Common Dispensing Mistakes

One of the common problems is air bubbles within the adhesive, which can compromise the strength of the adhesive. There are a number of things that can cause bubbling, many of which are related to the pressure during dispensing. Air bubbles can form in fluid lines when an empty adhesive container is removed. In this case, the lines should be flushed after refilling or replacing the container.

Applying more pressure than necessary can also cause bubbling in the adhesive. This can be alleviated by using the appropriate pressure pots for the viscosity of the adhesive. For lower viscosity adhesives, pour-in or drop-in pressure pots are most effective. Ram-style pail pumps are suggested for higher viscosity adhesives.

Green Intelligent Equipment (Shenzhen) Co.,Ltd, a company with lots of experience engineer team in adhesive dispensing industry, could offer professional and technologies and skills to solve all these problem for customers. For example, we equipped servo motor+precise screw rod, and use the customized dispensing valve  for dispensing machine, which could make the machine working smoothly and successfully dispensing the adhesive 1.8mm width and 0.8mm height to meet customers' product need.

Common Curing Mistakes

The most important part of the cure is matching the wavelength to the adhesive. This is also where many people go wrong with curing. The adhesives have a preferred wavelength of light at which they will cure fast and strong. While it is important to achieve this ideal light wavelength, the adhesive will still cure under lighting that is a bit off.

UV-cured materials don’t require UV light. Rather, they need light at a wavelength near the UV spectrum. They can cure in ambient light and any light that matches the frequency required by the chemistry. High-energy light that is closer to the blue-purple end of the spectrum cures faster than ambient or sunlight; it can cure deeper.

The distance of the light source from the adhesive can also affect the cure. If the light source isn’t in a fixed position, each object that is cured with it may receive different amounts of light, causing inconsistent cures. This problem is remedied by having the light built into the automation process, where the products pass by light that is at a fixed distance and intensity. Green Intelligent Equipment (Shenzhen) Co.,Ltd. can further eliminate this step by using an automated system that cures the adhesive immediately after dispensing. We use customized curing light sets(4950W) + customized curing oven for customers’ product.
