What is the injection molding process for medical equipment parts?

The medical device parts injection molding process is a complex and delicate process that involves several key steps to ensure the quality and safety of the final product.

Medical equipment parts injection molding process mainly includes the following 6 aspects of detailed steps:

(1) Mold design
This is the basis of the entire process, which needs to be designed in detail according to the specific requirements of medical equipment accessories, such as size, shape and function. In the design process, the fluidity and cooling of the plastic should be fully considered to ensure the practicality and efficiency of the mold.

(2) Material selection
Medical equipment accessories have extremely high material requirements, and it is necessary to select medical plastics with biocompatibility, corrosion resistance, high strength and other characteristics. The choice of these materials directly affects the safety and service life of the product.

(3) Raw material pretreatment
The selected medical plastic raw materials need to be pre-treated such as drying, mixing, and color blending to ensure the quality and stability of the raw materials and prepare for the subsequent injection molding process.

(4) Mold manufacturing
According to the design of the mold drawing, the use of high-strength steel or aluminum alloy mold manufacturing. The manufacturing precision and quality of the mold directly affect the precision and quality of the injection molding product.

(5) Injection molding
The pre-treated medical plastic raw material is heated to melt and then injected into the mold. Under high pressure, plastic is filled into every corner of the mold and cooled to form the required medical equipment parts.

(6) Demoulding and post-processing
Demudding is to remove the product from the mold, and the post-treatment includes removing burrs, painting, assembly and other processes to make the product meet the final use requirements.

Throughout the process, special attention is also required to the maintenance of a dust-free or low-microbial environment, as well as the use of medical-grade plastic materials to ensure that products meet the strict standards and requirements of the medical industry.

In addition, the control and monitoring of the injection molding process is also crucial. This includes precise control of parameters such as temperature, pressure, and speed to ensure product accuracy and consistency.

To sum up, the medical equipment parts injection molding process is a multi-step, high-precision, high-demand process. By strictly following this process, we can ensure the production of high-quality, safe and reliable medical equipment accessories for people’s health.
