Our plastic parts manufacturing processes
Knauf Industries, a manufacturer of custom plastic parts, transforms your ideas into concrete solutions thanks to its expertise in plastics engineering and raw material processing.
Thermoforming
Thermoforming allows us to produce custom plastic parts from rolls of extruded material. This process is particularly suited to medium and large production runs and specific requirements. This solution offers great design flexibility, enabling us to meet all your needs without compromising on strength and consistency.

Foam molding
The molding of cellular foams allows for the design of lightweight and resistant parts thanks to an optimized internal process. This process, which is particularly suited to technical parts as well as protective, cushioning, and industrial packaging solutions, is carried out at Knauf Industries using EPS, EPP, or circular materials. Other even more specialized materials are also available.
Parts produced by molding cellular foams can offer a wide range of features and benefits depending on your needs: lightness, shock and load absorption, thermal and acoustic insulation, mechanical strength, etc.

Plastic injection molding
Plastic injection molding is a high-precision process used to manufacture premium technical parts in both small and large production runs. It guarantees excellent repeatability, controlled finishes, and great design freedom. Ideal for complex projects, plastic injection molding is part of our co-development approach for the manufacture of custom plastic parts, from design to industrialization.
A plastic parts manufacturer that meets your challenges
Because every plastic parts manufacturing project is unique, Knauf Industries offers customized support and genuinely seeks to understand the intention behind the design. On this basis, we can then guide you towards the right decisions. In particular, this enables us to respond to clearly identified challenges such as :
- Reduce the weight of your products: Lighter structures and components for lighter, higher-performance products.
- Improving durability: Durable, robust and recyclable materials for longer life.
- Optimizing performance : Thermal insulation, shock absorption, mechanical resistance...
- Reduce your carbon footprint: Eco-design and integration of recycled materials.

The circular economy (3R) at the heart of our processes
To reduce our impact and that of your company on the environment, we propose a circular economy process based on the 3R rule:
- Reduce : Make products and systems lighter, and use recycled materials.
- Reuse: Reusable solutions designed for multiple use cycles.
- Recycling: Recyclable and recycled materials via existing channels and the Knauf Circular® program dedicated to the collection and recovery of end-of-life EPS materials.
Case study: lightweighting in furniture
What better proof of our expertise than a concrete example? Profim, Europe's leading office furniture manufacturer, has collaborated with Knauf Industries to reduce the environmental impact of its products while maintaining their quality and durability. By replacing traditional plywood with recycled expanded polypropylene and optimizing the design, we have reduced part weight by 15%*..
Between production and transport, this represents a carbon footprint reduction of 13% to 40%* compared with standard furniture made from wood or wood-based raw materials. As an added bonus, this has enhanced product recyclability.
The result is a sustainable, competitive solution that meets both consumer expectations and regulatory requirements.
