Low frequency of air conditioner is changed to high frequency, magnetic powder core ushers in demand

At the beginning of 2020, in addition to the medical market, production in many other industries was sluggish and demand was urgent. Especially in the home appliance industry, due to the objective reasons of the home economy, the demand for products such as traditional home appliances and small home appliances has increased significantly compared with previous years.

MPCO Magnetic Device Co., Ltd. is a magnetic material company specializing in the supply of magnetic devices. It independently develops, produces and sells iron-nickel, sendust, sendust, iron-silicon, sendust, super sendust series of products, with an annual output value of 400 million yuan. Products are widely used in home appliances, new energy vehicles, charging piles, UPS, inverters, 5G communications, rail transit, new mining machines and other fields.

Among them, home appliances are an important terminal scenario for its products.

Eric, general manager of MPCO, told reporters that due to the impact of the epidemic at the beginning of this year, their orders were relatively sluggish. Fortunately, after the first quarter, demand rose sharply in the second and third quarters. In addition, in the home appliance market, due to changes in the application technology of home appliances, especially the change of low-frequency to high-frequency air conditioners, this has triggered a wave of demand for metal magnetic powder cores.

Eric believes that this kind of technological change, on the surface, is a change in application, but in essence it is to strengthen the awareness and requirements of enterprises in terms of energy conservation, environmental protection, and high efficiency in production. “As far as air conditioners are concerned, silicon steel sheets were used in low-frequency air conditioners in the past, which are characterized by large volume, high energy consumption, and high noise. After changing the application design, replacing silicon steel sheets with metal magnetic powder cores should have an immediate effect. Compared with, after interviewing this material, the product has the advantages of reduced volume, reduced weight, reduced energy consumption, and low noise.” In this case, the ring-shaped aerosolized iron-silicon mainly provided by MPCO Products such as aluminum and iron-silicon cores just meet this market demand. air conditioner magnetic powder core

Since the second half of this year, the demand in the home appliance industry has increased significantly. Some supply chains are facing serious shortages, and some enterprises are even more overwhelmed by the sudden surge in orders.

As an upstream supply chain, Encore has the ability to undertake urgent orders and large orders. In terms of production technology, MPCO has a series of production technologies and supporting equipment for powder making, coating, molding, annealing, impregnating, sorting, and coating. In terms of equipment layout, there are more than 70 sets of forming presses ranging from 20 tons to 1250 tons, and the processing size is from 6.6mm to 101.6mm.

At present, it has a daily production capacity of 20 tons of alloy powder (equipment is being updated now, and it is expected to reach the daily production level of 30 tons of alloy powder by the end of the year), forming and processing 29 tons, and the highest annual production capacity can reach 8,000 tons. “Due to the above-mentioned multi-material, large-capacity, and wide-size product supply, it will basically not cause an overwhelmed situation.” air conditioner magnetic powder core

“In addition, affected by the epidemic, trade policies, technology blockade, etc., some foreign orders have turned to China, which has given us great opportunities in terms of localization level and demand for magnetic materials. In the future, our industry will gradually break the monopoly of foreign countries. , to further increase the proportion of domestically produced magnetic materials.”

At the same time, the repatriated companies also include their peers. They have suffered setbacks in overseas markets, and they have also returned to China. The price has dropped again and again, squeezing Encore’s profit margins, resulting in disorderly competition this year. In terms of quality requirements, the terminal also puts forward ultra-conventional magnetic core performance requirements for magnetic material manufacturers, and MPCO must also produce products that strive for excellence, which is followed by an increase in costs.

On the other hand, the raw materials of magnetic materials are greatly affected by the futures market this year, especially the price of ferrous and non-ferrous metals has risen rapidly, which has also formed a trend of squeezing the profit cost of magnetic material enterprises.

In the face of opportunities and various challenges, Eric said that the most important thing for them is to practice their “internal strength” and cope with pressure by improving production efficiency and reducing the defect rate. And resolutely seize the opportunity of market development, and make up for the squeezed profits through large-scale production.

Eric believes that in the next few years, due to the advantages of high efficiency, high frequency, and durability, metal magnetic powder cores are very likely to replace some manganese-zinc and amorphous materials in some fields, and the market space will continue to expand. MPCO is also actively meeting the needs of the rapid development of the market and constantly improving itself. At present, they are updating powder smelting equipment, increasing production capacity, and are preparing to further strengthen automation transformation, improve production efficiency, improve product quality, and reduce manual work intensity.
