ISMT manufactures special smooth bore tubes for piston pins. These tubes are cold drawn with a mirror finish on the ID so as to achieve a Ra value of as low as 0.5. Piston pins made from seamless tubes offer a cost effective alternative to piston pins made either by forging or by machining solid bar stock.
We are approved for the supply of air-bag canister tubes by four of the largest suppliers of air-bags globally. ISMT has developed special fine grain steels as well as tube finishing processes to obtain extremely high burst pressure values at low temperatures.
Hollow stabilizer bars made from seamless tubes are lighter than their traditional solid counterparts and as a result these are increasing in popularity. ISMT is an established supplier of seamless tubes to some of the largest manufacturers of stabilizer bars globally. We have worked closely with our customers to develop special grades of steels that are cost effective and yet meet the high fatigue failure norms required of these tubes.
Profile Tubes for Steering Columns:
We manufacture cold drawn tubes with special sections such as oval or triangular for collapsible steering columns. These tubes enjoy extremely tight cross sectional tolerances so as to transmit torque without any perceptible play between the sliding members.
Hollow bars are very thick seamless tubes that can be used as machining stock instead of solid bar. They offer a cost effective alternative for the manufacture of various turned components used in the automotive industry. ISMT can supply Hollow Bars in standard or customized grades of steel.
ISMT uses a combination of cold ring rolling (on Bad Deuben Machines) and machining to produce a variety of annular components such as gear changing shifter sleeves and dog clutches (for synchromesh gear boxes ), cages for constant velocity (CV) joints, pulleys, etc.
Swaged and Machined Axle Casings
ISMT specializes in the manufacture of tubular axle casings duly machined and fitted with a flange, saddle and brackets. These items can also be supplied in an intermediate stage i.e., as a formed (swaged) axle blank or as a formed and CNC machined axle blank.
Machined Gear Blanks
ISMT supplies CNC turned gear blanks in case carburising, direct hardening or nitriding steels with any desired profile and in a form that is ready for broaching, hobbing, shaving, or other finishing processes.
