Two-platen injection molding machine

With the development of material technology, there is a growing trend of plastic components becoming larger and heavier. As a result, the clamping force of injection molding machines chosen by plastic injection manufacturers is also increasing. Compared to the commonly chosen three-plate injection molding machines (crankshaft clamping mechanism) in domestic manufacturers, the two-plate injection molding machines (direct-pressure clamping mechanism) utilize four high-pressure clamping hydraulic cylinders to simultaneously pull the columns, applying pressure and holding the mold. The opening hydraulic cylinder requires less opening force, typically half of the opening force of a three-plate injection molding machine with the same tonnage. The hydraulic cylinders with lower opening force are easier to process and maintain during actual usage, resulting in a longer service life and reduced susceptibility to damage.
  • Specification

? Compact body design, occupying a small footprint.

? Large opening stroke, suitable for deep cavity molds.

? Better mold clamping balance.

? More energy-efficient than three-plate injection molding machines of the same tonnage.

? Low operating cost, as it features a non-tie-bar structure that eliminates the need for lubrication, saving a significant amount of lubricating oil. It also requires simple maintenance and upkeep.

? No mold adjustment is required, making it easy to operate.

? Superior mold capacity over a wide range.Mold capacity is a critical technical parameter in the locking mechanism of an injection molding machine, and it directly affects the practical range of the machine. A large mold capacity enables the machine to accommodate the production needs of both thin and thick molds.

? When a two-plate injection molding machine generates locking force, the tension section (length under tension) of the tie bar is relatively short. The thickness of the mold corresponds to the length of the tension section. Therefore, the deformation generated by the tie bar with such a short tension section is minimal.
