PURPOSE
Transmits the force of the main cylinder to the billet
Must operate under high loads without bending, cracking or upsetting
FUNCTION
It is essential that the stem remains in complete alignment throughout the length of its stroke. It is also essential that the load is uniform. Uneven loading can result from a variety of reasons such as improper installation, distorted pressure plate, misaligned press, jammed butts (causing the container to shift), or improperly cut billets.
BENEFITS
Longevity and safety
Only premium grade forged H-13 (1.2344) and experienced heat treatment is used
Designs are modeled using FEA and machined to reduce stress risers that may causes cracks
Stabilizing stud allows benefits of bayonet coupling with minimal lateral movement
