Vacuum infusion process

The vacuum introduction process refers to laying “dry” reinforcement materials (glass fiber, carbon fiber, sandwich materials, etc., different from the vacuum bag process) on the mold, then laying the vacuum bag, and extracting the vacuum in the system to form a A negative pressure uses the pressure generated by the vacuum to press the unsaturated resin/epoxy resin into the fiber layer through the pre-laid pipeline, allowing the resin to infiltrate the reinforcement material and finally fill the entire mold. After the product is cured, remove the vacuum bag material, and The required product is obtained on the mold.
