Molybdenum Machined Plates

 

We machine and supply high-purity molybdenum plates for global mold manufacturers, tooling fabricators, and industrial material distributors. Engineered for extreme service conditions, our plates deliver dimensional stability, resistance to thermal shock, and high wear resistance in plastic mold components and vacuum furnace internals.

 

We process raw materials to your exact CAD drawings and technical specifications, offering both standard thicknesses and fully customized configurations utilizing in-house CNC milling, surface grinding, and wire EDM capabilities.

 

 

High-Temperature Dimensional Stability
Molybdenum retains its mechanical strength and structural integrity under intense thermal loads where conventional tool steels soften or warp.
Melting Point: Approx. 2623°C
Thermal Expansion Coefficient: Approx. 4.8 x 10^-6/K (20–100°C)
High Recrystallization Threshold

• Operational Benefits:
Minimizes thermal deformation during continuous injection molding and heating cycles.
Prevents parting-line mismatch and flash formation in precision plastic components.
Extends component service life in high-stress, heat-intensive zones.
• Primary Applications:
Hot runner manifolds and nozzle inserts
Compression and injection mold inserts
Heat shields and furnace support plates
Precision high-temperature tooling components

 

Tolerances & Complex Machining Capabilities
Because of its high hardness and brittle nature at room temperature, machining molybdenum requires specialized cutting geometry, controlled feed rates, and specialized EDM techniques.
Our facility utilizes dedicated equipment to achieve tight dimensional tolerances and fine surface textures:
• CNC Milling & Turning: For pockets, steps, complex profiles, and counterbores.
• Precision Surface Grinding: For flat parallelism and tight thickness tolerances (+/-0.01 mm or per specification).
• Wire EDM: For intricate internal cutouts, sharp internal corners, and micro-slots.
• Drilling & Tapping: For specialized fastening holes.

Parts arrive ready for immediate assembly into your tooling stack-up without secondary shop-floor processing.

 

Wear Resistance & Mechanical Durability
In continuous industrial production, sliding friction and mechanical loading accelerate wear. Molybdenum's inherent hardness helps resist surface galling and abrasive wear.
Withstands continuous sliding contact and mechanical stress under load.
Reduces unexpected downtime caused by premature tooling failure.
Lowers overall maintenance costs in high-cycle plastic molding operations.

 

Material Purity & Traceability
Component reliability begins with raw material control. We source certified, high-density molybdenum slabs to ensure consistent physical and mechanical properties.
• Minimum Purity: >= 99.95% (Pure Molybdenum / Mo-1)
• Controlled Impurities: Low carbon, oxygen, and nitrogen levels to ensure predictable behavior during high-temperature service.
• Quality Assurance: Full material test reports (MTR) provided with shipments for complete lot traceability.

 

 

 

 

Raw Material Verification: Sourced slabs undergo incoming checks for chemical composition, ultrasonic density testing (upon request), and dimensional verification.

 

Machining Setup: Stock is secured using low-stress clamping fixtures. Feed rates, speeds, and coolant strategies are optimized specifically for refractory metals to prevent micro-cracking.

 

Surface Finishing: Parts undergo precision grinding or chemical cleaning to remove machining marks and achieve target surface roughness values (Ra).

 

Final Dimensional Inspection: Every machined plate is measured using calibrated micrometers, height gauges, and optical comparators to verify thickness, flatness, and geometric tolerances against customer drawings.

 

 

Plastic Injection Molding
Precision mold inserts, hot runner backup plates, and wear plates exposed to aggressive engineering plastics and thermal cycling.

 

Vacuum & Thermal Processing Furnaces
Radiation shields, heating elements support structures, hearth plates, and boat fixtures operating in inert or vacuum atmospheres.
