Operating Principles

The Semi down draft type paint spray booth is suitable for any type of Air-less and Electrostatic painting. The system consists of painting booth enclosure, air intake filter, Filter channels for paint trap, air exhaust system, complete with electric motor, outlet duct, canopy etc. The fresh air enters into the system from the top of the booth passing through 2 stage filters. This allows air to flow vertically downward thereby washing the operator and the job for better visibility to the operator. Simultaneously the exhaust air system sucks the suspended paint particles and fumes from the booth. These suspended paint particles gets trapped in the filter channels which are provided on the bottom side of the wall.

Fettling/decoring Machine

Surface Finishing Equipment Co. have introduced Decoring Finishing Machine Rotary Drum Type. This machine houses Rotary Drum Capacity 150 Kg. / 2.5 Cft. and Dust Collector Unit. The components are loaded in specially designed drum and the drum is continuously rotated at certain RPM. Due to rotation of Drum, the tumbling effect takes place, resulting into deburring / decoring / fettling of the component. Timer is provided which automatically stops the machine at preset time. The dust generated during operation is collected in Dust Collector Unit. The Control Panel is provided for controlling Electric Circuit etc.

Suction Blaster is the simplest and most effective way to remove corrosion and old paint. Suction Blaster is a clean, dust free sand blaster that leaves the surface cleaned and well prepared for painting, filling etc. When the cabinet and power module are correctly set-up, the cabinet is ready for operation by actuation of the foot pedal. Fully depressing the foot pedal causes air to flow through the blast gun. Air moving through the gun draws media into the blast gun mixing chamber. The media mixes with the air and is propelled out the nozzle. After striking the object being blasted, the blast media, along with fines, dust, and byproducts generated by blasting, fall through the grate into the cabinet hopper. These particles are drawn into the reclaimer for separation. Dust and fines are first separated from the reusable blast media. Next the media is screened of oversize particles, and returned to the reclaimer hopper for reuse. Dust and fines are drawn from the reclaimer into the dust collector which traps the dust, discharging clean air. When the foot pedal is released the blasting stops.

indexing table type with classifier

this is continuously operating hanger / table type peening machine having two/four indexing table / hanger. One is for blasting and second is for loading & unloading operation.

the machine fulfills all essential requirements for shot peening operations as per international standards like shot classifier, shot measurement device cum controller & shot speed and direction controller.

surfex robotic shot peening machines with following features:
the shot peening process is based on the effect of introducing compressive stresses in the surface of a metal part by controlled impinging with spherical particles. By this the resistance against fatigue will be increased and therefore also the life of a part.in the space and aircraft-industries the advantages of the shot peening process are already known: the increase of the fatigue-life of critical parts without weight increase. The designers who used shot peening in applications where the effects of fatigue were caused by grinding, electrical discharge- and electrochemical-machining (edm and ecm), electroplating, anodising, thermal spraying and welding. It also can help increase resistance to fretting, galling, caviation erosion, stress-corrosion cracking, intergranulair corrosion and hydrogen-embrittlement.

we are specializes in the general blast technologies for cleaning, roughening and activating surfaces. This way we were able to encounter demands of the industry in the for the shot peening process.

to control the shoot peening process, one needs the very precision of the shot peening parameters. Surfex started with the development of precise controlled parameters:

shotsizeshot material and shot shapeshot velocity and shot flowrateaiming of the nozzles (distance and angle)shot peening time

these parameters determine the intensity (indication for compressive stress) and the coverage (indication for effectively impinging the complete surface).

surfex shows its capability to precisely control, monitor and record the critical shot peening parameters.
