Quantified Product Solutions & Core Advantages
|
|---|---|
|
Precision Mold & Tooling Manufacturing PlantsLocal Pain Point: Traditional carbide rotary burr tools have insufficient edge sharpness, causing uneven mold texture engraving, 15%+ surface burr residue, and mandatory manual secondary trimming that delays delivery schedules.
|
Our tungsten carbide burrs with cobalt-alloy sharp edges eliminate secondary trimming. As top-tier best rotary burrs for mold finishing, they reduce surface residue rate to 1.2%, cut manual rework time by 42%, and improve mold surface finish to Ra ≤0.6μm, perfectly meeting European high-precision mold standards.
