The Metal Injection Molding (MIM) process.

Often times, excellent and complex design solutions tends to fail commercially – but why? Usually the component is finished with labor-intensive technologies to ensure the right profile and structural design, or maybe it is 3D-printed to avoid the post-finishing. This results in high costs of production and the inability to quickly ramp up large volumes. This is where the technology of Metal Injection Molding (MIM) comes into play as shown in the graph below.

European Production of Metal Injection Molding (MIM).

Sintex distinguishes itself as one of the few companies in Northern Europe employing Metal Injection Molding (MIM), a cutting-edge technique revolutionizing component manufacturing. With the majority of our supply chain operations located within Europe, we ensure efficiency and quality at every step.

MIM technology enables us to produce large quantities of components with exceptional intricacy. Our capabilities extend across various industries, including food processing, thanks to the complex geometries and food-grade surface materials of our products.

What sets us apart is our commitment to tailored solutions for each client. We reject the notion of “one size fits all” and instead offer personalized consultations led by our team of experts. By collaborating closely on component design, we optimize functionality and efficiency, delivering superior results for our clients.

Our customized components vary in detail and weight, accommodating a wide range of specifications. Whether it’s small components at a few grams or larger ones weighing between 30-150 grams, our advanced production facilities can handle it all while maintaining fine tolerances. Unlike our competitors, we excel in producing sizable components, meeting demand with virtually unlimited volume.

MIM Differentiators.

But our differentiation doesn’t stop there. Our components boast unrivaled corrosion resistance, thanks to our development of high-performance alloys. These alloys enhance durability against corrosion, ensuring longevity and reliability in even the harshest environments. At Sintex, our plant only entails stainless steels.

Furthermore, our components are net shape, eliminating the need for post-processing once they leave our production line, hence ensuring high scalability in the continuous furnaces. This streamlined approach not only saves time but also maintains the integrity of the final product.

Combined with our minimal CO2 footprint, these attributes have garnered high praise from our customers and fostered a loyal clientel base. At Sintex, we are committed to innovation, quality, and customer satisfaction, setting the standard for excellence in the industry.

Tooling costs for MIM are very similar to plastic injection molding tools. This means that you often need a large number of parts to balance out the costs

We do not see MIM and 3D printing as competing technologies, but as synergetic technologies. Often you can start production on 3D printing when you are in low volumes, and when volume grows you can transfer to MIM.

In MIM you can produce very complex parts in high volume, but with 3D print you can bring that last level of complexity into the game that is not possible with MIM. Typically, you will find a very smooth surface on a MIM component compared to a 3D printed component. As there are more than ten different 3D printing methods to produce stainless steel samples the properties can vary a lot within the 3D printing world. Feel free to ask our experts at Sintex. They know the details of each 3D printing technology and can advise you on your specific part.
Customer Case.

Metal Injection Molding Transforms Pump Components

Industry: Motors & Pumps

This case study highlights how Sintex revolutionized a ventilation plug for Grundfos pumps using Metal Injection Molding (MIM). By replacing a multi-step cold forging process with a single-shot MIM solution, the plug’s weight was reduced, while corrosion resistance and durability were significantly improved. The redesign also introduced smart features like logo integration, traceability, and a more robust Allen key interface. The resulted in enhanced performance, simplified logistics, reduced water and energy use, and a stronger sustainability profile.
