Many customers are concerned. Glue dispensing machine What kind of problems might arise? What should you do if you run into issues with your sealant applicator? Many pieces of machinery don’t always operate smoothly, and just like us humans, they sometimes catch “colds.” So what happens when our equipment “catches a cold”? Let’s take a look now.

In our daily use, glue dispensing machines can experience two types of “colds.” What should we do about it?

First, the glue is uneven.

During the product potting process, Glue dispensing machine During production, if issues such as uneven glue dispensing occur—indicating malfunctions in the gluing equipment—this can severely affect the quality of the product’s gluing process. The reasons for uneven glue dispensing are as follows:

1. The metering pump lacks sufficient accuracy.

This manufacturer certainly conducts inspections before products leave the factory, and of course, newly purchased machines will also be verified upon arrival at the factory. If a machine has been in use for an extended period, it should be calibrated regularly to prevent inaccurate measurements caused by prolonged use of the metering pump.

2. The pipe or mixing tube is blocked.

A pipe blockage occurs when, after just one outdoor use, the pipe may take a long time to become usable again. However, since the outlets of the pipe and valves are not sealed properly, the adhesive comes into contact with air, and over time it will harden and solidify.

A blockage in the mixing tube occurs when the remaining AB components inside the mixing tube are not cleaned up promptly after use, leading to changes in the flow cross-sectional area and uneven glue application.

Second, blistering occurs.

The gel bubble phenomenon is one of the common injection problems encountered during the product gel-injection process. The causes of gel-bubble formation are as follows:

1. When adding adhesive to the machine’s adhesive tank, bubbles may form. After adding the adhesive, simply use a vacuuming method to remove the bubbles from the adhesive.

2. The bubbles produced by the glue are caused by high-speed stirring during the mixing of components A and B. If bubbles do appear, only static mixing can be used—dynamic mixing is not an option.

Buy Glue dispensing machine You need to clearly understand your own purchasing principles. Here are a few points to share:

1. Adhesives: Dual-component adhesive dispensing machines for epoxy AB glue, PU glue, silicone, and other two-part adhesives; single-component adhesive dispensing machines.

2. Gluing Process: For small-batch production, a semi-automatic gluing method is used (e.g., foot-pedal control). For large-batch production and irregular gluing paths, a gluing machine equipped with a three-axis motion platform is employed; the gluing machine automatically follows the pre-set trajectory.

3. Cost: There are various grouting solutions available, and not all grouting applications require the use of machinery. Considering cost, if a particular adhesive necessitates the use of excessively expensive equipment, you might want to consider switching to a different adhesive.

Jiangsu Gaoke Precision Fluid Technology Co., Ltd. primarily engages in the research, development, production, and sales of core components for piezoelectrically driven precision fluid control systems, as well as related complete equipment. By providing customers with high-quality products, the company helps them significantly enhance their production processes and technological levels, improve product quality, boost production efficiency, and reduce manufacturing costs.

The company is a leading enterprise in China specializing in piezoelectric-driven precision fluid control technology and a pioneer in its industrialization. In 2014, the company was the first in the industry to launch a domestically developed piezoelectric jet valve, achieving import substitution for the core components of jet dispensing systems. Through continuous R&D and innovation, the technical specifications of the company’s piezoelectric jet valves have reached an industry-leading level. Its downstream applications now cover multiple sub-sectors of 3C electronics manufacturing, including acoustics, optics, FPC, and complete equipment assembly, and the company is gradually expanding into fields such as new-energy batteries and semiconductor manufacturing.
