Metalock Process

What is Metalock?

First formed in 1953 by 14 companies who recognised the unique engineering potential of the Metalock process, the Association now has over 70 Member companies worldwide.

Through the common bond of the Association, individual Metalock member companies are able to exchange staff, technology and ideas relating to engineering repairs. Our members are trained in accordance with the Association’s guidelines and have in-depth experience in the use of the unique Metalock cold repair process.

Exchanging knowledge, research and operational cooperation between members is the main purpose of the association; every year members gather together somewhere in the world solely for this reason. During the rest of the year, staff constantly collaborate across the globe, especially when a member is tackling a complex engineering project.

The Metalock metal stitching process

This engineering process is sometimes known as metal stitching or metal locking, and has developed since its inception in the late 1930’s. The process has been repeatedly proven, and subsequently gained a worldwide reputation for reliability and speed of repair. Over time the Association has developed the process, to maximise its effectiveness and ensure its dependability.

Why use Metalock?

A casting repair procedure for the greatest return of strength
A repair procedure for pressure repairs
A repair procedure for repairs in a corrosive environment
Only Members of the Association use Metalock alloys MN211 & MN555
Only Members of the Association are issued with a yearly signed Charter

Masterlock is the name for inlays of high strength alloy inserts. These inserts are inlaid at points of high strength concentration, or in sections subject to overloading and subsequent fracture.

Masterlocks can be of various shapes and dimensions and the size and shape vary with the requirements of each repair

Engineering excellence

The Metalock International Association has developed and tested a new stainless key (MN555) to facilitate component repair at high temperatures of up to 550 degrees Celsius.
