- Die Casting In this process, molten metal is injected into a steel mold under high pressure. Die casting is known for producing high-dimensional accuracy and excellent surface finishes, making it ideal for mass production of small to medium-sized components.

In addition to meeting precise specifications, customized stamping parts also contribute to cost savings. When companies choose standard parts, they may often encounter situations where modifications are needed to fit their products, resulting in wasted time and resources. In contrast, investing in customized components from the beginning ensures a perfect fit with existing systems, thus reducing labor costs and minimizing the risk of product failures.

Η τέχνη του χυτοσιδήρου, γνωστή και ως sand casting, είναι μια παραδοσιακή μέθοδος που χρησιμοποιείται εδώ και αιώνες στην επεξεργασία μετάλλων. Αυτή η διαδικασία, που περιλαμβάνει την τεχνητή δημιουργία ενός καλουπιού από άμμο, έχει εξελιχθεί και σήμερα χρησιμοποιείται για την παραγωγή διαφόρων αργυρών αντικειμένων, από κοσμήματα μέχρι μηχανικά μέρη.

Additionally, sanding helps to prepare the surface for other finishing processes, such as painting or seasoning in the case of cookware. A well-sanded surface increases the adhesion of coatings, leading to a more durable finish. Furthermore, sanding can enable the designer or artisan to achieve specific textures and patterns that may enhance the piece's visual appeal.

Investment casting, also known as lost-wax casting, is one of the oldest techniques and is widely favored for its ability to create complex shapes with smooth surfaces. Here, a wax pattern is coated with a ceramic material. Once the ceramic is hardened, the wax is melted away, leaving a cavity that is then filled with molten aluminum. This process allows for high detail and accuracy and is often used in industries where precision is paramount, such as aerospace and medical devices.
