Drawing design for medical injection molds is a core aspect of the mold production process and an indispensable basis for mold manufacturing. A detailed and accurate mold drawing is key to ensuring mold quality and production efficiency. So, what are the key elements involved in the drawing design of medical injection molds?

Firstly, designers need to have a deep understanding of the plastic products to be produced. This includes grasping the structural characteristics and uses of the products, as well as the different requirements for product shape, dimensional tolerances, and surface quality based on different uses. At the same time, the molding characteristics of the plastic materials, such as shrinkage rate, flow characteristics, and the temperature conditions required for injection molding, also need to be considered, as these are important factors that affect mold design.

Secondly, the production volume of the products is also an aspect that cannot be ignored in mold design. Based on the demand quantity of the products, designers need to determine the service life of the mold, the number of mold cavities (or the number of mold sets), as well as the degree of automation and production cost of the mold. For products with large demand, priority should be given to adopting multi-cavity molds, hot runner molds, and mold structures suitable for fully automated production. For products with smaller demand, mold costs should be minimized while meeting quality requirements.

Finally, designers also need to understand the injection molding equipment used to produce the plastic products. Medical injection molds need to be installed on injection molding machines for use, so factors such as the mold installation dimensions, ejection position, injection pressure, clamping force, and injection volume of the injection molding machine will all affect the size and structure of the mold. These factors need to be fully considered during design to ensure a perfect match between the mold and the injection molding machine.
