Compaction table

The JOEST compaction table has been specially developed for demanding applications in the lost foam process. It enables complete compaction of binder-free molding sand – even in hard-to-reach, horizontal, and multi-angled cavities of complex patterns. Precisely controllable vibration in three spatial directions ensures targeted filling of all mold areas.

The system features resonance-free start and stop behavior and particularly gentle handling of the product – ensuring consistently high mold quality with minimal scrap.

The compaction table operates with multiple electronically controlled unbalance drives that generate a defined oscillation along the X, Y, and Z axes. This allows the molding sand to be precisely directed into every cavity – even in highly contoured or asymmetrical molds. Unlike conventional vibration systems, the operation is free of natural frequency, preventing loosening of already compacted material and enhancing process stability.
The robust design of the compaction table is based on a vibration-optimized steel frame and a modular drive unit. Table sizes are freely configurable – from 1,000 × 1,000 mm up to 5,000 × 5,000 mm – and can be individually adapted to process requirements and plant layouts. Vibration frequency, amplitude, and motion direction are electronically adjustable, allowing the table to be easily tuned to various sand types and mold geometries. The control system can be integrated into existing process control systems.
  • The control system can also be expanded with features such as recipe management.

Fields of Application

The JOEST compaction table is a highly specialized system designed for the efficient compaction of demanding materials and is used especially in sensitive industrial processes. In the Lost Foam casting process, it enables precise sand distribution – even in horizontal cavities – making a critical contribution to the quality of complex castings. The JOEST compaction table also excels in powder metallurgy, where its precisely adjustable vibration profiles ensure uniform compaction and thereby optimal material properties for high-performance applications.
