The pultrusion process is a continuous production method of composite material profiles. It is to impregnate the non-twisted glass fiber roving and other continuous reinforcement materials on the creel with resin, and then form by maintaining a certain cross-sectional shape. Mold, and make it solidify in the mold and continuously exit the mold under the pulling force of traction machinery, thus forming an automatic production process of pultrusion products.

PET foam, using PET as the base material to make it have good mechanical properties, so it can be used as the core material of sandwich structure material, and is widely used in construction, road transportation, aviation, shipbuilding, wind power and other fields; Vicell-T The foam also has excellent fatigue resistance and is suitable for various resins and molding processes, and can withstand high curing temperatures during the molding process. Vicell-T foam has a variety of sizes and specifications for customers to choose, and can customize products with different performance requirements and perform various forms of subsequent mechanical processing according to customer requirements.

Balsa has a unique cell structure, light weight and high strength, which make it an ideal material for structural sandwiches. Balsa wood sandwich is a structural sandwich material made of cross-sectional balsa wood. The product undergoes drying, sterilization, splicing, slicing and surface treatment. The density range of balsa sandwich material is between 135-176kg/m³, its strength and rigidity far exceed those of various foams, and the molding temperature is wide (-212°C ~+163°C), which is very ideal Natural sandwich material.
