Points For Attention In The Use Of Aluminum Alloy Die Casting Die
Dec 06, 2018

Some die-casting factories with high production costs and low added value have difficulty in production and operation, while those die-casting enterprises with strong strength and high added value are growing steadily in the market competition. With the continuous expansion of enterprise scale, some die-casting enterprises are also directly engaged in the follow-up processing of various castings to produce finished products, while some parts manufacturers (such as automobile and motorcycle manufacturers) have set up special die-casting workshop to realize d.IE casting parts.

Attention should be paid to the use of aluminium alloy die casting die. Many times you make mistakes if you don't pay attention to them. We should pay special attention to the following points:

1. In the beginning of production process, the die must be preheated to prevent the hot metal from suddenly encountering cracks in the cold die. Spray lamp, liquefied petroleum gas and mould temperature machine are used to preheat the complex mould, and slow pressure jet is used to preheat the simple mould.

2. If the die is equipped with neutron control, attention should be paid to the absolute prohibition of signal line connection between die casting machine and die. The reason is very clear. In daily production, it is difficult to avoid watermarks on the signal line, or the winding joint is easy to break, resulting in short-circuit connection with the machine tool. If the signal is incorrect, an alarm should be issued. Motion shutdown delay time, heavy signal confusion, die top bad. Cause unnecessary losses. Pay attention to the stroke switch.

Aluminum alloy die casting is a kind of high performance, high precision and high toughness parts, which can be used in automobile, electronics, household appliances, motors, communications and other industries. Because of its five characteristics, it can also be used for large aircraft, ships and mechanical parts.

Firstly, the durability of aluminium alloy die castings is good. It mainly uses aluminium as raw material, makes full use of its strong stability and oxidation resistance, and has the characteristics of rust-free and corrosion-resistant. The classical powder spraying and fluorocarbon coating are used on the surface of the castings to keep the colour of the castings unchanged for a long time.

The plasticity of the castings is good. Because of the good ductility of aluminium, castings can be used to design various shapes, tough castings, reusable, and have a wide range of applications.
