Senior engineer, Deputy Director of Marketing
Sichuan Shen Gong Carbide Knives Co., Ltd.
Sichuan Shen Gong Carbide Knives Co., Ltd. is located in Sichuan Province, Chengdu City, in the southwest airport development zone Shuangliu. It developed from its predecessor Chengdu Siruite Carbide Knives Co. Ltd. to its current form and now covers 29,000㎡ (building area is about 25,000㎡) and employs 300 people in total. The company boasts an integral production line ranging from WCP preparation to finished carbide knives/blades. Their machine park features more than 500 machines.
Asian Metal: Good afternoon, Mr. Nori Nishikawa. Thank you for your time to accept our interview. Would you please introduce your company?
Nori Nishikawa: With more than 20 years of experience in the production of tungsten carbide cutting and slitting knives/blades, our company specializes in corrugated board cutting blades and other circular blades. More than half of our products are used in the overseas markets. Our corrugated board cutting blades of our brand "Jingrui" won the "Technologies Innovation Awards" of Sichuan Province. Our "SRT" (Shen Gong Royal T) blades used for cutting lithium battery poles as well as our industrial blades are leading both in the domestic and global markets. Shen Gong qualities meet highest standards and requirements.
We want to prove that as a Chinese manufacturer, we are a quality maker of the 21st century with excellent products, just-in-time deliveries and great customer service. We believe in product development, sustainability, eco-friendly production and long-term customer relationships.


Asian Metal: As the tungsten market was stagnant in the last five months, could you please discuss about the downstream demand for cemented carbide cutting tools recently? Which kind of products you think will have better prospects?
Nori Nishikawa: Since tungsten price is settled at lower price, most of cutting tool manufacturers are fine to make any geometries of cutting tool inserts with lower cost. However, in future if the price goes up again, they need to consider replacing metal binder with other metal like nickel, instead of cobalt.
Also, they are considering to expand their business with other material grades, such as ceramics, silicon nitride, cermet and so on which do not use tungsten carbide. Turning inserts and milling inserts are very popular items for cuttings tools, but now, some multi-purposed inserts with function of turning, milling, and grooving, will be more popular in the future.


Asian Metal: As we know, many Japanese companies have decreased the import volume for tungsten products, and could you please briefly introduce the Japanese tungsten market so far this year?
Nori Nishikawa: By predicting Japanese market, we need to consider three main issues. The first is trade war for automotive and agricultural products against USA, the second is that Japanese government debt is highest ever, and the third is labor shortage due to less young generation’s population. According to these issues, most of economists predict our economy growth will be less than 1.0 % this year, along with consumption tax increase from 8% to 10% within this year announced by government to increase tax income due to labor shortage.


Asian Metal: Could you please introduce some new technologies on cemented carbide you have researched? What are their advantages?
Nori Nishikawa: Our engineer team is always striving better way to improve static/physical properties of cemented carbide grades we produce. We are searching mainly for metal binders including not only nickel and cobalt, but also other metals. And another issue will be the grain sizes of tungsten carbide as raw material. It is hard for any tungsten carbide manufacturers to keep certain hardness with fracture toughness or transverse rapture strength, but we are trying to find some ways to reach this goal, by combining other carbide materials.
