SPI Surface Finish Guidelines

When adhering to SPI Surface Finish Guidelines for plastic molding, you can achieve specific standards ranging from A-1 to B-2, guaranteeing the desired level of surface smoothness and glossiness in molded parts.

These guidelines cater to a wide range of aesthetic requirements and functional needs in the production of high-quality molded parts. For instance, an A-1 finish with a surface roughness (Ra) of 0.012 to 0.025 is ideal for clear parts where a super high glossy appearance is essential.

On the other hand, finishes like A-2 to B-2 are tailored to meet various aesthetic and functional demands across different industries. SPI grades such as A-1 and A-2 offer smooth surfaces with low roughness, which not only enhance the visual appeal of the parts but also contribute to their functionality.

Additionally, different SPI finishes like A-3 for general-purpose parts and B-1 for functional components provide a spectrum of surface roughness options to meet diverse application needs effectively.

Adhering to SPI Surface Finish Guidelines guarantees that your plastic molded parts meet the required standards for both form and function.

VDI 3400 Surface Finish Standard
