At Fakuma 2026, WITTMANN will present the patented EcoFritz clamp, an injection-molded product for material supply system in injection molding. At its booth, the EcoFritz clamps will be manufactured live with WITTMANN’s injection molding machine and equipment.

EcoFritz clamp: Replacing cable ties for less waste

In injection molding, when material supply system is fully installed, countless cable ties have been used. Many are thrown away because they cannot be repositioned without being damaged.

WITTMANN’s EcoFritz clamp solves this waste problem. The patented clamp firmly attaches media lines and cables to corrugated hoses. Unlike cable ties, the clamps can be removed and repositioned as often as needed.

EcoFritz clamps are available either in conjunction with auxiliary equipment or separately. They are manufactured in three different sizes to fit all commonly used corrugated hoses.

Live demo: EcoFritz clamps produced on “Ingrinder” work cell

At Fakuma 2026, the EcoFritz clamps will be manufactured live inside an Ingrinder work cell, which integrates the injection molding machine, the robot, the conveyor belt and the granulator for in-line recycling of sprues and production scrap into a single unit.

The equipment used to produce the EcoFritz clamps will include a servo-hydraulic SmartPower 60 injection molding machine, a WX90 servo parts removal device and an S Max granulator.

Inside a 2-cavity mold supplied by Röttger, a glass-fiber-reinforced polyamide is processed using the Airmould gas-injection molding technology. The sprue is ground up directly in the production cell and mixed into the raw material as recycled content. This is a closed-loop material cycle. The sprue is recycled immediately without ever leaving the production cell.

Effective dedusting for reusing recycled materials

Material transport is handled by a Feedmax Clean vacuum loader, which WITTMANN has specifically equipped with a very powerful dedusting system to meet the demands of the circular economy.

When transporting recycled material, the Feedmax Clean achieves separation rates of up to 80%(for particles < 1000 µm), thus removing more dust particles and fine parts than any other comparable product on the market.

Digital assistance system to ensure high quality consistency

The digital assistance system HiQ Flow continuously analyzes the viscosity of the melt during the injection phase, supporting high quality consistency in injection molding.

If the measured value deviates from the set value, HiQ Flow immediately adjust the changeover point and the holding pressure within the same cycle. The result is a constant part weight in every cycle. In this way, any fluctuations in the raw material or in the environmental conditions are compensated before even a single piece of scrap is produced.
