Is a 50-ton die-casting machine actually an electricity guzzler? Consuming 600 kWh of electricity per day is astonishing

When Mr. Zhang saw the factory's electricity bill for the first time, he almost jumped out of his chair - the monthly electricity bill for a 50-ton die-casting machine was actually as high as five digits! This can't help but make people curious: How exaggerated is the electricity consumption of a medium-sized die-casting machine? Today, we will dismantle this industrial electricity black hole that is ignored by most people.

The 50-ton die-casting machine, as a standard equipment in small and medium-sized production lines, its power consumption mainly consists of three parts:

• Power of the main motor: Usually 15 - 22 kW, which is equivalent to running 300 household computers simultaneously
• Power of the heating system: About 9 - 12 kW, the core energy consumption for maintaining the temperature of the molten metal
• Power of the auxiliary equipment: Including the hydraulic system, cooling devices, etc., about 5 - 8 kW

The measured data of the Zhongshitong technical team shows that under the continuous production state, the comprehensive power consumption of this type of equipment is about 30 - 40 kWh per hour, which is equivalent to the electricity consumption of an ordinary family for three days.

Assume that the equipment works 20 hours a day (including 4 hours of standby):

• Production period: 16 hours × 35 kWh/hour = 560 kWh
• Standby power consumption: 4 hours × 8 kWh/hour = 32 kWh
• Total daily electricity consumption: 592 kWh (Calculated at the industrial electricity price of 0.8 yuan/kWh, the daily electricity bill is about 474 yuan)

It is worth noting that Ms. Li's factory once had a 20% surge in electricity consumption due to mold aging, which reminds us that the impact of the equipment maintenance status on energy efficiency is far beyond expectations.

1. Optimization of production scheduling: Avoid energy losses caused by frequent start-ups and shutdowns. Batch production saves more electricity.

2. Intelligent temperature control system: Installing a PID temperature controller can save 15% - 25% of electricity.

3. Valley-peak electricity usage strategy: Utilize the low-tariff period at night for high-energy-consuming operations.

A customer served by Zhongshitong successfully reduced the monthly electricity consumption of a single equipment from 18,000 kWh to 14,500 kWh through the above combination of schemes, saving more than 30,000 yuan in annual electricity bills.

When we convert the daily electricity consumption of 592 kWh into carbon emissions, it is equivalent to burning 237 kilograms of standard coal every day. Today, when green manufacturing has become a global consensus, saving every kWh of electricity is an investment in the future. Has your factory ever conducted a detailed energy consumption audit?
