Manufacturing

Pultrusion is a continuous, efficient manufacturing process for producing fiber-reinforced polymer profiles with stable performance. It pulls continuous fibers through a resin bath, then guides them into a heated die for curing and shaping. The process supports carbon fiber, glass fiber and other reinforcements, creating products with high strength, light weight and corrosion resistance. It enables automated mass production with consistent quality, widely used in construction, automotive, aerospace and infrastructure. With advantages of low waste and high material utilization, pultrusion also matches the development of recycled composite materials, meeting lightweight and eco-friendly industrial demands.

Filament winding is a highly automated composite manufacturing technique. Continuous fibers are precisely wound onto a rotating mandrel under controlled tension, impregnated with resin. After curing and mandrel removal, it forms hollow or solid parts with exceptional strength-to-weight ratio. It is widely used for pressure vessels, pipes, aerospace and automotive components. The process ensures uniform fiber alignment, high structural efficiency and material utilization. Suitable for carbon and glass fibers, it delivers durable, corrosion-resistant products, supporting lightweight and high-performance industrial applications.

Compression molding is mainly divided into prepreg compression molding and liquid compression molding. Prepreg compression molding is the process of cutting the prepreg into a certain size according to requirements, then placing it into a mold, and curing it into shape under certain temperature and pressure. Liquid compression molding is the process of placing a fiber preform into a mold and then injecting resin into the mold cavity to solidify and form it at a specific temperature and pressure. Control point: The resin viscosity and resin rheological property should be proper to match with the technical parameters.
