Leading Technology Today

Automatic manufacturing processes require highly flexible production systems to be able to cope with changing production requirements. Flexible systems can quickly adapt to changes in production rates, lot size, finishing techniques and market demands. The through-feed blast cleaning process offers a number of distinct advantages and ensures efficient and cost effective blast cleaning. Continuous shot blast machines automate production sequences and improve the work environment.

Integrated, Fully Automatic Production from Moulding to Clean Castings

Automatic, Continuous and Dust-free Blast Cleaning

The polygon shaped trough rocks back and forth to gently tumble the workpieces. The frequency of the rocking motion of the trough and the abrasive supply to the blast wheels are controlled based on pre-programmed parameters depending on the flow rate and volume of parts. This ensures optimum blast cleaning results and minimum wear, even when the flow-rate of parts is irregular. The high power abrasive streams - aimed at parts from above - reach, and thoroughly clean all surfaces and interior areas.



Integration Into the Production Line

The unique design makes it easy to integrate DT blast cleaning machines into production lines.

  • Integrated production provides the following advantages:
  • Entirely automatic, continuous production flow
  • Integrated cooling of castings and sand
  • Recovery of moulding and core sand during shot blasting by means of magnetic separator
  • Minimal pollution through complete control and capture of dust throughout the production line right from punchout

Get the Best out of Your Production

A lighter, entry-level version of the established heavy-duty DT rocker barrel tumblast concept is available. The DT-11-350 was designed specifically for the needs of smaller foundries, producing smaller castings in smaller runs. For foundries looking to upgrade to the new DISAMATIC C3 vertical moulding machine, the new DT offers an affordable continuous wheel blast solution to match.

Universal Wheel

The blast wheel is the heart of the blasting machine, as the choice of blast wheel determines the power output and the economics. 

This machine is fitted with U70x500 Universal (indirect drive) shot blast wheels as standard. The Wheels are highly flexible, compact and have rotation in both directions. They provide perfect blast cleaning results and highly convenient servicing features.

The U Blast Wheels are high capacity blast wheels with maximum energy efficiency. Their rugged design means that maintenance is easy, and the special and highly wear resistant cast alloy liners ensure minimum wear and maximum service life of the blast wheel.
