Products & services
Product Development Support
We bring your product idea to life through injection-molding expertise and support you from the first sketch all the way to a ready-for-production solution. True to our motto, “Sleeves up – we simply make it happen,” we take a holistic approach to development: prototypes, pilot production, and series production are seamlessly integrated within our process. Our technical sales team acts as your primary point of contact. Even before an order is placed, we review your requirements, assess the component for injection-molding feasibility, and support you in optimizing the design for subsequent series production. Using injection-molding simulations (CADmould), in-depth design refinement, and transparent cost calculations, we establish a solid basis for informed, economically sound decisions. A comprehensive DFM report (“Design for Manufacturing”) helps identify potential challenges at an early stage and resolve them in a targeted manner. Building on this foundation, our design department develops the appropriate toolmaking strategy. All relevant requirements from the involved specialist departments are incorporated into the tool concept before final approval. We work with high-performance CAD systems such as Autodesk PowerShape and Creo, and rely on renowned European manufacturers for mold bases and hot runner systems. Through the close integration of technical sales, simulation, design, and subsequent industrialization, we deliver solutions that are not only technically sound but can also be manufactured cost-effectively – ensuring the long-term success of your projects.
project management
Our customers develop the ideas and products of tomorrow – and to do so, they need a project team that listens, thinks ahead and stands reliably by their side. This is exactly where our project management comes in. At Wartenfelser, we accompany your project from the first idea to the finished plastic component. We bring all steps together under one roof, coordinate the involved departments and create a structured, transparent workflow. For you, this means: one responsible point of contact, clear communication and a process that moves forward without detours. Whether scheduling, coordinating with development and toolmaking, or preparing for subsequent series production – we keep the overall project in view and ensure that every element works seamlessly together. The result is a process that remains manageable for you and significantly simplifies the path from concept to finished product.
mold making
True to our motto “We simply do it… ourselves,” Wartenfelser operates its own in-house toolmaking department. It forms a key component of our service promise, enabling us to react, adapt, and further develop precisely when your project requires it. Within our in-house moldmaking division—comprising maintenance and new tool manufacturing—we create the foundation for smooth and stable production processes. Close coordination with development, project management, and injection molding ensures short communication paths, clear decisions, and the direct implementation of your requirements. For you, this means fast availability, reliable workflows, and tools that are perfectly tailored to your components and production volumes. In this way, we establish the basis for consistent quality throughout the entire lifecycle of your products.
injection molding
Injection Moulding – A Holistic Approach At Wartenfelser, we combine modern manufacturing technology with responsible resource management and a clear focus on economically efficient processes. Our 600 kWp photovoltaic system supplies a large part of our production with self-generated, renewable energy. Supported by digital systems across all areas of the company, this creates an environment in which stable series production and sustainable operations are seamlessly united. Efficient injection moulding is built on the expertise of experienced application engineers and a high degree of automation, enabling reliable processes and short throughput times. Continuous improvement and targeted employee development ensure a manufacturing environment that remains powerful and competitive in the long term. At our Hemhofen site, more than 60 modern injection moulding machines are available – ranging from compact units with 25 tonnes of clamping force to high-performance systems with 550 tonnes. This flexible machine park enables the economical production of a wide variety of part geometries and volumes and forms the backbone of our series manufacturing. Our production is fully digitally networked – from the ARBURG host computer system to structured maintenance and service processes, all the way to an intelligently integrated production planning system. Version-controlled documentation and clear data structures ensure transparency and complete traceability for every project. In the area of sustainability, we consistently rely on resource-efficient part design, extensive use of hot-runner systems, heat recovery for building heating and service water, as well as reusable shuttle packaging. The result is injection moulding that combines technological strength, digital processes and sustainable thinking – ensuring your products are reliably brought into series production.
Automation
Even the most dedicated employee eventually needs to call it a day – but our “Robbis” don’t. They work reliably around the clock and are therefore an essential part of our production operations. With our own automation department, we ensure stable processes, high system availability, and consistently superior component quality. Already during the initial customer inquiry, we analyze the potential for automated manufacturing and define the possible level of automation with full transparency. Based on this, we create a clear and structured quotation that precisely outlines the automation potential for each project. When needed, we produce prototypes using 3D printing. For industrialization, we rely on high-quality robotics, standardized modular components, and a high degree of in-house production depth in our automation solutions. Validation takes place in parallel with component qualification, ensuring that both processes align seamlessly. Where necessary, automated optical and mechanical inspection systems enable 100% inspection of every single part – meeting even the most demanding requirements, including 0-ppm targets. The result is automation that is technically sophisticated, economically efficient, and precisely tailored to the needs of each project.
Plastic parts with added value
As a long-standing system supplier, we don’t just “roll up our sleeves” when it comes to injection molding. We also take full responsibility for all upstream and downstream value-adding processes, ensuring that you receive your product from a single source – cleanly coordinated, expertly monitored, and reliably executed. A complementary supplier management system ensures that we can involve the right specialists for every specific requirement, without any effort on your part. For surface finishing, we offer a wide range of processes: from pad printing, electroplating, metallization, and flocking to laser marking and coating. This ensures that every component receives exactly the visual and functional properties required for its intended application. We also take responsibility in the area of assembly. Our in-house assembly department produces complex small series, including integrated optical inspections. In addition, products are professionally assembled by our inclusion group on-site or further processed through long-standing cooperation partners as part of an extended workbench. Depending on the requirements, semi-automated workflows or even fully integrated automation solutions can be implemented directly within the injection molding process. The result is a comprehensive package that goes far beyond injection molding alone – a holistic solution that streamlines processes, ensures quality, and significantly reduces workload throughout your product development cycle.
