Platinum Plate/Sheet/Disc Manufacturing Processes

• Raw Material Purification: High-purity platinum (typically ≥99.95%) is refined via electrolysis or chemical methods to remove impurities.
• Melting & Casting: The platinum is melted at high temperatures in an inert gas atmosphere and cast into billets.
• Rolling: The ingots are hot-rolled into thinner plates or sheets using heavy rolling mills. This process is repeated with decreasing roller gaps to achieve the desired thickness. Cold rolling may follow for finer tolerances and smoother surfaces.
• Annealing: The rolled sheets are annealed (heated and slowly cooled) to relieve internal stresses and improve ductility, ensuring the material is workable without cracking.
• Cutting: The desired sizes are available using precision tools like laser or waterjet cutters.
• Precision Finishing & Surface Treatment: Polishing and ultrasonic cleaning are applied to ensure a flawless surface, critical for high-purity applications (e.g., semiconductors or medical devices).
• Quality Inspection: Spectrometry (composition check), dimensional measurement (micrometer/laser gauging), leak testing, and microstructure analysis (metallography) are conducted to verify compliance.

Platinum Plate/Sheet/Disc Applications

• Catalysis: They can be used in catalytic converters to accelerate chemical reactions, particularly in automotive exhaust systems.
• Electronics: They serve as contacts or electrodes in high-performance electronic devices, such as thermocouples and sensors.
• Chemical Processing: They are used as catalyst supports or in the production of various chemicals due to their inertness and stability under harsh conditions.
• Medical Devices: They are used in medical devices, including pacemakers and other implants, because of their biocompatibility and resistance to corrosion in the human body.
• Laboratory Applications: Used in laboratory equipment like crucibles and reaction vessels where high temperatures are involved.

Platinum Plate/Sheet/Disc Packaging

Platinum Plate/Sheet/Disc is carefully placed in wooden cases or cartons with additional soft materials to support and prevent shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
