Robotic Molding Of Composite Parts

Robotic molding

GEBE2 produces robotic equipments for the molding of composites:

Ultrasonic cutting of raw or prepreg tissue
Ultrasonic welding of thermoplastics
Preforming
Patch handling and lay-ups
Robotization to load and unload presses on RIM / RTM / SMC / Stamping processes.

Examples of robotic molding applications

COMPRESSION MOLDING: SMC

The SMC (Sheet Molding Compound) is a semi-finished product containing chopped reinforcement fibers and resin, with the added advantage of very fast press-processing times. GEBE2 produces robotic cells for loading raw materials into molds, unloading parts and finishing.

PRESS CASTING: RIM (REACTION INJECTION MOLDING)

As part of the production of two-component polyurethane or polymer parts using the RIM process, GEBE2 offers complete systems that comprise:

The injection machine
Presses or mold carrier
Automated injection by robotic casting or closed mold injection
Automation and end-to-end supervision of the production process

RTM (RESIN TRANSFER MOLDING) PREFORMING AND CURING

These islands enable end-to-end production of a composite part starting from a material blank laid out flat. The production steps are as follows:

Heating the material
Preforming
Material laid in the mold
Mold loaded in the press
Curing on the press with heating trays
Mold cooled and released

ULTRASONIC CUTTING

Using ultrasonic cutters to cut composite materials provides a high level of precision and a perfect cutting quality. The high-frequency vibration of the sonotrode prevents adhesion to the blade, thereby minimizing maintenance interventions, and cauterizes, thus avoiding delamination of the fibers.

When fitted on a robotic system, this SONIMAT technology makes it possible to cut semi-finished products into shape: aramid, Kevlar, honeycomb, nomex, glass fiber, prepregs.

Thermoset: up to 25mm multi-ply with carbon fiber reinforcement
Thermoplastics: up to 6mm of PPS plates with carbon reinforcement
