Contribution of Direct Drive Technology

Flexibility yields productivity

The Delta-Phase® Vibratingout can be used for sand to metal ratios as low as 5:1 and as high as 60:1. The provided controls accommodate an unlimited number of recipes for diverse casting production. In addition to main line sand/casting separation, the shakeout may also be used for lump breakers, sprue cleaning, and casting de-accumulation.

The Delta-Phase® Vibratingout was designed with maintenance and process flexibility in mind. The last thing metalcasters want is more high maintenance equipment. By reducing maintenance and increasing operational flexibility, the Delta-Phase® Vibratingout will pay immediate dividends to any foundry operation.

Direct drive reliability

The key feature of the Delta-Phase® Vibratingout is direct drive technology. Direct drive is a simple, robust design that utilizes long-life, spherical roller bearings and eccentric weights to drive the system. The eccentric weights are inertially synchronized, which eliminates the need for any gearboxes or timing belts.

Compare this design to a two-mass natural frequency shakeout–with its multiple vibrating masses and a forest of coil springs—and the advantages are obvious. Although the natural frequency design is precisely tuned to reduce the horsepower requirements of the shakeout, it is also very sensitive to any upset conditions or lax preventative maintenance. Most owners of natural frequency shakeouts are painfully aware of the problems that usually occur after a period of tough operation: sticking sand, jammed castings, and loose springs. The typical result is hours of downtime to repair cracks or replace springs.

The direct drive design is not a tuned natural frequency system, therefore it is not sensitive to mass and speed changes or loose springs–all of which cause an overstroke condition. Overstroke is the leading cause of structural damage in all vibratory equipment! The Delta-Phase Vibratingout will not overstroke due to its direct drive design.
