Die Casting Services
Die casting forms metal parts by injecting molten alloy into a steel mould under high pressure. It delivers strong, dimensionally stable components with great surface finish and tight tolerances. Ideal for medium to high-volume production, die casting is widely used in automotive, electronics, hardware, and industrial applications where accuracy and durability matter.
High-Pressure Die Casting (HPDC)
High-pressure die casting injects molten aluminium, zinc, or magnesium alloys into a hardened steel mould at high speed and pressure. It enables thin-walled parts, sharp details, and excellent surface finish. Standard tolerances are typically ±0.1-0.2 mm, with precision cavities achieving ±0.05-0.1 mm. HPDC is ideal for housings, brackets, enclosures, automotive components, and medium-to-high-volume production runs.
Low-Pressure Die Casting (LPDC)
Low-pressure die casting uses controlled pressure to fill the mould, resulting in fewer porosity defects and improved mechanical strength. Standard tolerances are ±0.2-0.4 mm, with tighter features around ±0.1-0.2 mm. LPDC is commonly used for structural components, wheels, chassis parts, and parts requiring improved integrity over HPDC.
Gravity Die Casting (Permanent Casting)
Gravity die casting fills the mould using gravity alone, producing parts with stable dimensions and reduced porosity compared to sand casting. Standard tolerances are ±0.25-0.5 mm, with precision areas reaching ±0.15-0.25 mm. This method is suited to thicker-walled components, housings, hydraulic parts, and medium-volume production where durability is required.
