FAQ

Q: What is the key difference between positive pressure and pure negative pressure thermoforming machines?
A: Pure negative pressure thermoforming machines only use vacuum suction to attach sheets to molds, suitable for shallow to medium depth cavity, simple structure, non-porous products. Positive pressure thermoforming machines add 0.5-0.8MPa positive pressure post-shaping after negative pressure pre-forming, suitable for deep cavity, complex structure, perforated products, with more uniform wall thickness and higher product accuracy
Q: What should overseas buyers prioritize when sourcing Chinese positive pressure thermoforming machines?
A: Overseas buyers should first verify the supplier's compliance certifications (such as CE, ISO 9001), then check whether the product's technical parameters (such as forming depth, punching accuracy, production speed) match their actual production needs, and finally evaluate the supplier's after-sales support and global service capabilities.
