When it comes to moulding, achieving the desired quality, functionality, and visual appeal of the final product turning point on surface texture. Surface texture encompasses the tactile and visual characteristics that define a surface, such as its smoothness, roughness, and appearance. It is a result of various factors, including the moulding process, tooling techniques, and material selection. Understanding types of surface textures is paramount in the designing stage based on the functionality of the product being designed.

Surface texture plays an important role in injection moulding for both functional and aesthetic aspects of the final product. Functionally, the surface texture impacts crucial factors such as friction, wear resistance, and part release. It can enhance the performance of moving components by reducing frictional forces, preventing sticking or binding. Additionally, the texture can influence the appearance and perceived quality of the product, making it visually appealing and pleasing to touch. Whether it's achieving a glossy, matte, or textured finish, the right surface texture selection can significantly enhance the marketability, customer satisfaction, and overall success of products.

The VDI 3400 and SPI Finish are the two most widely used surface finishes for molds. They consist of 90% of finish references on the market.
