Our THM continuous processing machines are used for blasting workpieces made of aluminium, zinc, brass and steel, primarily for
- descaling
- Deburring
- roughening
- Cleaning
- shot blasting
Thanks to their unique trough belt principle, they can be integrated very easily into networked processes.
Blasting technology creates uniform surfaces
Consistent blasting with continuous shot blasting systems
Trough-belt continuous processing machines offer significant advantages, particularly for workpieces where high standards of surface quality are required: within the trough, the individual parts hardly come into contact with one another; instead, they roll gently along the soft PURALON® coating on the trough bars and do not collide with one another.
Our THM continuous blasting systems are designed for both bulk material and complex, delicate individual parts made from various metals.
Examples of steel components include pliers, ring spanners and open-ended spanners, or car connecting rods. Brass fittings are also processed in these systems. Typical aluminium forgings include steering knuckles and swivel bearings, as well as die-cast aluminium parts such as housings, lids, caps and levers.
Examples of zinc die-castings include model car casings or delicate parts used in the furniture, electrical and Automotive industries.
Many structural components made of magnesium – such as dashboard supports in vehicles, and housings for chainsaws and engines – are also processed in our THM continuous processing machines.
Our THM continuous shot blasting systems are also used for surface hardening through shot peening.
For continuous blasting , we use blasting media of varying hardness, shape and size. These are often made of steel or stainless steel.
In particular, the blasting of forged or die-cast parts made from light metals requires a soft or non-ferritic blasting medium. Aluminium is being used more and more frequently for this purpose: it enables an even gentler surface treatment whilst reducing operating costs.
Blasting technology for modern production lines
Continuous shot blasting systems
integrate seamlessly
Continuous processing machines replace time-consuming batch processes, as they are fully integrated into the production lines. Many users position the blasting machine immediately downstream of their forging line or die-casting machine. This ensures that the parts enter the machine at the same rate at which they are produced in the upstream equipment. Both the intermediate transport from one process stage to the next and the temporary storage of parts are eliminated entirely.
