Simply put, it is a tool for making shaped articles. It can make a variety of different items and some parts, and the mold has the […]

How to maintain metal casting mold

Metal casting mold is one of the molds often used in cast aluminum plants. It is characterized by small casting tolerances, high efficiency, and beautiful surface of metal castings. Generally, after the acceptance, in order to maintain the performance state and the service life of the mold, the normal production and the quality of the […]

Sand casting meaning

Sand casting refers to a casting method for producing castings in a sand mold. Because the molding materials used in sand casting are cheap and easy to obtain, the castings are easy to manufacture, and can be adapted to the single-piece production, batch production and mass production of castings. For a long time, it has […]

What are the sand casting processes?

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 […]

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 […]

Advantages and effects of paper sprue tube in solid sand casting

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 […]

Application of paper sprue tube in real casting of resin sand

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 […]

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 […]

What is the difference between a casting mold and a forging mold?

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 […]
