Precision casting wax with good stability

Release date:2019-06-06 00:00 source:http://en.sofoi.cn Click:

Dalian precision casting wax is the material used to infuse oral tissue positive mold by oral impression mold. Including: (1) working model material: it is used to make working models and subtypes of prosthetics and orthotics, commonly used are gypsum, artificial stone, low fusion alloy, electroplating subtype material and epoxy resin subtype material


秒速时时彩The rubber protective wax is mainly divided into two kinds: ordinary paraffin wax and microcrystalline paraffin wax. Paraffin wax is prepared by solvent refining, solvent dewaxing and deoiling, refining, molding and packaging. Paraffin wax is divided into soap wax, crude wax, semi-refined wax and fully refined wax, each type is divided into a variety of grades according to the height of melting point, commonly used have 54 and 58 two kinds of paraffin.


秒速时时彩Precision castings have been widely used in all industrial sectors including aviation and weapons sectors, especially in electronics, petroleum, chemical, transportation, light industry, textile, pharmaceutical, medical equipment, pumps and valve components. Investment precision casting is a kind of casting process with little or no cutting, which can produce castings with high dimensional accuracy, low surface roughness, high flexibility and strong adaptability, especially for parts with complex casting shapes.


The moulds produced by precision casting wax are characterized by good stability, low shrinkage, smooth surface, high strength and good formability. The types of moulds produced abroad include filler moulds and non-filler moulds, which are subdivided into model waxes, repair waxes, emulsifiable waxes, gate waxes, and bonding waxes for embedding and sealing.


The annealing treatment of precision casting can heat the aluminum alloy castings to a certain high temperature, hold the temperature for a period of time, and then with the furnace cooling process is called annealing. Annealing process can eliminate the internal stress of casting, stabilize the size of casting, and ensure less deformation of casting. This increases the plasticity of the casting. This process is very important for casting. Without this process, the casting cannot be improved and the working efficiency cannot be improved very well.
