Inspection System Guaranteeing Quality
We recognize that customer expectations will inevitably continue to rise.
Therefore, we actively pursue both the enhancement of inspection techniques and investment in equipment.
Here, we introduce our inspection system that guarantees high strength and high quality.
We measure the composition of molten metal dissolved in the high-frequency furnace using a CE meter and vacuum-type kant recorder at the furnace front, managing composition control.
We cast test pieces daily and machine them into various test specimens using an NC lathe for specimen cutting. We verify tensile strength and other properties using an Amsler-type tensile testing machine, ensuring material quality.
For new product launches, dimensions are measured using a coordinate measuring machine, enabling three-dimensional inspection from all directions.
We maintain three 3D scanners for specific applications, utilizing them for product dimensional inspection, mold wear management, and customer measurement requests.
Products are sampled, and their actual microstructure is examined under a microscope to confirm spheroidization rate, pearlite rate, and the presence or absence of chill.
Using a metallographic microscope and image analysis software, we measure spheroidization rate and P/F ratio. Depending on customer requirements, measurements can be performed using either the NIK method or the ISO method.
We measure the hardness of various test specimens and actual products using Brinell hardness testers (hydraulic/lever type), Vickers hardness testers, and Rockwell hardness testers to guarantee material quality.
All products shipped are individually inspected by specialized technicians before delivery to customers.
