In recent years, with the rapid development of China's economy, the wire and cable industry has also grown. In 2017, the scale of China's wire and cable industry reached 1.2 trillion yuan, an increase of 6.3% over the same period of 2016. The scale of the industrial market has maintained a rapid and steady growth. The production and sales of wire and cable in the country have surpassed that of the United States to reach the top in the world.
During the "Thirteenth Five-Year Plan" period, China's distribution network construction is expected to reach a total investment of 1.7 trillion yuan, with an average annual investment of 330 billion yuan. It is planned that by 2020, the length of the high voltage distribution network will reach 1.01 million kilometers and the length of the medium voltage distribution network will reach 4.04 million kilometers.
At the same time, the “Thirteenth Five-Year Plan” also formulated a rural power grid transformation and upgrading plan with a total investment of over 700 billion yuan. It can be seen that the demand for the power cable market in China during the “Thirteenth Five-Year Plan” period is strong.
With the increase in the demand for wire and cable, improving efficiency and compressing costs have become a major problem for manufacturers. Therefore, many manufacturers began to look for new production processes.
Take the cable surface marking process as an example. After the original ink jet coding was replaced by the laser marking technology, there was a full range of improvement in terms of production efficiency, processing effect, and production cost.
Ink jet coding: The cost of an ink jet printer supplies is 2 to 4 million yuan per year. It is understood that the cost of ink purchased by a medium-sized company for one year will reach 400,000 to 500,000 and even millions.
Laser marking: No need for consumables costs.
Ink jet coding: Ink jet printers are affected by changes in the working environment and temperature and humidity, and are prone to clogging of the ink path and nozzles. The failure rate is high and the equipment life is short.
Laser marking: It can achieve stable and continuous production for 24 hours, and the service life of fiber laser marking machine can reach more than 100,000 hours.
Ink jet coding: manual or mechanical operation, can achieve 1 or more lines of character markings, the relative speed is slow.
Laser marking: The use of computer-integrated intelligent operation can realize automatic feeding, automatic marking, automatic material storage, saving time; faster marking speed.
Ink-jet printing: Ink-jet printers have many processes that require constant ink addition. The nozzles must be frequently cleaned for maintenance. Consumables are limited in storage.
Laser marking: It can realize automatic on-line flight marking and reduce the number of processes; and the development speed is fast, and the markings can be constantly replaced. The storage capacity is large, and basically no manual maintenance is required, and the operation is simple.
Marking effect comparison
Laser marking machine as an advanced marking device, because of its many advantages are replacing the traditional marking equipment, becoming the latest choice of wire and cable manufacturers. Smart manufacturers know how to choose between ink coding and laser coding?
