Mining operations demand tools and components capable of enduring extreme wear, abrasion, corrosion, and high-stress environments. At Neway AeroTech, a premier manufacturer of superalloy cast parts, we specialize in precision-casting custom mining tools designed specifically for rigorous mining applications. Utilizing advanced manufacturing techniques such as vacuum investment casting, we deliver components characterized by exceptional durability, abrasion resistance, and precise dimensional accuracy.
Our deep technical expertise and stringent quality standards make us a trusted manufacturer for custom mining solutions.
Manufacturing superalloy parts for mining presents significant challenges, including:
Wear and Abrasion Resistance: Tools must withstand extreme abrasive conditions without significant wear.
Corrosion Resistance: Components must resist aggressive chemical environments found in mining.
High Mechanical Strength: Required tensile strengths typically exceed 900 MPa to handle intense mechanical stresses.
Precision Tolerances: Maintaining dimensional tolerances within ±0.10 mm and surface finishes as refined as Ra 1.6 µm.
Precise wax patterns replicate intricate geometries required by mining tools.
Ceramic molds formed around wax patterns; wax is removed under precise temperature control (~180°C).
Vacuum casting conducted under pressures below 0.01 Pa to ensure purity and integrity.
Gradual cooling (20–35°C/hour) reduces internal stresses and structural defects.
Equiaxed casting offers uniform grain structures, enhancing overall toughness.
Directional solidification aligns grain structures for improved strength and mechanical performance.
Controlled thermal gradients (20–50°C/cm) minimize grain boundary defects.
