Does the hot melt glue pot consume electricity when it’s always on? Three energy-saving misconceptions explained at once

Many masters feel that “keeping the glue pot on is the most electricity consuming”, so they frequently switch it on and off. actuallyRepeated cold start consumes more power and damages equipment than insulationBelow are three common misconceptions.

Misconception 1: Keeping it on=burning at full power all the time

The glue pot isThermostat ControlAfter reaching the set temperature, only continue heating when the temperature drops, and the insulation power is usually only 10-30% of the rated heating power. Taking a 5L glue pot as an example, the insulation is about 0.3-0.6kW · h/hour, not the entire 2-3kW burning process.

Misconception 2: Turning off after work is the most economical

The next day, Cold Start needs to melt the entire pot of glue from room temperature to 160 ℃ again,The power consumption of a single cold start is often equivalent to several hours of insulationAnd the thermal shock accelerates the aging of the seal and heating tube. It is recommended to keep the insulation overnight (or set a low-temperature standby) for continuous production.

Misconception 3: The higher the temperature, the faster and more cost-effective the melting process

Overheating will only increase carbonization, smoking, and power consumption,Not significantly speeding upSet the most economical temperature according to the recommended temperature for adhesive particles (150-170 ℃ for books and magazines, 140-160 ℃ for sealed boxes).

Three tips that can truly save money

Choosing glue also affects power consumption

Rubber particles with good fluidity and moderate melting point (such as Sunlife hot melt adhesive universal type for books and magazines) heat up quickly, are not easy to carbonize, and are more cost-effective in the long run than “high melting point hard firing”. Guangzhou Sunlife Trading can provide insulation recommendations based on the capacity of your glue pot.

Frequently Asked Questions

Q1: Should we close if we don’t produce on weekends?
It is recommended to close, but reserve time for adhesive glue during the cold start on Monday and do not force acceleration.

Q2: How many insulation gears are suitable?
A temperature 20-30 ℃ lower than the working temperature is sufficient, which not only prevents adhesive bonding but also saves electricity.
