HP-RTM Preforming Line Solution
The Haifeng HF-HPM HP-RTM fully automatic preforming line covers multi-layer unwinding, automatic cutting, infrared heating and preforming, providing an automatic solution for thermoset matrix continuous fiber products before molding. In the High Pressure Resin Transfer Molding process, resin is counter-current mixed under high pressure and injected into a vacuum-sealed mold preloaded with fiber reinforcement. Preforming pre-presses flat fiber fabric into a three-dimensional preform close to the product surface under heating, ensuring fiber content and lay-up direction meet design requirements during injection, with up to 6-layer synchronous unwinding and ultrasonic flash trimming accuracy of ±0.2 mm.
100% Fully Automatic
From multi-layer unwinding to preforming with stable cycle time, minimizing manual labor and human error.
High Precision & Consistency
Ultrasonic flash trimming accuracy of ±0.2 mm with uniform infrared heating for consistent preforms.
Customized to your fiber reinforcement and part size, the line is delivered as a turnkey project with process planning, commissioning, training and after-sales support for mass production.
Production Process
All steps are automatically linked by the control system to keep the preform stable before injection molding.
Synchronous Fabric Feeding
Up to 6 layers of fiber fabric are unwound synchronously with independent tension control and alignment for consistent multi-axial lay-up.
Automatic Contour Cutting
Ultrasonic cutting performs contour cutting and flash trimming with smooth edges, with programs generated automatically from the product model.
Uniform Fabric Heating
A robot grips and handles the fabric while the infrared heating furnace softens it to the set level with accurate, uniform temperature.
