VINACNC - Expert Manufacturer of High-Precision Graphite Sintering Molds for Glass

In the glass manufacturing industry, using a high-quality sintering mold is a key factor in creating glass products with precise shapes and dimensions. VINACNC is proud to offer a specialized graphite sintering mold manufacturing service, designed to meet the most stringent requirements of the glass sintering process.

Technical Specifications, Materials, and Applications

• Material: The products are crafted from high-purity graphite. This material stands out for its exceptional heat resistance, chemical corrosion resistance, and non-reactive nature with molten glass, which helps maintain the integrity of the product during the sintering process.

• Technical Properties:

  • Heat Resistance: Graphite can withstand temperatures of over 3000°C, making it ideal for sintering glass at high temperatures (typically around 1400°C).

  • Tight Tolerances: The molds are CNC machined to achieve precise tolerances, ensuring the final glass product has a perfect shape and size.

  • Smooth Surface: Graphite molds have a naturally smooth surface, which allows the sintered glass to easily separate from the mold after cooling, and also results in a fine surface finish on the final product.

• Applications: Graphite sintering molds are used for:

  • Artistic Glass Sintering: Creating glass products with complex shapes, decorative items, or special components.

  • Optical Lens Production: Shaping lenses, prisms, and other optical components.

  • Industrial Glass Parts: Manufacturing glass parts for laboratory use, lighting equipment, or other industrial devices.

Product Advantages

• High Precision: Thanks to CNC machining, the sintering molds have absolute dimensional accuracy, creating uniform and standard-compliant glass products.

• Heat and Corrosion Resistance: The extremely high heat and corrosion resistance of graphite ensures a long mold lifespan and allows for multiple reuses.

• Chemical Inertness: Graphite is an inert material that does not react with molten glass, ensuring the quality and transparency of the final product.

• Optimized Costs: The long mold lifespan and high production efficiency help minimize investment and operational costs for our clients.

Post-Machining Product Inspection Process

1. Dimensional Inspection: We use digital calipers and other precision measuring tools to verify the dimensions of the graphite mold against the technical drawings.

2. Surface Finish Inspection: We conduct visual inspections and use specialized measuring devices to ensure the mold surface meets the requirements and is free of cracks or defects.

3. Functional Test: A trial sintering run is performed with glass to evaluate the quality of the resulting product and the mold's release properties.

Packaging and Storage Process

• Cleaning: The mold is thoroughly cleaned to remove carbon dust and other impurities.

• Careful Packaging: The product is packed in a sturdy cardboard box or a wooden crate with foam to prevent impact and chipping during transport.

• Labeling and Instructions: The packaging is clearly labeled with product information, including the product code, dimensions, and usage/storage instructions.

• Storage: We recommend storing the mold in a dry, cool environment, away from heavy impacts, to maintain its best quality.
