EPG has been successfully certified by ISO9002 Quality Management System, ISO9001 Quality Management System, API certificate, ISO/TS16949:2002 and ISO10012 measurement management system.
Higher operating temperatures can gradually “cure” and harden seal lips, making them lose the flexibility necessary to seal effectively.

Application:
The products can be widely used in the area of cement mill,rotary kiln,shipbuilding,
metallurgy,mine,sugar mill,powder plant,rail road,engine bed and so on.
We can provide OEM service for cement mill and rotary kiln casting parts,marine steel castiThe PTO shaft included with all Victory Tractor mowers has a longer extension than the typical PTO Shaft. The added length is necessary because of the far reaching movement of the mowers to the right of the tractor. ng parts,sugar mill machinery parts with carbon steel or low alloy steel.

Possible defects:
|
Defect |
Causes |
|
Unfilled sections |
Insufficient material Low pouring temperature |
|
Porosity |
Melt temperature is too high Non-uniform cooling rate Sand has low permeability |
|
Hot tearing |
Non-uniform cooling rate |
|
Surface projections |
Erosion of sand mold interior A crack in the sand mold Mold halves shift |
There are no these problems for us.
Uniform wall thickness will ensure uniform cooling and reduce defects. A thick section, often referred to as a hot spot, causes uneven cooling and can result in shrinkage, porosity, or cracking.
Corners
Round corners to reduce stress concentrations and fracture
Inner radius should be at least the thickness of the walls
Machining allowance
Add 0.0625 – 0.25 in. (0.16 – 0.64 mm) to part dimensions to allow for machining to obtain a smooth surface.
