ABS or PC Electroplating Production Line
The plastic plating production line is widely used in industries as car decorative parts, mobile phone decorative parts and logo signs. With the enlargement of the application of engineering plastics, plastic plating are expanding the using scope, mainly for the ABS, PC electroplating processing.
In the development process of automobiles and motorcycles pursuing lightweight and luxurious beauty, plastic electroplating has played a vital role. From door handles, car trademarks, nameplates, car interiors, reflectors, dial decorations to operating rod heads, steering wheel decorations, high-end wheel shell covers, grilles, decorative strips, etc., a large number of plastic electroplated products are used. Not only are automotive decorative parts, there are also a large number of plastic electroplated products on motorcycles and bicycles.

2. Circuits with serious consequences for electrical interference do not use a single control cable which includes:
(1) weak signal control loop and strong signal control loop;
(2) The loop of low level signal and high level signal;
(3) The same control cable should not be used for weak phase control loops of AC circuit breaker phase-phase operation. However, for each pair of return conductors of the weak current loop belonging to control cables that are not of the same root, it may form a ring arrangement when laid, and the potential may be induced under the electromagnet wires of similar power supply, and the value may be for weak current loops. Low-level parameter interference has a greater impact, so it is advisable to use a single control cable for the return conductors.
3. Metal shielding and shielding grounding Metal shielding is an important measure to reduce and prevent electrical interference, including total shielding, sub-shielding and double-layer total shielding of the core. The selection of the metal shield type of the control cable shall be based on the influence of the possible electrical interference and shall be included in the measures for comprehensive suppression of interference to meet the requirements of reducing interference and overvoltage. The higher the requirement for anti-jamming effect, the greater the corresponding investment. When using steel tape armoring and steel wire braiding general shielding, the price of the cable is increased by about 10%~20%.
The control interference in the strong electric circuit, due to its strong signal, can be controlled by a control cable without metal shield, except in the UHV power distribution device or in close parallel with the high voltage cable. The control cable used in the weak current signal control loop should be controlled with a metal shield when it is located in an environment where interference exists and there is no effective anti-jamming measure, to prevent the electrical interference from causing malfunction to the low-level signal circuit. Or make insulation breakdown, etc. If the control cable of the weak current circuit can be pulled away from the power cable by a sufficient distance, or laid in a steel pipe, the external electrical interference may be reduced to an allowable limit.
1. The grounding of a spare core of the control cable has proved that when a spare core in the control cable is grounded, the amplitude of the interference voltage can be reduced to 25% to 50%, and the implementation is simple, and the cost of the cable is increased only slightly.
