A novelty at the AMB trade show: For the first time Walther Trowal displays shot blast machinery at the show

At the AMB trade show Walther Trowal displays not only mass finishing but also shot blasting equipment for blast cleaning of castings and stampings. The new troughed belt shot blast machine is characterized by its small footprint, and the TT high-energy mass finishing system requires 20% less energy.

The new tumble belt shot blast machine can be seamlessly integrated into manufacturing operations 
At the AMB trade show Walther Trowal introduces the compact continuous flow troughed belt shot blast machine, model THM 300/1. This machine was specifically developed for treating high volumes of small, delicate work pieces with thin walls. It can handle aluminum and zinc die-castings with diagonal measurements between 20 and 150 mm. For example, this includes toy cars, components for consumer electronics or fittings for the furniture industry.

For the first time a continuous flow shot blast machine is now available for treating small work pieces. With a footprint of only 1.4 x 2.7 meters it can be easily integrated into existing manufacturing lines. 

With the unique troughed belt transport system the work pieces are gently passing through the machine in a spiral movement. Since the work pieces are continuously tumbling over each other, they are evenly blasted on all sides.

Meik Seidler, sales manager shot blasting at Walther Trowal recognizes a distinct shot blasting trend: „The THM continuous flow blast machines with their unique troughed belt transport system can be easily integrated into interlinked manufacturing processes. They are increasingly replacing conventional batch blast systems. The raw work pieces are entering the machine at the same cycle at which they are produced. This eliminates the transport from one manufacturing stage to the next, and intermediate storage is no longer necessary.”

Potential customers who see the displayed machines at the exhibition, can conduct processing trials with their work pieces at the new test and training centers in Haan, Germany, and in Grand Rapids/Michigan, USA.

New Turbotron centrifugal disk finishing machine requires up to 20% less energy 
With new energy-efficient electric motors Walther Trowal succeeded in lowering the energy consumption of its Turbotron centrifugal disk finishing machines TT 90…A/2C by up to 20%. These high-intensity systems allow the fast deburring, edge radiusing, surface smoothing and, even, polishing of small to mid-size work pieces. 

With the new option “gap rinsing and automatic gap setting” these machines are ideal for finishing extremely thin precision stampings. The pressure created by the gap rinse feature prevents thin-walled work pieces from migrating into the interface (gap) between the rotating spinner and the stationary work bowl. 

Christoph Cruse, general sales manager at Walther Trowal, identifies more benefits for his customers: „Contrary to traditional centrifugal disk finishing machines the TT systems are working with a high-water level in the work bowl, whenever thin work pieces must be deburred and smoothed. This prevents them from sticking to each other or adhering to the work bowl wall.” 

Walther Trowal offers the new Turbotron systems with the “gap rinsing” option as stand-alone machines with manual work piece loading and unloading as well as larger, fully automatic systems with integrated loading device, vibratory screening device and media return unit.
