1.All steel needles are made of high grade carbon steel, after quenching treatment.
2.Special high quality steel pins for longer pin lifespan.
3.Each needle surface smooth,no less of fiber and pierce is very well.
4.China and the world's leading textile machinery manufacturers(Trutzschler, Rieter)in the use of our product.
5.Can be developed according to customer requirements and development of special steel.

1.Extruded aluminum profile instead of aluminum castings
2.Compare with aluminum castings, extruded aluminum profile has the following advantages:
A.Can withstand the higher tensile strength
B.Better dimensional stability
C.More beautiful to look at

Advantages of aluminum alloy castings:
1.Good casting properties,in favor of casting thin-wall and complex castings;
2.Beautiful to look at, have good surface gloss;
3.Lightweight,under the same loading conditions using aluminum alloy castings,can reduce the weight of the structure;
4.Good corrosion resistance in air and water;
5.Advantages of aluminum alloy castings make it become one of the most popular products for customers.
