We provide one stop solutions from selection and development of the optimal cemented carbide material to machining and provision of finished products.
See below the reasons as to why Everloy has been selected as partner by customers having various issues.

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

We provide one stop support from development and selection of cemented carbides to their precision machining. Having a long history as a cemented carbide materials manufacturer, we are now a manufacturer of choice for custom-made cemented carbide products and supply one-of-a-kind products that meet our customers' requirements. These high value-added cemented carbide products can be manufactured thanks to our expertise in cemented carbide materials and advanced machining technology for these materials. In case you are facing troubles with using general-purpose metals (alloy tool steel esc) or cemented carbides of other companies, please contact us and we will guarantee to make a proposal that will satisfy your requirements.

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

As for selecting the cemented carbide materials that will reliably solve the problems our customers face, we do not base our decision solely on their requests; we also base on our findings from our causes and conditions analysis which will identify the current problems and the areas for improvement. There are various types of cemented carbide materials with different characteristics, and the optimal material will depend on the processing equipment, processing conditions, and product specifications. Therefore, identifying the causes is always imperative in approaching the problem. We not only analyze the cause of the problem using electron microscopes, elemental analyzers, and X-ray diffractometers, but also check on-site operation and confirm equipment operating specifications to determine the cause of the problem. Once the cause is identified, we will select the most suitable cemented carbide material that can solve the problem from various cemented carbide materials developed in house. We will support you with any difficult or persistent problems you are facing.

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 machining technology is essential for manufacturing quality cemented carbide products. In difficult and complex machining, we possess the technology to accept tasks of machining materials other than cemented carbides such as stainless steel and ceramics. In addition, as for equipments that support our processing technology, we have EDM Machines, profile grinders, abrasive flow machines and other equipment to achieve precision processing. For post-processing inspections, quality is assured through inspections using digital video microscopes and universal projectors.

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.
