Back-injection molds for sophisticated decorative components

The development and manufacture of complex back-injection molds have been among our core competencies for decades. With custom-designed mold concepts, we enable the bonding of plastic to textiles, leather, decorative films, and other substrate materials. Our technologies range from traditional back-injection molding to mold solutions with integrated trimming and bending processes. We also produce large-format components that meet high standards for surface quality, dimensional accuracy, and functionality.

Multi-cavity & Multiple Parting Lines

Multi-level tools for efficient mass production

Multi-level molds enable the production of multiple plastic parts in a single injection molding cycle across different parting lines. We develop and manufacture sophisticated mold designs for large-surface-area plastic components and cost-effective mass production. Our range of services includes various mold configurations, such as 1+1, 2+2, and multi-stage solutions. These include complex multi-cavity molds that can be used, for example, to produce four door panels in a single injection molding cycle. Thanks to the intelligent arrangement of the cavities and the optimized mold design, we ensure efficient use of the injection molding machine and reliable mass production.

2K - Injection Molding Tools

Combining different plastics in a single component opens up a wide range of possibilities for integrating functions, material properties, and high-quality surfaces. Using rotary table, transfer, and sliding technologies, we implement complex two-component mold designs for a wide variety of applications. Our expertise ranges from sophisticated two-component headlights to high-quality visible components and technical functional parts. We pay particular attention to material bonding, precisely coordinated tool movements, and reproducible process control.

Polyurethane Overflow (PUR)

Tools for Polyurethane (PUR) Overflow

We develop and manufacture sophisticated tools for flooding large-surface-area plastic components with polyurethane (PUR). This process produces high-quality surfaces with unique visual, tactile, and functional properties. Tooling technology, temperature control, and process stability pose significant challenges, particularly when it comes to large-format components. Drawing on our experience in large-scale tooling, we deliver customized solutions for complex component geometries, consistent surface quality, and cost-effective mass production.

Metal, Plastic, Hybrid Components

Insert - Injection Molding Tools

The integration of metal and functional components into plastic parts places special demands on mold design and process control. With precisely tailored mold designs, we enable the reliable positioning and overmolding of a wide variety of inserts. This results in complex hybrid components that combine the specific properties of different materials and integrate additional functions directly into the plastic component.

Tools for Foam Injection Molding

Through the targeted use of blowing agents, plastic components can be manufactured with reduced weight and a structure optimized for specific applications. Depending on the process, foaming allows for reduced material usage and the targeted modification of mechanical component properties. A particular challenge lies in the precise control of the foaming process. Among other things, our mold technology enables the controlled, precise opening of the mold cavity to specifically influence the formation of the foam structure.

Surface technology

We specialize in special requirements for high-quality surfaces. We offer: technical tool development, classic etch graining, alternatives to conventional etch graining, multi-stage processing steps for sophisticated surface structures and much more.

Gas injection, water injection

injeCtion teChnoloGy

Gas and water injection technology enables the controlled formation of cavities within thick-walled plastic parts. This reduces material usage and part weight while allowing for the creation of functional cavity structures. Our expertise in mold design encompasses gas-injection molding (GIM), water-injection molding (WIM), and specialized secondary and back-pressure processes. Precise mold design and controlled delivery of the injection medium are critical for ensuring reproducible manufacturing processes.

multi-cavity molds

Multi-cavity technology is a decisive factor for efficient series production in the injection molding process. Several identical or different mold cavities are arranged in a single injection mold so that several parts can be produced simultaneously with each shot.

Custom Tool Designs

The right technology for every need

Every plastic component places specific demands on mold design. We combine our experience in injection mold design with innovative manufacturing processes to develop technically sophisticated and cost-effective mold solutions. Whether it’s complex multi-component molds, large-format back-injection molds, or custom solutions—we work closely with our customers to develop the right mold design for reliable mass production.
