Pultrusion die

Wear-resistant and high-temperature resistant, the polished cavity of the pultrusion die ensures smooth demolding and supports continuous pultrusion of multi-cross-section profiles. The finished products feature a clean appearance, reduce post-processing grinding work, and help improve production efficiency while reducing costs.

Optimized Pultrusion die Design for Stable and Continuous Profile Production

Each Pultrusion die is custom-designed according to the specific requirements of the FRP profile. The optimized mold structure ensures smooth material flow, complete resin curing, and stable profile dimensional control during continuous production.

Pultrusion die design needs to consider the following factors:

Profile cross-section geometry and dimensional tolerance requirements
Resin system curing characteristics
Fiber arrangement and fiber volume content
Pulling speed and actual production conditions
Total mold length and heating zone layout

Through optimized Pultrusion die structure design, issues such as profile deformation, incomplete curing, and surface defects can be effectively reduced.
