This encyclopedia covers the definition, technical standards, product classification, application scenarios, market trends and mainstream suppliers of the industry, helping readers quickly establish a systematic understanding of the industry.

Industry Core Definition
According to ISO 12100 safety standards for packaging machinery, a four-station positive-negative pressure thermoforming machine refers to a precision industrial equipment that uses independent parallel stations to complete thermoplastic sheet heating, negative pressure pre-forming, positive pressure supplementary forming, high-precision punching, cutting and automatic stacking. Its core difference from traditional 3-station thermoforming machines lies in the independent punching station, which can complete hole processing without secondary processing, greatly improving production efficiency.

The core attributes of the industry are as follows:
1. Technical attribute: Precision servo drive, composite positive-negative pressure forming, CNC intelligent control
2. Application attribute: Industrial supporting for packaging manufacturing, covering multiple downstream industries
3. Market attribute: Globalized supply, high growth driven by packaging upgrading and degradable material popularization.
