Processes

The right processes and technology for your product.

Our comprehensive service and our advisory expertise enable us to partner you from the concept to the finished component, allowing you to benefit from our specialist know-how. What truly sets us apart is our ability to put our springs and stampings expertise to use advising you in the development of your application and then to define the right process and technology for your product. We deliver exactly the functionality and quality you need at optimum cost.

Phase 1: Planning

PROJECT MANAGEMENT
PROJECT MANAGEMENT

Our project manager is your key point of contact for the entire project. Not only are they all specialists in springs and stampings, they also boast wide-ranging technical know-how in the customer applications they support. This is how we are able to ensure that you always get the optimum customer care and advice.

Advanced process and quality planning is done in accordance with APQP and VDA guidelines.

PRODUCT DEVELOPMENT
PRODUCT DEVELOPMENT

Our engineers are skilled in product development and very familiar with the material, spring technology and customer applications. They have modern development tools such as 3D-CAD and FEM simulation at their fingertips. Prototypes are manufactured on serial production machines. We develop and build the special machinery and tools we need ourselves.

PROCESS DEVELOPMENT
PROCESS DEVELOPMENT

Process development for the entire BAUMANN Group is coordinated by a team of specialists responsible for launching new technologies, optimizing individual processes and process chains. So we can ensure the transfer of knowledge throughout the group and standardization across the world – and for our customers that means optimum costs coupled with global production standards.

MACHINE DEVELOPMENT
MACHINE DEVELOPMENT

Our BAMATEC machine manufacturer embedded within BAUMANN Group enables us to produce our own coiling and testing machines to facilitate our manufacturing operations. Boasting this level of vertical integration puts us in a position to continually optimize and perfectly design machines for large volume requirements. BAMATEC handles all of the mechanical and electrical engineering design and software programming completely in-house, which enables the machine development department to define and modify even complex systems down to the last detail. An end-to-end data flow from SolidWorks and CADdy to SAP using CIDEON keeps the organization lean.
