Shear Blades
Precision Shear Blades for Container & Specialty Glass
Engineered for exacting separation of glass gobs—across food & beverage, tableware, crystal, and specialty glass production.
Blades Built to Perform—Gob After Gob
Dura Temp offers shear blades that are purpose-built to handle the intense thermal, mechanical, and precision demands of the glass forming process. Whether you’re producing high-volume containers or premium tableware, our blades ensure clean cuts, extended wear life, and consistent drop behavior.
From single-gob all the way to quadruple-gob production, our blade families are optimized for uniform wear, high-pressure performance, and seamless compatibility with your feeder systems. Every blade is finished to exacting tolerances—ground, bead-blasted, and etched for traceability—and undergoes stringent quality control backed by real-world production experience.
Why Our Shear Blades Are Different
🔧 Optimized Geometry
Our shear blade cutting profile for your specific gob diameter and feeder setup—available in straight, 30°, 45°, or compound angle cuts (30°/60°).
🧊 Surface Finish That Works Harder
A bead-blasted matte finish enhances coolant retention and thermal balance—keeping blade edges cooler and extending service life.
💪 Durability
Special alloy composition and thermal processing convert surface microstructure into hardwearing carbides—protecting against overload and impurities.
📐 Precision Parallelism
Tight planarity tolerances ensure balanced cutting force across gob pairs, preventing blade chatter and reducing wear on feeder mechanisms.
🌀 Custom Configurations
From SM-style block blades to radius blades (10–55 mm), we can supply shear blades to your specs—whether for standard IS machines or specialized press/crystal lines.
♻️ Regrind and Resharpen
Some Blades are designed for multiple regrind cycles without sacrificing performance. Reconditioning blades to match OEM quality can save you money.
