Product Inspections
Make no defects, miss no defects.
Our responsibility and pride in quality throughout our processes
Hiraoka Body fuses continuous operation of international quality management standards (ISO-9001) and our own proprietary initiatives to continue our stable supply of products. In particular we have pursued the best possible quality at each facility by thoroughly managing 4M (material, machine, man, and method) which are the fundamental elements of manufacturing, and under the slogan “We will not produce and pass down inferior products!”. We also accumulate and use a vast amount of product data from the prototyping stage to the mass production stage, and repeat feedback for metal molds, jigs, and tools to support the smooth start of mass production.
Non-contact 3D measurement
We employ three-dimensional measuring machines primary to assure the quality of mass produced components. Our three-dimensional measuring machines are of high precision stationary molds and non-contact handy measurement devices that are capable of speedy measurements. They can measure values up to 1/1000 mm. We utilize this machine to accumulate data on a daily basis. It allows us assure consistent product precision for chassis-related components, which need to be particularly precise from the development stage to spot checks at the mass production.
Ultrasonic thickness measurement
Ultrasonic measurement is used to measure panel thickness by directly applying probes to the measurement points. Because it can directly measure the thickness of panels stretched by press machining, even when there are defects such as panel thickness decreasing in prototypes, we can accurately pinpoint them and take countermeasures. Currently, ultrasonic measurement is also frequently used for verification of CAE and CAT simulations, and it has contributed greatly to Hiraoka Body’s accumulation of CAE and CAT technologies and the resulting reduction in lead time.
Welding quality inspection by microscope
Welding is a technology difficult to predict using computers. Hiraoka Body checks weld quality during the development of new products, as well as with regular inspections even after mass production is started, in order to stabilize the quality of our welding and assembly processes. In visual inspections, we observe the fracture surface of the product with a microscope to carefully examine the welding state and effects of the heat. This eye for observation is another facet of our craftsmanship, passed down from one person to the next.
