How can precision stamping parts processing plants ensure the stabilization of casting geometric dimensions?

Many precision stamping parts processing plants use vibration stress to reduce the as-cast stress of the casting or change the state of the as-cast stress to complete the stabilization of the casting geometric scale. What are the specific requirements for mold management?

1. Vibration aging is a mechanical method to generate a resonance frequency for the castings to be treated. Vibration stress is used to reduce the cast stress or modify the cast stress to achieve the stability of the casting geometric scale. Compared with thermal aging, vibration aging has the following advantages:

Thermal aging requires a large annealing furnace with messy equipment and a large production area. The equipment required for vibration aging is simple, easy to operate, small footprint, can be handled anywhere, and the size of the workpiece is not constrained. Thermal aging requires a lot of fuel. Vibration aging requires very little energy. It is said that a one-horsepower mechanical vibrator can handle castings of more than 50 tons.

2. When vibrating aging castings, polyurethane spacers are required at the bottom of the casting.

3. 4 pads within 3 meters of the casting. Precision stamping parts processing plants should pay attention to castings larger than 3 meters and place 6 pads evenly.

4. For small molds within 4 meters, the vibration time is 40 minutes. Castings larger than 4 meters need to vibrate on both sides, and the vibration time on each side is 40 minutes.
