Metalock NS CO., LTD is the sole Metalock International Association member company in Thailand. Our core business is specialty casting repairs utilising the Metalock process and associated machining as required including small manufacturing, jobbing etc.

We have strong ties with Metalock of Australia P/L [established 1952] based in Melbourne with branches in Perth and Sydney: they provide technical training and assistance in developing the Thai group.

Our staff have undertaken extensive repairs on major equipment for power plants, cement mills, sugar mills, pulp and paper manufacturers, refineries, chemical plants, mining, shipping, rail, construction equipment and press / forging companies.


History
Metalock originated in the oil fields of Texas in the mid 1930's to overcome the explosive potential of welding repairs. Therefore a system was developed which eliminated heat, and had many ancillary advantages, including the elimination of distortion, which in turn obviated the necessity of re-machining in the great majority of cases. Subsequent development by the U.S.A. defence forces during World War II were responsible for the spread of this technology and its acceptance in the heavy industries, especially marine. 

Further development in the 1950's lead to the establishment of the Metalock International Association, of which has now grown into a unique organisation operating in over 70 countries throughout the world. Conferences are held once a year in various parts of the world, and these enable members to update techniques and extend the services offered. With this economy of scale, the research and development costs, marketing and promotion are off-set through all of the Metalock member companies. 

The Metalock Process is a repair system based on fundamental engineering principles.

• Repairs to cast iron, steel and other alloys
• Many repairs can be carried out onsite, with usually a very great saving in time and dismantling.
• Maintains alignment with little or no re-machining required.
• Dampens and absorbs compression stresses and spreads the tensile strains.
• Distributes the load away from fatigue points.
• The repair being completely cold does not require the application of heat which often introduces fresh stresses.
• A pressure tight seal can be achieved due to the interlocking between Metalock keys and studding. 
• The Metalock repair process is recognised by the Classification Societies.
