HV Plastcompactor: Agglomeration, Drying and Densification in One Efficient System

Coperion meets these demands with the Herbold HV Plastcompactor – a highly versatile system that combines continuous agglomeration, drying and densification in a single process step.

One Machine – Multiple Process Benefits

The HV Plastcompactor is designed to transform difficulty-to-handle materials into free-flowing, densified products that are easier to store, convey, feed and blend. By increasing bulk density by up to a factor of 20 compared to the input material, the system significantly improves material handling and process reliability.

Its continuous operating principle ensures consistently high production performance at maximum throughput, while high automation levels allow minimal staffing requirements.

Gentle Processing for Premium Product Quality

A key highlight of the Herbold HV Plastcompactor is its ability to sinter material without reaching the melting point. Thanks to low process temperatures and short residence times, the material is treated gently, preserving valuable product properties at minimal thermal stress.

This makes the system especially attractive for recyclers seeking high output alongside premium end-product quality.

Built for Reliability and Low Maintenance

The HV Plastcompactor has been engineered for robust daily operation with low wear costs and easy servicing. Bolted kneading bars can be replaced quickly, reducing maintenance effort and downtime. In addition, the system is largely resistant to foreign objects, helping maintain stable production conditions.

Key Advantages at a Glance

• Continuous agglomeration, drying and densification in one system 
• High throughput under automated operating conditions 
• Precise process control without tool changes 
• Easily exchangeable wear parts for low maintenance costs 
• Improved bulk density and flowability of raw materials
• Processing of damp or wet materials without separate drying equipment 
• Reliable operation with high process flexibility 

Suitable for a Wide Range of Materials

The HV Plastcompactor is ideal for processing materials such as:

• Thermoplastic materials such as fibers, tapes, foams, films, stretch films or thin films, fines, powders, or flakes
• Plastics with low bulk density that are difficult to convey, store, and mix 
• Moist or wet input material can be dried using the HV, eliminating the need for mechanical or thermal drying

Efficient, Flexible and Future-Ready

With the HV Plastcompactor, we offer an advanced solution for recyclers looking to streamline material preparation, improve handling properties and increase productivity. Seeking efficiency, flexibility and product quality, the HV Plastcompactor sets a new benchmark.
