Hot Press Machines: The Guide for Beginners

What is a hot press machine?

The hot press is a device that heats two parts coated with flux and tin in advance to a temperature sufficient enough to melt and flow the solder.

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

The titanium alloy indenter ensures consistent temperature, rapid temperature increase, and long-lasting performance. It is specially designed with a horizontally adjustable feature to ensure even pressure distribution on the components.

The temperature control is digitally managed, providing clear and precise readings. Additionally, the device is equipped with a digital pressure gauge that allows for the setting of a specific pressure range.

Working principle of hot press

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

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

Characteristics of hot press

• The temperature control is precise with the use of 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, rotary working platform, left-right mobile platform, and more.
• The temperature rise can be controlled in multiple stages.
• A real-time temperature curve display is available.
• The device features a silicone tape indexing mechanism.
• The CCD vision system provides accurate alignment.
• Multiple programs can be pre-stored.
• The device has a touch-operated interface and program password protection.

Classification of hot press

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.

Application of hot press

The hot press can be used in various industries including:

• Mobile phone manufacturing;
• Touch screen manufacturing;
• Computer manufacturing;
• Printer manufacturing;
• Membrane switch manufacturing, and more.

What is the difference between hot press and cold press?

We are aware that hot press and cold press techniques are widely used and boast relatively good efficiency.

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

Allow me to explain the distinction between the two.

• Hot press is a device that pre-coats two parts with flux tin 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. The heating speed can 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 bonding the surface materials of furniture panels, building partitions, wooden doors, and fire doors.
• Cold press, also known as a cold dryer compressor, is essentially a refrigeration unit with a compressor as its main body. Its function is to cool. This refrigeration unit is referred to as a cold press. The amount of water vapor in compressed air is dependent on the temperature of compressed air.
• Cold press is utilized in the production of furniture and the processing and production of wooden glued pressing parts, such as speakers, in the wood industry, decoration, plastics, plane plywood, plywood, particleboard, and veneer. With high production efficiency and excellent quality, it is suitable for the production of wood product components in furniture production units and other industries.
• Both cold press and hot press are utilized for flattening, bonding, veneering, and pressing plates. As the name suggests, cold press only presses at normal temperature, while hot press heats the plate to a temperature of up to 300 degrees, resulting in a higher flatness of the plate surface.
