The Obstacles to Pressing Thin Parts

 

Thin parts have historically been a challenge in powder pressing.  Slight variations in powder bulk density, fill characteristics, or die fill position can have a profound impact on these thin parts.  Additionally, material flow characteristics and small fill height to compact height aspect ratios greatly impact finished part height consistency.

Safety First

 

Applications for this type of machine sometimes require the use of materials that are combustible in certain environments.  Gasbarre has this covered. We have worked with our customers to develop safety mechanisms between the hopper and shoe to reduce the potential for damage to the machine and facility while creating a safe work environment.  We also offer the option to locate your hydraulic power unit in remotely to optimize space and eliminate contamination.

The Answer to Thin Part Challenges

Gasbarre 250HEP

Gasbarre 20SEP

Gasbarre offers versions driven by direct drive servo motors to roller screws, hydraulic systems and hybrid variations of the two.   All of our products have closed loop controls for the top, bottom and filling axis.  Part setup via Gasbarre specially developed HMI includes the ability to store all part recipes for easy setup time after time.  Many of these applications require the ability to press to pressure – Gasbarre includes that ability as a standard feature.
