Process Optimization – Greater Efficiency Through Perfect Screw Geometry
Every extrusion process holds optimization potential. ARENZ makes this potential visible – and usable. With over 55 years of experience in the design of screw geometries for the extrusion and injection molding market, we have the know-how to systematically analyze, evaluate, and sustainably improve your process.
Simulation-Based Process Optimization
Together with a German university, we have developed a powerful simulation software that enables the key influencing variables of your extrusion or injection molding process to be rapidly identified, assessed, and specifically optimized.
Our software delivers precise results on:
- Pressure and throughput calculation
- Melting calculation
- Temperature profile calculation
- Power consumption calculation
- Residence time calculation
- Mixing index calculation
- Feed behavior calculation

Your Benefits – Measurable and Demonstrable
Our customers benefit directly and concretely from the results of process optimization:
- Throughput increase of up to 30% – depending on the existing screw geometry
- Noticeable improvement in product quality
- Flexible processing of different plastics with a single screw
- Targeted minimization of wear and consequently extended service life

Our Optimization Process – Structured and Transparent
From the initial analysis through to the finished screw, we guide you every step of the way:
- Capturing your requirements – joint consultation and definition of objectives
- Current state assessment – systematic recording of all relevant parameters using our proven checklist (plastic, processing method, material combination, screw/barrel)
- Simulation – digital modeling and analysis of your entire process
- Development of the new screw geometry – calculated and optimized based on simulation results
- Presentation – transparent introduction of the optimized solution
- Manufacturing – production of the new screw on state-of-the-art CNC machining centers
ARENZ – Process optimization with a system. For greater performance, better quality, and lower costs.
