01 / ABOUT DIH GANG

Start with the material.
Build the right knife for the production line.
Knife manufacturing and grinding expertise,
working together for your production line.
Based in Fengyuan, Taichung, Taiwan, DIH GANG KNIFE INDUSTRIAL CO., LTD. manufactures industrial cutting tools for paper, plastics, footwear, fibers, metal, bamboo and wood applications. We review your workpiece material, equipment and knife dimensions to understand how the tool will be used.
Different materials and cutting methods call for different blade materials, angles and profiles. Drawing on material analysis and knife-making experience, we discuss carbide and custom knife specifications from engineering drawings or samples, helping you define a suitable manufacturing approach.
By integrating Qing Feng’s machining capabilities, we bring knife manufacturing, surface grinding, double-sided grinding and polishing together. Our 23 German and Japanese grinding machines support this coordination, and we also welcome inquiries for workpiece grinding.
Whether you need an existing knife profile, custom tooling or component grinding, send us your material details, drawings or samples. Dimensions, tolerances, surface requirements and quantities are reviewed before we confirm the machining method and delivery schedule.
