HYDRAULIC PRESS FOR MOLD AND DIE ADJUSTMENT WITH LOWER TABLE EJECTION AND UPPER TABLE TILTING

The ML-300E/NC hydraulic press belongs to the M/NC series and is custom-designed for the adjustment of molds and dies, featuring a movable lower table and a tilting upper table.

It includes chrome-plated and rectified cylindrical columns with protective bellows, 200 mm in diameter, made from C45E steel, specifically manufactured to maintain a low friction and wear coefficient.

It uses an optimized hydraulic system with a pressure below 290 Bar, ensuring prolonged durability and reliability.

It meets and satisfies all essential safety and health requirements according to CE regulations.

MORE INFORMATION

STRUCTURE AND TABLES

  • Structure made from oxy-cut steel, divided into four electro-welded and machined monoblocks.
  • Movable lower table and tilting upper table, both machined with T-slot fixation grooves.
  • Lower table designed to support up to 50 TN in displacement, supported by bronze guides with graphite load and mechanical positioning centers for precise table positioning.
  • Upper table equipped with hydraulic safety pins to prevent falling, and tilting counter-table at 110°, designed to support molds up to 35 TN during tilting, with disengagement and ramp parking at 140°.

CYLINDER AND HYDRAULIC GROUP

  • Single-acting cylinders with lapped sleeves, chrome-plated pistons, and anti-wear guides.
  • 400-liter hydraulic group with a silent 1-speed Denison pump, automatic disconnection of the fast approach pre-filling speed, and equipped with a decompression system for working speed.
  • Hydraulic group cooling system with an independent air-oil radiator unit.
  • All M/NC series hydraulic presses include a lateral pressure switch allowing adjustment of the most suitable pressure setting for each type of work.
  • Glycerin manometer with tonnage reading.

ELECTRICAL INSTALLATION AND SAFETY

  • Electrical installation for manual and automatic operation of the main cylinder advance, low-voltage operation via two-hand pushbutton and gravity-drop pushbutton.
  • Includes a SIEMENS safety PLC model SIMATIC S7 1200 and a 7” touchscreen model MTP-700 located at the top of the electric pedal. Allows programming of semi-automatic and automatic operating modes, power, travel, and dwell time of the upper cylinder. Capable of storing 300 recipes, each with programmable values.
  • Electronic safety system for the upper table pins and mechanical and electronic positioning of the removable lower table.
  • Features anti-fall safety system with rack and trigger for automatic closure in case of hydraulic pressure failure or electrical system malfunction.
  • Level IV photoelectric barriers installed at the front and rear, along with lateral protections with openings and safety microswitches.
