Stamping
Metal stamping is a key mechanical process for finishing die-cast parts. Using automatic presses, we precisely remove burrs and excess material, producing clean components ready for subsequent stages. This process ensures tight dimensional tolerances and high-quality surfaces, enhancing the reliability of the finished part.
At Fonderia Mapelli, we use specially designed equipment tailored for each item, ensuring efficiency, repeatability, and consistency over time, even for large production volumes.
Grinding – Including via Trebi Robotic Cell
Grinding is an essential stage in die-cast finishing, aimed at removing surface imperfections and precisely defining contours. At Fonderia Mapelli, we also use a Trebi robotic cell, which ensures high precision, consistent quality, and reduced cycle times. Automation allows us to handle large production batches with uniform and repeatable results.
Thanks to this advanced technology, we optimize both the aesthetic and functional quality of the part, minimizing subsequent machining and improving overall production efficiency.
Shot Blasting
Shot blasting is a key surface treatment for enhancing the appearance and quality of die-cast components. Through controlled projection of metal grit, we remove oxides, machining residues, and imperfections, achieving clean and uniform surfaces. At Fonderia Mapelli, we use automated systems that ensure high productivity and consistent results across every batch.
This process not only improves the visual appeal of the part but also prepares the surface for subsequent treatments, enhancing the adhesion of paints or protective coatings and increasing the durability of the final product.
Machining
Machining is a strategic step to ensure functionality and compliance with the required tolerances of die-cast components. At Fonderia Mapelli, we carry out operations such as drilling, tapping and facing. Each stage is closely monitored to guarantee consistent quality and adherence to customer specifications.
The integration of machining into our production process allows us to provide a complete service, reducing lead times and delivering components ready for assembly or installation.
Tumbling
Tumbling is a finishing treatment designed to improve the surface appearance of die-cast components by removing sharp edges, residual burrs, and minor imperfections. At Fonderia Mapelli, we use rotary tumblers with specific abrasive media, selected according to the material and geometry of each part. This process ensures smoother and more homogeneous surfaces, improving handling, aesthetics, and preparation for subsequent treatments.
Tumbling is particularly suitable for components intended for sectors where refined finishes and precise aesthetic tolerances are required, ensuring consistent quality and repeatability.
Painting
Painting is a final stage that enhances the value of die-cast components both aesthetically and functionally. At Fonderia Mapelli, we offer various painting solutions, including epoxy powders and liquid coatings, tailored to customer requirements and component applications.
This treatment improves corrosion resistance, protects against environmental stresses, and gives the part a uniform, professional finish. Each cycle is carried out with strict attention to quality, ensuring optimal adhesion, long-lasting performance, and compliance with the required specifications.
Heat Treatments
Heat treatments are essential to modify the mechanical properties of die-cast components, improving their strength, hardness, and dimensional stability. At Fonderia Mapelli, we provide different types of treatments, such as stabilization, solution heat treatment, and aging, depending on customer specifications and the final application of the part.
Each thermal cycle is managed with precision and rigor, ensuring uniform results and complete traceability. The integration of these processes into our production flow allows us to deliver components that are more durable, reliable, and capable of performing under demanding operating conditions.
Vibratory Finishing
Vibratory finishing is a surface treatment that uses vibratory motion combined with abrasive media to remove burrs, sharp edges, and surface imperfections from die-cast parts. At Fonderia Mapelli, we employ this technology to achieve smoother, more homogeneous surfaces, ready for subsequent treatments such as painting or assembly.
The process is ideal for enhancing the appearance and handling of components, ensuring uniform results even across large production batches. Continuous monitoring guarantees repeatable quality and compliance with customer technical specifications.
