TSK: A trusted partner to automobile manufacturers

Article - October 13, 2023

For nearly 50 years, TSK CO.,LTD. has played a key role in the manufacturing of car parts, offering expert mold manufacturing and product design.

TOSHIO SAKODA, PRESIDENT, TSK CO., LTD.

“Prioritizing customer satisfaction over making a profit is a recipe not only for a happy customer, but also a happy company.”

Toshio Sakoda, President, TSK CO.,LTD.

Founded in 1977, TSK CO.,LTD has established itself as a go-to manufacturer of molds for rubber and plastic automobile parts, with specialization in component design. Based in Komaki City, the Japanese company boasts particular expertise in rubber weatherstrips, the protective seals fitted around the edges of vehicle doors, windows, windshields and trunk lids. 

With overseas factories in China, Indonesia, Mexico, and Thailand, TSK has a strong international presence. To counteract Japan's population decline, the company is increasingly expanding its operations abroad. “To cope with the shrinking domestic market, we’re trying to expand our market share overseas,” says TSK’s president, Toshio Sakoda. “In 2018, we started operations in India. We’re also considering expanding into African markets such as Nigeria.”

Mr. Sakoda continues: “Japan's decreasing population has resulted in a shrinking labor force. To address this, we're automating our manufacturing processes. Additionally, we're considering hiring foreign workers to overcome the shortage, but automation is our current priority.”

As TSK CO.,LTD charts its course for the future, the company is committed to playing its part in achieving Japan’s goal of carbon neutrality by 2050. “We strive to contribute to a better society,” Mr. Sakoda says. “As part of our push for carbon neutrality, we’re certified by the Science Based Targets initiative until 2044, and we’ve created a roadmap based on activities that work towards becoming carbon neutral.”

Alongside electrification, the use of lightweight materials is a key focus of the automobile industry’s efforts to make vehicles more environmentally friendly. TSK CO.,LTD  remains dedicated to meeting its clients’ needs when it comes to moving away from rubber, Mr. Sakoda says, but he adds that manufacturers face a challenge to make equally effective weatherstrips from lighter materials.

“Rubber has traditionally been used for weatherstrips, but it’s heavy and difficult to recycle and reuse,” he explains. “Resin, on the other hand, is lightweight and easy to mold. However, in terms of the performance of the product itself, rubber still has several advantages.”

In addition to its drive to promote a greener future, TSK CO.,LTD is focused on developing equipment that allows it to manufacture its products with greater and greater precision. “We receive an R&D grant from the Japanese government,” Mr. Sakoda says, “and we’ve been using it to invest heavily in innovating our processing technology. The accuracy our clients demand is increasing day by day.”
