· Product Overview

· Core Specifications

• Material: 99.5% High-Purity Alumina CeramicOffers extreme temperature resistance (up to 1600°C), high hardness (HRA 88–90), and chemical inertness (resists most acids/bases except strong alkalis).
• Manufacturing Standard: ISO 9001-Certified Precision Ceramic Processing
  • Key Processes: Alumina powder mixing → isostatic pressing (tapered cup blank shaping) → high-temperature sintering (1600°C densification) → precision machining (internal slot + top indent) → surface finishing.
  • Key Parameters:
    • Standard Dimensions: Top diameter ~50mm, height ~40mm (fully customizable)
    • Dimensional Tolerance: ±0.1mm (ensures consistent mating/holding)
    • Surface Finish: Sintered smooth (non-porous, easy to clean)
  • Performance Rating: Thermal shock resistance (ΔT ≥ 200°C); non-magnetic, non-conductive.

· Application Scenarios

• Laboratory Thermal Processing: Holding samples in high-temperature muffle furnaces, ceramic material sintering tests, or heat-treatment experiments.
• Industrial Sintering Jigs: Fixtures for electronic component (e.g., ceramic capacitors) sintering, or metal powder heat-processing holders.
• Chemical-Resistant Containers: Holding corrosive samples (acids/bases) for lab analysis, or small-batch chemical reaction vessels.
• High-Temp Equipment Components: Internal holders for industrial furnace parts, or thermal insulation component fixtures.

· Production Process Introduction

1. Alumina Powder Preparation: Mix 99.5% purity alumina powder with binders to form a moldable paste.
2. Isostatic Pressing: Shape tapered cup blanks via isostatic pressing (uniform pressure ensures consistent density).
3. Drying: Remove moisture from blanks to prevent cracking during sintering.
4. High-Temperature Sintering: Heat blanks to 1600°C in a controlled atmosphere furnace to densify the ceramic and achieve target hardness.
5. Precision Machining: Add the internal slot (for holding) and top indent (for mating) via diamond-tipped machining tools (ceramic-specific equipment).
6. Quality Inspection: Verify dimensional accuracy (calipers/CMM), density (Archimedes method), and surface integrity (visual + porosity checks).
7. Sorting: Group cups by specification for inventory.

· Packaging and Shipping Methods

• Packaging: Each cup is individually wrapped in shock-absorbent foam; bulk orders are packed in rigid, foam-lined cardboard boxes (critical for preventing ceramic breakage during transit).
• Shipping: Flexible logistics options:
  • Express Delivery (DHL/FedEx/UPS: 3–5 business days)
  • Air Freight (7–10 business days)
  • Sea Freight (20–30 business days)All shipments include full tracking and breakage insurance.

· Frequently Asked Questions (FAQ)

• MOQ (Minimum Order Quantity): 300 pieces per standard specification; small sample packs (10–20 pieces) are available for performance testing (additional handling fees apply).
• Lead Time: Standard lead time is 10–15 working days (sintering is a time-intensive process); expedited production (8–10 working days) is available for urgent orders (premium fees apply).
• Customization Capability: Full customization is supported—we can adjust cup dimensions (diameter/height), modify slot/indent design, or upgrade to 99.9% high-purity alumina (for ultra-high-temp use) based on your technical drawings. Our ceramic engineering team will validate design feasibility for sintering and performance.
