• A "multiple-slide" hot chamber die-casting machine has two or more independently movable slides, which carry die blocks and operate within a precision slide guiding system.
• The use of up to four slides is common, and as many as eight slides are possible (six hydraulic and 2 pneumatic)
• Each of the die blocks has one or more cavities and/or cores on its face, which together form the complete cavity and runner profile (into which the molten metal is injected).
• The mating faces of the die blocks are held together by a clamping system.
• Injection of molten metal is made perpendicular to the mating faces of the die blocks, directly on the parting line (“parting line injection”), thereby eliminating the sprue associated with conventional die-casting systems.
  

The advantages of this technology include:

• Complex part geometry produced with high precision; Consistent part quality;
• Excellent part to part conformity
• Quick die changeovers;
• In-die de-gating and automatic separation of parts from runners is possible in many cases;
• Flash-free castings;
• Rapid cycle speeds;
• Low tooling costs;
• Elimination / reduction of secondary operations;
• Savings in material, energy & labor.
