When the time comes for your custom RTM mould to be manufactured, the first step is choosing your design and a material. Vinylester resins are injected into a closed mould containing polymer concrete or other reinforcement material. Finite Element Analysis (FEA) calculations are used to determine the precise dimensions of the finished product. This initial data has been refined and updated over time based on extensive product testing and long-term field behavior. Using RTM technology, Rotec produces manhole covers, panels, and custom-designed flanges.

For high-volume production, a custom RTM mould is the best solution. The process requires a steel or aluminium mould that can be customized to accommodate complex geometries, high-quality materials, and high-volume production runs. With a custom mould, you can maximize your production efficiency and reduce your costs. The most important component in the process is the fibre preform. The mould is closed to contain the fibres and ensure that the resin will not migrate out of the part.


The advantages of RTM manufacturing are numerous. Designed for high-volume production, custom RTM moulds are ideal for large-scale manufacturers. Whether you're a small or large manufacturer, you can count on a custom RTM mould to meet your needs and budget. Made of steel or aluminium, these tools are not too difficult to make and are an excellent option for mass-production molding. The process is a low-cost solution, especially for those with large-scale production needs.

In addition to being economical, resin transfer molding requires a high-quality fibre content. You can expect 60%-75% fiber to resin ratio. The properties of the resin system and precise orientation of fiber are critical to a high-quality product. At Rotec, we have developed and built proprietary RTM technologies. A CNC cutting machine cuts glass fiber material into the shape you need. A preform is then positioned in an open RTM mould.

A custom RTM mould is the most economical way to manufacture highly complex composite parts. The process allows you to produce very large and complex parts while maintaining consistent quality and precision. In addition to ensuring high quality, a custom mould is also cost-effective, with a high ROI and low production costs. Moreover, custom RTM moulds can be made with ease in a variety of materials and can be reused. There are many advantages of a customized mould.

A custom RTM mould can be made of various materials, including steel and aluminium. Generally, steel and aluminium are the most common materials used in custom RTM moulds. It is essential to choose the right material for the mold as this is the most effective way to get the desired shape and quality. If you have a specific requirement, you should consult with your supplier to decide the best materials. Alternatively, you can contact a manufacturer directly to discuss your needs.

A custom RTM mould is a versatile and cost-effective way to manufacture a wide range of parts. Due to the flexibility of the process, you can use the same tool to produce a variety of different components. You can also choose the best resin and material for your production needs. A custom RTM mould is an essential part of a successful production mold. So, don't wait to order a customized RTM mould!

Choosing a custom RTM mould is crucial in ensuring that your end product is unique. It is essential to choose a material that is resistant to wear and tear. The best material for your custom RTM mould should be durable and able to withstand high temperatures. During the process, a resin is injected into the closed mould. After that, the mold is closed, and the process is complete. The result of the molding is a custom RTM mold.

A custom RTM mould is one of the best ways to manufacture complex composite parts. You can make any type of part that requires this type of material. A custom RTM mould can accommodate many different materials and can be used to produce a variety of products. When it comes to custom RTM moulding, a customized RTM mould can be made in just a few minutes. Aside from being affordable, a custom RTM mould can be made in any shape and size you need.
