Ano ang pagkakaiba sa pagitan ng die casting at casting?

Die casting is a specialized type of casting that uses high pressure to force molten metal into a reusable steel mold (die), enabling high-speed production of complex, precise parts with smooth surfaces.

Traditional casting (like sand casting or pamumuhunan paghahagis) typically relies on gravity or low pressure to fill disposable molds (hal., sand, keramika), making it more versatile for larger, simpler shapes but with slower production and rougher finishes.

Die casting suits mass-produced metal parts (hal., mga bahagi ng automotive), while general casting covers broader applications.

1. The definitions of die casting and casting are different:

Die casting is a metal casting process characterized by applying high pressure to the molten metal in the inner cavity of the mold.

The mold is usually made of a higher strength alloy. This process is somewhat similar to injection molding.

Casting is a method of pouring liquid metal into a casting cavity that is adapted to the shape of the part, and waiting for it to cool and solidify to obtain parts or blanks.

Die casting process

2. The processes of die casting and casting are different:

The essence of pressure casting (referred to as die casting) is to fill the die casting mold cavity with liquid or semi-liquid metal at a high speed under high pressure, and to form and solidify under pressure to obtain castings.

The casting process can be divided into three basic parts, namely casting metal preparation, paghahagis ng amag paghahanda at paghahagis processing.

Ang paghahagis ng metal ay tumutukoy sa materyal na metal na ginagamit para sa paghahagis ng mga paghahagis sa produksyon ng paghahagis.

Ito ay isang haluang metal na binubuo ng isang elemento ng metal bilang pangunahing bahagi at iba pang mga metal o di metal na elemento.

Ito ay karaniwang tinatawag na isang paghahagis haluang metal, pangunahing cast iron, cast bakal at cast di ferrous alloys.

Ano ang Precision Casting

3. The casting precision of die casting and casting is different

Die casting ay isang katumpakan paghahagis paraan. Ang dimensional tolerance ng die castings cast sa pamamagitan ng die casting ay napakaliit at ang katumpakan ng ibabaw ay napakataas.

Sa karamihan ng mga kaso, die castings ay maaaring binuo at inilapat nang hindi lumiliko, at ang mga threaded parts ay pwede ring i cast ng diretso.

Paghahagis, natutunaw na metal, paggawa ng mga castings, at pagbubuhos ng tinunaw na metal sa mga castings.

Pagkatapos ng solidification, isang metal na bahagi blangko na may isang tiyak na hugis, laki at pagganap ay nakuha.
