Many electronics manufacturers originally used stainless steel and alloy fixtures. Metal tooling easily deforms, sticks to materials and oxidizes after several high-temperature cycles, dragging down yield. Electronic graphite molds deliver far better stability for mass production. Graphite withstands temperatures up to 1000°C without softening under vacuum or inert atmosphere, an advantage metal cannot match.

Key Properties

Excellent thermal shock resistance: Resists cracking under rapid temperature changes for continuous sintering lines.

Precision machinable: Supports tiny cavities, fine locating pins and narrow slots for microchips and miniature components.

Chemical inertness: No reaction with most electronic pastes and brazing materials.

Lightweight: Easier handling to reduce collision damage during loading and unloading.

Applications

Optoelectronic component packaging, sensor ceramic substrate sintering, lead frame curing, MEMS thermal forming, SPS spark plasma sintering. Jiecheng Graphite selects proper graphite grades based on working atmosphere, peak temperature and cycle quantity to balance cost and service life.
