Aluminium extrusion mould making is the process of creating a mould or die that is used in the extrusion of aluminium profiles. The mould is typically made from steel or other durable materials and is designed to shape the molten aluminium into the desired profile. The process of aluminium extrusion involves heating a billet of aluminium to a specific temperature and then forcing it through the mould using a hydraulic press. The molten aluminium takes on the shape of the mould as it passes through, and once it cools and solidifies, it forms a solid aluminium profile. The first step in aluminium extrusion mould making is designing the mould. This involves determining the desired shape and dimensions of the aluminium profile and creating a corresponding mould design. The design may be created using computer-aided design (CAD) software and may include multiple cavities to produce multiple profiles simultaneously. Once the mould design is finalized, it is then manufactured using precision machining techniques. This may involve CNC milling, turning, and grinding to create the necessary features and dimensions of the mould. The mould is typically made from steel or other high-strength materials to withstand the high pressures and temperatures involved in the extrusion process. After the mould is manufactured, it is carefully inspected to ensure it meets the required specifications. Any necessary adjustments or modifications may be made at this stage to ensure the mould will produce the desired aluminium profiles.
