The sand casting process is a casting method in which sand is used as a main molding material to prepare a mold. Sand casting is the most traditional casting method. Due to the characteristics of sand casting (not limited by the shape, size and alloy type, short production cycle and low cost), sand casting is […]

Molds are various molds and tools used in industrial production for injection molding, blow molding, extrusion, die casting or forging, smelting, stamping, etc. to obtain the desired products. In short, a mold is a tool for making a shaped article, and the tool is composed of various parts, and different molds are composed of different […]

With the rise of lost foam casting, how to reduce the cost of castings, increase the yield and improve the quality is a problem. To solve such problems, the key is in the choice of sand type. Usually, in order to reduce the cost of sand, people will choose cheap quartz sand. However, due to […]

Through the application of the lost foam and solid casting, the paper sprue tube does not produce an endothermic reaction or a gasification and cooling of the foaming runner at the beginning of the molten metal casting like the ceramic tube. Because of its good thermal insulation performance, the paper sprue tube reduces the heat […]

The solid sand casting process has its unique advantages. There is no drafting angle and there is no model parting surface. It can not only save the cost of making wooden models for the production of single or small batches of machine bed, base and other castings. Moreover, it has the advantages of good surface […]


The body of the lost foam mold is made of forged aluminum or cast aluminum. It is used in alternating hot and cold water environments. Different maintenance methods are required depending on the mold structure. First, the maintenance of manual disassembly mold Before using the mold, check the following items. 1. Whether the filling port […]


In mold making, we usually hear casting and forging. What is the difference between the two manufacturing processes? Casting is only used for large forgings. Casting is an as-cast structure with large columnar crystals and loose centers. Therefore, it is necessary to break the columnar crystal into fine crystal grains by large plastic deformation, and […]

Casting is the process of casting a liquid metal into a casting cavity that conforms to the shape of the part. After cooling and solidifying, a forming method of the metal part blank having a certain shape, size and performance is obtained. Casting is mainly divided into sand casting, low pressure casting, centrifugal casting, metal […]

In the production process of lost foam, model manufacturing is an important link. The selection of EPS raw materials, the accuracy of model processing, the density of the model, and the thermal decomposition products during casting all have important influences on obtaining high-quality castings. 1) Model manufacturing At present, the common mold making methods are […]
