The production process of sliding door locks can vary depending on the specific type and design of the lock. However, a general process might include these steps:
1. Concept and Design: This first stage involves designing the lock keeping in view the practical application, aesthetics, and security requirements. Software like Computer-Aided Design (CAD) is usually used for precision.
2. Mold Casting: A mold or die of the lock is created as per the design. This is typically done through a process called die casting. Here, molten metal, usually zinc, is cast into the shape of the lock.
3. Machining: Once the initial casted product is cooled and hardened, it is sent for machining where the cast is refined. This process can help achieve the necessary dimensions and shape of the lock and includes processes like milling, grinding, drilling, or turning.
4. Polishing: After machining, the product is then polished to a smooth finish. This might be followed by nickel or chrome plating to provide a smooth and shiny finish.
5. Assembly: Different components of the lock, including sliding mechanisms, keys, knobs, etc., are then assembled.
6. Testing and Quality Control: The assembled lock is then tested for functionality and durability. The quality control process ensures that the lock meets required security and safety standards.
7. Packaging: After passing quality control, the locks are then packaged for distribution.
Please note that when it comes to manufacturing locks, some strict guidelines and standards must be followed, which vary by country. Always ensure these standards are met in the production process to ensure the safety and integrity of the product.
