Product description

Performance characteristics:

A: The machine adopts the "triple pressure" molding process to ensure the smooth exhaust of the powder product molding and the uniformity of the product density.

B: The machine has two pressing forms: asynchronous two-way pressing (floating pressing) and synchronous two-way pressing, which can be adapted to press forming of radially asymmetric parts and radially symmetric parts respectively, so as to reasonably arrange the neutral layer, reduce sintering deformation, and improve Pass rate.

C: The machine has three demolding methods: "top demoulding", "pull-down protective demoulding", "micro-return, protective demoulding" to adapt to various performance materials, especially those with strong resilience. Come out of the cavity.

D: The combination of electric, hydraulic and machine positioning is adopted for the product powdering height, demoulding position and pressing height, which can realize the two pressing methods of "fixed-range control, pressure protection" and "pressure control, position protection" to ensure product batches Consistency of production, repeat positioning accuracy can reach ≤±0.03mm.

E: The machine is equipped with a core rod drive mechanism to prevent internal cracks when the product is demolded. When demolding, the core rod does not move, the female mold is pulled down, and the product is completely released from the female mold cavity, and finally the core rod is down.

F: The hydraulic system adopts integrated block oil circuit, oil precision filtering system and water cooling device. The flange structure is preferred, and the hose connection ensures stable and reliable operation, small impact and less leakage. The use of high and low pressure combined pumps for oil supply reduces power consumption.

G: The electrical system adopts imported PLC, time relay control, with adjustment, semi-automatic and fully automatic operation modes.
