g per plate. Often, wax is hardly visible during the spraying stage, and this can be a problem. We also have a client who consumes on average 5 Kg of wax a month, working 16 [...]

Provided that the correct heat management of the mould is positive, wax is efficient at a temperature of up to 260 °C.

The improved flow and release obtained with wax facilitate and improve the lubrication stage. Some of our clients manufacture pump bodies, air-pressure reducers, pneumatic valves, and occasionally lamps, without changing type of product.

Wax melts at 80 °C. It reaches its maximum efficiency when it exceeds 100 °C, which is the standard temperature of the production cycle. Only extremely light productions can experience temperature problems.

When wax comes in contact with the mould, it melts and, due to its chemical and physical properties, it expands, reaching the most hidden spots.

Wax is composed of the active substances of the release agent and does not contain solvents or water, which are only vehicles.

During the polishing and painting stages, the hydrogen hidden under the surface tends to expand due to the heating process it undergoes, thus creating micro-cracks, which are visible only when the piece is finished.

Yes! Our clients confirm it. Due to its heat-melting properties, wax increases the zinc flow, thus facilitating the filling of the casting. As a result, the pieces produced will have a more compact surface, even thanks to the absence of oils.
