RUBBER PROCESSING TECHNOLOGY

Molding Processes for Rubber •Principal molding processes for rubber are: (1) compression molding, (2) transfer molding, and (3) injection molding Compression molding is the most important technique because of its use in tire manufacture •Curing (vulcanizing) is accomplished in the mold in all three processes, this representing a departure from

An Introduction to the Optics Manufacturing Process

Oct 31, 2008 · turning, injection molding, and precision glass molding are also discussed. The Beginnings of a Lens The typical life of a lens begins as a glass blank. This is the basic material that the final lens will be made from and can be ordered in many shapes and sizes (Figure 1). These are usually ordered from an optical glass company.
