Micro Extruder ZE5: High Versatility in a Small Package

The ZE 5 HMI mini micro extruder, in its compact table-top format, stands as one of the smallest twin-screw extruders available on the market, offering remarkable versatility despite its size. Designed with flexibility in mind, it can be equipped with a wide range of features similar to its larger counterparts, making it an excellent choice for laboratories and small-scale production facilities.

This micro extruder system is especially beneficial during the early development phases of new products, where only limited amounts of active ingredients are available. Notably, the ZE 5 can process as little as 1 gram of material—far less than most other micro compounders (for instance, the Xplore MC 15 requires a significantly larger sample). By producing an extrudate weighing just 0.75 grams, the unit minimizes material waste while ensuring high-quality output. This precise handling of small quantities makes the ZE 5 HMI an invaluable tool for micro extrusion research, formulation testing, and prototype production.

The extruder is highly customizable, offering several options to enhance its performance. For example, it can be equipped with water, air, or liquid-nitrogen cooling, providing temperature control that is crucial when working with heat-sensitive materials. This adaptability ensures that the extruder can handle a wide range of substances, from polymers to specialized compounds, without compromising their integrity during processing.

Additionally, the ZE 5 HMI features optical pressure measurement at the die, delivering real-time data for monitoring and adjusting the extrusion process. This capability allows for better control over processing parameters, improving consistency and overall product quality. Integrated liquid feeders supply raw materials continuously and uniformly, further enhancing efficiency and reliability.

One of the key highlights of the ZE 5 HMI mini micro extruder is its 5 mm twin-screw co-rotating design, which can be customized with different screw segments to suit diverse processing needs. These segments enable conveying, kneading, mixing, compacting, pressing, decompressing, or reverse conveying, making the extruder suitable for applications ranging from basic compounding and reactive extrusion to complex material processing.

In conclusion, the ZE 5 HMI micro extruder is an ideal solution for anyone needing a compact yet highly capable extrusion system for small-scale production or research purposes. Its small footprint, combined with customizable features, delivers optimal performance even when handling minute quantities of active ingredients or specialized materials. Whether for R&D, formulation testing, or prototype production, the ZE 5 HMI offers the flexibility, precision, and efficiency required for successful micro extrusion and compounding.
