HP-RTM Injection Machine | High-Pressure Resin Transfer Molding Solutions

In the wave of modern manufacturing that prioritizes efficiency, sustainability, and lightweighting, composite materials are playing an increasingly vital role. At the heart of producing high-quality, mass-volume composite parts lies High-Pressure Resin Transfer Molding (HP-RTM)—a technology in the spotlight. Our high-performance HP-RTM Injection Machines are engineered specifically to meet these advanced manufacturing demands.

What is an HP-RTM Injection Machine?

HP-RTM is an advanced closed-mold composite manufacturing process. The HP-RTM Injection Machine is the core equipment of this technology. It precisely and rapidly injects a low-viscosity epoxy resin system into a sealed mold containing pre-placed fiber reinforcement under high pressure. This ensures thorough fiber impregnation and rapid curing, resulting in high-precision, high-quality composite parts with two smooth finished surfaces.

Compared to traditional methods like hand lay-up or vacuum infusion, HP-RTM significantly enhances production efficiency and part consistency. It is perfectly suited for high-volume, fast-cycle production of structural components in industries such as automotive and aerospace.

Core Advantages of Our HP-RTM Injection Machines

1. High Pressure & Speed for High Efficiency
   Our machines feature an ultra-high-pressure injection system capable of delivering resin in an extremely short time. This drastically reduces cycle times and revolutionizes production rates, meeting your needs for large-scale industrial manufacturing.

2. Precision Metering & Homogeneous Mixing
   Equipped with high-precision gear metering pumps and multi-component static mixers, our units ensure resin and hardener are mixed at an exact ratio with a homogeneity exceeding 99%. This guarantees outstanding and consistent final part quality from the source.

3. Intelligent Control for Ultimate Reliability
   Integrated with advanced PLC or Industrial PC control systems, our machines provide real-time monitoring and precise control over critical parameters like injection pressure, flow rate, temperature, and ratio. The user-friendly HMI allows for easy operation and storage/recall of process recipes, ensuring perfect reproducibility for every production run.

4. Robust Clamping Compatibility
   Our machine design fully accounts for the high clamping forces required in HP-RTM processes. They integrate seamlessly with high-pressure presses, ensuring mold stability and perfect sealing during injection to prevent leaks and produce parts with superior structural integrity.
