AI Technical Summary
Traditional cold runner molds are prone to internal stress during injection molding, leading to product quality problems, and their quantity and layout design are difficult to meet the needs of large-scale production.
The multi-stage hot runner injection mold includes a feed channel, a multi-stage gating channel, and a venting system. By combining the main runner, main branch runner, secondary branch runner, and gating channel, the gating space layout is optimized to ensure that the injection material fills the cavity evenly, avoids cooling and solidification, and reduces waste.
It improves material utilization, shortens injection molding cycle, enhances product quality and mechanical properties, and meets the production needs of multi-cavity designs.
