This time, we used laser processing to create a pseudo pinhole.
Nitrile gloves are used in various situations, but did you know that even when new, they have a pinhole occurrence rate of about 1.2 to 3.75%? Additionally, thin nitrile rubber can easily develop small holes due to minor factors like pulling or friction during use. These holes are called pinholes and pose a risk of direct contact with viruses and bacteria. It is said that pinholes in used gloves are more common on the thumb and index finger of the opposite hand from the dominant hand. Therefore, this processing was performed on the fingertips of the nitrile gloves. Please take a look at the Φ50μm holes that penetrate even the extremely thin nitrile rubber with a thickness of 80μm!

basic information
It is possible to precisely control the position and diameter of the holes being opened, as they are intentionally created rather than accidentally opened. Since it is ultra-short pulse laser processing that is not limited by material, you can create pseudo pinholes in various places, such as insulating gloves.

Company information
At Lips Works Co., Ltd., we provide contract micro-fine processing using ultra-short pulse lasers, as well as the design and manufacturing of laser systems. In our contract processing business, we have been quick to engage in the development of industrial ultra-short pulse lasers and have been involved in contract micro-fine processing using these lasers. We specialize in applying fine periodic structures (microtextures) to work surfaces aimed at controlling tribological properties, optical properties, and release/adhesion characteristics. We can accommodate requests from small-scale prototypes to mass production according to our customers' needs. In our system engineering business, we leverage the laser processing technology cultivated in our job shop to provide a comprehensive service from selecting laser oscillators suitable for applications, designing optical systems, devising fixtures and auxiliary equipment, to system integration. We assist in improving the precision and efficiency of the processing required by our customers. As experts in laser technology providing cutting-edge laser processing techniques, we strive to be a valuable resource for our customers, so please feel free to contact us.
