Validated Post-Processing, Chemical Passivation, UDI Laser Marking, and Subassembly Solutions for Global Medical Device OEMs
At Greyack medical Co., Ltd, we understand that precision CNC machining is only part of the manufacturing equation for high-risk medical components. Global medical device OEMs require a fully validated contract manufacturing partner capable of delivering turnkey post-processing, specialized chemical finishing, subassembly, and sterilization-ready packaging.
Our ISO 13485-certified facilities integrate high-tech surface treatment lines, cleanroom mechanical assembly suites, and automated laser marking systems. By managing all secondary processes in-house under strict quality management protocols, Greyack medical Co., Ltd reduces lead times, mitigates supply chain risks, and ensures 100% batch-to-batch traceability for complex orthopedic implants, surgical robotics end effectors, and spinal instruments.
Nitric and citric acid passivation complying with ASTM A967 and ASTM A380 to guarantee optimal corrosion resistance.
Permanent, high-contrast fiber laser etching of UDI 2D matrix codes, lot numbers, and logos resilient to repeated autoclaving.
Multi-stage automated ultrasonic cleaning lines operating under monitored water quality standards to eliminate contaminants.
Precision mechanical integration, torque verification, micro-welding, and functional testing in controlled environments.
Every secondary operation performed by Greyack medical Co., Ltd is tailored to meet the strict regulatory requirements of medical device manufacturing.
Automated chemical lines provide validated citric and nitric acid passivation processes. We maintain strict bath chemistries and temperature controls to remove surface free iron, establishing a passive oxide layer essential for implantable metals and reusable surgical instruments.
Non-destructive fiber laser systems deliver clear, high-resolution marking compliant with FDA Unique Device Identification (UDI) mandates. Marking remains durable across hundreds of sterilization cycles without altering mechanical component tolerances.
Precision hand deburring and controlled abrasive bead blasting create uniform satin finishes, remove microscopic burrs from intricate internal channels, and prepare surfaces for subsequent coating or bonding applications.
State-of-the-art ultrasonic bath sequences utilize RO/DI purified water and specialized biodegradable detergents to clear particulate matter, cutting fluids, and microscopic residue from deep blind holes and cannulated instruments.
Our skilled assembly technicians execute pin pressing, mechanical fastening, micro-welding, and adhesive bonding. Every completed subassembly undergoes 100% tactile, dimensional, and torque testing prior to final acceptance.
We provide custom pouch sealing, labeling, tray kitting, and protective packaging designed for terminal sterilization readiness. Full lot control documents accompany every shipment to streamline your receiving inspection.
How Greyack medical Co., Ltd delivers consistent quality from post-machining to final delivery.
