Precision casting wax is the general name of precise casting process obtained by precise modeling method. Is to use precision casting precision casting method for metal forming objects, namely the good liquid metal smelting, casting, injection, inhaled or other casting method into the prepared mold, waited for after cooling, the resulting objects of a certain shape, size and performance.
Precision in addition to the traditional precision lost wax casting production, to expand the service areas, specially set up the finished product manufacture department specialized in developing a new special tools and accessories, the product has good practicability and originality, tool wrench S2 top grade tool steel material selection, combined with the original lost wax casting technology to produce high strength alloy steel cutting tool chain head, tool body is made of aluminum alloy materials after CNC machining and anodizing color variety, to choose from.
Increasing the wax injection pressure can eliminate the corrugation and streamline on the wax surface. Bubble problems may arise when the wax pattern or when the wax to the wax models when velocity is too fast and turbulence and bubble, this phenomenon can be transported by reducing speed and increase the wax pattern diameter to solve. The shrinkage rate of the relevant line is often determined by the injection wax temperature and pressure, intermittent and mold temperature, so as to reduce the linear shrinkage rate: increase the injection wax pressure. Confirm whether the mold meets the required temperature. Increase the cycle time of wax injection. Increase the diameter of wax injection hole.
But compared with foreign countries, the varieties and quality of rubber protective wax in China still need to be developed and improved. Famous foreign manufacturers of rubber protective wax include Rhine company, ASTOR company and ENICHEM company. Lane has done a lot of basic research,
Depending on the number of carbon atoms in paraffin wax to the rubber surface migration velocity under different temperature conditions, the designed at 0,5,25,35,40 and s0 ℃ using temperature ozone resistant varieties of rubber protective wax. The former Soviet union has successfully developed modified rubber protective wax, which has excellent performance and can reduce the dosage of chemical anti-aging agents.
