In today's machining industry, the medical mold industry has become a crucial sector in socio-economic development. The development of many new products heavily relies on advanced mold processing technologies, particularly in automobiles, light industry, electronic components, and aviation.
The advancement of medical mold technology is key to industrial development, involving the intersection of multiple disciplines. As a product with high added value and technology intensity, the technical prowess of molds has become one of the key indicators for assessing the level of "Made in China". Therefore, innovation has rapidly promoted many specialized new mold processing technologies in the manufacturing sector.
New surface treatment technologies for medical mold manufacturing involve systematically altering the shape, chemical composition, and structure of the surface layer of solid metals or non-metal materials to achieve desired surface properties.
Mainly, there are three major categories:
New surface modification technologies for medical molds utilize methods such as plasma technology, lasers, ion beams, and high-density solar energy for ion implantation to achieve surface modification.
New surface coating technologies refer to various metal surface treatment methods to create coatings with special functions on the product surface. Using a small amount of material can produce significant effects that bulk materials may or may not achieve, greatly reducing manufacturing costs. Key features of this technology include wide applicability, with methods such as thermal spraying, electrospark deposition, plastic powder coating, vacuum evaporation, sputtering, ion plating, chemical vapor deposition, molecular beam epitaxy, and ion beam-assisted thin-film technologies.
Composite surface technologies apply two or more surface treatment processes to the same workpiece, not only leveraging the unique characteristics of various surface treatment technologies but also demonstrating outstanding effects when used in combination. Medical molds primarily utilize composite surface treatments such as organic chemical solutions, combined surface heat treatment and organic chemical heat treatment, combined heat treatment and surface deformation strengthening, combined plating and heat treatment, combined coating and surface metallurgization, ion-assisted deposition, laser and ion beam composite vapor deposition, composite coating, and ion implantation and vapor deposition composite surface modification materials.
