GBT528 Rubber Tensile Test Knife Mold – Manganese Steel

Precision Rubber Sampling, Every Cut. Every Time.

In materials testing, imprecise sampling means unreliable results — and unreliable results mean wasted time, wasted materials, and compromised research. The GBT528 Standard Knife Mold is engineered to eliminate that problem, delivering clean, consistent dumbbell-shaped specimens with every single cut. Whether you’re running tensile strength tests in a university lab or a professional materials testing facility, this is the tool that gets it right.

Manufactured to the GBT528 standard and constructed from high-grade manganese steel, this dumbbell-shaped cutting knife mold is purpose-built for rubber tensile test specimen preparation. The precision-machined cutting edge produces clean, burr-free samples that conform to standardized test dimensions, ensuring your tensile testing data is accurate and reproducible. Available in Type 1A and Type 2 dumbbell configurations, it covers the most common GBT528 specimen geometries in a single, easy-to-handle tool that professionals and researchers rely on daily.

Key Benefits

• GBT528 Standard Compliance — Designed specifically to meet GBT528 rubber tensile testing standards for accurate, reproducible specimen preparation.
• Manganese Steel Construction — High-grade manganese steel delivers exceptional hardness and edge retention for long-lasting, consistent cutting performance.
• Dumbbell-Shaped Cutting Profile — Precision-machined geometry produces clean, standardized specimens with every cut, eliminating manual trimming and measurement error.
• Type 1A & Type 2 Configurations — Covers the two most common GBT528 dumbbell specimen types, giving labs maximum versatility from a single tool.
• Ergonomic & Easy to Operate — Designed for comfortable, controlled use in laboratory environments, reducing operator fatigue during high-volume sampling sessions.
• Compact & Lab-Ready — Small footprint (1.2 × 0.8 × 0.4 inches packaged) makes it easy to store and deploy in any lab or field testing setup.

* This tool is intended for professional laboratory and materials testing use. Always follow applicable safety protocols when operating cutting tools. Specimen dimensions should be verified against your specific GBT528 test standard revision before use. Not suitable for cutting materials other than rubber or elastomers.
