Sheet Metal Industry Scrap Choppers Knives for Aluminum, Non-ferrous Metals
Knives for scrap shears and cutting sheet metal are used in pipe production, service centers (steel centers), the automotive industry and factories for the recycling of scrap steel and steel scrap. We offer a wide range of knives for cutting and reshaping various materials, where the geometric accuracy of the knives is essential.
Knives for scrap shears and sheet metal are designed for cutting and reshaping various materials. In such processes the geometric accuracy of the knives is essential as it enables and allows for precise cutting. We produce them with a diameter of up to 600 mm and with a variety of bores needed for clamping on different axes.
We offers scrap choppers in tool steel, carbide, and powder metal. Our choppers are manufactured using state-of-the-art production, finishing, and heat-treating equipment, enabling us to supply tooling of remarkable consistency and reliability. Every scrap chopper is individually inspected to ensure you receive zero-reject quality.
We offer scrap chopper knives for the processing of edge trim and waste strips. All scrap chopper knives are custom made according to drawings or samples. Our engineer can produce drawings according to your sample. Scrap chopper blades are produced from high quality steels such as:
- 1.2379
- 1.2344
- 1.2746
- Tungsten carbide
- cutting of different profiles,
- cutting of scrap iron (for hydraulic and mechanical shears),
- alligator knives.
- Each knife has four cutting edges that require only a standard surface grinder for sharpening.
- Cuts a full range of scrap thickness without the need to adjust knife gap.
- Self-threading entry chutes eliminate threading time and provide safe scrap handling.
- Helical cutting action is quiet (<85db) and results in longer knife life.
- Quick change heads option provides trimmer head replacement in less than 10 minutes.
- Uniformly chopped scrap brings higher scrap value.
- Many models available with patented shimless knife design - no shims required after knife sharpening.
In the production of knives for scrap shears and cutting sheet metal we use materials that provide the durability required in the metal industry.
In addition, we mostly use materials that are adapted for cold cutting. Once they have undergone suitable heat treatment processes, these steels achieve high strength, robustness as well as wear and tear resistance.
