The company sources premium raw materials, such as high-strength aluminum alloys for cylinder heads and ductile iron for crankshafts, to ensure durability under high-stress conditions. Each part undergoes multi-stage quality control, including visual inspections, dimensional measurements using coordinate measuring machines (CMM), and non-destructive testing. The company complies with international standards like ISO 9001, implementing statistical process control to monitor production variability. Additionally, parts are tested for thermal stability, wear resistance, and operational efficiency in simulated engine environments. The result is a range of Isuzu parts that match or exceed original equipment quality, providing reliable performance and extended service life for vehicles and machinery.
