What is the difference between Lpdc and Hpdc?
What is the difference between Lpdc and Hpdc?
LPDC is used when selecting castings with high air-tightness requirements. The production batch is large, and small and medium-sized non-ferrous metal castings without tightness requirements are HPDC. The difference is that LPDC parts can be strengthened by heat treatment, and the toughness can be greatly improved.
What are the different types of pattern?
Solid or Single Piece Pattern. Single piece pattern is the cheapest pattern among all other types of pattern.
Why is Hpdc used?
HPDC mainly used for the mass production of non-ferrous metals such as aluminum, magnesium, zinc, copper, etc., and it is widely used in industries such as automobiles, meters, electronics, aerospace, lighting, furniture, mechanical, hardware, and communication, etc.
What is Hpdc?
High-Pressure Die Casting (HPDC) is an extremely efficient manufacturing method for producing various product forms. The process forces molten metal at high speed, and high pressure into a closed steel die cavity. The die has a stationary and moving half, both of which are mounted to the die casting machine’s platens.
What is metal casting defect?
Pouring metal defects include misruns, cold shuts, and inclusions. A misrun occurs when the liquid metal does not completely fill the mould cavity, leaving an unfilled portion. Cold shuts occur when two fronts of liquid metal do not fuse properly in the mould cavity, leaving a weak spot.
What is difference between Hpdc and Lpdc?
What is HPDC process?
What is Hpdc and Lpdc?
Common die casting methods include high pressure die casting (HPDC) and low pressure die casting (LPDC). Factors to consider when deciding which die casting process is best for your needs includes component complexity as well as casting cycle speeds.
What is Lpdc?
Low-pressure die casting (LPDC) is a common process used in foundries today in which molten metal slowly fills the die, reducing turbulence. Automotive applications include wheels, as well as suspension, steering and engine components.

What is the process of melting and casting?
Melting and casting 1 The metal of correct composition is melted in a suitable furnace 2 The molten metal is now taken in ladles and poured into the moulds 3 The moulds are then allowed to cool so that the molten metal in the mould solidifies. 4 Casting is then taken out by breaking the moulds and they are sent to the cleaning section
What products can be produced by the casting process?
Products with very complex shapes, hollow sections, complex internal cavities, and irregularly curved surfaces made of metals that are difficult to machine can be easily produced by the casting process.
What is the size of a casting?
Casting is made from any metal that can be melted and can have any shape the designer desires. The castings can produce in sizes ranging from a few mm to several meters. Casting can weigh from a few grams to tons.
