These commercial heat press machines are used to smooth the surface of pulp trays of various sizes through high pressure and high heat conditions. The pulp tray shaping machine is heated electrically to reach a hot press die of about 200°C. The surface of the pulp trays is then made smooth by the downward pressure of its pressurizing cylinder. The hot press is very suitable for processing various pulp trays, especially for processing various industrial pulp trays, such as wine trays, precision instrument trays, industrial mold trays, fruit trays, coffee cup trays, egg trays, etc.
Why use a heat press machine to process pulp trays?
In the pulp tray production line, the heat press is an essential piece of equipment. Using a heat press to smooth the surface of pulp trays can improve their appearance, increase strength and durability, improve printing, and increase production efficiency. These benefits help increase the marketability of pulp trays and meet consumer demand for high-quality and attractive packaging products.
- Improve the appearance quality: The heat press can make the surface of the pulp egg tray flat and smooth, eliminating uneven texture and surface defects. This makes the egg tray more attractive in appearance and meets the market demand and consumers’ aesthetic standards.
- Increased strength and durability: The surface of the pulp egg tray is stronger after the hot pressing treatment, which can improve its compressive strength and durability. This ensures that the egg tray is less likely to be deformed or damaged during transportation and storage, protecting the safety of the eggs.
- Improved printing: The flat surface of the heat press treatment helps to improve the printing quality of the egg tray. If the egg tray needs to be personalized or logo printed, the flat surface ensures the clarity and quality of the pattern and text, increasing the attractiveness and recognizability of the product.
- Increased productivity: A heat press can process pulp egg trays quickly and easily. By using a heat press for surface leveling, you can speed up production, increase productivity and meet mass production needs.

How to operate the pulp tray hot press machine?
- Confirm the completion of the inspection before starting the machine, you can carry out the production operation.
- Turn the “manual/automatic” rotary switch on the operation panel to the automatic position.
- Take the semi-finished products that match the mold on the equipment and put them on the mold flatly, press the two start switches with both hands at the same time.
- When the upper table and the lower table of the equipment close the mold, release the start button switch to prepare the next product and wait for the upper and lower molds to separate.
- Wait for the upper and lower die separation will be shaped after the product is out, and check whether the product meets quality standards.
- Check the completion of the stacking of finished products to continue the next product shaping work.
- The operator must wear gloves and sleeves when working, to avoid burns.
- One person is strictly prohibited to start the machine more than one person to pick up and put the product, so as not to crush it.
- Pay close attention to the operation of the equipment when working, such as abnormalities, immediately press the emergency stop switch turn off the power, and promptly report to the shift supervisor and related technical personnel.
