Bolt Mold Loading & Unloading
With PM Manipulators, Mold Handling, Positioning, and Assembly in Bolt Production Lines Are Now Safer and More Efficient
Challenges in Mold Handling for Bolt Production
In bolt production lines, dies, die housings, and fixture sets are often too heavy and surface-sensitive to be handled manually.
During the placement or removal of these components, operators face high physical effort, unbalanced lifting, and potential workplace injury risks.
PM Industrial Manipulators eliminate these challenges through pneumatic handling systems specially developed for lifting, positioning, and assembling heavy molds used in bolt manufacturing machines.
Precise Assembly and Positioning with Pneumatic Manipulators
Operating on a fully pneumatic system, PM manipulators enable the rotation, alignment, and precise placement of molds at 0°–90°–180° by a single operator — safely and effortlessly.
Thanks to this technology, molds can be positioned into the machine perfectly aligned and without surface damage.
