Cable wire in the field of extrusion machine terminology is extrusion, in plastic granulation is also known as extrusion molding or flame retardant plastic. The recycled rubber is also known as pressed out. It means that the raw materials are melted by the heat and pushed forward by the extruder screw according to the efficacy between the extruder barrel and the extruder screw and continue to be made into a variety of cross-sectional products or semi-products according to the engine of a production processing method.


The insulation and outer layer of the cable and wire are processed according to the extruder.

Generally, according to the type of polymers to be produced and processed and the product or semi-finished product to be processed, the extruder, engine and die opening, and its shaping and traction belt are selected to assist the equipment. The extrusion process standards such as the extruder screw speed ratio, engine working pressure, raw material temperature, and its shaping temperature, traction belt rate, etc. are then defined. In the whole process of extrusion, the raw material generally needs to pass through the plastic refining, but the way of deformation varies. For example, extruded plastic often requires refrigeration to set the shape of the dry solid, and extruded plastic semi-finished processing, pending further vulcanization of rubber. The choice of different extrusion machinery and equipment and processing technology can obtain different products.

In cable manufacturing, the extruder is a key piece of equipment in its automated production. According to control, the extruder's speed can control the size of the outer diameter specifications. To control the size of the outside diameter specifications, you need to know the size of the outside diameter specifications. The cable diameter meter is just the right cable production line used in the outside diameter online monitoring instrument.


The cable diameter gauge can be installed in front of the refrigeration stainless steel sink and also after the stainless steel sink. When installed in front of the stainless steel sink, because the precise measuring head is close to the extruder, the opinion feedback control can immediately get excellent control of the actual effect, but the rolling plate is not dry solid, set the tolerance value should be moderately adjusted. Installed in the stainless steel sink after the precise measurement to obtain the specific value of the outside cable diameter, more reasonable and reliable, but the amount of control backward, the control of the actual effect is slightly weaker. In addition, pay special attention to the measured cable dry, or the contraction of water outside the cable will endanger the measurement accuracy. The specific application should be based on the level of the measured object wet, with a moderate increase in the tolerance value settings.


A cable diameter meter is the choice of PID adjustment frequency converter or electronic speed regulator to control the rate of the extruder or discharger and then the purpose of controlling the outside diameter specification of the cable wire and cable. Have the diameter meter added to the production line, get the finished cable diameter fluctuations significantly reduced, the quality of the finished cable improved, and get more and more specifications of the finished product.


A cable diameter meter for a small desktop all-in-one machine diameter meter can be installed in the production line to carry out online monitoring. Only pre-buried installation parts can complete online monitoring, control, deviation alarm, data show, external show a variety of roles to improve the level of automation technology in the manufacture of the cable wire.
