Car Air Ducts Pipe Blow Moulding Machine Advantages:

Advantages of 3D blowing technology

Compared with the traditional blow molding technology, the advantages of 3D technology:

To improve the quality of products by avoiding extrusion joint:

●The wall thickness is well-distributed

●No strength weakened, because it can avoid raw material accumulation and notch.

●Can use raw materials which are generally not allowed to be extruded.

●Can avoid the weakness of the joint on short-glass fiber reinforced thermoplastic materials.

●Less recycled material, can reduce the risk of damage to sensitive polymer decomposition and fiber.


Less flash weight:

●Lower investment cost, using smaller extruder and lower clamping force, no need expensive deflashing device, using smaller ancillaries(including crusher, mixer, conveyor and cooling system).

●Lower production costs, energy saving, less energy consumption on motor and heating due to using less energy on less raw material plasticizing and cooling.


Unique Radial wall-thickness control system Of 3D Air Ducts Pipe Extrusion Blow Molding Machine

Radial Wall Thickness Control System (RWDS)

There was a fundamental problem with hollow parts with large bends before, that the wall thickness of the inner and outer diameters at the bend was not balanced, due to different stretching conditions. When using horizontally arranged molds, similar problems arise because the parison contacts the mold in advance. For this reason, SINOTECH designers have developed a radial wall thickness control system (RWDS), which can adjust the wall thickness of even small die diameters at will within its range.
