With the rapid development of the metal molding process, Tesla first used an integrated breakage body to combine 70 parts in the matrix molding process (currently reduced to 2 rooms, and it will be combined in the future) . Many car manufacturers have followed, and body technology in all-in-one of naturally has its unique charm. So, what is metal casting technology? Today we are making a brief introduction.
What is the casting
Molding is the process of using the three main elements of the machines, molds and alloys to unify pressure, speed and time. High pressure and high speed, and the process of crystallization of high pressure solidification to form a flow.
Casting Die equipment converts the electrical energy of the engine through the engine to the hydraulic energy of the pump, in order to carry out the action (that is to say to turn on and extinguish the mold, and the metal melting into the mold cavity).
The shooting part of the molding process is to use the energy of the hydraulic system to promote punch, thus pushing the melting metal to the mold cavity. Before the melting metal enters the type of mold, it is called a mounting channel called the flow channel and a smaller cross area called the port. The port of casting has the effect of accelerating the metal flow.

Excellent and disadvantages of the matrix casting technology
advantage:
1. Metal parts with complex shapes, light contours and thin walls and a deep cavity
2. High production efficiency
3. The rate of use of materials is high and only a small amount of subsequent treatment can be obtained to obtain the form of the required product.
default:
1. There are often air holes and mixed oxidation objects in molded rooms.
2. The size of the molding is limited and the type of alloy is limited.
Main alloy of Die -Cast
Casting alloys are one of the key elements of breakage production.
Al-Si alloy: The crystalline temperature interval is small, and the silicon phase in the alloy has a great potential heat of solidarity and a large heating capacity, and the line contraction coefficient is relatively low.
AL-MG alloy: good room for room temperature strength. Strong corrosion resistance, poor flow performance, fluctuations and wall thickness effects of mechanical properties are relatively important.
Alloy al-Zn: Once the molding of the matrix was failed, it can obtain high mechanical properties.
Manufacturers of production of breakage equipment and breakage equipment
The selection of casting Die machines has a very significant impact on many aspects such as product quality, production efficiency and management costs in the breakdown production process. To this end, a reasonable choice of applicable casting machines is a very technical and economical work.
Classification of the DI molder machine
Hot Room Die -Casting Machine: Zinc alloy, magnesium alloy, etc.;
Cold Room Die -Casting Machine: Zinc alloy, magnesium alloy, aluminum alloy, copper alloy, etc.;
Vice Die -Casting Machine: Zinc, aluminum, copper, lead, tin.
The difference between the heat chamber and the cold room is whether the shot machine shooting system is dipped in a metal solution. The Die casting machine can also be divided into horizontal and stand.

The current application of the matrice casting technology
Based on the characteristics of high production efficiency, complicated flow and high precision, the matrix breakage process is widely used in the automobile, tractor, electrical instrument, telecommunications equipment , aerospace, medical equipment and daily work industries. The main parts produced by matrix breakage processes include the body of the engine cylinder, the cylinder head, the gearbox, the engine cover, the instrument and the hull and the camera support.
Chemical application in matrix molding technology
1. Penta oil
During the checkout process, whenever the press is carried out, the punch must be in contact with the punching oil once and rub the part once. The flexibility and reliability of the movement of the shooting mechanism depend on the softness of the movement of the tap and the stability between it and the English Channel. The performance of the shooting system is intended for the production of a high quality matrix (the casting should not be loose, none of the metal mixed, while guaranteeing the precision of the size and the mechanical properties), controlling the metal pressure During the loading period and the metal which is compressed in the flow shape. We can say that the absolutely reliable punch system is the soul of the successful duration. And good lubrication performance is the key to ensuring normal shooting system.
2.
During the casting, the mold is constantly heated by liquid metals at high temperature and its continuous temperature to increase. Excessive mold temperatures will cause mold defects, such as mussels, bubbles, cracks, heat cracks, etc. At the same time, the mold works in a high temperature environment for a long time. In order to relieve or solve the above problems, in the production of parts, spray or coating measurement measures are often used.
The dental agent is a functional substance between molds and finished products. It can form a film of uniform lie on the surface of the mold, so that the shape of molding can be separated, and the product is complete and post-resistant.
3. Fight liquid pressure oil
The equipment in the event of a cash register works in high temperature environments. Daily leaks or emergencies such as pipelines and joints have made traditional mineral pressure oil have hidden fire dangers, and a serious threat to the safety of equipment and operators.
Consequently, flame resistance is used to ensure the stable operation of the hydraulic system under pressure and the environment at high temperature under pressure conditions.
