Nissei, Recruiting for PLB licensee manufacturers

Nissei Co., Ltd. (Yamanashi), a rolling machine manufacturer, has begun recruiting Japanese companies that have a license production contract for the locking bolt "PLB" (Perfect Lock Bolt). The company supplies rolling dies to licensees.
PLB has a double nuts structure, and a single bolt has a fine and coarse double thread structure. Fine nuts and coarse nuts can be mounted on the same axis.

When two types of nuts with different pitches are provided by vibration, a fine nut that is slow in advance even with the same rotation will physically prevent loosening by holding the coarse nut on the inside of the fast advance.
Because it is formed by rolling, it has about twice the strength and durability compared to the same specification made of cutting bolts.
The company has signed PLB license agreements with overseas companies several years ago, and has begun overseas production in the United States and Turkey. PLB is often used in mechanical fields with high vibration such as mining machinery, agricultural machinery, and belt conveyors.

The President of Toshinaka Shinfutsu shows confidence that PLB has been adopted in these fields, saying that “the ability to prevent loosening of PLB stands out because it is in an extremely severe environment with severe vibrations”.
This time, in order to expand the production of PLB to manufacturers in Japan, They will start full-scale efforts for a license agreement.

Nissei is responsible for the production of rolling dies, which is a core technology that is difficult to produce, and supplies dies to licensees.
Equipment that can be mass-produced has been introduced in its own factory. They have already established mass production technology with cylindrical dies, but are currently developing technology to produce PLB with flat dies.


The joint sales plan of Japan Socket Screw is 5.4 billion yen.

Japan Socket Screw Industrial Cooperative Association (Chairman Tokuo Hiraguri = Alps Seiko Co., Ltd.) held the 43rd General Meeting in Nagano Prefecture on May 23. The joint sales plan is planned to increase by 4.7% to 5.4 billion yen in the previous fiscal year in anticipation of the shift from labor saving to a smart factory and the activation of socket screw industry following Tokyo Olympics and economic recovery.
In the business report of 2018, there were the following reports on socket screw industry.

The machine tool industry grew 19% annually, although the pace slowed slightly at the end of the year due to active orders. Our cooperatives also increased by 13% to 5% until the end of last year, but fell by 7% from January to March from the end of last year, and achieved about 5.3 billion yen last year, achieving the target 5.5 billion yen could not.


Tsukiboshi rebuilding headquarters factory with 2 billion yen investment

Tsukiboshi Co., Ltd. (Ishikawa) sales in FY2018 were 12,634 million yen, down 0.8% from the previous year. The headquarters factory will invest 2 billion yen to reconstruct the entire factory through new reconstructions and layout revisions.
Orders from the second half of the fiscal year decreased due to sluggish vehicle sales in China due to US-China trade friction. Ordinary income decreased 31.6% year on year. Labor costs, soaring material prices, and repair costs put pressure on profits.
Tsukiboshi plans to generate 13.5 billion yen or more in the next fiscal year, while developing technological strengths and developing new orders for high-quality products.

However, there is no growth in orders, and President Wataru Uchimoto said, “I am concerned about the cooling of the Chinese market. I want to secure profits.” On the other hand, the long-term goal of sales of 15 billion yen by 2022 will remain unchanged.
The future plan is to rebuild the headquarters factory with the theme of “Tsukiboshi Innovation”.

Based on the concept of “factory layout with an eye on 10 years ahead,” the company plans to send the products produced in each factory building through the central arcade that prevents rain and to collect and ship them to a “delivery / inspection center”.
A new factory building with “delivery / inspection center” and NC lathe will be newly established.

Tsukiboshi will review the entire factory to optimize the flow of human and objects, such as expanding and renovating existing factory buildings.
The total investment will be 2 billion yen, aiming for completion in 2 years while operating the factory.

At the headquarters factory, in March last year, they renovated the development room with departments that required flexible ideas, such as the production engineering department and development department, and built a cafe space and free address system aimed at promoting communication.
