Surface treatment of products by die casting manufacturers

Casting is a metal smelting process in which the gravity of the metal is used to cast the metal in a mould. Aluminum alloy die casting is a cast metal that plays an important role in many fields. In this article, the manufacturing process of aluminium alloy die casting and the surface treatment technology of aluminium alloy die casting are described and analysed in brief.

What are the surface treatments for aluminium alloy die casting?

Baking process

The baking process is to spray the aluminium alloy with phosphate and then bake it afterwards, so that the coating is not only anti-corrosive but also bright and wear-resistant and not easy to fall off. The purpose of the pre-baking treatment is to obtain a good coating, which plays a very important role in the painting process.

Sandblasting

This is a process commonly used for aluminium products, where a layer of fine sand is sprayed on the surface of the product to enhance the coefficient of friction on the contact surface and to increase the reliability of the joint.

Electroplating

Electroplating is the process of depositing a metal or alloy onto the surface of a workpiece using electrolysis to form a uniform, dense, well-bonded layer of metal. The main purpose of electroplating is to prevent corrosion, protect against decoration and resist wear.

The surface quality requirements of die casting manufacturers are very high. aluminium alloy die casting needs to meet the characteristics of high dimensional accuracy and low surface roughness.

How is aluminium alloy die casting formed?

Aluminium alloy die casting is mainly formed by die casting. This is a casting process in which a molten alloy is poured into a press chamber, which fills the cavity of a steel mould at high speed and allows the alloy to solidify under pressure to form the casting. The use of aluminium alloy die casting greatly reduces the machining capacity of the casting machine, greatly reduces labour intensity and saves electricity and metal materials.

The quality requirements of die casting manufacturers

First of all, die casting manufacturers are very strict in their choice of materials. With the continuous development of the aluminium die casting industry, the renewal and innovation of various generations of products require a wide variety of aluminium die castings with complex shapes and high precision requirements. High performance, high precision and high toughness are the basic requirements of the material. Secondly, the geometry and size of aluminium alloy die casting should be in accordance with the provisions in the casting drawing.

In a word, under the premise of meeting the function of the product, reasonable design of die casting, simplifying die casting mould structure, reducing die casting cost, these are the basic requirements of die casting manufacturer for the product.

Casting aluminium alloy has some advantages that other castings cannot match. The flexibility of die-casting aluminium can make it into parts with complex shapes.
