Die casting can be understood as pressure casting, which is a casting method in which molten alloy liquid is injected into a pressure chamber to fill the cavity of the steel mold at a high speed, and the alloy liquid is solidified under pressure to form the casting. The main characteristics of die casting differ from other casting methods are high pressure and high speed.

Die casting machine, die casting alloy and die casting die casting are three essential factors in die casting production.

The following describes the die casting manufacturing process and points to note:

1. Before starting the motor, first place the pressure relief valve handle in the pressure relief position, and release the pressure relief valve handle after the motor runs normally.

2. Before injection, the model must be heated to the specified temperature before being pressed into the metal solution.

3. At the same time, we should also be ready to die casting mold, installation, debugging, and then spray release agent, generally using automatic spraying, so we should first automatic spray can according to good, and debug release agent (release agent is generally purchased by the stock solution, need to be diluted, can be used).

4. Protective baffles should be used at the contact point of mold parting surface and gate, and operators must wear protective glasses. The operator shall not stand on the opposite side of the parting surface contact. In case the metal spatter hurts anyone.

5. Do not bring objects with open flame near the oil tank. When the temperature of the tank exceeds the temperature specified for the operation of the equipment, water cooling shall be applied.

6. Tools should be used when removing castings and pouring risers from die casting. After the casting is removed, the metal debris adhering to the mold and the air hole should be removed in time.

7. When the work is finished, the oil pump must be stopped and all valves closed. If the heat preservation furnace is used for metal liquid heat preservation, the power supply should be turned off and the ventilation equipment on the heat preservation furnace should be stopped.

8. After taking out the die cast, it is necessary to clean it, then cut the excess edge material, and then polish it. If the surface is to be treated later, clean it again after polishing.

For die casting manufacturing, different materials, there are different considerations, mainly temperature, and material characteristics.

For die casting release agent, our company is specialized in the production and development of release agent, not only die casting release agent, and metal release agent, used for forging, casting, cold extrusion, hot extrusion, copper casting, and polyurethane release agent, polyurethane sole, PU sole, car cushion; There are also release agents for composite materials, carbon fiber/epoxy resin, FRP, plastic, concrete, etc.

Die casting release agent: aluminum alloy, magnesium alloy, zinc alloy release agent, pure aluminum, copper release agent, no silicon aluminum alloy release agent, graphite, anode release agent.

Die casting release agent, die casting to provide efficient, environmentally friendly, water-based release agent; No carbon deposit, no black, no water lines, good stripping, high ratio.
