Description
High Purity Custom Graphite Trays for Vacuum & Sintering Furnaces
SHJ CARBON supplies high purity, high-density graphite plates engineered for vacuum furnaces, sintering lines, MIM processing, and high-temperature thermal treatment.
Our graphite plates are designed to maintain mechanical stability, thermal uniformity, and low contamination during repeated heating cycles.
We machine graphite plates according to customer dimensions, load requirements, and furnace configuration, ensuring long-term reliability under demanding thermal environments.We support customers in defining the most efficient graphite plate or tray layout by evaluating:
- Furnace chamber size and thermal field distribution
- Component shape, weight, and packing density
- Required output and batch processing parameters
Engineered for High-Temperature Stability and Dimensional Precision
Graphite plates serve as structural and support components inside industrial furnaces, where process atmospheres require low impurity and minimal distortion.
Key performance advantages include:
- Thermal stability up to 3000°C in inert/vacuum atmospheres
- Isotropic structure, providing consistent strength in all directions
- Low thermal expansion, preventing warping during repeated cycling
- High purity and reduced contamination for critical materials
- Stable mechanical support for batch loading and component fixtures
These properties make graphite plates suitable for precision sintering and controlled heat treatment workflows.

Pair Graphite Plates with CFC Baskets to Improve Cycles and Load Stability
In addition to custom graphite trays, SHJ CARBON also manufactures CFC (Carbon Fiber Composite) fixtures for high-temperature furnace systems. CFC components are engineered to deliver high strength, low weight, and excellent thermal shock resistance, making them particularly suitable for continuous and batch heat treatment environments.
CFC fixtures are recommended for heat treatment operations where cycle repeatability, reduced mass, energy efficiency, and long-term durability are critical requirements. SHJ CARBON provides engineering support to analyze furnace conditions, part geometry, and workload patterns to determine when CFC is the optimal complement to graphite fixtures.
If you are considering upgrading your current workload support system to improve throughput stability or reduce maintenance frequency, we can provide a comparative evaluation and configuration proposal based on your furnace application.
