Power Consumption Comparison Table for Different Types of Laser Marking Machines

The study compared the power consumption of laser marking machines with different power ratings, ranging from 20 to 200 watts, and analyzed the differences in electricity costs based on actual measurements. The study will help manufacturers choose equipment that is more energy-efficient, according to their processing needs.The booklet contains recommendations for choosing the right power level, formulas for calculating electricity consumption, and energy-saving tips.

Why should we care about how much electricity these machines use?

Many factory owners start out thinking, "How much energy could a laser really consume?" But after a few months of use, they find that their electricity bills are a lot higher than they expected.For example, an 8-hour shift of a 100-watt laser engraving machine uses about as much electricity as an average household consumes in a day.Especially in 24-hour production lines, choosing the wrong power can cost tens of thousands of dollars in electricity each year.Today, we're going to look at how much electricity different kinds of appliances actually consume.

Power consumption of mainstream laser marking machines.

We tested five common models available on the market (20W, 50W, 100W, 150W, and 200W) and recorded data under standard conditions for etching metal signs.

It's a small desktop unit.

Standby power consumption: About 30 W.

- Power consumption: 220W (including cooling system).

- Suitable for: Small batches of handicrafts and engravings.

- Monthly electricity bill: About NT $ 60, assuming four hours of use per day.

100W medium-sized industrial machine.

Standby power: 80 watts.

- Maximum power consumption: 950W.

Application: Car parts.

- Monthly electricity bills: In a three-shift situation, they could reach NT $ 2,000.

200W high-power equipment.

- Standby power consumption: 150W.

- Power consumption: 1800W.

Important Note: A 380-volt industrial power supply is required.

Warning: Electricity drain.

This method of choosing power is the most economical.

I've seen a lot of customers who buy high-power machines for small jobs, like using a truck to deliver a package--a complete waste.Here are three suggestions to get you grounded:

Start-up teams tend to prefer models under NT $ 50,000.

When they first started out, the demand was not steady, and the low-power machine was enough to cover 80 % of the acrylic and wood carving orders.The electricity bill is less than a third of that for a high-power machine, and the payback period is shorter.

For metalworking, 100 watts is the minimum.

Don't be fooled by the "80W is enough to cut stainless steel" line of sales patter. Actual tests have shown that a 100W laser can cut the same area 40 % faster than an 80W laser, and that in the long run it's even more energy efficient.

Hidden energy wasters

The cooling system is the real energy hog. A 500-watt cooling system is standard for a 150-watt machine. When purchasing equipment, it is essential to ask for the total wattage of the whole system.

They teach you how to calculate the electricity cost of every product.

You'd better bring a calculator.

1. Check the "input power" (for example, 1200 W) on the nameplate of the appliance.

2. Record the time it takes to process each item (e.g. 90 seconds).

3. Formula: (power ÷ 1000) × (time ÷ 3600) × unit cost of electricity.

Assuming an electricity rate of NT $ 1 per kilowatt-hour, the cost per unit is approximately NT $ 0.03.

Don't let the low price fool you; if you're producing 5000 a day, it costs NT $ 4500 a month to power the machines.

In 2024, a new energy-saving trick.

Recently, I helped a certain eyeglass factory upgrade its equipment, and found three ways to immediately reduce their electricity consumption:

- Night mode: Automatically switches to a standby mode of 50 watts during non-working hours.

Pulse frequency adjustment: Lowering the power by 30 % when marking shallowly does not affect the result.

Clean the dust: Dust on the fans can increase energy consumption by 15 % or more.
