HOW MANY TYPES OF INJECTION MOLDING MACHINES ARE AVAILABLE IN THE WORLD?
In driving manner: Hydraulic, all electrical, hybrid type injection molding machine.
In opening and closing direction of mold clamping unit: Horizontal, vertical. Most of the machines are horizontal type. Vertical type is suitable for small insertion products.
In material processed:Thermoplastic material, thermosetting material (thermosetting), powder injection (metal, ceramic, alloy). Presently, most of the units are for thermoplastic materials.
In Hydraulic loop: Single loop, multiple loop (dual or triple) injection machines. Most of the units presently are single loop injection molding machines.
In hydraulic circuit control: Open loop, Close loop injection machines. Injection molding machines are generally of open loop type, but the close loop type is growing for machine stability.
In mold clamping structure: Toggle type, hydraulic, hydra- mech (two-plate type). In these 3 types, each has its own advantages and shortcomings. Presently toggle type is prevailing.
In Injection Mechanism: Single color, (one set injection), multi-color (multi-component injection). Most of the existing units are single color unit.
