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 KNNJOO SX vertical moulding machine, the new DT offers an affordable continuous wheel blast solution to match.

HAOPIN 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 HAOPIN shot blast wheels as standard. The HAOPIN wheel offers excellent blasting performance and unbeatable service life for the main blast components, which are made from hardened tool steel.

The HAOPIN offers even more wall strength through its wear lining, which creates an airtight and completely insulated housing as well as easing maintenance and repairs. There is a full range of variations and sizes available to ensure the chosen wheel is specific to the job in hand.
