Train Parts Casting is one branch of carbon steel precision casting, which is widely used in train markets. Precision Casting Of Train Parts adopts lost wax casting, also called investment casting. In wax pattern process,we mix stearic acid and paraffin wax.
In wax pattern making, as you know, it is better than polyethylene, and the wax deformation is small. In dipping slurry process,most of the suppliers adopt water glass technics in domestic area,but we adopt compound technics or silica sol technics. As you know, carbon steel castings will be much smoother with compound technics (compound of water glass and silica sol technics),this method is so popular with our customers, and the quality is higher than water glass technics, the cost is lower than silica sol technics.
In shell making,we adopt automatic sand-covering production line, which was invented under the guidance of our general manager.The indoor temperature was controlled by air-conditions,keeping the temperature at 24℃±1℃, which can make the castings much more stable,the internal tissues much more well-proportioned.
Our train parts as precision casting products have quality assurance in accordance with ISO9001: 2008, strict material inspection and exact dimension control, with 100% quality control. OEM order is welcome. The parts can be made completely based on your specifications such as drawing, design, sample etc.

Greentech International (Zhangqiu) Co., Ltd is the professional side channel blower supplier.
Our revolutionary G_400 blower can create pressure difference of up to 1000mbar-more than any other gas ring pump. So far, the systems used to reach these differential pressure ranges were much louder and larger-or subject to wear. Now the advantage of wearfree operation cupled with a low noise level can also be used in most demanding applications.
The G_400 series side channel vacuum pump/compressor can work up to 20, 000 hours without maintenance down time.
These specialist machines have proven their reliability under the harshest of conditions.
Their noise level was already impressively low, but our engineers and designers are able to make them even more quiet.
Features:
1. Beautiful surface
2. Easy installation
3. Low noise level
4. No vibration, and therefore complete dynamic stability
5. Pulsation-free discharge
6. Minimal maintenance
7. Higher pressure ratio
8. Cooler running bearings
