Zinc and its advantages
Die-casting from zinc-alloy (zamak) is a method of precision casting and it is the most approximate to an ideal - direct change of raw-material to final product.
Die-castings can be characterised by comparatively high precision. They have smooth surface, thin walls and very good mechanical characteristics. They require only a little amount of after-casting machining and in many cases can be used directly after casting.
Die-casting means the way of casting during which the molten zinc (410˚C) is injected into a metal die by piston movement. Production time of casting is from 4 to 15 seconds, depending on casting weight. So it is very effective way of production. The waste material that arises during casting (sprues and gates system) is recyclable directly during production.
Parts made of zinc-alloys are resistant against atmospheric influence (do not corrode) and are stable on the air.
This is the reason why zinc die-castings are used at production of building and furniture fittings, in automotive industry, household appliances industry ...
