BMC Injection Molding Pressure Control Points
Author： Published：2026-06-25 Clicks：
BMC Injection Molding Pressure Control
Pressure control is critical in BMC (Bulk Molding Compound) injection molding. Key points: 1) Injection pressure is typically higher than thermoplastics (100-200 bar), 2) Holding pressure must be maintained during curing to prevent sink marks, 3) Back pressure affects material homogenization, 4) Pressure profiles should be optimized for part geometry. Proper pressure control ensures complete filling and consistent part density.
