Zirconia Ceramic Sintering Furnace for Ferrules, Sleeves and Precision Components
PRODUCT PARAMETERS
Description
Used for sintering zirconia ferrules, sleeves, and other ceramic components
The V-type high-tech ceramic kiln furniture is specifically designed for the high-temperature sintering process of precision tubular ceramic products such as zirconia ferrules and sleeves. This series of products is made of high-purity, high-temperature resistant ceramic materials, ensuring no contamination of the fired products during sintering and guaranteeing the purity and material properties of the ceramic products.
Its core innovation lies in the corrugated V-groove structure. This design, by minimizing the contact area, greatly reduces external force interference during the high-temperature shrinkage process of the ceramic products, effectively avoiding defects such as deformation and adhesion. Simultaneously, the V-groove surface possesses excellent smoothness and extremely high dimensional accuracy, ensuring not only a smooth appearance after sintering but also strict control over the roundness, straightness, and consistency of the outer diameter, making it an ideal choice for improving the yield and reliability of high-end ceramic components.
Product Features
- Pollution-Free Sintering, Ensuring High Material Purity
Using high-quality, high-tech ceramics as the kiln furniture base, it does not chemically react with the fired products under high-temperature conditions, resulting in no slag or volatilization. This ensures the purity and stable performance of zirconia, alumina, and other ceramic products after sintering.
- V-Shaped Corrugated Micro-Contact Design, Minimizing Sintering Interference
The unique corrugated V-shaped support structure ensures that the product and kiln furniture are in “line contact” or “point contact.” During the high-temperature sintering shrinkage stage, this design greatly reduces the frictional resistance and constraint stress generated at the contact surface, effectively preventing core and sleeve deformation and improving roundness.
- High-Gloss V-Groove, Guaranteeing Appearance and Dimensional Accuracy
The precision-machined V-groove inner wall has an extremely high degree of smoothness, resulting in a burr-free and pit-free product surface after sintering. Simultaneously, the opening angle and depth tolerances of the V-groove are extremely strict, ensuring consistent positioning of each product at the sintering station, thereby guaranteeing a high degree of uniformity in the outer diameter dimensions of batch products.
- Flexible customization to suit various tubular products
The company has a mature mold processing system. In addition to providing V-groove plates of various standard specifications, it can also customize special V-groove plates according to the product diameter, length and production capacity requirements provided by customers to meet the sintering needs of different pipe diameters and irregularly shaped pipes.

Frequently Asked Questions (FAQ)
- Will the V-groove plates deform after long-term high-temperature use, thus affecting product accuracy?
Our V-groove furniture uses a special refractory ceramic formula with high thermal shock resistance and a high load softening point, and undergoes high-temperature pre-firing treatment. Under repeated use within the normal operating temperature range (such as the core sintering temperature), its V-groove exhibits excellent dimensional stability and can maintain positioning accuracy over a long period.
- When using this furniture, is it necessary to apply additional isolation powder inside the V-groove?
Generally, no. Because the V-groove surface has a high gloss and the material itself does not react with zirconium oxide or alumina, normal loading is sufficient. It is recommended to clean residual dust inside the groove regularly according to actual working conditions to maintain optimal contact.
- How do I determine whether I should choose the standard specification or a customized specification?
If your product diameter matches the standard groove width, you can directly choose the standard product to shorten the delivery time. If your product has a special diameter or specific requirements for the number of sintering cycles per batch (e.g., multi-layer stacking), we suggest you provide product drawings or samples. We will design a customized V-groove plate with the optimal layout for you.
- What is the maximum operating temperature of this kiln furniture?
Our standard V-type high-tech ceramic kiln furniture can be used stably for extended periods below 1650℃, fully covering the sintering temperature range of zirconia (approximately 1450-1550℃) and alumina (approximately 1600℃) ceramics. For higher temperature requirements, custom-made furniture made from specific materials is available.
