The design and manufacture of medical mold injection molding are intimately tied to the nuances of plastic processing. The success of plastic processing largely hinges on the effectiveness of mold design and the quality of mold manufacturing, both of which are founded on accurate plastic product design, particularly in the medical field.

When delving into the intricacies of medical mold injection molding design, the following structural elements shine like stars, guiding us through its essence:

1. Parting Line Artistry: The parting line, where the cavity and core meet during mold closure, is meticulously chosen based on product shape, appearance, wall thickness, molding method, post-processing, mold type and structure, demolding technique, and molding machine configuration.

2. Structural Component Wisdom: Complex mold features such as sliders, angle pins, and straight ejector pins are pivotal. Their design impacts mold lifespan, processing cycle, cost, and product quality. Designing these core structures demands high comprehensive ability, striving for simplicity, durability, and economy.

3. The Path to Precision: Medical mold injection precision encompasses elements like part avoidance, precise positioning, guide posts, and locating pins. This precision system safeguards product appearance, mold quality, and longevity. Tailored positioning methods and meticulous machining ensure adjustable, well-designed internal mold positioning.

4. The Science and Art of Gating Systems: The gating system, from the injection molding machine's nozzle to the cavity, includes the main runner, sub-runners, gates, and cold slug wells. Gate placement is crucial for optimal plastic flow, ensuring easy removal of solidified runners and gate cold slugs upon mold opening (except for hot runner molds).

5. Balancing Shrinkage and Dimensional Accuracy: Medical mold injection design also considers shrinkage and factors affecting product dimensional accuracy, such as mold manufacturing and assembly errors, and mold wear. Additionally, designing compression and injection molds necessitates precise matching with molding machine process and structural parameters. Computer-aided design technology is widely applied in medical mold injection design.
