why lock for bags are difficult to make?

Manufacturing locks from zinc alloy can be challenging due to several factors:

Strength and Durability: Locks, especially those used for security purposes, require high strength and durability. While zinc alloy is strong, ensuring the lock can withstand external force and wear over time is critical. Achieving the right balance between strength and malleability can be challenging.

Precision in Mechanism: Locks demand precise mechanisms to ensure they function smoothly and securely. Even a minor flaw in the design or production process can cause the lock to jam or malfunction, making precision engineering a crucial aspect.

Complex Design: Many locks have intricate designs, involving small and detailed components. Manufacturing these components with precision, especially in zinc alloy which can be less forgiving than other materials, requires advanced molding and casting techniques.

Security Concerns: Locks need to offer a high level of security, and any weakness in the material or structure can compromise that security. Ensuring that the zinc alloy used is of the highest quality and is resistant to tampering is a significant challenge.

Corrosion Resistance: Locks are often exposed to various environmental conditions, including moisture, which can lead to corrosion. Ensuring that the zinc alloy is properly coated or treated to resist corrosion while maintaining its functionality is a delicate balance.

Consistency in Quality: Maintaining consistent quality across a large volume of locks is challenging. Even minor variations in the composition or manufacturing process can lead to differences in strength and durability, which is unacceptable in security products.

Testing and Certification: Locks are usually subject to rigorous testing and certification standards, ensuring they meet safety and security requirements. Meeting these standards while working with zinc alloy demands careful attention to detail and quality control.
