The Principle Of Auto Casting Part Selection

The principle of Auto Casting Part selection
 Casting is a variety of Auto Casting Part to obtain the metal forming objects, that is, smelting good liquid metal, with casting, injection, inhalation or other casting method into the prepared mold, after cooling and other means of processing after grinding After the resulting objects with a certain shape, size and performance.
1. Low-pressure car casting, die-casting, centrifugal car casting and other Auto Casting Parts, because the equipment and molds are expensive, suitable for mass production. For small castings, you can use the horizontal classification or vertical classification of the box-free high-pressure molding machine production line, real shape modeling production efficiency is high, covers an area of less; for the pieces can choose a variety of box high pressure molding machine production line, gas Punching line to meet the requirements of fast, high-precision molding production line, core method can be used: cold box, hot box, shell core and other efficient core method. Medium batch of large castings can be considered to apply resin from hard sand molding and making core.
Single piece of small batch production of heavy castings, hand shape is still an important method, hand styling can adapt to a variety of complex requirements more flexible, do not require a lot of technology and equipment. Can be applied to water glass sand type, VRH water glass sand type, organic ester water glass self-hardening sand, clay dry type, resin self-hardening sand and cement sand type; for single-piece production of heavy castings, the use of pit molding method cost is low fast. Mass production or long-term production of stereotypes products using multi-box shape, split box molding method is more appropriate, although the mold, sand box and other investment began to high, but from the conservation of working hours, improve product quality to be compensated.
  2. Priority to the use of sand precision carbide castings. According to statistics, China or the international, in all casting production, 60 to 70% of the castings are produced with sand, and about 70% of which is produced with clay sand. The main reason is that sand casting is cheaper than other car casting methods, the production process is simple and the production cycle is short. So as the car's engine cylinder block, cylinder head, crankshaft and other castings are made with clay wet sand production process. When the wet type can not meet the requirements and then consider the use of clay sand dry sand, dry sand or other sand type. Clay wet sand castings Castings can be cast from a few kilograms to several tens of kilograms, while clay-dry castings can weigh tens of tons. In general, for large castings, cast iron pieces can be made of resin self-hardened sand, cast steel can be produced with water glass sand type, you can get the size of precision, smooth surface of the casting, but the higher cost. Of course, the precision of castings, surface finish, material density and microstructure, mechanical properties, etc., of sand castings are often poor, so when these properties of castings require a higher, other Auto Casting Parts, such as melts (Lost wax) car castings, die-casting, low-pressure car castings and so on.
   Casting application has a long history, as early as 5000 years ago, our ancestors will be able to cast copper and bronze products. Automotive castings are the most widely used metal liquid molding process. It is the liquid metal poured into the mold cavity, to be cooled after solidification, access to a certain shape of the blank or parts of the method.
