Plastic Extruder Manufacturer - TaiZheng

With physical foaming significant material savings are possible for many extrusion processes. Foam extrusion systems from TAIZHENG are setting new standards in the production of microcellular foam products with very homogeneous cell structure. Unique key components and broad process knowledge are the basis for our innovative technologies. Our systems work with eco-friendly CO2 and N2 blowing agents and are very easy to integrate into existing or new extrusion lines.

The physical foaming extruder mainly used to making coaxial cable and communication cables. Coaxial cable which used as a transmission line for radio frequency signals. Its applications include feedlines connecting radio transmitters and receivers with their antennas, computer network (Internet) connections, digital audio (S/PDIF), and distributing cable television signals.

The gas dosing stations we are using is from Germany technology,especially developed for physical foaming, for highest dosing accuracy and very safe and easy operation.

High efficiency static and dynamic mixing systems with very short installation length.

Unique cooling mixer technology for outstanding foaming results.

physical foaming extruder

Different payoff and take-up for wide reel range.

Extrusion process:skin/foam or skin/foam/skin.

Different nitrogen gas injection for low pressure foaming or high pressure foaming

The physical foaming extrusion line for coaxial cable with PE insulation.

With self-centering crosshead ensure good cable quality and easy operation.

Crosshead with bypass unit for minimum crape material during start, save material cost.

With dual payoff and accumulator, non-stop production during change take-up bobbin.

Excellent tension control from start to end, ensure constant cable OD.

Foaming percentage:imported high-pressure nitrogen injection system(MAX.82%);low-pressure nitrogen injection system(MAX.75%);
