Benefits of technology

The present inventor has developed an improved method for controllably holding or transferring objects during processing such as welds on steel plates used in manufacturing processes. This allows for better control over how these items are processed while maintaining their quality level.

Problems solved by technology

This patents describes various technical problem addressed in this patented text relating to improving the concave shape precision of metal objects being processed through conventional methods like hot water immersion copper plates. Existing techniques have limitations including uneven heat distribution caused by insulation between adjacent components, difficulty controllably shaping complex shapes without damaging them, lack of effective cooling processes leading to increased temperatures at certain points within the object's interior, and potential damage to sensitive areas near it if there were no efficient way to prevent these issues beforehand.
