zinc die casting-Advantages And Disadvantages Of Die Casting

What is Die CastMulti slider die casting machineing?

Die casting is a special metal casting。 It is an advanced method with a long development history on the basis of common metal casting technology。 This process， the molten or semi-molten state of the metal into the die casting machine pressure chamber under high pressure， the metal to high-speed filling into the cavity of the die-casting mold， and then the molten or semi-molten state of the metal will be solidified to the desired mold。 This is a highly efficient precision casting。die casting design development trend is to require better overall performance， higher precision， less allowance smooth surface castings。 In addition， the energy-saving requirements and increasing the voice of the community to restore the natural environment。 In order to meet these requirements， the new cast alloy development， smelting new technology and new equipment correspondingly。

Advantage of Die Casting Process

First， quality of die castings is good。 Casting size is accurate， stable， good exchangeability。 It can make the surface of the particles is thinner， elongation tissueMulti slider die casting machine density compact metal castings， and more compact metal surface hardness， higher density。 This method is suitabledie casting machine for the use of complex thin-walled metal castings， zinc alloy die casting thin-walled aluminum alloy thin-walled 0。5 mm to 0。3 mm， In addition， it is very suitable for the production of complex castings cannot use other methods。 Second， productivity is high。 The productivity of the die casting method is higher than traditional wet sand and resin sand casting process， however， far less than the automatic die casting mold。 However， aluminum castings， it can achieve high production efficiency。Die casting Third， it is economic。 The accuracy of the size of the die casting， surface finish， so the use of die casting without machining or processing can be a small amount， which not only provides the utilization rate of the metal， butzinc die casting also to reduce the processing equipment， die castings with good resistance to wear resistance， insulation and permeability， so they can instead of part of the assembly and simplify the production process not only saves time but also save the raw metal。

Disadvantage of Die Casting Method

In general， diezinc die casting castings have some stomata， and metal casting cannot heat the production， die-casting method has no effect on concave metal， in addition， it is not suitable for small-volume parts production， due to the high cost of the die-casting and high production efficiency， so small batch production is not economical。 The die casting method is widely applied to the casing industry， now， it is used not only for non-ferrous alloys such as zinc， aluminum， magnesium， copper， and is also used for cast iron and steel casting。 It is widely used in various industries of the national economy， such as weapons， cars， the aerospace and TV computer， agricultural machinery， medical equipment， and so on。
