The pressing plates in a rubber laboratory press are primarily made of SKD chromium-molybdenum alloy, a high-quality material chosen for its durability and resistance to deformation under high loads. These plates undergo multiple surface treatments—high-frequency treatment, carburizing, chromium plating, and polishing—to enhance their hardness (up to 60HRC) and longevity. This ensures precise and consistent performance during material testing, such as rubber or plastic compaction, where maintaining structural integrity is critical. The combination of material strength and surface treatments minimizes wear and deformation, aligning with the rigorous demands of laboratory environments.
Key Points Explained:
-
Material Composition: SKD Chromium-Molybdenum Alloy
- This alloy is selected for its exceptional strength, heat resistance, and ability to withstand high-pressure conditions typical in rubber pressing.
- Chromium and molybdenum improve hardness and corrosion resistance, while the alloy's toughness prevents cracking under repetitive stress.
-
Surface Treatments for Enhanced Performance
- High-Frequency Treatment: Hardens the surface layer to resist wear.
- Carburizing: Infuses carbon into the surface, further increasing hardness and fatigue resistance.
- Chromium Plating: Adds a corrosion-resistant layer, critical for prolonged use with reactive materials like rubber compounds.
- Polishing: Reduces friction and ensures smooth contact with test materials, improving accuracy in thickness measurements.
-
Hardness (60HRC) and Structural Integrity
- The 60HRC hardness rating indicates exceptional resistance to indentation and deformation, ensuring plates remain flat under maximum load.
- This is vital for compliance with legal tolerances for deformation, especially in large-plate presses where even minor warping can skew test results.
-
Role in Laboratory Applications
- These plates are integral to testing rubber, plastics, and laminates, where consistent pressure distribution is needed to analyze material properties like blocking resistance.
- Their durability supports repetitive use in manufacturing R&D, reducing downtime for maintenance or replacement.
-
Integration with Press Systems
- The plates complement other high-quality components (e.g., hydraulic systems, automatic lubrication) to ensure precision and longevity in laboratory presses.
- Their design aligns with pillar-type structures to distribute load evenly, minimizing stress concentrations.
For purchasers, prioritizing these material and treatment specifications ensures reliable performance and cost-efficiency over the equipment’s lifespan. Would the inclusion of temperature-resistant coatings further benefit your specific applications?
