Automatic Steel Door Hot Press Machine

Through-feed hot press for bonding up to 15 layers of metal sheets for steel door panel production

Automatic steel door hot press machine achieves the thermal pressing and bonding of door panels through the circulation of heat-conducting media such as hot water or thermal oil. The hot pressing temperature can reach 80-120℃ to ensure a durable and reliable bonding effect. It features a fully automated operation process, allowing one person to operate multiple machines simultaneously. It can handle bonding layers ranging from 8 to 15, and customization of gluing layers and dimensions is also available according to specific requirements.

Production Process

Details

2. Feeding Conveyor
  Servo motors are used to ensure smooth operation, anti-interference, and multiple control modes.
  Rollers made of high-quality materials (rubber, silicone, polyurethane) offer noise reduction, strong load-bearing capacity, smooth operation, and wear resistance.
  The body adopts pull welding process to further improve the stability of the body connections and increase the service life.
2. Feeding Lift
  The machine body is welded from 7mm thick steel plate, the platform is processed by gantry milling, and the body undergoes anti-corrosion and rust removal treatment, with the entire body sprayed with anti-rust paint.
  Automatic lifting: the door panels are pushed using a belt conveyor, without the need for manual operation.
2. Hot Press
  Q235 heating platens are used for good pressure-bearing performance, more uniform heating, and longer service life.
  A new integrated hydraulic system is used, with an accumulator control system.
  Bonding multiple layers of large flat steel plates, eliminating concerns about warping and deformation during door lamination.
  A forced air cooling system reduces the working temperature of the hydraulic system.
  Multiple heating medium configurations are available.
2. Discharge Lift
  The machine body is welded from 7mm thick steel plate, the platform is processed by gantry milling, and the body undergoes anti-corrosion and rust removal treatment.
  Automatic lifting: the door panels are received using a belt conveyor, without the need for manual operation.
  Functions for material retrieval use belt conveyor and door-holding retrieval methods.
2. Edge Pressing Machine
  The machine body adopts pull welding process to further improve the stability of the body connections and increase the service life.
  An integrated cylinder helps to ensure no oil leakage during prolonged use.
2. Electrical Control System
  The entire metal door press machine is controlled by PLC system, optional in Delta/Siemens/Mitsubishi, etc.
