Cataler Technology

Meeting Diversifying Needs with Long-standing Technical Know-how and Technological Development

R&D System

Meeting Customer Needs with Internal/External R&D System and In-house Development Process

We work with universities and external research institutes at the R&D stage, and material manufacturers at the product design stage in ongoing efforts to propose products that exceed our customers' expectations. Cataler also promotes V-model from material development to actual vehicle evaluation.

Production Technology

Production Technology System

Slurry is tuned, mass-production technology is developed, processes are evaluated, and facilities are established in order to realize the production of newly developed catalysts. Along with promoting the development of new methods to further boost performance and breakthrough cost reductions, our production technology and R&D experts are brought together to form a single organization.

Development of Methods for Stable Quality and Production

We have developed and are globally deploying the ZECT coating method, a high quality, high cost performance technique that fuses various basic technologies including state stabilization, slurry fractionation, and flattening to ensure even coating width.
Furthermore, an initiative aimed at creating high-quality, highly mobile compact facilities for developing nations with increasingly stringent exhaust regulations - is being promoted.

Development of Traceability System

We have developed a traceability system not only for quality data, but also process conditions to ensure customers only receive reliable products they can trust. Searching for a product ID brings up data about the catalyst materials it's composed from, the amount of precious metal used, unit conditions during manufacture, and other information vital for guaranteeing the quality of each and every product
