After several months of trial operation and rigorous testing, the first phase of the Chongqing Changan Automobile Test Site recently passed the acceptance test, marking the full operation of the first comprehensive automobile test site in the western region.
Chongqing Changan Automobile Test Site is located in Huangsha Township, Dianjiang County, Chongqing. It has a total investment of 1.31 billion yuan and covers an area of ​​2.5 square kilometers. It includes 13 main roads, 4 entrance bridges and nearly 70 special roads. It is the fifth in China. The first professional car comprehensive test site in the western region that meets national standards. The test site is currently the largest dynamic test site in China. It has the only wet-sliding stability road and wet-slip dynamic square in China, and has 30 kinds of reliability test roads that can be freely combined and comprehensive evaluation roads with more than 20 road conditions.
Investment Casting can make use of most metals, most commonly using steel alloys, carbon steel,stainless steel, and tool steel. This process is beneficial for casting metals with high melting temperatures that can not be molded in plaster or metal. Parts that are typically made by investment casting include those with complex geometry such as turbine blades or firearm components. High temperature applications are also common, which includes parts for the automotive, aircraft, and military industries.
Our products cover a wide range of industries including train & Railway, automobile & Truck, construction machinery, mining machinery, forklift, agricultural machinery, shipbuilding, petroleum machinery, construction, valve and pumps, electric machine, hardware, power equipment and so on. We are capable to produce products according to customers' drawings or samples, we focus on both carbon steel and alloy steel. Up to today, more than 100 raw materials and 5, 000 kinds of different products have been developed and produced by us. We are familiar with the material standards of many countries, such as Chinese GB, American ASTM, AISI, German DIN, French NF, Japanese JIS, British BS, Australian AS and Association of American Railroads (AAR ) and other industrial standards.
The process is generally used for small castings, but has produced complete aircraft door frames, steel castings of up to 3 tons and aluminium castings of up to 100 kg. It is generally more expensive per unit than Die Casting or sand casting but with lower equipment cost. It can produce complicated shapes that would be difficult or impossible with die casting, yet like that process, it requires little surface finishing and only minor machining.
Investment casting is used in the aerospace and power generation industries to produce turbine blades with complex shapes or cooling systems. Blades produced by investment casting can include single-crystal (SX), directionally solidified (DS), or conventional equiaxed blades. It is also widely used by firearms manufacturers to fabricate firearm receivers, triggers, hammers, and other precision parts at low cost. Other industries that use standard investment-cast parts include military, medical, commercial and automotive.
Investment casting offers high production rates, particularly for small or highly complex components, and extremely good surface finish (CT4-CT6 class accuracy and Ra1.6-6.3 surface roughness) with very little machining. The drawbacks include the specialized equipment, costly refractories and binders, many operations to make a mold, and occasional minute defects.
