By developing tailor-made, high-efficiency equipment, Engin Plast enables its clients to drastically reduce waste, lower environmental impact and improve overall process stability
Effectively managing production waste remains one of the most critical challenges in the plastics industry, with direct implications for both operational costs and environmental sustainability. At every stage of plastic processing – whether it be moulding, extrusion, blow moulding, or thermoforming – a certain amount of scrap or off-spec material is inevitably generated. This may include defective parts, excess sprues and runners, startup waste, or inconsistencies in colour and thickness. In the past, such material was typically discarded, leading to increased disposal costs and a greater ecological footprint.
Engin Plast, a trusted leader in circular economy technologies, addresses this issue by offering comprehensive turnkey systems specifically engineered for the transformation and reuse of plastic production waste. These innovative solutions allow manufacturers to reintegrate reclaimed materials directly into their production lines – particularly extrusion – without undergoing regranulation, a process known for its high energy consumption and longer processing times.
Through the development of tailor-made, high-efficiency equipment, Engin Plast enables its clients to drastically reduce waste, lower environmental impact, and improve overall process stability. The result is a more sustainable production cycle characterized by uniform material blends, reduced resource consumption, and enhanced long-term performance.
The complete range of Engin Plast solutions
Grinding of production waste
The TRIX granulator series covers capacities from 50 to 3000 kg/h. Key benefits include:
• Innovative blade profiles to improve cut quality and reduce wear;
• Durable screens for better material flow;
• Advanced soundproofing and safety systems;
• Low energy use and high reliability.
• Supporting systems include automatic big bag filling stations and conveyor belts for continuous, high-throughput operations.
Customized storage, extraction and dosing
Modular dosing units (e.g., TRIO, DG1SP, DPM) use volumetric and gravimetric technologies to ensure:
• High accuracy and consistency;
• User-friendly operation;
• Efficient use of raw materials and energy.
Components include load cells, precision mechanics, and microprocessors. Big bag emptying systems and hoppers are equipped with petal agitators and electro-pneumatic pistons for smooth flow, even with compacted or challenging materials. Conveying systems – screw or pneumatic – transport regrind or granules to dosing units or extruders.
Extruder feeding: Direct or via intermediate mixer
The AF series forced feeders manage hard-to-flow or bulky materials like flakes, powders, and scraps. Installed at the extruder inlet, they:
• Prevent feed interruptions;
• Maintain steady material density;
• Enhance extrusion line efficiency and productivity.
Automation, supervision, and process control
Engin Plast also offers advanced automation and supervision systems, enabling:
• Real-time monitoring and control;
• Data collection and analysis;
• Full Industry 4.0 interconnectivity.
These systems improve productivity, traceability, and plant efficiency.
