Ordinary low-pressure casting moulds are only suitable for conventional aluminum alloy production. When facing special alloys such as magnesium alloy and zinc alloy, molten metal will produce strong electrochemical corrosion and chemical adhesion on the mould cavity surface, resulting in rapid pitting, peeling and precision failure. Special alloy castings have higher chemical activity, putting forward higher anti-corrosion requirements for moulds. Xinfeng Machinery develops exclusive anti-corrosion mould schemes for special alloy production scenarios.
Anti-corrosion material upgrading is the core of special mould design. Ordinary H13 steel has poor resistance to magnesium and zinc alloy corrosion. Upgraded anti-corrosion hot-work steel can effectively resist electrochemical corrosion of high-temperature alloy liquid and avoid rapid cavity damage.
Composite protective coating strengthens surface anti-corrosion performance. On the basis of conventional nitriding treatment, adding high-temperature anti-corrosion coating forms a double protective layer, isolating the contact between molten alloy and mould steel, and solving adhesion and corrosion problems fundamentally.
Process and structural coordination maintain long-term anti-corrosion effect. Matching special low-corrosion release agents and smooth cavity structure can reduce residual alloy adhesion, avoid local concentrated corrosion, and simplify daily anti-corrosion maintenance work.
