|
Cutting
of Precise sizing of steel bars as per requirement for the forging |
|
|
|
Friction Welding
Bi-metallic (magnetic, nonmagnetic) materials are welded on special purpose friction welding machines for exhaust valves only to achieve different hardness to work under extreme condition |
| |
|
|
|
|
|
|
|
|
Upsetting
electrically upsetting machines equipped with pressure and temperature controls maintains consistent flow of material that helps in forging with out changing the material composition. |
|
|
|
Forging
High speed precision presses are used for accurate and high productions. |
| |
|
|
|
|
|
|
|
|
Stellite Welding Operation
A Cord of Special Satellite material is placed into the valve seat with special satellite welding process to improve the corrosion and high temperature wear resistance mainly in exhaust valve. |
|
|
|
Normalizing
Electric furnaces are used to achieve a martens-tic structure of valves that releases stress developed during forging |
| |
|
|
|
|
|
|
|
|
CNC Machining
CNC lathe and Special purpose CNC machines are used to meet precise dimensions which decrease the prototyping and production cycles. |
|
|
|
Surface Treatment
A layer of hard chromium or Tufftrided /Nitride or other surface treatment is done as per the application and requiem. |
| |
|
|
|
|
|
|
|
|
Grinding
Special Grinding machines for seat and centrals grinding machine for steam are developed for maintaining the accurate dimensions of an engine valve. |
|
|
|
Final Inspection
Strict quality inspection is also performed in high-tech laboratory under highly-qualified engineers for quality assurance. |
| |
|
|
|
|
|
|
Packing
100% inspection builds confidence amongst packing staff to pack quality at valve in special packing materials |
