Custom RTM moulds are an excellent way to produce the most complicated and intricate parts. The process involves the injection of vinylester resins into a closed mould containing reinforcement material, such Custom RTM Moulds supplier  as polymer concrete. Using Finite Element Analysis (FEA), these products are precisely sized, and their properties are determined by careful measurement of the fibre orientation. The RTM technology is used to produce custom moulds, including manhole covers, panels and flanges.

The process of RTM is a manual one, which can involve almost any reinforcing material. The process requires a core, cavity, and tools, which can be made of composite materials, aluminum, or stainless steel. As a result, the resin-infused part has excellent surface finishes. In some cases, a gel coat is injected into the mould cavity to improve the finish. This creates a paint-ready surface.

The RTM process consists of five distinct phases. Rotec moulds are made of aluminium or steel. The glass reinforcement is placed in layers within the open mould. Each layer has a predetermined size, weight and shape. The closed mould is clamped by a hydraulic press. High-pressure injection and high-temperature curing cure the resin inside the mold. Once the resin is inside, the mould is ready for injection.

The RTM process uses closed moulds to force the resin into the cavity. Depending on the requirements, the moulds can be made of steel, aluminum, or other materials. During the second phase, the mould is closed and layers of pre-cut fiberglass reinforcement are placed inside. Each layer is pre-cut and pre-determined for each product. Finally, a hydraulic press applies clamping force to the closed mould. The resin is injected by a high-pressure injection, and the mould is cured by applying heat.

The RTM process is a manual process. It allows the use of almost any type of reinforcing material. The RTM process uses a variety of types of tools, including metal and composite materials. The finished parts from this process have extremely good surface finishes and are perfect for paint applications. The RTM process can be automated, as well as fully manual. Regardless of the procedure, the RTM process can be a highly productive and cost-effective way to manufacture a wide variety of products.
