gui chao cable news: flexible cable sheath extrusion process how to choose?-非凡电子娱乐

in the process of flexible cable manufacturing, the extrusion of cable sheath plays a very important role.

cable sheath extrusion method and extrusion die is very important to sheath quality.

at present, there are three kinds of extrusion methods: extrusion, pipe extrusion, semi extrusion.

the structure of the three molds is basically the same,

the difference lies in whether the front end of the mold core is provided with a tubular bearing diameter or the position of the tubular bearing part of the assembly is different from that of the die sleeve.

at present, most of the flexible cable sheath is extruded,

in the small part, extrusion tube and semi extrusion tube extrusion. the die core of the extrusion die does not have a tubular bearing portion,

the mould core is stuck behind the mould bearing diameter, and the molten plastic is formed by the pressure of the mold core.

therefore, the extruded sheath structure is compact and the surface is smooth.

the extrusion tube type die core is provided with a bearing diameter part, and the front end of the mold core bearing diameter extends out of the end surface of the die sleeve or is flush with the end face of the mold sleeve.

because of the existence of the tubular diameter part of the die core, the molten plastic is not directly pressed on the cable core as the extrusion type,

instead, it is pressed into the tubular bearing part to form a tubular shape, and then is coated on the cable core through a stretch.

as a result, both the inner and outer walls of the extruded sheath are smooth and may be more aesthetically pleasing than the extruded sheath,

and the protection of the existence of gaps in the suite, easily lead to changes in the structure of the conductor, affecting the normal operation of the equipment, or even break the core line.

there is no gap between the sheath and the conductor,

don't exercise in there when towline towline cable structure changes, to ensure the normal operation of the equipment.

flexible cable professional manufacturers recommend wiring used in yi fernando towline when choice of extrusion molding towline cable sheath;

if it is used for robot arm wiring installation, it is necessary to follow the mechanical arm frequently,

the cable can be used to make the service life longer.
