HP-RTM Tooling
High Pressure Resin Transfer Molding.
Short Cycle. High Volume. Class-A Surface.
Next-Gen Composite Manufacturing
HP-RTM (High Pressure Resin Transfer Molding) is an advanced molding process technology introduced for the mass production of high-performance thermoset composite parts. It involves injecting resin mixed with a catalyst under high pressure into a closed mold pre-laid with reinforcing fibers (such as Carbon Fiber or Glass Fiber).
Unlike traditional RTM, HP-RTM utilizes high-pressure mixing injection (1.0-15.0 MPa) and vacuum-assisted exhaust. This combination significantly reduces porosity, improves wetting, and shortens the curing cycle to just 3-5 minutes, making it a viable option for high-volume automotive production.
Why HP-RTM?
"If you need to manufacture large parts with a high strength-to-weight ratio and Class-A surface quality, HP-RTM is the process you need."
Process Advantages
"Low-cost, short-cycle, and high-quality production can be achieved through our HP-RTM solutions."
Fast Cavity Filling
High injection pressure (up to 15 MPa) and low-viscosity resin ensure rapid filling, shortening the cycle to minutes.
Short Curing Cycle
High-activity resin systems combined with high-temperature molding environments greatly accelerate the reaction rate.
Low Porosity
Vacuum-assisted exhaust technology effectively reduces pore content and improves fiber impregnation quality.
Excellent Surface
Using high-finish molds and in-mold coating technology enables parts to achieve Class-A surface quality directly.
Dimensional Accuracy
Double rigid mold surfaces and large-tonnage pressing ensure precise thickness control and minimal shape deviation.
Self-Cleaning System
Internal mold release agents and self-cleaning mixing heads improve equipment efficiency and reduce maintenance.
High Repeatability
Automated gap injection and post-injection compression processes reduce defects and ensure consistent part quality.
Cost Efficiency
Reduced resin waste and faster cycle times make HP-RTM a cost-effective solution for mass production.
HP-RTM Applications
Driving the future of lightweight mobility.
Visual Carbon Parts
Roof panels, hoods, and spoilers where the carbon fiber weave is visible, requiring flawless surface finish.
Structural Components
Monocoque chassis parts, floor pans, and B-pillars providing maximum stiffness with minimum weight.
Complex Geometries
Parts with compound curves and integrated inserts that are difficult or impossible to produce with metal stamping.
