FEATURES of S.A. COSUN Die Casting System

Over 30 years , we have been maintaining　reserch and development of casting machines,die structures, casting methods and processing of molten metal in Low pressure die casting system.We made up this system as <S.A. LDP> and call it <SAL CAST>.The features of <SAL CAST> are explained as follows.

１.Casting machine

(1) Simple structure and unique extrusion (patented)

(2) Quick change of molds. (in 5 mins)

(3) Molten-metal intermediate stop system

Keep the surface of molten-metal near the mold gate

2. Die structure

(1) Simple structure

(2) The temparature can be controled.

<Water-cooling, mist and air-cooling> can be used as cooling medium.

3. Cating method

(1)Molten-metal is highly clear

The gas content is under 0.18cc/100g and the oxide content is small

(2) Less oxide is produced comparing with gravity casting method.

(3) Dual-sided glittering aluminum wheels for motor-bike can be manufactured.

(4) Multiple gates can be set.

(5) The temｐarature can be maintained in the molten-metal transit cart.

4. Treatment of molten-metal

(1) Route of treatment

Melted in the crucible -> Transit cart (de-gas by spinning) -> Supplied thru the pipe in retention furnace ->Less oxide produced in the retention furance

（２）Sr, Ti-B are used.

5. Heat treatment system

This is an innovative development with our technology in a joint effort with a heat treatment manufacturer. (First in Japan)

(1) Shorter treatment time. 3hrs20mins. (1/3 of ordinary time)        (2) The treatment is transitted by a robot one by one.        (3) The temparature and time are correct by one-by-one trearment. Products have even quality.
