Types of Die Casting Available From JTR

Hot Chamber Die Casting

Hot Chamber Die Casting

Also known as gooseneck casting, the hot chamber is the most popular die casting process. A chamber of the injection mechanism is immersed in molten metal and a “gooseneck” metal feed system brings the metal into the die cavity. Hot chamber die casting machines are used for alloys of zinc, tin, and lead.

Cold Chamber Die Casting

Cold chamber die casting is often used to minimize machine corrosion. The molten metal is ladled into the injection system directly, eliminating the need for the injection mechanism to be immersed in the molten metal.

Cold Chamber Die Casting

Types of Pressure Die Casting

At JTR Machine, we can provide high-pressure die casting or low-pressure die casting according to your production needs to ensure product quality. High-pressure casting uses a hydraulic cylinder to drive the injection head to press the metal liquid into the mold cavity at high speed. Because it uses oil pressure and the pressure is high, it is commonly known as high-pressure casting; while low-pressure casting uses air pressure to hydraulically press the metal into the mold cavity, The air pressure is generally 0-2Kg/cm2, so it is generally called low-pressure casting.

Low Pressure Die Casting High Pressure Die Casting
Lower pressure, generally less than 0.08MPaHigh pressure, up to several hundred MPa
The molten metal flows relatively smoothlyMolten metal flows faster in the cavity
The cavity can be metal, sand, etc. (lower requirements for cavity materials)The cavity can only be metal
Can produce small and medium castings and large castingsUsually used to produce small and medium-sized castings
Castings can be heat treatedNo or incomplete heat treatment strengthened castings

Die Casting Price

  • Different die casting mold processing equipment will also affect the price.
  • The material side of the die casting mold has a great influence on the price of the die-casting service. Some die castings have special requirements, so it is also very important for the selection of die steel. Although they can be made, the price of different materials can vary by 20% to 30%.
  • Different die casting equipment also has an impact on the price. Different production equipment has different production capacity, labor cost and other expenses.

Why Choose JTR’s Die Casting Service?

The high degree of complexity – Die casting produces close tolerance parts that are durable and dimensionally stable.

Strength — Die cast parts are typically stronger than injection molded parts and more resistant to high temperatures. Wall thicknesses of parts can be thinner than for most other manufacturing processes.

Precision — Die Casting offers tolerances ranging from +/-0.003″ – 0.005″ per inch, and even as tight as +/- .001” depending on customer specs.

Material versatility — A wide range of Al, Zn, and Mg alloys.

Cost-effective — Stamping and die casting integrated installation. This can save installation time. And we pay for the assembly fee, you do not need to pay for the assembly fee.

What is Die Casting?

Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. The mold cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mold during the process. Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminum, magnesium, lead, pewter, and tin-based alloys. Depending on the type of metal being cast, a hot- or cold-chamber machine is used.

Features of Die Casting

Die casting is a casting method in which molten alloy liquid is poured into a press chamber, the cavity of a steel mold is filled at high speed, and the alloy liquid is solidified under pressure to form a casting. The main characteristics of die casting that distinguish it from other casting methods are high pressure and high speed.

  • In the die-casting process, the molten metal fills the cavity under pressure and crystallizes and solidifies at a higher pressure. The common pressure is 15-100 MPa.
  • The molten metal fills the cavity at a high speed, usually 10-50 meters per second, and some can exceed 80 meters per second (the linear velocity of the cavity through the inner gate—the inner gate speed), so the filling of the molten metal The molding time is extremely short, and the cavity can be filled in about 0.01-0.2 seconds (depending on the size of the casting).

Die casting is a precision casting method. Die castings made by die-casting have very small dimensional tolerances and high surface accuracy. In most cases, die-casting parts can be assembled and applied without turning, and threaded parts can also be cast directly.
