Plants for fiber-reinforced composites

Fiber-reinforced composites – from the RTM process, as Organosheets or as sandwich panels – are in high demand in all high-end industries where lightness and at the same time high fatigue strength during dynamic loads ensure decisive competitive advantage. Siempelkamp has played an important role in the market for composite materials since 1993.

Whether glass-fiber reinforced plastics or carbon-fiber reinforced plastics, this precious material is used wherever the focus is on saving weight, reducing fuel consumption, good corrosion characteristics as well as high stress on the material. The Siempelkamp name stands for solid and precise technologies regarding the presses and handling systems for the production of fiber-reinforced composites.

Plants for the rubber industry

The design and manufacture of presses for the rubber industry is one important core competence of Siempelkamp's machine and plant engineering business unit. It was more than 100 years ago when we placed our first conveyor belt press in the market. Only 20 years later we started up the first large vulcanizing press with closed frame design.

Even today our presses and plants for the rubber industry still provide clear benefits. The long operating life, speed, high availability and efficiency are important reasons why our customers decide to buy a Siempelkamp product.

Presses for the RTM process and Organosheet production

Our 4-cylinder high-tech press for composites is tailored exactly to meet the needs that manufacturers of high-performance composites demand from us: 100% accurate positioning for the forward and backward movement – exact control during shutdown of the press due to precision hydraulics. Another advantage: The press can be operated in open-die as well as closed-die mode. Furthermore, gap impregnation is also possible with this press providing enormous versatility.

Technical features:

excellent pressure distribution inside the press
modular tool changing and clamping system for tool dimensions with heights between 200 and 1,550 mm
direct or indirect tool heating and cooling system

Customer benefits:

high-quality materials for automobile and aerospace industries
economic productionquick tool changing system
possibility to carry out both processes on one press line

Presses for the SMC/RTM process

With the new Siempelkamp press, fiberglass reinforced plastic components can be manufactured for the automobile industry - mainly using the SMC process. The advantages of Siempelkamp's composite technology for the customer are obvious:

High flexibility: With a simple modification, it is possible to change the 2,000 t down-stroke press over from the SMC process to the RTM process. The unique hydraulic control allows the use of many different tools - thus, also contributing to high product flexibility.
Material savings: The new press has a highly precise single cylinder control which ensures high quality for different component shapes and geometries. With the SMC components manufactured on the new Siempelkamp press, smaller tolerances can be achieved than in the past. This pays off: The customer saves up to 20 % in material per component part and with it significant production costs!
High-quality products: Through the movement of the upper press table along the X and Y axes, stress-free closing of the tools and an efficient de-gasing are possible. Thus, the percentage of pores is significantly reduced and product quality improved. The precise positioning of the upper mold allows an adjustment in the 1/100 mm of the mold gap.
High outputs: The tilting of the table has another advantage: Due to the inclined position, for which the upper mold is first lowered near the sprue and then in the riser area to achieve the final shape, the resin can be more quickly and evenly distributed. Next to the improved quality of the impregnation, this also shortens the impregnating time. More parts can be produced in a shorter production period.
Safe production: Next to the press, hydraulics and automation, the complete visualization of all processes as well as of the associated peripheral devices such as the tool heating system and the injection system can be ordered. In this way, the customer can continuously monitor the production. The process data management system DAHMOS, also part of the customer's scope of supply, allows the analysis, evaluation and optimizing of individual press cycles.
