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.

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.

The most noteworthy events in the petroleum and chemical industry in 2004
On the 6th of this month, Showa Shell Petroleum officially imported crude oil from Iraq. January imports increased to 113 million barrels. On January 29, the Russian government raised the oil export tax. The Russian government signed a decision on raising the export tax on crude oil. From February 1, 2004, the export tax on Russian crude oil was increased from the original 31.2 US dollars per ton to 33.9 US dollars per ton, and the export tax on petroleum products was reduced from the original per ton. 28.1 U.S. dollars increased to 30.5 U.S. dollars. On February 10th, OPEC announced that it will cut its daily output by 1 million barrels from April 1st, in order to curb price declines. The decision reduced OPEC daily output to 23.5 million barrels since April. On March 7, Saudi Arabia signed agreements with oil companies in Russia, China, Spain, and Italy to allow oil companies in these countries to explore and produce natural gas in the vast deserts of Saudi Arabia. On March 31st, the prices of refined oil in various provinces and cities nationwide were raised: gasoline was raised by 300 yuan/ton, and aviation coal was increased by 390 yuan/ton. This is the 11th time that China’s refined oil products have been raised since 2002. On May 7th, in New York's commodity futures trading market, the price of crude oil in June suddenly surged, breaking the psychological threshold of 40 US dollars per barrel, and creating the highest price in nearly 13 years. On May 19, according to the National Development and Reform Commission's notice on adjustment of refined oil prices, refined oil prices in various provinces and cities across the country were raised again. Among them, diesel No. 0 rose from 3.06 yuan/liter to 3.23 yuan/liter, and the increase rate was about 6%, which was a relatively large adjustment in recent years. On June 3, the ministers of OPEC agreed to increase oil production quotas. From July 1st, the quota for the production of crude oil will be increased by 2 million barrels per day, and the output cap will increase by 500,000 barrels from August 1. The increase is smaller than market expectations. On June 30, the Minister of Industry and Energy of Russia Khristenko stated in Moscow that the two projects have not been approved by the Russian authorities on the Anhang Line of the oil pipeline project leading to China and the Anna Line previously proposed by Japan. On August 25, China's first energy futures contract, the fuel oil futures contract, was officially listed on the Shanghai Futures Exchange. It has become the first type of futures trading that has been approved for listing since the Chinese futures market was rectified and reorganized. On August 26th, after the National Development and Reform Commission issued a notice, the domestic refined oil price rose in an all-round way. The price adjustment was the third time this year. On August 30, due to the successive attacks on oil pipelines, oil exports from southern Iraq have completely stopped. On August 30, Mexican state oil company announced that the company recently discovered large reserves of seabed oil in the Gulf of Mexico. The conservative estimate is 54 billion barrels, which will increase the country’s oil reserves from the current 48 billion barrels to 102 billion barrels. . This discovery made Mexico one of the countries with the world's largest oil reserves; its daily average production of crude oil will increase from the current 4 million barrels to 7 million barrels, second only to Saudi Arabia and Russia. On September 14, Russian President Vladimir Putin approved the government’s proposal to replace the assets of Rosneft with the shares of Natural Gas Industries AG. This means that Rosneft will be merged into a subsidiary by Gas Industry, and it will also announce the world’s The largest energy company is about to be born in Russia. On September 23, the U.S. federal government stated that it plans to use part of the strategic reserve oil to ease the oil shortage caused by the hurricane Ivan attack. On September 25, after setting a high price of US$48.88 per barrel on the 24th, the US government began to use 1.7 million barrels of strategic reserve oil to stabilize the price of oil from the 25th. On September 27, the price of the New York crude oil futures market hit its highest price in 21 years: The price of oil rose by 36 cents to 50 dollars per barrel. On September 29, the Atasu-Alashankou section of the China-Kazakhstan oil pipeline linking western Kazakhstan and Xinjiang, China, officially broke ground. On October 18th, natural gas, the largest gas source of the West-East Gas Transmission Project, from the Aksu Kela 2 well of Xinjiang reached Baihe Town, Qingpu, Shanghai. This section of the west from Xinjiang Aksu, Baihe Town, Shanghai to the east, a total length of 4,000 kilometers of the energy artery has been really achieved across the board. On October 18th, under the circumstances that global oil production continued to fluctuate and demand for oil increased, international crude oil prices exceeded the price of 55 US dollars per barrel. On November 16th, Chongqing Zhongxian Natural Gas Pipeline officially realized gas transmission operation. This is the first time since the development of the oil and gas fields in the Sichuan-Yunnan region that natural gas was transported through pipelines.
