Components of Pressing Machine

0 2,456

Regardless of fabric, type of garment or the machinery and equipment employed, the majority of pressing operations have the same components.

Irons are made primarily of plastic and metal (aluminum and steel). The materials often come to the factory in the form of plastic resins, aluminum ingots, and steel sheets. The metal is used to make the sole plate, thermostat, and other internal mechanisms. Plastics are used to make the exterior and handle, as well as the water tank.

Components of Pressing


The purpose of using pressurized steam is to relax the fiber structure of the fabric and make it pliable enough to be molded by manipulation and pressure. Steam itself is an odorless, invisible gas consisting of vaporized water, and its white cloudy appearance is caused by minute water droplets interspersed in the vapor.

In factories, steam is generated by boilers fired by electricity or fossil fuels such as coal, gas or oil. Depending on the number of pressing workstation in the factory, steam can be distributed from central boiler room by a small boiler located close to the workstation.
There are also independent pressing units which have a built-in boiler for generating their own steam.Steam is a flexible, adaptable and efficient component of pressing.Some of its outstanding features are:

  • It has very high heat content.
  • Its heat is generated at a constant temperature.
  • It can be easily distributed and controlled.
  • Water is relatively cheap and plentiful.Steam has been used throughout the centuries for pressing and it is still the best medium for this purpose.


After steaming, the manual or mechanical pressure is used to change the geometric fiber lay of the area is pressed. A simple example of this change is the pressing open of a regular seam. This structural change is typical of the majority of pressing operations.


Following the application of steam and pressure, the area which has undergone these processes has to be dried and cooled in order that the fabric can revert to its natural moisture content and stable condition. The drying process is usually performed by a central vacuum pump which is connected to pressing units, or by pumps built into ma machine itself. The vacuum action removes the residual moisture from the material while it is lying on the pressing area.


The length of time to which a component or garment ifs subjected to steaming, pressure, and drying is a combined function of steam temperature, garment construction and the physical properties of the fabric being pressed. Whilst there are no fixed rules for the duration of these components, the experience is a good teacher. Accurate control of the four components of pressing is essential to the maintenance of uniform quality. This is one of the main reasons why modern pressing machines can be programmed for the duration, operating conditions and sequence of all of the elements within a specific pressing operation.
