The traditional type of precious metal casting process is difficult to avoid encountering such problems: the raw material will air oxidation, breakage, sand holes, lack of surface gloss, internal structure caused by porosity, etc..

In order to better deal with such problems, it is important to understand the reasons for vacuum casting this situation.

The raw material is not evenly heated during the whole process of melting, and there is no selection of degassing, thus a lot of air is sucked into the melted raw material to cause pores (pores are divided into precipitation pores, invasive pores, reflective pores, here is not an exhaustive description, you can check the wikipedia);

The mold is not heated, the mold surface should be heated to 150℃-200℃;

Too much film release agent spray, applying too much film release agent will form a lot of vapor in the whole process of casting;

During the whole process of pouring, quantitative analysis of pouring is not selected. Subsequently, the pouring rate is too fast, which will cause the condition of casting rupture.

Unfortunately, these situations are inevitable in the traditional casting process. Each process of casting must be manipulated by experienced teachers to ensure a good quality product. Is there an easy way to deal with all kinds of conditions in the whole process of casting?

The vacuum pump continuous casting has smelting and casting role with one. Just put in the raw materials you want, you can easily cast high density gold, k gold, silver, copper, tube, stainless steel bar, hollow tube, etc..

Equipped with fully automatic stirring device to ensure the balance of items.

At the same time, the choice of vacuum pump working pressure and rare gas protection equipment, so that the surface of the goods bright, no air holes, no air oxidation, to minimize the depletion.

Through easy learning and training, operators can use several machines and equipment, and can easily make a variety of castings with the appearance you wish by simply removing and changing the molds.

The basic principle of vacuum pump rolling

Continuous casting is a superior casting method in which the molten alloy is continuously poured into a unique mold called a continuous casting crystallizer, and the solidified casting is continuously pulled from the other end of the mold, and the casting can be as long or short as you want it to be.
