Micro injection of Zamak under pressure

Zamak micro-injection in a hot chamber makes it possible to produce parts weighing a few grams with the following technical advantages :

• Injection of complex and precise parts.
• Production of parts with up to four drawer movement axes in addition to the mould opening axes.
• Reduced production costs through very low metal feed loss and fire loss.
• Feeding in the direction of the parting line without 90° bends as in conventional presses.
• Quick mould change on the machine (cavities and drawers).
• In some cases, automatic separation of the feed (sprue/runner) and the part at the time of injection.
• Parts with little burr and therefore no need for cutting.
• Reduction of part finishing operations.

This technology also allows a reduction in the cost of moulds:

• The moulding parts contain only the impressions and cores without the need to invest in a heavy casing as in conventional presses.
• If the part requires drawers, the sliding systems are already included in the "cross" integrated in the machine structure.
• It allows a reduction in the number of impressions because the injection rates are fast and are adapted to large series.
• The indentations in the zamak injection have a long service life.
