Stem for Better Extrusion

The stem acts as a column, transmitting the force of the main cylinder to the billet. It must operate under sometimes extremely high loads without bending, cracking, or upsetting.

Castool stems are custom designed and modeled specifically for the pressure of the press on which they will be used.

Castool is a global leader in Stem

The advantage of considering the process of extrusion as a total system has already been well established and it is practiced by most world-class extruders. The ultimate extrusion system would therefore have all major components designed and produced to work together and be provided by a single supplier.

Castool is the only global supplier to the extrusion industry that can provide both a complete line of products, and trained experienced technicians to help the extruder to get maximum productivity from his system. This service is available wherever Castool products are sold.

Single sourcing and undivided responsibility distance a complete Castool tooling package from all others. A typical Castool single press tooling package includes all necessary spares.

 

Stem Product Specifications

The stem is an extension of the ram, forcing the softened billet through the die. It must operate under sometimes extremely high loads without bending, cracking, or upsetting. It is essential that the load be uniformly applied. Uneven loading will eventually cause bending or breaking. Care must be taken to avoid this situation, as a stem break can be catastrophic, resulting in damage to the press, lost production time and possible injury.
