What performance indicators should be considered when purchasing plywood hot press machines
The performance of plywood hot press directly affects production efficiency and product quality. When purchasing, the following key indicators should be carefully considered:
1. Hot pressing temperature range and control accuracy
The hot pressing temperature is the core factor affecting the bonding quality. The equipment should have a stable heating system (such as steam, thermal oil, or electric heating), and the temperature control accuracy should reach ± 1-2 ℃ to ensure uniform curing of the adhesive layer.
2. Pressure regulation ability
The equipment needs to provide sufficient pressure (usually 5-30MPa) and have multi-stage pressure regulation function to adapt to different plywood thicknesses and adhesive characteristics. The hydraulic system should be stable to avoid pressure fluctuations affecting the bonding strength.
3. Size and number of layers of pressure plate
Choose a suitable working area (such as 4 '× 8' or larger) and number of layers (single or multiple layers) according to production needs. Multi layer hot press machines can increase production capacity, but the factory space and investment cost need to be considered.
4. Closing speed and holding time
Quick closure (such as 10-30mm/s) can improve efficiency, while precise pressure holding time control (adjustable range 0-999s) ensures that the adhesive is fully cured, avoiding glue cracking or deformation.
5. Degree of automation
The advanced PLC control system can achieve functions such as automatic feeding, pressing, and unloading, reducing manual intervention and improving production stability and consistency.
6. Energy consumption and environmental performance
Prioritize energy-saving designs (such as waste heat recovery, high-efficiency heating systems) and low-noise, low emission equipment to reduce operating costs and meet environmental requirements.
7. Equipment durability and maintenance convenience
Key components such as hydraulic cylinders and heating plates should be made of wear-resistant and high-temperature resistant materials, and easy to maintain to reduce downtime and maintenance costs.
When purchasing, it is necessary to comprehensively evaluate the above indicators based on production needs, budget, and long-term operating costs to ensure that the equipment is efficient, stable, and economically applicable.
