Manufacturing Process Control

Manufacturing Process is Control by ISO norms.Plant-wide use of ISO 9001:2008 approachAll radiators should manufacture under IEEMAstandard.

Type tests can be carried out at customer defined

frequencies

Routine Tests carried out for each product

100% leak test at standard specified operating pressure

Control on ancillary process such as Forming, Spot & Seam

Welding, MIG Welding, Assembly , Painting and Packing.


7/29

Forming Forming is done on advanced CNC roll forming machine according

to the lengths as per customer requirements. At this stage requiredquantity of cooling channels are created which provide the

transformer oil circulation inside the radiators.


8/29

Spot & Seam Welding : Radiator slices are welded together by using multiple spot welding

at the determined points where the oil grooves are contracted toeach other. Edges are welded to each other by using seam welding

machine and prepared complete panels for Assembly.

Testing facilities

All product are validated at Transpares , state-of-the-art, in-housetesting facilities

100 % Leak profness test : As per standard practice radiator tested

underwater at 2 kg/cm sq. air pressure for the period of 30 minutes.


14/29

Oil flushing & Internal Coating : Radiator internal surface is protected by

flushing of Transformer oil and varnishing.


15/29

Painting: Flood painting a unique painting process has beenadopted to achieve free flow (sag less) finished surface

with uniform paint DFT throughout the surface of

radiators. Total Dry Film Thickness provided is inbetween 80 to 250 as per customers specification.Separate paint booths are being used for Primer,n erme a e na coa .


16/29

Packing: Packing being the most effective area of concern,

Transpares makes radiators are packed with sturdywooden blocks, properly nailed & tightened with steel

straps. Domestic radiators are packed either in woodenpallets or in crates as per customers requirement

Proper care is taken with all safety measures for Export

bubble sheet covering


17/29

Inspection & Quality Control : Radiators are inspected and controlled stage wise toachieve good quality of the product. Continualimprovement action is taken against customer

comments.
