How to make the Rail Shoulder? – Lost Foam Technology

Lost Foam is a unique casting process which is ideally suited to the manufacturing  of  geometrically  complex  parts  with  one  cast.  The main  characteristic of the process – as already stated in  the name “Lost Foam” – is the use of “lost” patterns made of organic foam materials. The patterns are inserted into a mould material that is free of bonding agents by using vibration compression. During casting, the pattern is then pyrolysed by the molten steel, thereby creating a hollow space which the molten steel fills up. In this way, an exact metallic cast copy of the pattern is created. In addition to the possible geometric complexity, Lost Foam cast parts distinguish themselves through their excellent surface qualities and dimensional accuracy.

Lost Foam Procedure


Process 1: Pattern Creation


Process 2: Pattern Clustering


Process 3: Coating


Process 4: Drying


Process 5: Compaction


Process 6: Casting Molten Metal


Process 7: Cooling And Extraction


Process 8: Separation


Process 9: Shot Blasting And Fettling

Rail Clip Production

We have 4 automatic clip production lines with robot hands, which have the production volume for 60,000 pieces clips per day.
Advantages for robot hands production:

– Guarantee the dimensions stability
– Increase the quality
– Maximum the production volume
– Reduce labor cost

Hot/Cold Forging

With the advanced forging production lines, we are able to produce screw spikes, rail bolts, rail clamp, rail anchor, and all other forged products.

Our advantages:

– Advanced production equipment, mature production technology and perfect quality assurance system.
– High production volume, able to produce with the fastest speed.
– Mature management system with lowest cost, which guarantee the quality stability.
– Competitive price with best service.

Lost Foam Casting

We use lost foam casting process, the advantages as below:

– Without Limits.Lost Foam enables geometrically complex cast parts to be created with the highest quality.
– Dimensionally exact. – High dimensional accuracy and low tolerances.
– Better Surface. Surface smooth and less flaws.
– Without subsequent machining. Lost Foam is done without a core and without burrs so that there is almost no subsequent fettling work.
– Weight reducing. Lost foam enables the creation of thin-walled, filigree cast product.
– Environmentally friendly. Energy efficient casting process with low emissions and closed mould material circulation.
