Wire Extrusion Screw Barrel is used to carry electricity, to bear the mechanical loads, to transmit telecommunication signals, for heating jewellery, clothing, automotive or any industrial manufactured parts like pins, bulbs and needles. A cable is used for power transmission, for telecommunication signals or to carry electricity.
Wire Extrusion Screw Barrel
A wire is used to carry electricity, to bear the mechanical loads, to transmit telecommunication signals, for heating jewellery, clothing, automotive or any industrial manufactured parts like pins, bulbs and needles. A cable is used for power transmission, for telecommunication signals or to carry electricity.
Hence wire and cable are very important in our life. Wire and cable extrusion screw barrel helps to produce wire and cable per request.

Quality Inspection
Quality is a very important step during production. For making a quality screw barrel, all tolerances should be fulfilled and all dimensions should be correct and put in records.
We provide inspection report, material certificate for every of our supplied screw barrels.
Packaging
Packaging is the last but very important step before shipping. A strong and smart packing box is also part of our quality. It is not only used to protect the screws barrels well during transportation, also provide an easy way for our customer to unpack.
