    Today, let's have a look at how a qualified lock is produced. The production of a mortise lock will go through a whole process of parts processing, components 

processing, finished product assembly and packaging. We will talk about some of the key processes.

1.Forend machining process

Laser cutting → Welding → Surface finish

Forend is one of the mortise lock parts. We made it by laser cutting machine. We can provide 

20/22/24mm width forend, also round corner and square corner for your choice. And the 

machining process also includes welding and surface finish.

2. Lock case machining process

Stamping → Automatic riveting

Our mortise lock case is 1.5mm thickness. The material is Galvanize stainless steel SECC.

3. Latch bolt machining process

Drilling holes → Automatic assembly

We have the fully automatic assembly machine for our latch bolt. Our mortise lock latch passed 

200,000 test cycles according to EN12209 standard.

4. Deadbolt machining process

Riveting → Surface finish

The deadbolt of our mortise lock passed 50000 test cycles according to EN12209 standard.

5. Automatic Assembly and packaging

After all the parts and components are finished, we can enter the assembly process. We used to do 

the full mortise lock assembling job by workers. With the introduction of automatic assembly machines 

last year, the production efficiency and quality have been greatly improved. Finally, the finished mortise 

lock will be put into plastic bag for packaging.

6. Inspection

We do the first & last and patrol inspection in parts’ process. And do the full inspection when the 

product is produced. We also do the randomly inspection after packaging. These inspections make 

sure the stablity of our products quality.

In a word, Jianhua is in dedicate to produce qualified mortise locks. Our locks comply with European Standard EN12209, and got CE and UKCA certification. 

And the fire resistance test can match 90mins on timber door, 240mins on steel door. We also do annual audit according to CE requirements. If you need the
