Their recipe for building trust for CCW

Ishida’s long history in the world of weighing began in 1893 when they became Japan’s first private weighing equipment manufacturer during a new age of industrial modernization.

Initially introduced for food product applications, computer combination weighing (CCW) is now an indispensable technology across a wide range of markets. Ishida’s fixed quantity weighing solutions are the product of choice in virtually every sector, from dry and frozen food to fresh meat, poultry and fish, pharmaceuticals, and industrial parts.

The Ishida development department has long operated with the spirit of "(W)hat you need to see is always in the customer's factory," according to Hideshi Miyamoto, Ishida Deputy General Manager R&D, who has been instrumental in the development of Ishida's weighing machines. Ishida strongly believes that close partnership with customers provide significant steps forward in development. This also leads to customer satisfaction and product innovation.

Factors to consider when developing multihead weighers

A multihead weigher is a measuring instrument therefore accuracy is the premier factor and a requirement for productivity. Ishida develops their machines with the goal of leading the industry in accuracy. In addition, hygienic design features are essential to help with sanitation procedures. As Ishida expanded into more markets, the need for waterproof design was evident. In the production environment for wet products, machines are washed with high-pressure and chloride water, so Ishida incorporates design elements that minimize the risk of aluminum rusting and the risk of contaminants entering the food chain.

Ishida multihead weigher distinctions

Ishida was the first company in the world to develop a multihead weighing machine, and as the pioneer of multihead weighers, they are confident that their weighers will never lose weighing accuracy, unlike other weighing machines. The next generation model, the CCW-AS series, achieves an internal calculation of ±0.01g weighing accuracy along with improved hygiene and minimized water ingress, and the IP69K design accommodates a wider range of products. The CCW-AS also improves product feeding for sticky wet products.

The future outlook for weighing machines

Ishida continues to explore ways of improving their products and has been developing technology in collaboration with various universities as part of open innovation.

Ishida appreciates the trust from their multihead weighing machine customers and hopes to continue for the next 50 years to develop machines that improve productivity and that contribute to food safety and security and to continue responding to the trust given them by their customers, not just as a supplier but as a reliable partner.
