Process of Die Casting
SYR works with partners with the latest die casting technology to deliver high quality, on-demand parts. Our typical tolerance accuracy ranges from ±0.0762 mm to ±0.127 mm for aluminium and zinc, depending on customer specifications.
Hot chamber casting, also referred to as gooseneck casting, is the most ubiquitous die casting process. In this process, the injection mechanism’s chamber is submerged in molten metal and the “gooseneck” metal supply structure guides the molten metal into the die cavity.
Cold chamber die casting is commonly employed to reduce machine corrosion. The liquified metal is loaded directly into the injection setup, removing the need to submerge the injection mechanism into the molten metal.

Die Casting Finishing Options
As-Cast
Parts made from zinc and zinc-aluminium have a fair resistance to corrosion as-cast and can be left in this state. On the other hand, magnesium and aluminium require a coating to be corrosion resistant.
Anodising (Type II or Type III)
Aluminium parts are usually anodised. Type II (sulphuric acid) anodising results in a corrosion-resistant oxide finish on the party’s surface. Parts may be anodised in various colours, with black, gold, clear, and red.
Type III (hard) anodising results in a thicker surface layer and produces a wear-resistant layer along with the corrosion resistance obtainable in type II anodising. Anodised parts do not conduct electricity.
Powder Coating
All parts produced from die casting undergo powder coating. In this process, a part is electrostatically sprayed with powdered paint and subsequently baked in an oven.

Overview: What is Die Casting?
For high-volume production of comparatively complex metal parts, die casting is the most suitable manufacturing process. Die cast parts are manufactured using steel moulds that resemble those utilized in injection moulding. Instead of plastics as used in injection moulding, die casting involves metals with low melting points such as zinc and aluminium. Die casting’s popularity is a result of its accuracy, reliability, repeatability, and versatility.
In the die casting process, high pneumatic or hydraulic pressure forces molten metal into a steel mould/die. These moulds/dies can produce highly complex parts with high tolerance repeatedly. The Die casting process makes the most metal parts of all casting processes.
Die casting companies typically specialize in casting either magnesium, zinc or aluminium. Aluminium makes up approximately 80% of die cast parts.
