模具制造材料

As a product developer, you only need to have a basic understanding of mold making materials.

Types and Applications

Brief understanding of mold making materials

For our customers, a basic understanding of mold-making materials can also provide a small help for their own products.

This knowledge facilitates clearer communication and more accurate specifications, enabling our customers to make informed decisions about materials based on their product’s performance, cost, and quality. It helps our customers set realistic expectations for product performance and limitations, understand the general costs of product manufacturing, and plan for potential supply chain issues.
