HLH offer pressure die casting services which is great for manufacturing higher volumes of metal parts in aluminium, zinc or magnesium. HLH manufactures high quality die cast tools, offer precision die casting and post process machining and finishing options.
How It Works – Similar to injection moulding but for metals, a mould tool is first manufactured by HLH’s highly skilled toolmakers and engineers. This is then installed on a die casting press and molten metal is injected under pressure into the tool cavity. The parts can then be finished in a range of ways including powder coating and anodising.
Also known as gooseneck casting, hot chamber is the most popular die casting process. A chamber of the injection mechanism is immersed in molten metal and a "gooseneck" metal feed system brings the metal into the die cavity.
Cold chamber die casting is often used to minimize machine corrosion. The molten metal is ladled into the injection system directly, eliminating the need for the injection mechanism to be immersed in the molten metal.
