Product Description
Low pressure casting refers to placing the mold above the sealed crucible, and then introducing compressed air into the crucible to generate low pressure on the surface of molten metal, so as to raise the molten metal from the crucible, fill the mold with riser and control the solidification casting method.Low pressure casting is a large thin-wall composite casting with good feeding performance, compact structure and easy casting. It has no riser and the metal recovery rate is up to 95%. No pollution, easy to realize automation. However, due to high equipment cost and low production efficiency, it is usually used for casting non-ferrous alloys.Low pressure casting is a casting method in which a liquid alloy is pressed into a cavity from bottom to top under pressure and solidified under pressure to obtain a casting. The sealed crucible is filled with dry compressed air or inert gas. With the pressure on the molten metal surface, the molten metal flows down to the riser. The mold is stably filled into the upper through the runner, and the filling pressure is usually 20-60kpa. After the casting is completely solidified, release the air pressure on the liquid surface, and the uncured molten metal in the riser and runner flows into the crucible with its own weight, then open the mold for casting, and then take it out.The production process of low-pressure casting includes the following four basic processes:1. Metal smelting and mold manufacturing.2. Preparations before pouring: including crucible sealing (installation of sealing cover), slag removal in riser, liquid level measurement, sealing test, mold matching, mold or mold fastening, etc.3. Pouring: including liquid lifting, filling, pressurization, curing, pressure relief and cooling.4. Demoulding: including loose molding and casting.

Low-pressure casting or Vacuum casting aluminium process enables the tailored production of large-volume aluminum cast parts in small batches. A semi-automated procedure, low-pressure casting is particularly superior to the familiar method of aluminum gravity casting for large, rotationally-symmetrical molded parts with complex geometries. KarryCorp manufactures aluminum alloy low-pressure diecast parts weighing up to 250 kg. KarryCorp delivers more than just high quality cast parts - If needed, we assemble the cast parts with production parts in additional steps to form ready-to-install assemblies.As a specialist in low-pressure casting of small and medium-sized batches, KarryCorp can offer Low-pressure casting at very competitive prices. Low-cost molds for low-pressure diecast parts give our customers a decisive advantage.
Advantages of low-pressure gravity die castingThe mold-filling properties of low-pressure casting make it suitable for thin-wall, large surface parts. Low-pressure casting produces a fine-grained, very dense structure with attractive mechanical properties due to the controlled, low turbulence form-filling process and the fast, oriented hardening of the aluminum melt in the metal permanent mold. This largely prevents porosity and shrink holes. Low-pressure diecast aluminum parts have a high dimensional accuracy and surface quality. Cast aluminum possesses good electrical conductivity and superior thermal conductivity which makes aluminum a desirable material in machine building, automobile construction, and the electronics industry. In addition, the fact that aluminum parts are up to two-thirds lighter than those of cast iron makes cast aluminum a desirable alternative. Undercuts and cavities in cast parts can be achieved by using core inserts. Low-pressure casting is generally suitable for 200 - 1,000 castings of large-volume parts, however batch sizes of 50 units are sometimes economical. For a few medium-size cast parts weighing up 6 kg, we recommend aluminum gravity casting. For thin-wall cast parts in series up to 50,000 units, casting is the more economical method.
