We would like to introduce a case regarding the development of a coater device that can use two heads. The request this time was for a roll coater that can use both a comma head and a die head. In the case we are presenting, we decided to forgo the "unit exchange type" because we wanted to minimize human operation during exchanges and reduce risks such as accidents. What the development team came up with was a method that encapsulates the unit, as shown in the image. Since it does not require optional parts and is quite reasonable in terms of cost, the customer was very pleased and decided to adopt it. 【Case Overview】 ■ Customer: Company ■ Application: Prototype of a battery ■ Request: A roll coater that can use both a comma head and a die head *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where we added a drying oven to a roll coater as an after-installation at our company. In the initial design, the drying oven was configured with two units, but during use, we received a request to "add a drying oven." In response, we decided to add the drying oven after the completion of the equipment. The Sankmetal coater has a modular design for the drying oven section, allowing for the unit to be split and new units to be added even after the equipment is completed. The design allows for the addition of up to six drying ovens to a single coater, accommodating needs like the one mentioned.

We would like to introduce a development case conducted by our company using the strip method. Unlike the winding method, the strip method requires manually pushing the material close to the roll. At this time, to prevent hands from getting caught in the roll, a safety cover is installed at the material's entry point. Normally, this specification meets safety measures, but the company we are introducing this time requested even higher safety standards. We considered whether it was possible to create a system that would eliminate the need to bring fingers close to the roll in the first place. This led to the creation of the roll press with a slider. [Case Overview] ■ Customer: Company ■ Application: Prototype of a battery ■ Request: To implement thorough safety measures to prevent hands from getting caught in the roll press *For more details, please download the PDF or feel free to contact us.

Our company established the second and third factories within the premises of our first factory in Kato City, Hyogo Prefecture, in June 2023 to expand our manufacturing capacity for battery prototype equipment and the supply of expanded metal. With the increasing demand for battery prototype equipment against the backdrop of the proliferation of EV cars, inquiries from many companies and research facilities have been rising, as our coaters and press equipment can be utilized not only for battery component prototypes but also for other applications. In response to this, we are adding new machining centers to our existing factory and expanding the factory within the premises of our first factory to aim for an increase in equipment supply, enabling us to accommodate the manufacturing of large-scale equipment. Expanded metal is a mesh-like metal material originally developed by our company, and it is used in various applications beyond battery components, including sports goods, computers, and precision machinery parts. Previously, processing was done only at our Miki factory in Hyogo Prefecture, but recently there have been cases where it is also used in building materials, prompting the decision to expand the factory within the premises of our first factory. *For more details, please refer to the related links or feel free to contact us.*
