Pressure die-casting is mostly used when it is necessary to include special geometries for joints, integrated spacers, handles and details for assembling, sophisticated containers, heat sinks with circular fins. Die-cast products can be finished with: - Polishing; - Painting; - Anodization; - Chromate treatment (transparent and gold). As for prototypes and/or little series it is possible to use pressure sand die-casting or with lost wax, prior of producing the final steel die.
