High Pressure Aluminium and Zinc Die Casting
Aluminium and zinc die casting is a manufacturing method widely used to produce aluminium, zinc and other alloy components by pressing the molten alloy into reusable steel moulds at high pressures. This process results in the production of parts and components with complex geometries, with high precision, and allows the possibility of large-scale production.
Components manufactured with die casting technologies can achieve sharp geometries, smooth or textured surfaces, making them suitable for a wide range of products and applications.
Our high pressure diecasting foundry has an extensive range of machinery to provide flexibility in production. Our machinery can accommodate the manufacture of varying shapes and sizes of castings.
Norfran have extensive experience of manufacturing pressure tight castings, along with experience of cast in components, such as fasteners, pipes, and even electrical components.
Norfran have a continuous investment program, resulting in 13 diecasting cells being fully automated using ABB 6-Axis robots and 2-Axis CNC spraying systems. Our fully automated cells are typically used for longer running high volume production runs. The remaining 4 machines are semi-automated for smaller production runs. In total the facility has 17 aluminium cold chamber die casting machines ranging from 180 Tonne to 800 Tonne, we also have 4 hot chamber zinc die casting machines ranging from 20 Tonne to 200 Tonne. We can cast from 0.002 Kg to 9.00 Kg.
The Advantages of High Pressure Diecasting
High Speed Production – Die casting provides complex shapes within closer tolerances than many other mass production processes. Little or no machining is required and hundreds of thousands of identical castings can be produced before additional tooling is required.
Dimensional Accuracy and Stability – Die casting produces parts that are dimensionally stable and durable, while maintaining close tolerances. Castings are also heat resistant.
Strength and Weight – The die casting process is suited for thin wall parts, which reduce the weight, while maintaining strength. Also, die casting can incorporate multiple components into one casting, eliminating the need for joining or fasteners. This means that the strength is that of the alloy rather than the joining process.
Multiple Finishing Techniques – Die cast parts can be produced with a smooth or textured surface, and they are easily plated or finished with minimum surface preparation.
Simplified Assembly – Die castings provide integral fastening elements, such as bosses and studs. Holes can be cored and made to tap drill sizes, or external threads can be cast.
