Since last over 25 years we get repeated & regular calls from our old & new would be clients for the finishing of metal parts. It may be castings, forgings, aluminium die castings, zinc die castings, brass components, gun metal parts, tempered components or the sheet metal parts.

I remember a customer who visited me from Agra, almost 10 years ago, for the Finishing of brass hinges. He brought few samples with him. Moreover he could not tell me about the type of finish he required. He just asked for a better finish.

Though i could easily offer different type of finishes by using either a vibratory finishing machine OR a suction blasting machine i.e. sand blasting machine with a suction blasting gun as well a wet blaster. But i knew he had the bulk of material & a single machine won’t be enough for him to meet the targets.

So i took him to my works for a trial on our Airless Shot Blasting machine i.e. Tumblast model. We did a bit of adjustments in the machine and changed the abrasive media to a desired size & quality & asked the client to come inside the workshop.

His samples were loaded in the machine & we did the shot blasting for few minutes. The minute we opened the door of the machine, our client looked more than happy. Amazing results were clearly visible on the Brass Hinge as well on the face of the client. He immediately placed the order with us & took the delivery as desired.

Tumblast shot blasting machines are the best suitable for cleaning & finishing of small to medium size of Castings, Forgings, Aluminium die castings, Brass & gun metal parts, Sheet metal as well hardened components. Options of using a Hanger type machine, a monorail, a table model or a continuous conveyor model shot blasting machines are also available depending upon suitability.

In Tumblast, a conveyor belt rotates inwards, inside the chamber of the shot blasting machine & the components are loaded on it as per the size & capacity of the machine. The door is than closed. Rotor is switched on for throwing Shots or Grits on the components. By this process, the loaded components get a universal finish. Abrasive medias such as Shots or Grits are continuously fed by the elevator of abrasive media. All the dust extracted in the process goes to the attached dust collector. On completion of desired time period, the door is opened & than the conveyor belt is driven outwards. As a result the components can be removed from the chamber. An automatic loading system can also be attached to the shot / grit blasting machine.

The Tumblast shot / grit blasting machines are available in many sizes, right from a 2 cu ft capacity machine to a 15 & 20 cu ft capacity machines. Some of the sizes are: 20″ x 27″, 20″ x 42″, 27″ x 36″, 30″ x 43″, 36″ x 42″, 42″ x 42″ as well 48″ x 48″.

Similarly, Hanger model Shot blasting machines are available in Single / Double door type, Centralised hanger type as well a monorail type. In this model, the components are hanged instead of loading on the conveyor belt. Rest of the process is same. The hanger rotates for a universal finish using multiple rotors depending upon requirement. The benefit is that the components do not touch each other in the process of finishing and hence are scratch free.

Swing table model shot blasting machines are suitable for bigger or heavier components or if the smaller parts are to be shot blasted only one side. Many sizes are available from a minimum 36″ of table to 120″ of table in sngle as well double doors.

Continuous conveyor model shot blasting machines are suitable for smaller components which are to be shot blasted only one side with a single rotor. Multiple sides can be finished by using multiple rotors. Components are fed from one side & removed from the other side duly finished.

The spare parts mostly wearable are made from ni hard or alloy steel to get the maximum life.The main spare parts include the Rotor, Blades, Spring locks, Cage & Impeller, Cage adapter, centre plate, Top segment, Side liners, Round plates as well the conveyor belt. Few precautions are necessary while running the machine.

The Tumblast model of Shot blasting machine if to be used for finishing of smaller components is best suitable and very cost effective. we can be contacted with details of your components for a suitable size & model of shot blasting machine.
