Key Material Properties & Industrial Application
High-Temperature Structural Integrity
Molybdenum maintains its mechanical strength and creep resistance at elevated temperatures where conventional steels and nickel-base superalloys fail.
• Plastic Mold Industry: Used for precision mold inserts, heat-resistant partition plates, and hot-runner components, preventing thermal fatigue and distortion during high-cycle injection molding.
• Thermal Processing: Utilized for vacuum furnace heating elements, heat shields, and sintering boats exposed to cyclic heating up to 1,800 deg C in protective atmospheres.
Low Thermal Expansion & High Precision
With a low coefficient of thermal expansion (4.8 x 10^-6 / K), molybdenum components experience minimal dimensional change during rapid thermal fluctuations. This ensures tight tolerances are maintained in semiconductor processing fixtures and precision aerospace tooling.
Surface Finish Options
As-Rolled Surface: Retains the mill finish; optimized for general industrial structures or customers performing secondary blanking and machining.
Alkaline Cleaned / Chemically Etched: Oxide-free surface finish suitable for vacuum furnace environments where outgassing must be minimized.
Ground / Polished Surface: Mechanically ground to achieve a surface roughness of Ra <= 0.8 um, ensuring precise thickness uniformity and flatness for mold contact surfaces.
Processing & Custom Fabrication
We deliver semi-finished plates or fully finished components based on CAD drawings, backed by years of manufacturing experience serving global vacuum furnace and mold industry leaders. Our internal secondary processing capabilities include:
Laser & Waterjet Cutting: For net-shape or near-net-shape blanks.
CNC Milling & Drilling: For complex pocketing, counterbores, and cooling/ventilation hole patterns.
Surface Grinding: To achieve tight thickness tolerances (+- 0.02 mm available upon request).
Quality Assurance & Material Traceability
Every production lot undergoes rigorous inspection prior to dispatch:
Chemical Analysis: Spectrographic verification ensuring Mo >= 99.95% and controlled interstitial impurity levels (C, O, N, H, Fe, Si).
Dimensional Verification: Micrometer and coordinate measuring machine (CMM) checks for thickness, width, length, and flatness deviation.
Material Certification: Supplied with a Mill Test Certificate (MTC) in accordance with EN 10204 / 3.1.
