Blade Selection Criteria for Different Materials

By Material Thickness

Material thickness directly determines optimal blade specifications. For ultra-thin materials <20μm (battery foils, thin-film sensors), select Shengao's 0.15-0.20mm thick blades with 16° cutting angles. Standard electronic films 20-100μm (FPCBs, flexible displays) perform best with 0.20-0.30mm blades at 14° angles. Thicker materials 100-500μm (composite films, rigid-flex PCBs) require 0.30-0.50mm blades with 12° cutting angles. Our application engineers can provide precise recommendations based on your specific material stack composition and layer structure.

By Coating Type

Coating selection significantly impacts blade performance and lifespan. Choose TiN coating for general-purpose processing of multiple materials with moderate abrasiveness. Select TiCN for battery electrode applications where metal transfer prevention is critical. Specify AlTiN when processing highly abrasive materials like ceramic-filled substrates or ITO coatings. For semiconductor applications requiring maximum purity and hardness, DLC coating provides superior performance. Our CrN coating offers the best solution for adhesive-intensive applications like FPCB lamination where material buildup causes production issues.

Run new blades at 50% normal speed for the first 500 meters to establish proper edge geometry before full-speed operation. Shengao provides detailed installation manuals and video tutorials for all blade types.

Cleaning & Decontamination Protocols

Regular cleaning extends blade life and maintains cutting quality. For most electronic materials, clean blades every 8 hours of operation using semiconductor-grade isopropyl alcohol and lint-free wipes. Remove adhesive buildup immediately using specialized solvent solutions matched to your specific material. Ultrasonic cleaning with deionized water is recommended for blades used in semiconductor applications. Always store blades in protective cases with desiccant packs to prevent corrosion. Shengao offers professional reconditioning services that restore blades to like-new condition at 40-60% of new blade cost.

Blade Lifespan Extension Strategies

Implementing proper maintenance protocols can extend blade lifespan by 30-50%. Rotate blades periodically to distribute wear evenly across the cutting edge. Document blade performance metrics to establish predictive replacement schedules before quality degrades. Maintain optimal environmental conditions (40-60% RH) to prevent corrosion during storage. Use blade edge inspection microscopes to detect micro-chipping early before it affects cutting quality.
