Cold forming enables the reproducible production of large series and is, therefore, an ideal process for mass production. As the contour of the component is produced by forming and not by removing and previously heating the material, the process of cold forming is a very raw material-efficient technology. Components manufactured in this way have a minimal CO2 footprint.
By using wire diameters from 3.5 mm to 23 mm and part lengths from 50 mm to 600 mm, we achieve a wide range of parts. Multi-stage presses with up to 6 forming stages enable many and high degrees of forming and, therefore, complicated part geometries.
The forming process and the associated significant changes in shape often result in work hardening of the material, which leads to an increase in yield strength and tensile strength, hardness and deformation resistance. Subsequent heat treatment is, therefore, often not necessary. This also creates surfaces with very low roughness.
As the material structure is not destroyed during cold forming and the fibre structure is retained, cold-formed components are characterised by very good fatigue strength.
With cycle times of up to 140 parts per minute, processing times are significantly shorter than with machining.
Using simulation software, we can test new parts and the associated mould design in advance. This allows the general feasibility to be tested and the developed forming tools and the associated forming processes to be assessed. This reduces development time and costs.
The cold forming systems used at our plant in Bremen can process steel from coil and bar in the following dimensional ranges and designs:
High degrees of deformation of up to 70 % can be realised, particularly in the impact extrusion process.
Subsequent machining processes, such as the automated concentricity check and the straightening of the parts, the machining of both ends or eddy current crack testing are carried out directly at Mac Panther in Bremen. The same applies to surface treatment, in which operating and process materials such as oil or phosphate are removed from the formed parts mechanically in vibratory finishing or chemically in washing systems. The finishing processes utilise special storage and feeding techniques, as well as special machines developed by us.
Mac Panther is a supplier of drill blanks in a wide range of dimensions tailored to individual customer requirements. Depending on customer requirements, we also supply the blanks with different processing statuses.
Our customers include brands such as HILTI, Bosch, Stanley Black & Decker, DreBo and many more.
As Mac Panther used to manufacture tools and drills itself for many years, we know the processes and boundary conditions of our customers very well and can, therefore, work with them to optimise the overall process and drive innovation.
The automotive industry is predestined for our production processes, as the focus here is on large series with consistently high quality and low costs.
Our modern profile and thread rolling machines, as well as rotary swaging machines, are used in combination with our forming presses mainly for our customers in the automotive industry.
Our customer base includes Tier 1 companies such as ZF Friedrichshafen.
Our product portfolio consists of long, slim moulded parts. Safety-relevant components, e.g. from the chassis, have also been part of our product range for years.
