Hot Press Machines: The Beginner’s Guide

What is a hot pressing machine?

A hot press is a device that preheats two parts coated with flux and tin to a temperature sufficient to melt and flow the solder.

After curing, a permanent electrical and mechanical connection is formed between the parts and the weld. The heating speed can be selected based on specific product requirements.

Titanium alloy indenter ensures consistent temperature, rapid temperature rise and long-lasting performance. It is specially designed with a horizontally adjustable feature to ensure even distribution of pressure across components.

Temperature control is digitally managed, providing clear and accurate readings. Additionally, the device is equipped with a digital pressure gauge that allows you to set a specific pressure range.

Hot press working principle

The Principle of Pulse Heating: The surface design of the welding head is specially crafted to minimize resistance, allowing current to flow through the section with the least resistance. By alternately changing voltage and adjusting current levels, the welding head can quickly generate heat.

Pulse current refers to the on-off frequency ratio of the current. The higher the pulse ratio, the greater the current output, resulting in a faster temperature rise in the welding joint.

Hot press features

  • Temperature control is precise using pulse heating technology and the temperature sampling frequency is 0.1 seconds.
  • The device offers a variety of working modes, including a single working platform, rotating working platform, left-right moving platform and more.
  • The temperature rise can be controlled in several stages.
  • A real-time temperature curve display is available.
  • The device has a silicone strip indexing mechanism.
  • CCD vision system provides accurate alignment.
  • Various programs can be pre-stored.
  • The device has a touch-operated interface and program password protection.

Hot press rating

The types of hot press include constant temperature hot press, pulse hot press, double station hot press, double indenter pulse hot press, desktop hot press, etc.

Hot press application

Hot press can be used in various industries including:

  • Manufacture of cell phones;
  • Manufacture of touch screens;
  • Computer manufacturing;
  • Printer manufacturing;
  • Manufacture of membrane switches and much more.

What is the difference between hot pressing and cold pressing?

We are aware that hot and cold pressing techniques are widely used and have relatively good efficiency.

Do you understand the difference between hot pressing and cold pressing?

Allow me to explain the distinction between the two.

  • A hot press is a device that pre-coats two parts with tin flux and heats them to a temperature sufficient to melt and flow the solder, forming a permanent electrical and mechanical connection between the parts and the solder. Heating speed may vary depending on the product.
  • Hot press is commonly used in furniture manufacturing, wooden door factories and secondary processing and veneering of wood-based panels. It is a crucial machine in woodworking machinery and is mainly used for hot pressing and gluing surface materials of furniture panels, building partitions, wooden doors and fire doors.
  • Cold press, also known as cold dryer compressor, is essentially a refrigeration unit with a compressor as the main body. Its function is to cool. This refrigeration unit is called a cold press. The amount of water vapor in compressed air depends on the temperature of the compressed air.
  • Cold pressing is used in furniture production and in the processing and production of glued pressed wooden parts, such as speakers, in the wood industry, decoration, plastics, flat plywood, plywood, chipboard and veneer. With high production efficiency and excellent quality, it is suitable for producing wooden product components in furniture production units and other industries.
  • Both cold and hot pressing are used to flatten, glue, veneer and press boards. As the name suggests, cold pressing only presses at normal temperature, while hot pressing heats the plate to a temperature of up to 300 degrees, resulting in greater flatness of the plate surface.
