Design/reliability

This is a constant temperature/constant humidity built-in chamber. This creates an environment of -40 to +80°C and 10 to 95% rh, which we use in product design. Sized large enough to take one small bike, we are able to collect various types of test data.
These instruments are for thermography to measure the state of temperature distribution. Apart from these, we use various instruments such as temperature recorders, etc., to develop highly reliable products.
サーモグラフィ
This is a “knee” endurance testing machine. The company’s products are characterized by being “thin and flexible”, but they are designed so that they also have strong endurance. This is a testing machine with a “knee-like” part attached to verify durability.

Equipment

This is automatic wiring equipment. It is able to wire products with freedom using CAD/CAM data. A patented “Heater wire contact alarm device” is attached to the equipment, enabling us to prevent the outflow of defective products. Products can be wired freely up to a width of 1,100 mm.
This is cutting equipment. It is able to cut products in complicated configurations.
This is specialist turntable-type equipment. We also have a lot of other specialist equipment apart from this.
