Precision casting, resin is a natural resin, the fundamental factor is a variety of isomeric resin acid mixture, the higher the content of resin acid, the more basic. This kind of mould material is dissolved in water or acid, can be poured at higher temperature forming, practical for a small amount of mold. In addition to the appearance of the mold (wax), there are runner wax, bonding wax, repair wax, dip wax and so on. Liquid powder, water and gas are all used as aggregates. Some solid powders, such as some acids, polyols, bisphenol compounds and thermosetting resins, are commonly used. Aggregates with an exit quality fraction of 20% ~ 40% constitute aggregate molding materials.

The following precision casting processing manufacturers will introduce you to the precision casting mold materials:

1. Wax-based molding material: it is a kind of molding material with mineral wax or animal wax as secondary factors, which is widely used in the world. The most widely used in precision casting is paraffin palmitic acid molding material.

2. Resin base material: resin error quality data, its reduction, high strength, sticky and brittle, fragile. The aggregate mold material recycling application is definitely difficult, is advantageous to increase the profit.

3. Aggregate molding material: in order to reduce the swelling of the molding material, prevent the deformation and nominal shrinkage of the molding material, improve the nominal quality and precision of the investment molding material, the oracle bone is being added to the molding material to form the aggregate molding material.

4. Water-soluble molding material: some simple cavity core is being consumed and there is no need to heat a mold air. In order to improve the function of resin rarely set or modified turpentine, it is to solve the turpentine by chemical, so that the number of its members increased, reduced double bond, in order to improve the chemical stability, increase the acid value.

5. Series of goods molds: manufacturing precision and size of the same with the melting die smelting, for the mold function requirements are not the same.
