The Making of a Lock

Take a glimpse inside the manufacturing process for a magnalock.


When we open a lock hardware box, we usually take for granted all that goes into its manufacture. I recently had an opportunity to visit the Securitron Magnalock Corporation headquarters in Sparks, Nevada. During the tour of the facility, I was able to observe the production of Securitron...

So how does it all go together?

The E-laminates are placed onto a fixture to create the E-laminate stack. The Senstat lock option is also added at this stage.

The wire wrapped coil is then added to the stack and the combination is bound together using an industrial adhesive. The power wires are routed out the appropriate side of the laminates to match up with the circuit board.

The lock circuit board is ready to be attached. Coil power wires and lock power cord are soldered to the board and the board is fastened to the E-laminates. This “sub-assembly” is now ready for insertion into the lock mold.

The sub-assemblies are carefully positioned into a mold and filled with a suitable potting material. The potting material is both an electrical and magnetic insulator. The potting material cures into a hard strong sealant, resistant to chemicals, heat and vandalism.

Once the molded lock has cooled, the entire assembly goes through a machining process to produce a uniform surface. This surface is necessary for good matching contact with the strike plate. The machining process also removes any imperfections from the face of the lock.

After the lock has been machined it goes through a plating process to prevent the exposed portion of the E-laminate stack from oxidizing. During the plating process, the locks are individually tested to ensure the proper plating thickness and conductive properties.

At this point you have a working magnetic lock. The next step is to install the magnetic lock into an architecturally pleasing outside “can” or housing. After the final assembly, each maglock is thoroughly tested again.

The magnetic locks are boxed and await shipping.

Magnetic locks have been around since the early 1970s. They are considered a low maintenance lock.
