In modern slitting lines, every detail counts. The hpl scrap chopper – also referred to as an edge trim scrap chopper – is a key component in the process chain It delivers reliable, precise and energy-efficient chopping of trimmed edge strips.
As a manufacturer with decades of experience in scrap handling and recycling technology, hpl-Neugnadenfelder develops customized solutions that can be perfectly integrated into both existing and new lines.
Each scrap chopper or scrap chopping unit is engineered specifically for the customer’s application – from strip thickness and material strength to available space and safety concepts.
Thanks to intelligent drive technology, wear-resistant knives and ergonomic design, they ensure maximum process reliability with minimal energy consumption.
Beyond that, hpl stands for fast, practical implementation: projects are delivered in record time, and even during production downtime, our assembly teams are on site – ensuring your line is back in production as quickly as possible.
Our scrap choppers combine robust mechanics with modern control technology and precise edge trim guidance.
Two cutting heads are driven via a shared gearbox system – reducing energy consumption by up to 50% while maintaining consistently high cutting quality.
The servo-controlled knife gap adjustment automatically adapts the knife clearance to the respective strip thickness – fast, precise, and without manual intervention. This significantly reduces set-up time and ensures a precise, low-wear cutting process.
Synchronized drives ensure consistent edge trim guidance and stable strip tension – even with strip thicknesses from 0.6 to 6 mm, strip widths up to about 1,850 mm and line speeds up to 300 m/min. At the same time, our systems process all common ferrous and non-ferrous metals, including steel, stainless steel, aluminum and copper as well as coated or alloyed materials.
Thanks to their compact design, hpl scrap choppers are particularly suitable for retrofits in space-restricted line areas. Existing conveyor or scrap suction (extraction) systems can be seamlessly integrated – without extensive modifications or long downtimes.
The result: solutions that combine efficiency, precision and sustainability durable and energy-efficient systems engineered for minimal maintenance and long service life.
Whether for a new line or a retrofit, every project at hpl begins with a detailed analysis of the existing conditions. Our design engineers consider material properties, strip tension, safety requirements and ergonomics before taking the first design step.
This approach leads to tailor-made solutions that prove themselves in practice – durable, efficient, low-maintenance and operationally safe.
At hpl, engineering expertise runs deep – from the knife assembly to the control system.
And that’s what truly sets us apart: we don’t just deliver products, but complete solutions that measurably improve your processes.
