China's large professional manufacturer of Precision casting, the main essence of Railway Parts Castings, carbon steel railway parts castings, Alloy Steel Castings, using investment casting, precision casting, lost wax casting , including crank connecting rod mechanism, the body of the rail accessories and cylinder head, with gas institutions, fuel supply system, lubrication system, cooling system, starting device and so on, a lot of parts are useful to the investment casting, investment casting visible widely used widely in the field of the train.

 

Jun long precision casting co., LTD., the main products are Precision Casting Of Carbon Steel, Low carbon steel , medium carbon steel castings, high carbon steel, Alloy Steel Precision Casting, high manganese steel, high chromium steel, high nickel steel, a variety of materials such as precision casting products .The parts are mainly used in Precision Casting Of Auto Parts, forklift parts casting, precision casing of ship parts, Precision Casting Of Train Parts, mechanical engineering, petroleum machinery, mining machinery .Our products has been exported to more than 20 countries and regions in the world. Our company has cooperated with our customers with the business philosophy of integrity, pragmatism, professionalism and innovation, and won the unanimous praise of our customers

 

The company covers an area of 30,000 square meters, with more than 200 employees, 10 r&d personnel and 12 quality control personnel. There are three production lines, two composite process (i.e. silica sol + water glass), and one silica sol process. The annual output reaches 8000 tons, the enterprise has passed iso9001:2005 quality management system certification, and passed the national environmental protection department approval, has the formal environmental assessment certificate, is a household name of the green casting enterprise

 

All the assembly lines in the workshop are made by our general manager according to practical experience. The product quality can be guaranteed while greatly improving the work efficiency and reducing the workload for the workers. By the end of 2015, all the workshops of our company have been automated production .For example, automatic wax injection machine, automatic silicon sol process robot, automatic silicon sol process wind main line, automatic water glass process assembly line and curing pool, automatic pouring. Because they are all automated production, the quality of the shell is guaranteed in the early stage,Precision casting products with weight from 0.1KG to 500KG can be completed .Products with wall thickness as low as 3mm. Products with complex shapes.The defects of porosity, sand hole, slag inclusion, cold insulation, shrinkage and other casting defects are effectively avoided

 

Are main products of our company adopted complex process (silica sol + water glass), adopt the low temperature wax, four shell layer using silica sol process, three layer using water glass process, composite process to produce a product that no matter from the surface finish, and internal quality and silicon sol process almost the same, the price is cheaper than silicon sol process a lot, and water glass price though it's cheap, but the product is very rough, and composite technology products of good quality and low prices, the most suitable for large batch of products, can guarantee the quality of customer requirements, and can guarantee a reasonable profit space, so, Our foreign customers have been cooperating with us for 8 years, and we have cooperated very well.

Inspection: our company has special physical and chemical laboratory, with perfect inspection equipment (spectrometer, three coordinate measuring machine, metallographic analyzer, impact test machine, tensile testing machine, hardness tester, magnetic particle inspection machine, ultrasonic testing, etc.), can satisfy the customer different product requirements, and issue a corresponding test report

 

Processing: we have two horizontal machining center, CNC machining center, bench drill, vertical drilling machine, rocker arm drilling machine, milling machine, grinder, planer, CNC lathes and other all-round machining equipment
