Non-Uniform Internal Density of CMC
Fenómeno del problema
Density difference of ±3% in different parts of CMC products
Análisis de la causa
Holding pressure transmission is uneven; areas far from the gate have insufficient holding and low density; regional differences in crystallinity cause different densities
Solución
1)Optimize gate design for uniform holding pressure transmission; 2)Uniform mold temperature to reduce crystallization differences; 3)Multi-point gates to improve holding distribution
Conclusión clave
Non-uniform density is caused by uneven holding; optimizing gate design is the key
