A Solution For The Troublesome Rusting

India has been one of the leading manufacturing hubs for heavy and light machinery. It supplies various machined components across the world like Cylinder Block, Cylinder Head, Crankshaft, Camshaft, Connecting rod, Pistons, Fuel injectors, Gears, Bearings, other automobile, and heavy engineering parts, etc. These parts are made up mostly of ferrous materials and face the most common issue of Corrosion as the parts are case sensitive.  

As it affects

From production to assembling, these parts are in WIP, then storage at manufacturer location, surface and sea shipment, storage at receiving location for a period of around 6 months to 2 years, on average, and sometimes even more. Corrosion has always been a challenge in long term storage because it is quite challenging to protect the parts for such a long time from rust. Due to corrosion, the part may get rejected by the user and that will be a huge loss for the manufacturer. Also, the corroded part would be of no use, if used in a vehicle, would damage the performance, thus cannot be reused. Hence there is needed something for Prevention and Control of Corrosion. 

As we prevent it… 

One of the popular bearing manufacturing companies in the world is having a manufacturing facility near Chennai, India; which supplies various types and sizes of bearings to various locations in the world. Bigger size bearings or bearings used as a spare part, are produced at this manufacturing location and shipped to customer location and assembled at usage location as and when required, these types of bearings require longer storage time. The more time they spend, the more are the chances of corrosion, and the more is the need for efficient prevention of rusting.  For long term corrosion prevention, the process has to be done with care. 

This location is involved in manufacturing Cylinder and Taper Roller bearing and it exports them to countries like USA, Europe, China, Japan and Singapore. Since they wanted to store the bearings for a longer period of about 10+ years, they contacted Zavenir seeking a solution. Zavenir carefully observed their manufacturing process, shipping condition, storage environment at receiving location and offered them complete package by suggesting the following process as solution: 

Nox Rust® Dewatering Fluid for better surface preparation before applying rust preventive oil, 

High quality Nox Rust® Rust Preventive Oil for long term protection,

Individual Daubert® PMG® VCI Film to provide additional support for corrosion protection and 

Superior Daubert® Aluminium Foil Bag with Vacuum Packaging for near to zero MVTR (moisture vapour transmission rate) and prolonged rust protection. The lower MVTR ensures no further moisture/oxygen can enter in the packaging. The special type of Aluminium Foil Bag ensures the vacuum holding for 10+ years to provide oxygen less environment for bearing to make the bearing rust free during the packed period. The cost of Daubert® superior Aluminium foil was a little high but when it was compared with bearing rejection cost it was negligible. The overall cast was reduced.

This Daubert® Aluminium Foil Bag is a benefactor as far as the Prevention of Corrosion of Metals is looked at. It has proved to be an efficient solution to the problem of rusting.

The whole problem can easily be solved with the help of some easily applicable accessories. Zavenir has been providing premium quality products to assist your automobile management processes.
