Tianjin Xinlian Casting and Forging Co.， Ltd. is a joint-stock private enterprise with a registered capital of RMB 7.8 million yuan. As the main business item， it is producing ductile cast iron parts under 2 tons. Now， it has 110 employees， including 1 senior foundry engineer， 2 foundry engineers and 8 worker-technicians. With about 3D-year experience in producing common ductile iron， these personnel have quite great technical strength and developing ability. Its workshop covers an area of 10，000 sq. meters， with an annual productivity of 8，000 tons. The Company's basic business purpose is Clients Uppermost and Honesty First. The greatest goodness to clients and friends is to create customer-satisfied quality products. By years' research， and relying on the profound understanding of foundry industry as well as the meticulous production process and link design， the process flow has been improved， eliminating defects in the flow. The quality control system is working well and effectively. Because of the deep knowledge and rationalized use of materials to make impure elements in the molten iron much lower than that set forth in national standard， the product quality has been really assured. The Company has a full range of measuring means， from material incoming inspection， sample keeping for each furnace， pouring recording， parts marking management， dynamic management of middle parts storage to customer satisfaction， and， centered on these measures， a quality recording system has been created， enabling a valid quality retrospection for customers' total reliance

Main Material Categories:
1. Gray Iron: all produced with cupola to avoid to the minimum the possible C-type graphite occurrence in the gray iron due to the use of electric furnace， so as to ensure the brightness and compactness of machined surfaces of big and thick cast parts. Grade: HT150 - 300.
2. Common Ductile Iron: all produced out of quality pig iron and scrap steel with electric furnace. It is the Company's strong suit gained from 30-years' research and experience. Grade: QT400 - 700.
3. The National Standard QT400-18L (EN-GJS-400-18LT) was successfully developed at the end of 2008 for a type of side bearing body used in 1.5MW wind power generation.
4. Austemper Ductile Iron (ADI): a prime material produced by our Comapny， mainly used for making planet reducer's planet gear ring， planet gear shaft， segments of gear 2M to 6M in dia.， with a weight varying from 30 to 800kg. The material is compliant to European Standard巨N1564: in 1997， Grades EN-GJS-1000-5， EN-GJS-900-8， and DCQT900-8 for Austemper Ductile Iron as seen in the document submitted on July 10， 2008 for approval as National Standard of China. These two kinds of materials are much better than common ductile iron and low alloy steel in all-round performance. They have broad prospects of use due to higher ducitility， excellent shock-absorbing ability and abrasion resistant quality.
5. Alloy Cast Iron: featuring heat resistance and corrosion resistance， used to make parts for Tianjin Toyota Motor， and also make reaction vessel and mixing shaft of alloy ductile iron.
