What are the requirements for the injection molding of medical products?

Accuracy and dimensional stability

Medical products place extremely high demands on dimensional accuracy and stability. In the process of injection molding, the mold temperature, injection pressure, injection speed and other parameters must be strictly controlled to ensure the dimensional accuracy of the product. At the same time, the shrinkage of the material needs to be taken into account, and the mold needs to be precisely designed to compensate for the shrinkage of the material during the cooling process. In addition, by optimizing process parameters and mold design, the dimensional stability of the product can be improved and dimensional changes caused by environmental factors such as temperature and humidity can be reduced.

Surface

The surface quality of a medical product has a direct impact on its longevity and patient experience. During the injection molding process, it should be ensured that the surface of the product is smooth and clean, free of scratches, bubbles and other defects. This requires strict control of parameters such as the cleanliness of raw materials, the maintenance and lubrication of molds, and the injection pressure during processing. In addition, the surface quality of the product can be further improved by employing high-precision molds and advanced processing technology.

Sterility & Cleanliness

Medical products must be kept sterile during use. Therefore, in the process of injection molding, the cleanliness of the production environment must be strictly controlled to avoid pollution. At the same time, raw materials, semi-finished products and finished products are strictly cleaned and disinfected to ensure that the products meet the requirements of sterility. In addition, production equipment and tools should be regularly maintained and cleaned to prevent the growth of contaminants.

Traceability & Quality Control

Medical products have extremely strict quality requirements, and traceability and quality control systems must be established. In the injection molding process, each production link should be strictly monitored and recorded to ensure that the product quality can be traced. At the same time, establish a strict quality inspection system to conduct quality inspection of semi-finished products and finished products to ensure that products meet relevant standards and requirements. In addition, production equipment should be regularly maintained and calibrated to ensure machining accuracy and stability.
