Mazda makes its production more simple and based on one A multi-solution strategy. A car manufacturer wants to use it to reduce investment and time when preparing a production line for the production of a new type of car. The OEM has its own production line for this The H2 has been rebuilt in Japan’s Hofu factory. This is also due to the fact that the Japanese have announced the expansion of their model range from 2022 with the new Mazda CX-60 and CX-80 models.
In addition to the Mazda6 and Mazda CX-5 models currently produced in Hofu, larger cars based on the new. Big Platform Architecture be made with various electric drives. This should be facilitated by an improved production system: The latest example of Monotsukuri Design in Mazda production will ensure that it will be easy to transfer production to new models in the future or adapt it to changing needs, Mazda says. Monotsukuri represents the creation of objects with special technical skills and knowledge.
In the factory, cars go easily on pallets
After the conversion, cars with different sized platforms, drives and engine configurations (transverse or longitudinal installation) could be produced on the line in the future. The heart of the modified production line is the bypass dolly line: Instead of using conveyor belts or monorails, cars are moved on pallets driven on trolleys on the ground level. According to Mazda, these are more flexible than a complex system, and the production line can be easily expanded, thereby increasing production capacity. In addition, employees can freely move around the platforms and carry out activities in the respective vehicle. Two automated guided vehicles (AGVs) accompany the model currently in development and provide motors and suspension for the front and rear wheels – or batteries in electric models.
In the body welding plant, the new flexible module line should contribute to shorter lead times and lower investment costs, especially when expanding the product range. “Instead of repeating the process of dismantling and building a new one with each new model, with a simple series of modules we only need to change the jig to attach the parts.said Takeshi Mukai, Chief Executive Officer of Mazda Motor Corporation. Thanks to innovations in the body line and assembly of the car, this process can now be done in around a fifth of the time and ten percent of the investment costs compared to conventional systems, according to Mazda.
