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.
With advanced injection machines, we are able to offer:
– Angle plate or rail insulator
– Rail pad
– Plastic dowel
– Other products according to customer’s needs
We are able to do various surface treatment with the most advanced technology. All the surface treatment is eco-friendly and finished in our own factory.
– Electrostatic spraying for rail clips. Anti-corrosion for 2 years.
