1 blow bar, 2SGS Certificate, 3Proper H.T.and Hardness, 4Durable and stable performance, 5OEM - details see: https://www.machineto.com/blow-bar-10316930

AMaterial Specifications:

The blow bar material depends on what kind of raw material the impact machine crush. The material ranges from High manganese , high chrome, composite material with ceramic to the other customized material. the High chrome is the optimized material for blow bar.

Tips:The high lightened material code is popular material for high Chorme blow bar.

BProduct patterns:

3 basica types of patterns are available.They are wooden pattern, Lost foam pattern, the aluminum pattern. The blow bar prefers the wooden and aluminum pattern.

To coat chemicals on the surface of the blow bar:

C Manufacturing Process:

1 Pouring the molten Iron water into the patterns:

2 The know-how H.T. (The temperature and time are controlled

by the computer)

3 To machining the casting (High chrome or High manganese)

if there is requirements on the products drawings.

The milling machine to machining surface

4 Grinding the casting surface:

5 Quality inspections

(Dimensional inspection, Hardness inspection, mettallographic structure etc.)

Dimensional inspections with caliper.

6 Hardness inspection with the HRC meter.
