Injection molding is a technique that combines various molds and injection molding machines to produce plastic products. This process, primarily involving rubber and plastic materials, encompasses four core stages: filling, pressure holding, cooling, and demolding, which directly influence the quality of the molded product. So, what key points should we pay attention to in the injection molding of medical plastics?

1. Precise Temperature Control: Different raw materials require different temperatures during injection molding. Too high or too low temperatures can adversely affect the processing of the material and the final product quality. For example, low temperatures may cause color abnormalities in liquid materials, while high temperatures can result in product defects such as burrs.

2. Appropriate Cooling Time: The cooling time in injection molding cannot be overlooked, and its duration should be flexibly adjusted according to the specific characteristics of the product. Proper control of cooling time is crucial for the surface gloss of the product, which directly affects its appearance quality.

3. Careful Injection Speed Regulation: During injection molding, the injection speed within the sprue also needs to be carefully controlled. Excessive speed may lead to issues such as burrs, overfilling, and burning, while insufficient speed can cause shrinkage and easy fracture. Therefore, strict monitoring and adjustment of the injection speed are necessary to ensure that the produced medical plastic products meet quality requirements.

In summary, precise temperature control, appropriate cooling time, and careful injection speed regulation are crucial in the injection molding of medical plastics. Following these key points will help improve product quality and meet the stringent standards of the medical industry.
