Warner Gear’s 4WD locking hub takes advantage of ZA-8’s net shape castability, creep resistance, and excellent finishing characteristics to provide a highly functional and aesthetic cover. ZA-8 alloy was chosen because it handles temperatures close to 200 degrees F, a...

Lockable Door Knob – Model 930

View

The main feature of this lock design is that the handle is cast with a cylindrical shaped wall, but it is then post formed to a spherical shape. If the Alloy 3 used for this casting did not have high ductility, the final shape could not be achieved and the pressure...

Link Between Aluminium Structural Beam

View

The aluminium structural beam must strongly fostered with water proofing to avoid penetration from the rain or washing water. The geometric position must be sound, and operating live must be assured.

Lead Screw
