Materials Overview

Different scrap streams behave differently under compression. Springback, geometry, contamination, and downstream furnace requirements all affect bale quality and material value. Logemann engineers baling systems around those material realities so customers can produce denser, more consistent, more furnace-ready output.

Materials We Support

Each material presents a different compression challenge. Select a material to explore baling solutions configured specifically for that stream.

Aluminum scrap requires a compression strategy that accounts for its low bulk density, springback, and high downstream value. The goal is not just to reduce volume, but to create stable, uniform bales that support handling, shipping, and melt performance.

Common considerations include:

lightweight scrap with high springback
furnace-ready bale consistency
improved handling and transportation efficiency
stronger downstream material recovery

Steel and tin scrap can vary widely in thickness, form, and bulk density. These materials require baling systems built for repeatable compression, structural durability, and consistent output across demanding applications.

System design must account for:

varying scrap geometry and density
repeatable bale formation
structural strength under load
downstream transportation and handling demands

Copper and brass scrap carries significant value, which makes bale consistency and density especially important. Systems designed by Logemann help processors protect that value through controlled compression and repeatable bale formation.

Key priorities include:

preserving high-value material
producing consistent bale geometry
supporting stable downstream handling
preparing material for efficient remelt operations

Some scrap streams do not respond well to standard baling approaches. High-springback materials, fine scrap, irregular shapes, and difficult blends require testing, validation, and a compression strategy built around actual material behavior.

These applications often involve:

difficult-to-control springback
non-standard scrap geometry
specialty or mixed materials
testing before full production implementation

Material Science

Logemann’s material science approach focuses on what happens after the bale is made. Bale density, structure, and consistency influence remelt performance, shipping efficiency, and overall scrap value. That is why the company looks beyond force and throughput alone.

Density Matters™

Density Matters™ reflects Logemann’s position that bale density has a direct effect on downstream performance. Scrap preparation should not be judged only by throughput or bale size. It should also be judged by how well the material performs at the furnace.

The initiative focuses on:

remelt efficiency
material recovery
lower oxidation and dross potential
improved shipping and storage efficiency

Density vs Yield

Higher-density bales can help reduce excess air and exposed surface area in the furnace, which may improve melt performance and material recovery. This relationship between bale density and remelt yield is central to Logemann’s materials philosophy.

Material Testing Facility

Logemann supports material validation through dedicated testing capabilities designed to evaluate how different scrap streams respond under compression.

Testing can include:

achieved bale density
springback and rebound behavior
cycle time and stroke performance
hydraulic pressure behavior
handling characteristics
effects of shredding, shearing, or crinkling
