We test your innovations

We define goals, design prototypes and check quality, barriers and feasibility - with you. Whether medical or pharmaceutical application, fiber packaging or polymer product, our team will guide you quickly, transparently and competently through each and every phase.

Why a
proof of concept
at Kiefel?

  • Full process support

    We give you everything from a single source, from the idea to the pre-series.

  • Material R&D

    We test your materials for weldability, printing, lamination and more.

  • Mechanical engineering with practical relevance

    We test your ideas on real machines. This is how we find the best solution for your application.

  • Reliable upscaling

    If it works in the proof of concept, it will also work in series production. This gives you planning security and flexibility.

  • Sustainable solutions

    We use compostable, recyclable or bio-based materials and reduce your material consumption.

  • Strong network

    We work with leading material manufacturers and development partners for fast, customized, complete solutions.

Concept & Framework

Together with you, we define the goal of your project.

Our experts develop initial design proposals and check the feasibility of your product idea

02

Proof of Concept

We investigate whether the planned product design and geometry are technically feasible. To do this, we can adapt existing process steps and develop new ones.

A proof of concept is as a powerful tool for risk reduction, especially for rapid market launches.

Testing using real materials (e.g. fiber, laminate or composite films) show how the product behaves in practical use.

We measure important properties such as sealing strength, barrier values ​​(OTR/WVTR), leak-resistance and peel behavior.

We then decide together: Is the concept ready for the next step or are adjustments necessary?

03

Upscaling

Our (laboratory) machines allow us to produce, among other things, initial pre-series samples.

At the same time, we define the quality standards and barrier requirements.

Knowledge transfer & production start

Our design and manufacturing teams ensure smooth implementation.

Your new system will first be commissioned at our location and then on-site at your location.

Your team receives practical training – for efficient, safe processes from day one.

This means you are perfectly prepared for series production using your Kiefel machine.
