Case Study: Optimizing Costs for Medical Diagnostic Equipment Fasteners
How combining cold heading with secondary CNC finishing saved 30% on production costs for high-precision 316L stainless steel fasteners.
The Challenge: Expensive Materials, High Waste
A medical device company was sourcing precision M2 micro screws in 316L stainless steel via full CNC machining. Due to the material's hardness and the complexity of the shoulder, material waste was over 50%, leading to high unit costs.
The Hybrid Approach
Taily Metal proposed a hybrid manufacturing route: cold heading for the primary blank and head formation, followed by secondary precision CNC grinding for the shoulder. Cold heading reduced material waste to less than 2%.
Quality Control for Clinical Use
Given the medical application, we implemented 100% automated optical inspection (AOI) to check for surface defects and dimensional accuracy, ensuring a zero-defect batch.
Result: 30% Cost Saving
The client achieved a 30% reduction in unit cost while maintaining the exact same precision and material performance required for their diagnostic equipment.
