ISO 9001 certified — quality at every step, not just at the end
We don't just inspect finished products. Quality control starts from the very first step.
Steel hardness testing, material composition verification, supplier qualification review before any processing begins.
Dimensional checks at each machining stage. First-piece inspection for every new batch. Statistical process control (SPC) for critical dimensions.
Rockwell hardness testing after heat treatment. Surface hardness and core hardness verification per specification.
Full dimensional inspection, visual inspection, noise testing (bearings), runout measurement. 100% inspection for critical orders.
Packaging verification, labeling check, documentation review. Final count and condition confirmation before container loading.
Dedicated QC room equipped with professional testing instruments
Micrometers, calipers, bore gauges, height gauges, CMM (Coordinate Measuring Machine) for complex geometries.
Rockwell hardness tester (HRC/HRB), Vickers hardness tester for surface and case depth measurement.
Surface roughness tester, roundness measuring instrument for rotational components.
Bearing vibration/noise tester, torque tester, dynamic balancing equipment for rotating parts.
Operating under internationally recognized quality management and product standards
Quality Management System certification. Our entire operation — from order receipt to shipment — follows documented, audited procedures.
Our products comply with ISO, ANSI/ABMA, DIN, and JIS dimensional and tolerance standards as required by international markets.
Steel grades per GB, SAE, JIS, and DIN standards. Material certificates available upon request for every order.
At IMI, quality isn't a department — it's a culture. Every member of our team, from production workers to management, understands that our reputation depends on the quality of every single component we ship.
