Molding Presses

Langzauner produces and develops customized tailor-made press solutions in various sizes and configurations. Direct or indirect heated molds are clamped manually or automatically on surfaces up to more than 8,000 mm in length. A tool shuttle ensures an automated, quick and stable tool change in just a few minutes. Thanks to the unique servo-hydraulic drive, the presses work with maximum precision and extraordinary energy efficiency. For perfect parallelism, the cylinders are individually controlled.

FAQ

Molding presses are designed for manufacturing demanding fiber-composite components, for example in the aviation, automotive, caravan, sports, aerospace, metal, and defense industries, as well as in the wood industry. Typical applications include structural parts, large-format panels, or complex molded components made of CFRP, GFRP, and other high-performance composites. In combination with suitable tools and automation solutions, both prototypes and high-volume series processes can be mapped on a technologically consistent platform.

Langzauner first analyzes components, tools, process windows, and quantities. Based on this, a molding press is designed on a project-specific basis in terms of pressing force, heating platen size, temperature control concept, and degree of automation. Design, hydraulics, control, and visualization come from in-house engineering. After manufacturing and assembly, commissioning, optimization of process parameters, and training of operating personnel follow. Companies receive a turnkey solution precisely matched to production goals and infrastructure.

Molding presses can be integrated into automated production lines that include, for example, mold tool shuttles, high-bay warehouses, material transfer, cleaning stations, opening stations, and robotics. Mold tool shuttle systems enable fast, automated tool changes in just a few minutes. Interfaces allow injection units, primary heating circuits, or handling systems to be connected. This creates turnkey lines that combine material flow, tool logistics, and the pressing process into one continuous, cycle-time-optimized overall system.

The control software of the molding presses is developed in-house and enables flexible parameterization of pressure, travel, temperature, and time. Visualization solutions clearly display process states, including trend curves and recipe management. Data management and Industry 4.0 interfaces allow presses to be connected to higher-level systems, IoT platforms, or solutions such as perfectDATA. Companies thus receive transparent process data for monitoring, quality verification, and continuous optimization.

For exact parallelism, the hydraulic cylinders are controlled individually and coordinated through active parallel control in a thermoneutral design. Sensors and control algorithms continuously monitor the position of the press platens and compensate for tolerances or eccentric loads. This keeps wall thicknesses, fiber orientation, and curing conditions as constant as possible across the entire mold surface, a critical point for high-quality structural components and demanding composite applications.
