The working efficiency of the two-component glue potting machine is affected by many factors. The following are key factors and optimization suggestions:
1. Equipment parameter setting
● Air pressure stability:
Insufficient air pressure will lead to slow glue dispensing speed or unstable flow rate (such as the recommended pressure range is not up to standard), and the pressure regulating valve and air compressor performance need to be checked.
Excessive air pressure may cause bubbles or glue waste, and it needs to be adjusted to a reasonable range according to the viscosity of the glue (such as instant glue is recommended to be 60-80psi).
● Proportional pump calibration:
Incorrect AB glue ratio (such as 10:1 is mistakenly set to 5:1) will cause uneven mixing or poor curing, and the proportional pump needs to be calibrated regularly.
Clogged or worn mixers will reduce the mixing efficiency and need to be cleaned or replaced in time.

2. Glue characteristics
● Viscosity and fluidity:
High-viscosity glue (such as silicone, epoxy resin) requires higher pressure and larger-diameter pipelines, otherwise the glue dispensing speed will be slow.
Low-viscosity glue (such as instant glue) is prone to blockage of pipelines due to moisture crystallization, and needs to be sealed and stored and preheated.
● Bubble problem:
If the glue is not fully stirred or there is moisture on the surface of the workpiece, bubbles will occur, affecting the speed and quality of glue filling, and vacuuming or preheating the workpiece is required.
3. Pipeline and glue supply system
● Pipeline design:
Pipes that are too thin (such as less than 1/4”), too many bends or too long will increase resistance and cause delayed glue discharge.
It is recommended to use large-diameter straight pipes and reduce joints, especially for high-viscosity glue.
● Blockage risk:
Instant glue, anaerobic glue, etc. are prone to agglomeration due to moisture or repeated use, and the pipelines need to be cleaned with acetone regularly.
The cleanliness of the mixing tube or static mixer directly affects the smoothness of glue discharge.
