Mold is an important tool for pultrusion technology, generally pre-forming die and molding of two parts. 
 Pre-mold the pultrusion process, the reinforcing material impregnated with resin, (or dipping at the same time), before entering the mold, must be guided by a set of components consisting of yarn preform mold, preform mold is the role of After dipping the reinforcing material, the form in accordance with the configuration profile section, and gradually form a molding control the shape and approximate size of the preform, and then into the forming die, so you can ensure that products containing yarn of uniform cross-section. 
 Mold mold cross-sectional area and cross-sectional area ratio of the product should generally be greater than or equal to 10 to ensure that the mold has sufficient strength and stiffness, after the heat distribution and heat stability. Pultrusion die length of the forming process is based on speed and traction resin gel curing rate decisions, to ensure that products reach when stripping out the degree of cure. Commonly used chrome-plated steel, the cavity surface requires smooth, wear-resistant, pultrusion is to reduce friction and improve mold life.
