Environment: Marine (salt atmosphere)
Lead time: 10 business days

Challenge

A shipowner needed replacement locks for glass doors on the passenger deck of a marine vessel. The original locks had corroded after years of service in a marine environment. Full dimensional compatibility with existing holes in tempered glass was required, and the material had to provide corrosion resistance in a salt atmosphere.

TMT Solution

We designed the locks from scratch based on measurements from the originals. Bodies were milled from AISI 316 stainless steel blocks on a 3-axis CNC machining center. Locking pins were turned with h7 tolerance and working surfaces ground to Ra 0.4 μm. Springs and fasteners were sourced in acid-resistant versions.

Result

We delivered a complete set of 8 locks in 10 business days. After installation, the shipowner confirmed full compatibility with tempered glass and locking mechanisms. The locks passed a 500-cycle open/close test without issues.

Frequently Asked Questions

Do you manufacture stainless steel components for marine applications?

Yes, we produce components from AISI 304, 316, and 316L stainless steel for marine and offshore applications. We select the material grade based on corrosion exposure level — for salt environments we recommend minimum AISI 316.

Can you reproduce a part from measurements of the original?

Yes, we do reverse engineering — based on measurements from the disassembled part, we create technical documentation and manufacture the replacement. Measurements are taken with digital calipers and micrometers to 0.01 mm accuracy.

What is the typical lead time for stainless steel components?

Typical lead time is 7-12 business days depending on complexity. Components requiring additional finishing (grinding, polishing) may add 2-3 days.
