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 […]

In the lost foam casting, the foam coated with refractory coating is placed in a sand box, and the surrounding of the pattern is filled with dry sand. The microseismic and negative pressure are used to compact the liquid metal without casting the core, in the casting and A new casting process that continues to […]

1) Optimized control of raw materials The raw materials required for lost foam casting production are roughly divided into model raw materials, dry sand raw materials, coating raw materials, and alloy melting raw materials. Since the lost foam casting process is a system engineering, the selection of raw materials is particularly important. Therefore, controlling the quality […]

Almost all the introductions about lost-foam casting coatings will narrowly describe the “coating permeability” of lost-foam casting coatings as “breathability”. In production practice, we can understand that the paint after casting changes color. This is because the free carbon produced by the violent combustion of the foam model in the cavity passes through the coating, […]

Conventional casting sand is shaped by an adhesive to form a cavity. After contacting the high-temperature metal liquid, the binder and other auxiliary materials will instantaneously generate high-pressure gas, fill the sand gap and form a gas film between the liquid metal and the cavity wall to block the liquid metal from entering the molding […]
