Thermoforming packaging machine


What is thermoforming?

Thermoforming (from wikipedia.org) is a manufacturing process where a plastic sheet is heated to a pliable forming temperature, formed to a specific shape in a mold, and trimmed to create a usable product. The sheet, or “film” when referring to thinner gauges and certain material types, is heated in an oven to a high-enough temperature that permits it to be stretched into or onto a mold and cooled to a finished shape. Its simplified version is vacuum forming.

Thermoforming packaging machine

Thermoforming packaging machine is also as known as roll stock packaging machine, stretch film vacuum packaging machine, or in short : thermoformers.
Horizontal automatic packing machines characterised by package formation within the machine using two film coils (forming/under film, sealing/upper film) normally made of different material.
Depending on the material used, packages can be flexible or rigid. This type of machine is aimed both at food and non food markets.

    • The forming chamber adopts 4-axis linear bearings vertical stable lifting system. The bearing uses linear bearings produced by German Igus to ensure that the forming will not be misaligned and high precision. The forming chamber adopts 4-way air pumping system, which has fast forming efficiency and good stability.
    • Vacuum sealing chamber adopts 4-axis linear bearing vertical stable lifting system, German Igus linear bearing. Sealing heating plate owns 8 Airtac cylinders and positioner, which ensures vertical sealing of heating plate, smooth sealing, clear pressure pattern, no skew, perfect sealing effect, high packaging efficiency and no leakage after sterilization.air cylinder lifting system
    • Forming chamber, vacuum sealing chamber and cylinder lifting mechanism adopt the principle of triangular lever, with self-locking function which ensures stable lifting.
