The manufacture of glass fiber starts with the mixing of batch ingredients in precise proportions.

The manufacture of glass fiber starts with the mixing of batch ingredients in precise proportions. This mixture is then melted in a high temperature furnace. While in a molten state, the viscous glass is drawn through plantinum bushings in continuous filament form by high-speed precision winders. A chemical treat-ment usually referred to as sizing is applied to the filaments during the winding process to coat the filaments during subsequent processing steps. The glass fiber has a low alkali content.
