Tableware hardware casting

1,Guangdong alloy steel castingThe storage environment, temperature and humidity of aluminum products are suitable for mold growth.

2. The surface of the aluminum casting products of Dongguan Aluminum Casting Factory is mixed with super sister substances, which automatically absorb moisture into the air to form a corrosion reaction, and create an environment suitable for mold growth.

3. Due to corrosion reaction, the surface of aluminum castings in Dongguan Aluminum Casting Factory precipitates alkaline substances. After deliquescence, the temperature and humidity are suitable, and the mold grows rapidly.

4. The surface of the cast aluminum product has grease, plant fiber and other soil suitable for mold growth. Once the humidity and temperature are appropriate, the mold will grow rapidly.

Solutions for aluminum castings in Dongguan Aluminum Casting Factory:

1,Guangdong carbon steel castingDo not use refining metamorphic slagging agent containing sodium salt or magnesium salt, use refining metamorphic agent of NaF component, or N2 gas refining.

2. Do not use plant-containing fiber, do not use plant-containing fiber cutting fluid, replace the oil-based anti-rust cutting fluid.

3. The product cannot be stored in the open air for a long period of time, and fly dust accumulates on the surface of textile products.

4. The product packaging cartons stacked on the slabs should be wrapped with stretch film on 6 sides to be waterproof. After the products are soaked in water, they need to be ventilated and blown dry.

Lost wax castingAluminum annealing is to heat the workpiece. When it is heated to the proper temperature, the aluminum casting is slowly cooled according to the material selected, and the internal structure of the metal is close to equilibrium. Normalizing is to heat the workpiece to a suitable temperature and then cool it in the air. It is mainly used to improve the cutting function of the material, and it can also be used to finish die-casting some parts that are not in high demand. Quenching is to heat and heat the joint building, and then rapidly cool it in a quenching medium such as water, gas or other liquids. After this process, the produced steel parts will become hard and at the same time, the steel parts will become brittle.

Application of Aluminum Castings Aluminum materials and aluminum alloys have good fluidity and plasticity, so various complicated and difficult die castings can be made. Castings made of aluminum alloys and metal aluminum have high precision and surface finish. , This greatly reduces the amount of machining of castings, greatly reduces labor intensity, and saves electricity and metal materials at the same time.
