Insights into the success stories
of our customers.

Iterative product development and project management

The challenge

The project with a medical technology manufacturer started at a very early concept stage on the basis of a specification sheet, but without a clear definition of the geometry and the material to be used.

Solution

Together with the customer's development department, GUME worked out an optimal solution in an iterative process and 14 component adaptations. Due to the close coordination between internal toolmaking and elastomer production, iterations could often be implemented within the same weeks.

Result

The rapid iteration and close interaction as a development partner ensured a high level of development reliability despite the time-critical and complex task. The development and release times were significantly reduced and a production- and therefore cost-optimised design was developed.

Setting up dual sourcing for a critical component 

The challenge

The manufacturer of measurement technology purchased a critical component in large quantities from a single source. This led to dependency and the risk of a complete production shutdown in the event of a supplier failure. Earlier attempts to establish a second supplier failed due to the technically demanding production process.

Solution

Due to the challenging properties of the component, GUME involved external specialists in the development process. Thanks to a structured development process, it was possible to achieve the desired component properties over several iterations and test cycles.

Result

The customer now has a secure supply chain with GUME as a second supplier and additional resilience. Purchasing also benefited from cost improvements due to competition and the ability to place quantity structures flexibly.

Express service to avoid a production stop 

The challenge

The previous rubber parts supplier of a crane manufacturer was in danger of failing, with the risk of a production standstill due to missing components. In order to safeguard production, a new supplier had to be established within a very short space of time and several new moulds had to be developed.

Solution

GUME prepared a quotation for the components concerned within one working day. Qualification as a new supplier, including documentation and an on-site visit, took place within a week. Thanks to the integrated express design and production of the moulds at GUME, the first components were delivered just two weeks later.

Result

The supply of parts was ensured thanks to the rapid implementation and tool development and production downtime was avoided. The customer quickly gained planning security and reduced the risk of further delivery failures.
