In South Korea’s fast-growing electronics industry, camera modules have become a critical part of smartphones, vehicles, and security systems. As lens assemblies get smaller and more complex, UV glue bonding has become the preferred method to achieve strong adhesion and airtight sealing. However, many production lines still face a common problem: overflow and uneven glue distribution during lens bonding.

When UV glue overflows, it can contaminate the lens surface, block optical paths, or create bubbles inside the bonding area. These defects not only lower production yield but also increase cleaning and rework costs. For camera modules used in vehicles, where reliability is non-negotiable, even a small bonding failure could lead to warranty issues or product recalls.

To solve this, many Korean manufacturers are turning to servo-driven screw valve technology. Systems such as the KSP0450 precision dispensing valve use a rotor-stator mechanism to deliver UV glue with a stable, non-pulsating flow. Unlike pneumatic or manual dispensing methods, this ensures bubble-free, repeatable dosing even when working with high-viscosity adhesives. By controlling the exact glue volume, the system prevents overflow and ensures each cavity or bonding point receives consistent coverage.

For example, in mobile phone CCM (Compact Camera Module) assembly, the KSP0450 allows UV glue to flow precisely into tight gaps without spilling over the edges. In vehicle camera production, where sealing performance is critical, the same technology ensures complete filling of the bonding area, improving insulation and protecting against moisture over time. Korean production engineers who have adopted this approach report higher yields and reduced material waste, as every drop of adhesive is accurately placed.

Another advantage is flexibility. The system works not only with UV glue but also with epoxy adhesives, giving manufacturers more options depending on whether they need light curing or heat curing in different bonding processes. Combined with easy integration into automated lines, it supports the shift toward smart manufacturing in Korea’s electronics sector.

As South Korea continues to expand its role in global semiconductor, display, and automotive electronics supply chains, demand for precise, reliable dispensing solutions will only grow. Avoiding overflow in UV glue bonding is not just a matter of quality—it directly affects production costs, long-term reliability, and customer satisfaction.

For Korean manufacturers looking to improve their camera lens bonding processes, investing in advanced dispensing technology like screw valves may be the most practical way forward. With better control, fewer defects, and higher throughput, production lines can stay competitive in a market where precision is everything.
