Usage of high pressure hot chamber die casting machine:

High Pressure Hot chamber die casting machine widely used for low melting point alloys. Zinc/zamak die casting parts, lead alloy die casting parts, tin alloy die casting parts etc.

Mostly the machine always be used to produce zinc alloy die casting parts, the machine also named: zinc die casting machine, zinc injection machine.

Compare with cold chamber die casting machine, this machine is small. Its key function is injection work, so it also called: small die casting machine, small zinc injection machine, small high pressure inject machine.

The advantages of HD special melting pot goose-neck structure:

Special designed goose neck structure with pot, which keep alloy melting leverl same with injection nozzle. That reduce the air sapce of gooseneck to mold cavity. Finished die casting parts inside air holes are reduced sharply.

  1. Pot material made from special stainless iron.

  2. Molten metal alloy flow into hot chamber directly.

  3. Gooseneck structure be cast together with pot.

  4. Gooseneck structure connect with nozzle, which has a designed angle to keep molten metal level same with nozzle hole. That avoid many air be push into mold cavities.

What is the high pressure hot chamber die casting working process?

1.Melting Furnace Pot

Electric heating tubes heat metal alloy to molten state. (If first time use the melting pot, no alloy cover the electric heating tubes, we need pour molten alloy to the pot or use burner to melt metal blocks in pot firstly. When metal alloy covers the heating tubes, machine electric heating method can be used. )

2. Hot Chamber Injection Process

1st. Die casting die is clamped and the injection plunger rises, opening the hot chamber hole, allowing molten metal flow into the chamber cylinder.

2nd.The plunger seals the hot chamber hole, pushing the molten alloy through the gooseneck and nozzle into the mold cavities where it is held under pressure until metal alloy solidifies.

3rd.After the metal has solidified in the cavity, the plunger is withdrawn.

4th. Die casting machine movable platen move back and mold opens. Die casting parts be eject out from movable die half by ejector pins.

5th.Lubricating and cooling mold cavity. Die casting mold temperature is about 150℃.

6th>Mold closes and to start the next injection cycle.
