A custom RTM mould is necessary if the original model of a component cannot be replicated. It can be very difficult to produce a component with an exact shape using conventional methods. This process reduces voids and increases the mechanical properties of the component. A matched metal tool is required to achieve an exact match. This mould is designed for your specific product and is the best option for a low-volume production run.
This process involves the injection of a low-viscosity thermoset resin into a closed mold. The resin is injected under moderate Custom RTM Moulds Factory pressure into the cavity of the mould, filling any voids and wetting the entire surface of the reinforcing material. This technique is often used in the transportation industry, and is especially suitable for parts with complex three-dimensional forms. To reduce the risk of air escaping, a vacuum bag is placed over the mold’s upper half. The vacuum is then removed and the resin flows into the preform.
An RTM mould can be manufactured using either an infusion or contact method. The process for making these moulds is the same, although the technical flanges are different. A contact mould has a lower cost, but is still more complex, so you need a more expensive mould. However, it’s worth considering the high cost of a customised mould. Then you’ll know that it is well worth the money.
Another important parameter for custom RTM moulds is the resin used in the process. The temperature and viscosity of the resin are crucial, and they must be compatible with the requirements of your part. Your mould can have the exact properties you need and the right permeability to allow the material to flow. This can help you reduce labor costs and improve process control. A good quality custom RTM mould can increase your productivity and quality.
The temperature and permeability of the resins are also very important factors in the RTM process. These variables can vary from one type of material to another. For example, the temperature and permeability of the fibre mats are essential to the final product. You must ensure that the RTM mould has the proper viscosity and permeability to suit your requirements. A low temperature mould can increase the productivity of your business.
