<Price and Order Lot> - As a guideline, the unit price can start from several dozen yen per piece, but since production will be on a razor production line, the order lot size will be large, requiring orders of several thousand pieces or more at a time (it is difficult to accommodate small production runs of several to several dozen pieces on the production line). - Depending on the shape of the blade body, it may be necessary to create a separate press die for the blade body. <Development and Quality Assurance> - Kai Corporation has a well-established development and quality assurance department, so we can meet your high demands. <Inquiries and Business Negotiations> - Please feel free to contact us first. A Kai Corporation sales representative specializing in industrial blades will be your point of contact and will provide you with courteous assistance.

It will be a high-precision industrial blade utilizing razor blade technology. Please select according to each type and the machine installation. *For inquiries, please feel free to contact us through our website.

Here is an introduction to a case study of a major textile factory that introduced KAI's "carbon fiber cutting blade." In the manufacturing process of carbon fiber reinforced plastic (CFRP), we developed a blade to finely cut carbon fibers as thin as human hair. Our goal was to extend the durability and prevent fiber remnants, and after about a year of trial and error and extensive testing, we achieved results that exceeded our initial durability target by more than three times. With stable machine operation now possible, we were able to realize cost reductions, which greatly satisfied our client. [Case Study] ■ Implementing Company: Major Textile Factory ■ Customer's Challenges - The blades previously used had a short durability. - There was variability in blade edge quality, leading to instability in the cutting process. *For more details, please refer to the related links or PDF materials, or feel free to contact us.

We would like to introduce a case study of a major automotive seat polyurethane foam factory that has implemented the "urethane sheet cutting blade" from Kai Corporation. The customer's request was to achieve a blade that cuts smoothly and effortlessly. During the development phase, it became clear that thin and soft polyurethane is a very difficult material to cut. After about six months of trial and error and repeated testing, we sharpened the blade angle and applied a fluorine coating. As a result, we were able to develop a blade that cuts smoothly, greatly improving work efficiency, and the customer was very satisfied. [Case Study] ■ Implementing Company: Major automotive seat polyurethane foam factory ■ Customer's Challenge - The burrs generated during the molding of polyurethane cannot be cut off with a dull blade. *For more details, please refer to the related links or PDF materials, or feel free to contact us.

We would like to introduce a case study of a major polarizing film manufacturing factory that implemented the "polarizing film cutting blade" from Kai Corporation. We developed a blade for cutting polarizing films used in LCD TVs and smartphones. Since polarizing films are made of very hard materials, we conducted extensive research on what angle to set the blade tip. Additionally, because fine chipping can lead to product defects, high process management was also required. As a result, we successfully developed a highly durable blade that does not compromise the high picture quality of LCDs. The durability far exceeded our customer's expectations, leading to significant cost reductions. [Case Study] ■ Implementing Company: Major Polarizing Film Manufacturing Factory ■ Customer's Challenges - A high-quality blade tip is necessary because the cutting surface affects picture quality. - High durability is required. *For more details, please refer to the related links or PDF materials, or feel free to contact us.

We would like to introduce a case study of a major chemical film manufacturing factory that implemented the "Special Film Cutting Circular Blade" from Kai Corporation. A circular blade was developed for slitting special films. This special film is thin, but very high quality was required for the cutting edge. Since the circular blade has edges sharpened on both sides all around, it is difficult to create a clean edge without chipping. After much trial and error, a high-quality circular blade with excellent sharpness was completed. The reduction in product defects led to significant cost savings. [Case Study] ■ Implementing Company: Major Chemical Film Manufacturing Factory ■ Customer's Challenge - The circular blades previously used had edges with fine chipping, resulting in product defects. *For more details, please refer to the related links or PDF materials, or feel free to contact us.

We would like to introduce a case study of a major printer equipment manufacturer that has implemented the "Large Printer Built-in Cutting Circular Blade" from Kai Corporation. Paper is a very tough material for cutting tools. Not only is there the issue of paper dust, but the load on the cutting edge is also significant, making it difficult to achieve durability with this material. During the development process, we formed a joint development project team with the customer, repeatedly testing with prototype blades and holding development meetings. As a result, a blade with the highest possible grinding precision was completed, solving the problem of paper dust. [Case Study] ■ Implementing Company: Major Printer Equipment Manufacturer ■ Customer's Challenge - How to reduce the amount of paper dust generated during the cutting of photographic paper *For more details, please refer to the related links or PDF materials, or feel free to contact us.
