DESCRIPTION

Locomotive parts
　　
We have a well equipped forging and machining workshop to ensure the products supplied by us are with high standards.
　　
We have spectrographs, metallographic analyzers, hardness testers, ultrasonic test machines, magnetic particle flaw detectors, impact testers, tensile strength testers and other inspection instruments to strictly control the quality of our products.
　　
Brake block
　　
We also supply the Brake block for train and wagon , including cast iron brake block, high-phosphorous brake shoe, composite brake block.
　　
There’re two types of cast iron brake block, normal type and high phosphorous cast iron brake shoe. The difference lies in the content of the phosphorus. The P content in normal type is 0.7-1.0%, while in high phosphorous cast iron brake block, the P content is above 10%.
　　
The composite brake block is more widely used currently, due to its variety of advantages.
　　
The materials of composite brake block is asbestos free, it contains resins, elastomers, friction modifiers and mineral fibers reinforcing its structure. It contains no lead, zinc or any other toxic materials, it is environmental friendly, and causes no bad smell in friction.
　　
The wear of the composite material is very low. The advantage of this material is a stable coefficient of friction in variable atmospheric conditions and high thermal resistance.
　　
The composite brake block is particularly beneficial in those situations where cast iron brake block would cause a safety hazard. Spark free brake blocks are essential in oil refineries, chemical works and ordinance factories. The composite brake block has much to offer in the braking of passenger rail, minimizing braking shocks by its smooth action and permitting higher load factor.
　　
Suspension spring
　　
The suspension spring also in our product range. It is used in the bogie system. It is made by alloy spring steel, like 60Si2MnA, 60CrMnA, 51CrV4, 55CrSi, etc.
　　
By the way, leaf spring used for truck are also in our range. It also made by alloy spring steel.
　　
Casting and forging parts
　　
We also can supply other casting and forging parts for railway and locomotive, like the brake block holder, railway clamping clips, railway axle box, railway coupler, rail braces, heel blocks, switch stand casting, knuckle, yoke, follower block, knuckle pin, Bolster etc.
