Strengthen GPO3(UPGM203) high precision machining parts for rail transit thickness 0-80mm
GPO3(UPGM203) material has good insulation performance, mechanical strength and good machinability. According to the use requirements of different structural parts, it can support special-shaped, processing thread, inlaid screw sleeve and other processing technologies
This GPO3(UPGM203)product is used in rail transit equipment, which
needs multi-faceted processing and deep hole processing. The
machining accuracy is very high. The tolerance of two Φ 30 round
holes is required (0, + 0036), and the concentricity of the two
round holes is required to be 0.15.
Our company has 10 raw material production lines, which can produce
materials of different panel sizes to reduce the loss of raw
materials. With more than 100 CNC processing equipment, nearly 30
technical engineer team, and perfect process control process, we
can ensure stable product quality and low production cost. At
present, we have become the leading manufacturer of ABB, Siemens,
Schneider and CRRC
Features of GPO-3 material :
Low smoke and halogen free meet EN45545/NF F16-101
In the glass fiber insulation board, the proportion is light,only 1.85-1.95g/cm3
Color can be customized
High strength and arc resistance up to 180 seconds
Dimensional stability
it meets of CTI600
Good flame and Low smoke
Good weatherability and strong anti-aging ability.
