EIGHT TANK PRE-TREATMENT & POWDER COATING
SHELL ASSEMBLY
ELECTRICAL ASSEMBLY & BUSBAR WORK
      • Fully modular design of LV switchboards

      • CRCA sheet punching on most modern CNC operated amada turret punch presses

      • Switch board members after punching bent on state of art CNC operated amada bending machines

      • Shell structural members sheared on shearing machine & punched on power press

      • All the components thoroughly inspected before sending for pre-treatment / powder coating
      • Material incoming receipt

      • Loading to pre-treatment basket

      • Pre-treatment carried in eight tanks using auto loader :

        • Degreasing in tank 1

        • Water rinse - 1 in tank 2

        • Derusting in tank 3

        • Water rinse - 2 in tank 4

        • Activation in tank 5

        • Phosphating in tank 6

        • Water rinse - 3 in tank 7

        • Passivation in tank 8

      • Water dried in a separate tank after pre-treatment

      • Pre treated items unloaded and inspected

      • Items loaded to an overhead powder coating conveyor, having a capacity of handling 15 tonnes of components per day

      • Powder spraying carried out in most modern automatic booth with robotic spray guns & powder recovery system of WAGNER, Germany, with a capacity of 15 tonnes of components per day

      • Powder is baked in a baking oven at 200 degrees centigrade, as the items move on the powder coating conveyor

      • The components are then inspected and despatched to shell assembly

      • Dedicated & well planned floor area of 33000 sq. ft for shell assembly

      • Three separate bays for assembly with clear identified walkways / passages for safe men & material movement

      • Equipped with pneumatic lines & pneumatic tools, covering the entire shell assembly area, with independent air compressors

      • Two 3 tonnes goods lifts at each end of assembly area for convenience of incoming shell components & outgoing assembled shells to electrical assembly

      • Electric stackers / hydraulic pallet trucks for ease in material handling

      • Formed in place Foam Gasketing :

        • Using the best in place sonderhoff high-performance low pressure fully- automatic three component mixing and dosing system for gasket gluing

        • Precisely processing liquid, medium to high viscose media such as polyurethane, silicones, epoxy resins and other polymer reaction substances, as per customer needs.

        • Unique facility to glue inspection glasses/ windows using bicomponent glues

        • Achieving a high degree of ingress protection

      • Dedicated & well planned floor area of 37800 sq. ft. for electrical assembly/ stores/ busbar section

      • Three separate bays for assembly with clear identified walkways/ passages for safe men & material movement

      • Equipped with light & heavy duty crimping tools, wire skinners, drills, screw drivers, polishers, blowers, vacuum cleaners, etc. For production of international quality panels

      • Electric stackers/ ACD handling trolleys/ 2.5 T hydraulic pallet trucks for ease in material handling

      • Busbar work carried out on Arco whitney make bus bar working machinery & power presses in a separately designated area

      • Bus bar work certified to comply with IEC 61439-1&2 standard for temperature rise tests & short time withstand ratings

      • Heat shrinking of sleeves over busbars in sleeving machines with temperature & speed controls

      • Busbar insulators certified to withstand glow wire test
