Why do IG units have sealant leakage?

Sealant leakage is usually caused by incorrect sealant temperature or viscosity, poor spacer bending accuracy, glass size deviation, surface contamination, or unstable 2K sealing ratios.

How can I prevent sealant leakage in insulated glass units?

Maintain correct sealant temperature, ensure precise spacer bending, keep glass surfaces clean, use stable A/B sealant ratios, and consider using an automatic sealing robot for consistent quality.

Can equipment problems cause IG sealant leakage?

Yes. Butyl extruder temperature errors, 2K sealant mixing issues, worn nozzles, and inconsistent machine pressure can all lead to poor sealing performance and leakage.

Does manual sealing increase the risk of leakage?

Manual sealing often leads to uneven sealant lines and inconsistent corner filling. Using an automatic IG sealing robot significantly reduces leakage and improves product stability.

What is the best long-term solution for reducing IG sealant defects?

Investing in automated equipment—such as an IG sealing robot, automatic spacer bending machine, and calibrated 2K sealant pump—offers the most consistent and long-term solution to eliminate sealing problems.

Glass protetive film Applicntor: special equipment for glass protective film lamination

How to Protect Insulating Glass During Production, Storage, and TransportationInsulating glass is widely used in construction, automotive, and other industries. To keep it intact and prevent scratches, dust, and stains, an insulating glass laminating machine is highly effective. The protective film applied by the machine is smooth, wear-resistant, and fits tightly to the glass surface, preventing scratches from hard objects and keeping the glass clean.During transportation, the protective film also absorbs impacts and reduces the risk of breakage. For environmental factors like humidity and UV rays, special protective films can provide moisture-proof and anti-UV protection.In summary, the insulating glass laminating machine ensures the glass remains in excellent condition throughout production, storage, and transportation, offering reliable protection and maintaining quality.

What is a Glass Protective Film Applicator?

A Glass Protective Film Applicator is a machine designed to apply protective film on glass surfaces. It prevents scratches, dust, stains, and other damage during production, storage, and transportation.

Can it be used for all types of glass?

Yes. It works with various glass types, including insulating glass, tempered glass, and architectural or automotive glass.

How does it protect glass?

The applicator evenly applies a smooth, wear-resistant protective film that tightly adheres to the glass surface, blocking scratches, dust, and stains, keeping the glass

Does it help during transportation?

Absolutely. The protective film absorbs minor shocks and reduces the risk of breakage or surface damage during handling and transport.

Can it protect against environmental damage?

Many protective films applied by the machine offer moisture-proof and anti-UV properties, helping prevent damage from humidity, sunlight, and other environmental factors.

Is the protective film reusable?

No. The film is designed for single-use protection to ensure optimal scratch, dust, and environmental resistance.

How does using this machine improve efficiency?

By reducing glass defects, minimizing cleaning time, and lowering breakage risks, the Glass Protective Film Applicator increases production efficiency and ensures high-quality glass output.
