'Spifox' Soars to World No.1 with Aluminum Capacitor Cases

[Asia Economy Reporter Donghyun Choi] In 2019, when Japan restricted exports of three key semiconductor and display items to Korea, the industry was put on high alert. There were concerns that major domestic companies like Samsung Electronics and LG Display might have to shut down their factories. Last year, a shortage of urea solution from China caused the 'urea solution crisis.' This led to nationwide fear that diesel engine vehicles such as cargo trucks, fire trucks, and ambulances could come to a halt. Recently, supply instability in carbon dioxide, aggregates, cooking oil, and flour has caused damage to the overall Korean economy.

When a country or company holds a monopoly over certain raw materials, products, or technologies, the importing countries or companies inevitably find themselves in a subordinate position. Korea, lacking significant natural resources, must overcome these structural limitations solely through technological prowess. This is why a sense of crisis and mission to secure 'super-gap technology' is spreading throughout the domestic industrial sector.

Spifox Dominates the Global Capacitor Case Market

Amid this, a small but strong company that has risen to the top on the global stage with outstanding technology is drawing attention. It is 'Spifox,' located in Moga-myeon, Icheon-si, Gyeonggi Province. Spifox holds the number one global market share (55%) in surface-mount device (SMD) type aluminum electrolytic capacitor cases. Yongrae Kim, CEO of Spifox, stated, "Once the 100% inspection technology to reduce product defect rates is completed, our market share will grow to over 75%. This means that if our factory were to shut down, it could shake the global semiconductor market," expressing confidence.

Founded in 1985, Spifox surpassed the Japanese market leaders with technology that maximizes production efficiency of aluminum, the raw material for capacitor cases. Japan used a method of processing aluminum sheets as a whole to make cases. However, Spifox developed a technology that first cuts the sheet into coin-shaped pieces and folds them into cup-shaped semi-finished products, then applies pressure to form the cases. This method allows more cases to be produced from the same area of aluminum sheet. Hyojin Kim, Executive Director of Spifox, explained, "With our unique technology, we achieved about a 30% cost reduction based on 6-pie capacitor cases."

In 1999, Spifox also became the first in the world to develop a technology to coat capacitor cases with polyester (PET) film. This was a technology Japan initially tried to develop but abandoned. Japan attaches nylon instead of PET film to the cases. Both methods aim to improve insulation and heat resistance. CEO Kim studied Japanese products by disassembling them and devised a technology to coat PET film on cases using heat and pressure. Kim emphasized, "In discoloration tests conducted by heating at 150 degrees Celsius for over 5,000 hours, nylon discolored but PET cases remained unchanged. PET is environmentally friendly because, unlike nylon, it biodegrades when buried."

Overcoming Court Receivership Pain to Develop Smart Process Independently

Typically, small and medium enterprises lack the capability to develop smart processes independently and often outsource them. However, Spifox developed a smart process system covering the entire production line, including product manufacturing, cleaning, heating, and defect inspection, on its own.

CEO Kim's motivation to introduce the smart process system came from the painful experience of court receivership (corporate rehabilitation). Spifox entered court receivership in 2014 due to worsening cash flow and losses from its Chinese subsidiary and exited in 2017. During this period, Kim deeply considered reducing labor costs and improving productivity. He had to choose between building a factory in Southeast Asia, where labor is cheaper, or introducing robots in the domestic factory. Kim ultimately decided to introduce robots, marking the beginning of Spifox's smart process. He recalled, "When I said I wanted to buy robots without repaying borrowed money, the bankruptcy trustee judge was puzzled. I persistently persuaded the judge that although orders were coming in, there were no workers, so we would make products with robots to repay the money, and eventually got approval."

A robot located on Spifox's smart production line is moving a bin containing aluminum cases.

Since then, Spifox has steadily introduced smart processes and now has the capacity to produce 40 to 70 million capacitor cases per day. Sales increased from 15.3 billion KRW in 2019 to 22 billion KRW last year. This year’s sales target is 26 billion KRW, with a goal to surpass 30 billion KRW next year.

Spifox is currently developing a system that automatically inspects all produced cases. Currently, most companies including Spifox sample a portion of the day’s production to check for defects. If even one defective product is found among 10 million units, the entire batch must be discarded. However, with the full inspection system, only defective products will be filtered out. CEO Kim said, "The development of the full inspection technology is 90% complete. Once completed, this technology will change global industrial trends."

Transforming Aluminum Scrap into Building Materials

Spifox's 'Papaya System'.

Spifox recycles about 60 tons of aluminum scrap leftover from making capacitor cases each month into building materials instead of discarding it. The building material is called the 'Papaya System,' a heat-conductive panel for ondol (Korean floor heating) made of perforated aluminum sheets coated with copper plating and special anti-corrosion coating.

Applying the Papaya System has proven a 22% reduction in hot water heating energy consumption, earning carbon emission reduction certification from the Ministry of SMEs and Startups and the Ministry of Environment. Hyojin Kim, Executive Director of Spifox, explained, "The Papaya System reduces heating costs by about 180,000 KRW annually for a 30-pyeong apartment. It not only recovers installation costs but also reduces carbon emissions by 633 kg per year."
