Are you interested in stamped-bent parts and flat-form springs? We are also at your disposal with our know-how and years of experience to develop individual specialized springs.
Replace Expensive Turned or Deep-Drawn Parts With Stamped-Bent Parts.
High-quality stamped-bent parts, cylindrical or in other geometric shapes replace expensive turned or deep-drawn parts.We manufacture high-quality stamped-bent parts as cylindrical bodies, also called rolled bushings. They are used to replace your previous expensive turned parts or deep-drawn parts. Such bushings are used, for example, for press-fitting or injection moulding in plastic and metal housings. Our bushings are preferably available in stainless steel X5 CrNi 18.10 or in material DC 01, optionally also with corrosion-resistant coating. For your customised application, we also manufacture the bushings from other materials, for example hardened spring steel, or in deviating geometric shapes. Please contact us!
Edge Finishes of Band Steel/Flat Material as Pre-Material for Rolled Bushings
We produce rolled bushings cost-effectively in the stamping process from the running material coil. Subsequent chamfering by machining is not needed. Choose the best edge treatment for you on the band material used:1. Edge Processing With Material Removal: Chasing or Tool Rounded
The band edges are machined with hard metal plates. This process is called tool rounding. The edges can be tool rounded, single or double tool rounded.
2. Edge Processing Without Material Removal: Rolling or Roll Rounding
The edges of the material are rolled round. That is why this process is called roller rounding. It is suitable for “softer” band material for which chasing cannot be used.
We prefer to use slightly softer material for bushing production, which is more suitable for the high degree of forming. To achieve the hardness required for your application, we can subsequently thermally harden the bushings.
We are also happy to manufacture stamped and bent parts for your application. Our engineers are happy to contribute their experience to your product development process. Together with your specialists, we will find an optimal balance of function, design and cost for your technical springs or bent parts.
