(VA-) RTM

Resin Transfer Moulding (RTM) is an advanced manufacturing process in which a 2-component resin is injected into a pre-processed mould containing a package of dry fibres. This process begins with preparing the mould and placing the dry fibres. The resin is then injected into the mould under pressure, fully impregnating the fibres. After a certain period and at a specific temperature, the resin polymerizes, resulting in a strong and durable composite product.

Vacuum Assisted RTM (VA-RTM) is a variant of the RTM process that uses vacuum to draw the resin into the mould. This is particularly useful for producing large products (>1 m²). The vacuum helps to remove air bubbles and ensures better distribution of the resin, leading to a higher quality end product.

Advantages of (VA-) RTM

High mechanical properties

Products manufactured using RTM and VA-RTM exhibit excellent mechanical properties, such as high strength and stiffness. This makes them suitable for applications where durability and reliability are essential

Suitable for large and complex products

The process is ideal for producing large and complex shapes that are difficult to achieve with other manufacturing methods. This makes it suitable for a wide range of industries, including aerospace, automotive, and medical equipment.

Ideal for small to medium quantities

RTM and VA-RTM are cost-effective for producing small to medium series. This means the process is flexible and can be tailored to the specific needs of the customer without requiring large investments

No or minimal post-processing required

Products manufactured using RTM and VA-RTM often have excellent surface quality and precise dimensions, requiring little to no post-processing. This saves time and costs in the production process.
