Avantajele produselor de turnare sub presiune din aliaj de zinc

I. The essence of die casting

　　The essence of die casting is that under the action of high pressure, the liquid alloy is filled into the die casting cavity at a very high speed through the movement of the injection punch, and then crystallized and solidified under pressure to obtain the casting.

　 Due to the use of metal molds, die castings have high dimensional accuracy, smooth surfaces, clear contours, and excellent surface quality. And the inherent quality of compact structure, high strength and high hardness. Die casting is suitable for manufacturing non-ferrous metal castings with complex shapes, thin walls and large numbers. It is an advanced precision part forming technology with high education.

  1. Excellent die-casting characteristics

　　Zinc alloy is a versatile, reliable, low-cost material, easy to die-cast production. Zinc alloy has good die-casting performance, so it is easier to die-cast products with complex shapes, thin walls and high dimensional accuracy. The thin-wall casting performance can achieve the requirements of product weight reduction and cost reduction.

  2. Good mechanical properties and processing performance

　　Compared with aluminum alloy and magnesium alloy, zinc alloy has higher tensile strength, yield strength, impact toughness and hardness, and better elongation. The surface of zinc alloy die-casting parts is very smooth, which can be directly used for poor treatment, and it is easier to make various surface treatments. Polishing, electroplating, spraying, painting, etc. to get better surface quality.

3. Efficient production

Production using hot chamber die casting machine, high production efficiency. The temperature of the molten metal is lower than 420℃ during die casting. A pair of molds can produce hundreds of thousands of products. The die-casting machine with advanced performance can realize fully automated production with low production cost.

II. Application of zinc alloy

Produsele din aliaj de zinc turnat sub presiune au cea mai bună calitate a suprafeței. În prezent, ele sunt utilizate pe scară largă în fabricarea de jucării, veselă, încuietori, decorațiuni hardware, piese turnate electrice și electronice, accesorii pentru baie, piese auto, fermoare, catarame metalice, carcase pentru ceasuri, ventilatoare, necesitate zilnice, aparate electrocasnice, echipamente pentru camere, audio, produse electromecanice și alte piese.
