Die-cast zinc

with the die-cast zinc is pressed the liquid melt zinc - of an alloy under high pressure and extremely fast into a Druckgussform (mold). This procedure happens within approx. 20 - 30 milliseconds. Cast parts are produced by high precision, hardness and firmness.

Because ofthe relatively low melting point and a particularly close solidification interval of the zinc alloys particularly close tolerance and fastidious surfaces can be produced with the die-cast zinc. In this way the manufacturing of large numbers of items from a form is possible. The numbers of items can between 1000 Stück/h with small articles and 90 Stück/hwith majorities amount to. The form durability lies between 500.000 and 5 millions Cast parts.

die-cast zinc is suitable for smallest parts (z. B. Zipper claws) up to medium sized parts with complicated shaping (z. B. Housing for electrical appliances). In the die-cast zinc manufacturedArticles surround us daily. Many grasps and locks at doors, windows and gates are exactly the same from die-cast zinc such as model railways and model cars.

With older zinc products, which developed from unfavorable or contaminated alloy mixtures, partly the so-called zinc plague is to be observed. Here it comes to decomposition featuresthe metal structure, which lead to cracking, breaks up to the complete destruction of the product. This is in particular with old pieces of collecting tank like e.g.To determine model railways from the years briefly forwards or briefly after the Second World War regularly.
