Providing a consistent solution from selection and development of the optimum cemented carbide material to cemented carbide machining and provision of finished products.
Everloy has been selected as partner by the customers having various issues.
See the reasons to be chosen.

We will solve your problems by providing integrated support from cemented carbide materials to product provision and custom-made cemented carbide products.

we are handling everything from development and selection of cemented carbide materials to precision machining and product provision.We have been active as a manufacturer of cemented carbide materials, but now we are selected as a manufacturer of custom-made cemented carbide products.The cemented carbide products we manufacture are one-of-a-kind products that meet the needs of our customers. We are familiar with cemented carbide materials and have high cemented carbide processing technology. Therefore, we can manufacture high-value-added cemented carbide products that solve the problems of our customers. If you are using general-purpose metals such as alloy tool steel or cemented carbide of other companies and have problems, please contact us once. We promise to make a satisfying proposal.

We identify problems and improvement points through thorough cause and condition analysis, and select the best carbide material.

We not only provide cemented carbide materials based on the requests we have heard from everyone, but also identifies the current problems and improvements through thorough cause and condition analysis.We will select a carbide material that can surely solve your problems.There are various types of carbide materials with different characteristics, and the optimum material differs, depending on the equipment, processing conditions, and product specifications. Therefore, it is essential to identify the cause of the problem, and the process is the most importance in solving the problem. We not only analyze the cause using an electron microscope, elemental analyzer, and X-ray diffractometer, but also confirm the operation at the site and confirm the equipment operation specifications to clarify the cause. After clarifying the cause, we will select the most suitable cemented carbide material that can solve the problem from various in-house developed cemented carbide materials. If you tried everything possible but cannot solve the issue, please contact us.

Support you by Joint development of carbide materials and carbide products.

We produced many materials and new products through joint development with customers.In new product development, there are many cases where existing metal materials and metal products cannot be used.We have cemented carbide material development technology, cause/condition analysis know-how, and precision cemented carbide processing technology, and have all the elements necessary for developing new materials and products. The development phase is accompanied by trials and errors, and the project is long-term. We have fostered a corporate culture of "confronting difficulties and solving unreasonable challenges" and have completed difficult development projects. We will fully utilize our strengths to support the development of cemented carbide materials and products.

Extensive processing equipment and high processing technology,high precision and precision carbide processing unique to cemented carbide material manufacturers

Carbide processing technology is indispensable for manufacturing cemented carbide products. We possess some high quality processing technologies for other than cemented carbide such as SUS and ceramics in difficult and complicated processing, which processing are demanding for outsourcing and requested frequently.In addition, we have electric discharge machines, profile grinders, fluid grinders and others as equipment, which supports processing technology, and realize precision machining. For inspection after processing, we guarantee the quality by inspection with a video measurement microscope and a universal projector.

We achieve large-scale cemented carbide processing unique to cemented carbide material manufacturers, processing up to φ400 x H80 at the optimum cost.

Although there are many processing manufacturers that undertake cemented carbide processing, not as many can undertake large-scale cemented carbide processing, as processing errors made on large scale materials will significantly increase purchase cost which leads to minimal or even loss of profits. As a hard material manufacturer we confidently handle large-sized carbide machining, as well as productions involving complex shapes and high precision, as usually demanded with these large-scale carbides. If you are looking for a processing contractor for large cemented carbide products, feel free to contact us. We can provide one stop support from materials selection/development to product provision.
