Metal products that form the foundation of living culture.
From large products like oil tanks to small items, most of them use molds, and our company has established a manufacturing system for all of these molds. Additionally, we develop a total system from the design and manufacturing of automation systems to assembly.
Utilizing the characteristics of materials expands your lifelong work.
Rubber products are also often seen being shaped with molds. There are various items that take advantage of the properties of rubber, such as soft materials and tools that have strength due to compression. Accordingly, we are planning the development of mold technology to accommodate all kinds of rubber products.
No auxiliary equipment needed! With conventional injection molding equipment, you can achieve a glossy, weldless appearance just like heat & cool.
By placing a thin layer of insulation material 0.5 to 1.0 mm from the surface of the mold, it is possible to deliver the resin, which remains at a high temperature, to every corner. This also improves fluidity, which can help suppress the occurrence of welds and enhance transferability. This can be used in the following situations: - I want to perform molding like heat & cool without additional equipment. - I want to make welds invisible with the current mold equipment. - I want to improve transferability and address short shots in narrow areas. - I want to enhance fluidity and reduce molding pressure. If you have any other inquiries such as "I want to use it for this!" or "Can this also be done?", our representative will respond carefully. Please feel free to consult with us.
We manufacture products that meet our customers' wishes while consistently maintaining quality levels.
We will put our utmost effort into production and will not allow any compromise regarding quality or delivery time.

The introduction of IoT in small and medium-sized enterprises is often carried out in a top-down manner. What is the original purpose of IoT implementation?
According to a 2019 survey by MM Research Institute, the IoT adoption rate among small and medium-sized enterprises with fewer than 100 employees is only 9.5%. Furthermore, a 2018 survey by Nikkei Computer found that while many companies have adopted IoT, the success rate of these systems is only 52.8%. This suggests that many companies are implementing IoT in a top-down manner, and it is likely not being utilized effectively. While a top-down approach is not inherently bad, the original purpose of IoT implementation is to enhance productivity on the ground, innovate management, and ultimately lead to customer satisfaction. Without fostering IT literacy among frontline employees and a willingness to improve the workplace, it is quite challenging to establish and utilize IoT effectively. To those considering IoT implementation: why not adopt our original IoT system that starts small and expands according to your capabilities?
