HOT CHAMBER DIE CASTING

Product Details

hot chamber casting means that the pressure chamber is immersed in the liquid metal in the heat preservation melting crucible, and the part is not directly connected to the engine base, but is installed on the crucible. It is suitable for die-casting zinc and other non-ferrous alloy parts with low melting points, and can be widely used in industrial sectors such as automobiles, motorcycle parts, instruments, household hardware, and household appliances.

Hot Chamber Die Casting Capability

Compared with cold chamber die casting, its injection pressure is much smaller, generally around 7 to 14 MPa, so hot chamber die casting machine generally does not have a pressurized hydraulic cylinder. Due to the long-term sinking of pressure chamber components in molten metal, hot chamber die casting is mostly used for die-casting zinc alloy and other low melting point alloy castings. Since no additional pouring operation is required, the hot chamber die casting machine saves cycle time and has higher production efficiency than the cold chamber die casting machine. We provide the whole hot chamber process (from die design to transportation).

Advantages of Hot Chamber Die Casting

Hot chamber die casting is suitable for die casting of low melting point alloys such as zinc alloy. Compared with cold chamber die casting, it has many advantages: easy to realize production automation, high labor productivity, less metal consumption, stable process parameters, better quality of die castings, and improved working conditions.

Advantages of Hot Chamber Die Casting

Hot Chamber Die Casting Alloy

Hot chamber die casting has molten liquid and semi-liquid metal in the metal pool, which fills the mold under pressure. At the beginning of the cycle, the piston of the machine is contracted. Pneumatic or hydraulic pistons squeeze the metal and fill it into the mold. Generally speaking, the hot chamber die casting process is used for alloys of zinc and other alloys.

Quality Control Of Hot Chamber Die Casting

in a hot chamber die casting machine production process, selecting the appropriate process parameters is a prerequisite for obtaining high-quality castings and exerting the maximum productivity of the die-casting machine, and is the basis for the correct design of the die-casting mold.

During die-casting, there are many factors that affect the filling and forming of the alloy liquid, mainly including injection pressure, injection speed, filling time, and die casting mold temperature. Due to the low heat capacity of the zinc alloy, the injection system of the hot chamber die casting is required to provide sufficient energy to meet the requirements of fast filling.

FAQs of Hot Chamber Die Casting

Q: What is the difference in performance between hot chamber die casting and cold chamber die casting?

The hot chamber die-casting metal has a low melting point, the same production efficiency, high casting quality, and high quality stability of the die casting; the cold chamber die-casting metal has a high melting point, low production efficiency, and low quality stability of the die casting.

Q: What are the characteristics of hot chamber die casting machine?

The operating procedure is simple.

The temperature fluctuation range of molten metal is small.

Less consumption of metal materials.

Impurities in molten metal are not easy to carry.

Long-term use will increase the iron content in the alloy.

The injection pressure is relatively low.

Suitable for die casting of low melting point alloys such as zinc alloys.

Q: What do hot chamber die casting machines and cold chamber die casting machines have in common?

The mold clamping mechanism of the hot chamber die casting machine is the same as that of the cold chamber die casting machine. Both use hydraulic drive connecting rod mechanical mold clamping mechanism. There are two injection speeds of slow injection and fast injection, using non-pressurized injection and PLC control.
