Zinc alloy pressure die castings are usually used in products with high appearance requirements, such as electronic cigarettes, U disks, furniture, perfume decorations, and other electronic appearance parts, mainly because zinc alloys have good surface treatment properties. Electroplating, baking paint, spraying, etc., the processed effect is much more beautiful than other materials, the surface will not have defects such as bubbles, impurities, and can highlight the texture of the metal.
The density is high, the quality is high, and the hand feels good.
It has good die-casting performance and can high quality die-cast products with complex structure and high precision.
Good mechanical resistance and abrasion resistance at room temperature.
When melting and die-casting, it does not absorb iron, does not corrode the pressure, and does not stick to the mold.
Easy to shape, low melting point, 385°.
Zinc alloy strength aluminum alloy is weak, and the tensile strength at high temperature and the impact performance at low temperature is significantly reduced.
Poor corrosion resistance.
Aging reaction, the shape, and size of the die-casting parts will change slightly after reacting with the chemical elements in the air for a long time.
Stainless steel precision castings, also known as stainless steel investment casting, refers to the formation of ceramics around the wax mold to form a shell for casting stainless steel. Once the wax patterns are formed, they are melted into the gate system, immersed in mud and sand to form a layered shell, and then replaced with molten stainless steel.
Size: 0.1 inches to 24 inch
Weight: a few grams to more than 50 pounds
Surface: smooth finish
Reliable process control and repeatability
Design and casting versatility
Mechanical properties are not as good as forgings. In sand casting, single-piece, small-batch, high labor intensity, unstable casting quality, many processes, and complicated influencing factors.
