LIPSS processing was performed on an S45C extrusion molding die using an IR laser.
We processed a nano-periodic structure with a 900nm pitch on the inner lip surface used in tube molding, etc., using an ultra-short pulse laser. The structural color unique to LIPSS processing is manifested in the tubular part of the mold tip.

basic information
I believe that blast processing and plating on mold surfaces have already been utilized to expect fluidity and peelability, but this time we propose a new method of surface processing using lasers. By performing ultra-fine processing to make the flow path through which the resin passes horizontal during extrusion molding, it may lead to improved fluidity...? Of course, processing on molds made of other materials, as well as processing of different shapes such as dimples and grooves, and LIPSS processing for decorative purposes on metal products and molds are also possible.

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.
