COD cable cluster tube production line (COD multi-channel cable cluster tube equipment) is Cui's plastic machine in recent years research and development, and the first in the domestic launch of new products, with high output, simple process, high degree of automation, easy to operate and other characteristics, fill the domestic gap, in the domestic leading level. The COD pipe manufactured by the COD pipe production line is also known as the multi-channel bellows, corrugated cable protection pipe, it is composed of a number of internal cable tubes and outer tubes as a whole, COD has created a new era in this field by assembling the inner tube (3 to 7) already manufactured in the process of reproduction in the outer tube. Both the inner tube and the outer tube are made of HDPE(high-density polyethylene), with a high degree of elasticity, although the outer tube is equipped with most of the inner tube, it can still be well wound on the tube frame.

C.O.D is an abbreviation for Corrugated Optic Duct. This is a new generation of high-performance optical cable conduit developed with a new concept on the basis of summarizing the advantages and disadvantages of various optical cables and cable conduits in the past. It uses the modified HDPE with very low friction coefficient as the main raw material, the structure takes the edge wall tube with very low friction coefficient as the sub-tube, and the corrugated pipe with high pressure resistance and easy bending as the mother tube. It is characterized by high pressure resistance, bendability, differentiation, and easy construction, and has incomparable advantages over many other products in terms of physical properties, service life, and engineering construction.
