Kraus Maffei’s reaction injection molding department (hereinafter referred to as “Klaus mafi”) and Diefenbach (DSE) group company (hereinafter referred to as “Diefenbach”) signed a sales cooperation agreement on high-pressure resin injection molding system (high-pressure RTM) to provide a turnkey solution of high-pressure RTM technology for the global market.

With the acceleration of the development process of electric vehicles and hybrid electric vehicles in the automotive industry, carbon fiber reinforced plastic parts are facing an increasing market demand trend, and high-pressure RTM technology plays a key role in the production of carbon fiber reinforced plastic automobile parts.

It is reported that in the production of fiber intermediate products (woven and non-woven fabrics), vertical presses need to be used.

Generally, the mold located below allows the fiber fabric to be placed into the mold under the action of heavy force. Epoxy resin or polyurethane can be injected into the mold by using the square high-pressure mixing head installed on the mold.

During the curing process, the mold cavity pressure force ⼀ can generally be as high as 100bar (101.45kg / cm2). An important function of the cooperation between Kraus Maffei and Diefenbach is to further improve the process technology, for example, shorten the reaction (curing) time, which will help the parts processing industry and commerce to improve the high yield and obtain the return on investment as soon as possible.

For customers, they can gain two major advantages: the alliance of the two companies has the ability to provide turnkey solutions for global customers. At the same time, customers only need to contact one partner to obtain all the elements of the production system, which can save time and reduce workload.

The two partners have outstanding technical expertise in their own special technical fields. Diefenbach is ⼀ a system supplier that can provide material handling systems, cutting equipment, perform and molding technology at the same time,

Kraus Maffei is a system supplier that can provide post-forming process technology, cutting equipment, and molds at the same time.

In this cooperation, Diefenbach mainly provides hydraulic molding press with oil cylinder precision parallel control technology, while Kraus Maffei mainly provides a resin metering system and mixing head for epoxy resin and polyurethane.
