Thread is widely required for machining investment castings. According to the assembling purpose, customer marked drawings of castings with thread standards. We need to machine the threads when investment castings finished. Currently, we machine the threads mainly by two processes. One is lathe thread process and the other is rolling thread process. To use which process should depend on the thread requirements.
Our steel castings produced by investment casting process can replace many steel fabricated parts.The process is ideal for multi piece fabrications using over 4mm thick steel sections that also need drilling or machining. Advantages of investment castings that replace steel fabricated parts:
Tongda has the ability and skills to deliver investment castings for oil and gas industry.We have been supplying quality investment castings to the oil and gas industry for more than 10 years.As these investment castings are used in high temperature and high working power,so they encounter hard working conditions(water,mud,crude,ect).By using investment casting technique,we could create near net shape or net shape parts with high performance and wear resistance.From quick sample inspection,large volume production,we could all meet your schedule needs on time.
With the development of automobile, machinery, aerospace, instrumentation and other industries,the application of aluminum die castings are gradually expanded.Meanwhile,aluminum die casting purchasers also put forward higher requirement on the surface quality.Now we would like to introduce shot blasting for aluminum die castings.
In modern society,agricultural machinery is becoming more and more important than before by development of science and technology .So some advanced agricultural machines like tractor,cultivator,chisel plow,subsoiler,air seeder,harvester,ect are made for production demands.However,most of the machines manufacture purchase parts from parts manufacturers.Thus Tongda often make investment castings for agricultural parts dealers or machine manufactures.
Welding repairing is widely used process for repairing investment castings.
