To initiate the micro molding process, manufacturers prepare a mold or tooling that contains small cavities shaped according to the desired component. During the liquid injection molding (LIM) process, a liquid silicone rubber (LSR) is rapidly injected into the heated cavity. Here, it undergoes vulcanization and forms the final part.

Micro-milling — also known as fine milling and surface planing — is one of the best ways to restore the age-old, oxidized asphalt pavements. It is considered a better alternative to standard milling, as it produces finer results. While traditional milling leaves the surfaces rough, micro-milling provides a smoother and plainer surface to work with.
