Conclusion The HX-7585 Positive and Negative Pressure Plastic Thermoforming Machine proved to be an effective solution for PP food container production in Russia. By addressing energy efficiency, mold adjustment complexity, and production stability, the machine enabled the client to maintain consistent product quality while achieving high-speed, low-maintenance operation. This case demonstrates the suitability of three-station automated thermoforming systems for manufacturers aiming to optimize workflow and ensure reliability in demanding food packaging applications.

Positive and negative vacuum thermoforming machines differ significantly in working principles and application fields from negative vacuum thermoforming machines. Positive-negative vacuum thermoforming machines employ a bidirectional pressure molding process with upper and lower pressures, making them suitable for processing products with deep cavities and complex geometric shapes. This process ensures uniform wall thickness distribution, guarantees product molding quality, and offers high production efficiency. In terms of material applicability, the positive-negative vacuum technology is particularly suitable for manufacturing products with high molding precision requirements, such as highly transparent packaging boxes, medical device packaging, and biodegradable materials. In contrast, negative-pressure thermoforming machines are primarily suitable for applications involving simple structures, shallow cavities, and small-batch production, offering the advantage of lower equipment investment costs. However, it should be noted that the mold manufacturing cost for positive/negative pressure thermoforming machines is typically several times higher than that of negative pressure thermoforming machines, reflecting the investment disparity arising from their superior precision forming capabilities and broader process adaptability.

Late last year, delegates from more than 170 countries held a week-long meeting in Busan, South Korea, to discuss binding measures to control global plastic pollution.  But in the end, the fifth round of negotiations on the United Nations Plastics Convention did not reach any agreement. The representatives of some countries, including the United Kingdom, believe that the negotiations should continue, but the representatives of some countries think that the current way is somewhat "Impracticable."  Our company has come up with a solution to this problem; corn and bamboo instead of PVC or PET such as plastic can make a variety of beautiful and healthy biodegradable environmental food and fruit boxes and so on. The success of this scheme will open the market in Europe for all kinds of biodegradable and environmentally-friendly hamburger boxes, and the future is optimistic. Contribute to the sustainable development of the earth.

1. Upgrading of heating method: Replace the traditional integral heating tube with partitioned independent temperature-controlled heating plates, and divide 3-5 temperature control areas according to the different heating requirements of the plastic mold (such as edge and center areas). Each area is equipped with independent thermocouple sensors and PID temperature controller, the temperature control accuracy is improved from ±5℃ to ±1℃, avoiding material deformation caused by local overheating or incomplete forming caused by overcooling.2. Energy-saving transformation: Install nano insulation cotton + reflective film on the outside of the heating plate to reduce heat loss; at the same time, add an "intermittent heating trigger mechanism". When the material temperature reaches the set value, the heating power is automatically reduced to 30% for insulation, which is compared with traditional heating methods. Energy saving by 25%-30%.
