Analysis of material selection for medical mold product development

Designers must fully understand relevant factors such as material characteristics, processing technology, environment, standards, etc., master the principles and methods of material selection, and through scientific analysis and thinking, can better select suitable materials for design products.



1. Factors Affecting Material Selection

Functional factors: Functional factors mainly include practical function, aesthetic function and safety performance. Among them, the practical function is the basic function of the product and the leading factor in the selection of materials in the design. ;

Technical factors: technical factors refer to various related technical factors such as material production technology, processing technology, and surface treatment. ;

Economic factors: Economic factors are related to the manufacturing cost and price of products, so designers need to consider competitive products at the same time, so they need to analyze and compare economic factors;

2. Basic principles and methods of material selection

Safety first principle. The product is ultimately used by the user, so the selection of materials must ensure its safety during production and use, and ensure that human health and physical and property safety are protected from injury or loss;

High quality, high efficiency and low cost. In the early stage of product design, material selection must ensure product function and quality on the one hand, and control costs on the other hand;

Meet the function and use environment of product design. The choice of materials to meet the requirements of their functions and use environment is the most important;

Pay attention to the properties of the material. Each material has its particularity, such as nylon is easy to absorb water, pp has poor fluidity, POM has lubricity, but is easy to crack, etc. Only by understanding the particularity of each material can its advantages be maximized, while avoiding Material defects, improve the design quality of the product.

3. Product characteristic requirements and material matching

The design of each product has different requirements, and the functions to be realized and the application environment are different. Now the matching relationship between the special design requirements of the product and the corresponding material type is briefly listed as follows:

The product needs high temperature resistance: choose high temperature material;

Products need good toughness: choose PP, PE, etc.;

Products need high transparency: choose transparent PC;

High product strength requirements: try to choose glass fiber materials;

In short, the selection of materials in product design requires the designer to conduct a comprehensive analysis of various influencing factors, and to carry out the selection of materials throughout the entire design cycle, and select through the above principles and methods. The supplier's technicians discuss, choose to meet the product use requirements and "make the best use of everything", so that the product design can achieve more satisfactory results.
