- Is it a shape? I hope that it is possible to maintain the 0 strength of the Ame of female sand particles at a low price and regenerate it and use it again! Yes. The method of regenerating and adding caking 011 immediately after use shows the best results. The aV process and the freezing νI type jar are used as methods to meet this requirement.
This gives the roughness of the working mold l/c. The latter method uses water (/J79-Merui eJ when wet (/J
It gives a little toughness and makes C/J operation easier by 1 minute when cutting the die.
A method of adding strength to the mold by adding bentonite or # powder, kneading, and molding with a sand mixture, and then freezing low-dry water within the mold CLJ temperature range of -1°C to 269°C. Ru.

Although the second TlAl system does not require RT, there are many restrictions on maintaining the temperature of the a mold υ for casting. In other words, there is concern that part of the temperature will melt and the temperature will drop to 991 degrees.

る。In contrast to the conventional method of making a sweetfish type shield in which water as a binder is frozen at temperatures below 0°C, the present invention uses frozen sweetfish at a temperature close to the freezing temperature. Therefore, sand preparation, molding, etc., are performed using methods similar to freezing molds, and since the freezing temperature is around room temperature, the mold can be made to emit light even if the temperature is low. 1ζ＠＠JD Even if you cool it down enough and leave it there while it is popular, it will melt and the time in 1 will be short.If it is 1ζ@iJD, it is easy to handle the mold υ or two.

] and the V that was mixed up was put into a refrigerated car at about 20°C for 62 hours, and the mold was taken out.The melting temperature of the oleic acid bath was 14°C. ^
So water? It is easier to freeze than the 1ζ base when used, and in addition, in the Kenpo of Renku Shun, the mold (Koshi) was made with raw sand in the Llj Sakubashi L2, and the casting that was left in the chest with a centimeter was found to have defects. The casting surface was also of good quality. The disintegration properties of the Koshi were also good.
