Fiber-reinforced composite innovations from Dieffenbacher

Proportional valve technology ensures infinitely variable control of the press force and a speed optimized for the process in question. Thanks to customized control technology, the press can fulfill the quality demands placed on components. Quality control through process data acquisition and archiving makes the manufacturing process transparent and guarantees reliable production.

Compress Lite: The New Press Series

Flexible press and automation systems are crucial to ensuring that fiber-reinforced plastic components can be produced in a cost-effective manner. Dieffenbacher has developed the new Compress Lite press series in order to satisfy this requirement.

The press, which is available in an upstroke and short-stroke design, boasts a low construction height and an energy-saving drive. The identical deflection of table and ram, which provides an even bend flow of the upper and lower tool, and high-precision parallel-run behavior ensure a consistent component thickness and increase the quality of the component.

The exceptional ease of access on all four sides of the press enables rapid, flexible die changes using moving bolsters as well as optimum clearance for automation tasks.

The press series is designed for pressing fiber-reinforced thermoplastics and thermosetting plastics, as well as carbon fiber-reinforced plastics.

The Compress Lite is available in variants delivering press forces from 4000 to 12,500 kN. The new press design compliments Dieffenbacher's existing press range, which includes the Compress Plus and Compress Eco series.

Compress Plus: The Energy-Saving Press Series

Constantly increasing energy prices are calling for energy requirements to be reduced through the efficient and economical use of valuable resources. Ecologically sound production processes protect the environment and reduce costs. The energy-saving Compress Plus press series is Dieffenbacher's response to changes on the market and safeguards customers' ability to compete.

The Compress Plus is primarily used for LFT-D and SMC applications and allows top quality components to be produced thanks to high-precision dynamics and process reliability. The series is supplied in variants delivering press forces of 15,000 to 50,000 kN and bolster sizes from 2400 x 1800 mm to 4000 x 3000 mm.

The short-stroke cylinder system allows energy requirements to be cut by 50%, making it possible to achieve closing speeds under load of 80 mm/s and therefore cycle times of approx. 20 secs., depending on the press force.

A variable control system means the press can be adjusted to different material characteristics, ensuring process-optimized parts production that can also be documented. Speed, low energy requirements and optimum control allow for an efficient, and therefore economical, production process.
