Domestic printing and dyeing machinery and equipment solve the "general" dilemma
Release time：2020-08-29 Views：
In the analysis results, 62% of enterprises believe that domestic equipment can meet process requirements, but at the same time, 58% of user companies have a "fair" impression of domestic equipment. For a long time, domestic printing and dyeing machinery and equipment manufacturers have been continuously improving their technical level to meet the process needs of user companies. However, statistics show that most domestic printing and dyeing equipment has been recognized by downstream companies in terms of process requirements, and their overall impression is still It is considered inferior.
Solving the problem of "general" evaluation has become an urgent issue for domestic printing and dyeing equipment manufacturers.
In the questionnaire, there are 4 options for the overall impression evaluation of domestic printing and dyeing equipment: very good, good, fair, and very poor. Many participating companies said that the basis for selection is actually what value production needs the machine can meet.
Printing and dyeing enterprises often adopt this production mode: domestic printing and dyeing equipment produces conventional varieties, and imported equipment produces high value-added products. "Most of the domestic equipment can meet the production of conventional products. However, for some high value-added products with special requirements, domestic equipment is often not enough." Liu Xinghong, mechanical and electrical engineer of Huawan Carbon Fiber (Group) Zhurong Co., Ltd., said the company tried to use domestic equipment It is very difficult to produce high-count and high-density varieties with a width of 63 or more. Most of the domestic equipment can only meet the production of conventional varieties, which is the main reason why user companies rated domestic equipment as general.
In Huawan Company, continuous padding machines and mercerizing machines are domestically produced equipment, while some rotary screen printing machines and pre-shrinking machines are imported products.
It is easy to see from the composition of the equipment that domestic equipment is basically concentrated on the conventional links of printing and dyeing, while equipment that can increase the feel of the product and thus increase the added value is occupied by foreign products.
The equipment composition of many printing and dyeing enterprises is similar to that of Huawan. Cai Mougao, an engineer of Guangdong Shunde Jinfang Group, believes that domestic continuous equipment such as mercerizing machines, setting machines, and woven dyeing and setting equipment are satisfactory; but finishing equipment that increases the added value of products, such as shrinking machines The level of declining machine, etc. is relatively poor. "This may be because the continuous equipment has been developed for decades, and many problems have been corrected." Cai Mougao said, "but other equipment still has many problems to be solved."
Why domestic equipment cannot meet the high value-added production needs of enterprises? On the surface, the performance of domestic equipment that can provide high value-added links needs to be improved; but at a deeper level, this reflects the general gap in mechanical performance and automatic control of domestic printing and dyeing equipment.
In terms of mechanical performance, the outstanding problem is that the quality of bearings, fans, top rollers, etc. are often not good enough, causing the overall performance of the equipment to decline. In some domestic equipment used by the Jinfang Group, the top rollers deformed or even rusted after being used a few times, and the fan became very noisy within 2 to 3 months. This makes the company cautious when purchasing domestic equipment. Chen Junfei, chairman of Xinfa Textile Printing and Dyeing Co., Ltd. believes that a large number of low-quality mechanical and electrical products and textile machinery accessories are circulating in the market, and many companies lack effective supervision and restriction on outsourcing and outsourcing parts, resulting in the inherent quality of domestic printing and dyeing equipment. Hidden dangers, the overall image is difficult to change. "This also makes the machine's overall failure rate higher, and the time and labor costs for repairs are larger," he said. The problem of automation control is one of the problems that users strongly reflect on domestically-made equipment in this survey. In the printing and dyeing process, the requirements for temperature control and humidity control are very strict. If there is no accurate automatic control, deviations will easily occur and affect the final product quality. Liu Xinghong of Huawan said that they bought a batch of domestic padding and dyeing equipment in 2002, but the automatic control function at that time was not perfect, including temperature and fabric moisture detection, which had to be done manually. He hopes that the domestic printing and dyeing machinery can improve the automation control level as soon as possible, especially the improvement of the tension control in the online inspection and control, the moisture detection of the dyeing machine and the pH control of the cloth.
maintain the advantage
Although user companies have many complaints about the automatic control of domestic printing and dyeing equipment, they are relatively satisfied with the electrical control of the equipment. "Domestic is not much worse than imported ones." said Cai Mougao of Jinfang Group. And because of product prices, they are more inclined to use domestic electrical control products. Zhao Zhongxing, general manager of Changzhou Donggao Dyeing and Finishing Co., Ltd., agrees with this approach. However, he also believes that the real advantages of domestically-made equipment at present are the low one-time investment, short cycle and quick results. “For example, the investment of a domestically produced setting machine is generally only about 1/4 to 1/5 of that of imported equipment, and the maintenance cost is lower and the reliability is better.” He said.
The results of this investigation can also confirm the above conclusion.
When evaluating domestic equipment, low prices of products and accessories and good after-sales service are the main advantages of its advantages. Liu Xinghong from Huawan said that they had imported a drawing machine from Bruckner, Germany from an agent in Tianjin. Later, the inverter failed, and they sought repairs from Tianjin agents. The answer is: The replacement price of the 11-kilowatt inverter is 58,000 yuan, plus the maintenance personnel's road expenses, the total is close to 70,000 yuan; moreover, Huawan also needs to suspend the entire production line for at least half a month for this. In the end, they bought another inverter with the same performance through Changzhou Hongda Electric Co., Ltd. for only more than 8,000 yuan.
The problem that Huawan Company encountered is not an individual case. Many printing and dyeing companies have similar experience. Some people suspect that the advantages of domestic printing and dyeing equipment in the above aspects may not be helpful to improve the evaluation in the eyes of users. The basis is that equipment performance has a decisive effect on the development of the enterprise. However, the fact that still cannot be ignored is that the advantages of domestic printing and dyeing equipment are actually formed by domestic enterprises on the basis of understanding the local regional environment. If domestic printing and dyeing equipment continues to maintain its advantages in after-sales service while improving the performance of the machine, it is believed that the "general" problem of domestic equipment evaluation will eventually be solved.
