Mining operations demand extremely durable tools capable of withstanding harsh conditions such as severe abrasion, corrosion, and intense mechanical stresses. Neway AeroTech, a specialized superalloy casting factory, delivers precision-engineered components designed specifically for rigorous mining applications. Utilizing advanced methods like vacuum investment casting, we produce highly reliable, corrosion-resistant, and wear-resistant mining tools with exceptional precision.
Our comprehensive expertise positions us as a trusted partner in custom superalloy parts casting.
Core manufacturing challenges include:
Wear Resistance: High abrasive environments demand components with superior wear resistance.
Corrosion Resistance: Components must endure aggressive chemical exposures common in mining environments.
High Mechanical Strength: Parts require tensile strengths over 900 MPa to withstand significant mechanical stresses.
Precision Requirements: Maintaining strict dimensional accuracy within ±0.10 mm and surface finishes as fine as Ra 1.6 µm.
Intricate wax patterns precisely replicate component geometries.
Ceramic molds are formed around wax models, and the wax is removed at controlled temperatures (~180°C).
Casting under vacuum (<0.01 Pa) ensures material purity and structural integrity.
Gradual cooling rates (20–35°C/hour) minimize internal stresses and structural defects.
Equiaxed casting delivers uniform grain structures, increasing component toughness.
Directional solidification aligns grains, significantly enhancing mechanical strength and creep resistance.
Controlled thermal gradients (20–50°C/cm) ensure grain alignment and reduce defects.
