Circular Economy in injection molding

Efficient plastics recycling - sustainable production

Together with other companies in the industry, ENGEL has been actively involved in the area Circular Economy and the reduction of the CO2 footprint for years. This goal requires close cooperation across the entire value chain. For ENGEL, supporting our customers along the entire product life cycle is a key concern: from component design and sampling to production, maintenance & service.

Efficient complete machine solutions

Intelligent assistance systems

Technologies for plastics recycling

Each participant in the value chain has a specific role. As an injection molding machine manufacturer and system supplier, ENGEL takes responsibility for three areas: The overall efficiency of the injection molding production cell, the digitalization of injection molding processes and processing technologies.

Advantages of working together with us towards a Circular Economy
Efficient production systems help reduce the CO2- footprint

Whether servo-hydraulic, hybrid or all- electric: ENGEL injection molding machines are among the most efficient in their size and performance class. Servo-hydraulic machines already consume less than 60% of a hydraulic injection molding machine with a fixed displacement pump. Compared to that, the power consumption of all-electric injection molding machines can be reduced by more than half on average. Furthermore, with a precisely matched temperature control solution, there is even more potential for energy savings.

Digitization for increased energy efficiency

The self-optimizing injection molding machine is a key driver of Circular Economy. The aim is to avoid scrap and increase energy efficiency. Digital solutions from our inject 4.0 program help compensate for changes in material quality or other factors that influence the process. This also means that recyclates can be used for a broader range of applications than before.

Consistent high product quality with recycled material

The processing of plastic waste usually requires less energy than when starting from fossil resources. The use of recyclate, therefore, has a direct positive effect on the CO2 balance sheet. This is why ENGEL's in-house development focuses on solutions for recycling and upcycling. Successful examples include the skinmelt and foilmelt technology with up to 100% pelletized recycled material or the two-stage process in which plastic waste is processed as regrind directly after grinding.

Extend the machine service life with simple upgrades and retrofits

ENGEL offers retrofits and supports with the appropriate disposal of the machine. Our goal is to develop sensible concepts to upgrade dated machines with more energy-efficient drive or control systems, for example. This way, inefficient machines can be refurbished, and the service life of the equipment can be extended.

Learn how to get better quality when processing recyclate

Molding complex products and processing recycled material can be challenging. Training is an important measure to ensure efficiency. ENGEL's Circular Economy training courses cover topics like reducing of wear on materials or correctly using and handling recyclates. ENGEL also offers analyses and consultations, especially for recycled materials, which have higher variations in their properties.

Circular Economy involves all market participants. For the process chain to function seamlessly, it is important that each individual step within the overall process is economical. At this point, the circle closes to the optimization of energy consumption, CO2 balance and costs. The plastics industry must act quickly and take advantage of the opportunities opened up by innovative technologies.

Innovative projects in the area of Circular Economy

100% recyclable e-bike frames, Frisbees made from old collected caps, and transport boxes made of over 50% recycled core material: We develop Circular Economy solutions for and together with our customers that are ready for everyday use.

    • technical moulding
    100% recyclable e-bike frame

    The first completely injection-molded bicycle frame with advanced thermoplastic composites is 100% recyclable.

    • technical moulding
    Transport boxes with recycled core material

    With ENGEL skinmelt technology, up to 50% recycled material can be used in the core of this transport box.

    • technical moulding
    Frisbees from recycled beverage caps

    Beverage caps collected at the JKU Linz campus were recycled and processed into Frisbees to demonstrate Circular Economy with a simple example.

Customer AVK uses two-step process by ENGEL to increase efficiency

ENGEL's two-stage process means that a complete process step can be saved when processing plastic flakes, because the recyclate is molded without granulation. The company AVK Plastics BV uses this technology to produce new pallets from recycled material. This technical innovation increases production efficiency and saves valuable energy.
