Course Overview As a process technology, Resin Transfer Molding (RTM) and Vacuum Molding (VM) offer enormous potential for quality and productivity improvements over the open molding or similar composite molding processes. The use of RTM or VM will remain below its optimum potential to serve the industry unless the industry has full access and awareness to these three key essential ingredients. A source of proven, affordable technology to enable an FRP fabricator to quickly build inexpensive, accurate tooling in house. A source of on-going support to the fabricator in the form of a comprehensive package of RTM and VM peripheral products and services.

The availability of inexpensive but versatile and reliable injection equipment. JHM Technologies, Inc. Is solely dedicated to the Resin Transfer Molding industry by providing intensive, hands-on training courses for the design and construction of low mass composite tools based on proven techniques developed over the last 30 years. The JHM Technologies team has developed low-mass composite tooling technology that overcomes the limitations associated with traditional RTM molds, by reducing weight and typical cavity consistency problems, while offering methods for extending the tool-life.

History has proven worldwide that RTM tooling can be built in-house by the FRP fabricator at low-cost and high accuracy once they have attended our program. Our mold building courses provide comprehensive instruction in building RTM tools for simple industrial parts to complex and dimensionally accurate, cored structures for production in any of the large range of resin systems.

The course will address all aspects of RTM mold design, construction and injecting parameters. The course is an intensive theoretical and practical program with two days of lectures and demonstrations. It is based on proven technology and is designed to provide attendees with the knowledge and techniques required to immediately and confidently apply RTM to their individual requirements. Class size is strictly limited to ensure that each in attendance obtains the full program benefits and has access to individual attention.

The RTM Tooling course is not just for FRP fabricators, but also for suppliers of materials and equipment. Our world-class specialists run all of the courses. What You’ll Learn. Local in tool accuracy to the highest tolerances. Incorporate low voltage close to surface heating in the tool faces, as well as, internal circulating systems that both heat and cool for precise temperature control in high volume applications. Overcome complicated product shapes involving undercuts and high aspect ratio geometries. Make products with accurate foam cores.

Build in sensors for process monitoring and added control. Learn just how uncomplicated the RTM or VM processes and building their related tooling can be. All attendees receive a comprehensive manual. What Will We Cover?

These topics and many more in detail throughout the course Understanding the positive injection pressure RTM process: Injection pressure, flow rates, fill times and their effect on tool design and construction. Process considerations of resin flow paths working from center and edge point injections, advantages of each will be covered. Low mass verses heavy tooling: Effects of temperature on tool life and problems associated with thermal mass. Advantages of Low Mass tooling will be covered as it relates to the capital equipment needed in comparison to the Heavy tooling options. Pattern design and preparation: Flanges, draw angles, and undercut or “die lock” consideration wil be covered in detail.
