Analysis and Prospect of product quality in packaging machinery industry (IV)

3. Analysis of quality problems and causes

3.1 enterprises are affected by external market and internal management reasons

with the continuous deepening of reform and China's transition from planned economy to market, there is no lower price component B to participate in the economic transition, and the number of private enterprises in packaging machinery production enterprises continues to increase, Packaging machinery products have changed from the original short supply to oversupply, and the market competition is extremely fierce. Compared with other packaging machinery, the product structure of some packaging machinery is relatively simple, and there are supporting parts and components, so it is very easy to organize production, even three or five people can produce. Some small workshop enterprises lack quality awareness, resulting in the existence of unqualified products

in order to save materials and processing costs, some vacuum packaging machine enterprises arbitrarily reduce the thickness of the stainless steel plate of the box. The thickness of the plate of the box is not enough to withstand the low vacuum pressure for a long time. Users report that the cover of the box will break after half a year of use

in order to reduce costs, some enterprises use vacuum pumps with poor performance, small vacuum pumps for large vacuum chambers, or two small vacuum pumps instead of one large vacuum pump, which reduces production efficiency

some enterprises choose electrical components with poor reliability, resulting in unstable operation performance, short service life, slightly longer service time, quality problems are exposed, and users have more complaints

although some of the items mentioned above are not within the standard requirements or testing items, they are hidden dangers of poor product quality and the reason for more complaints from users. Therefore, although the pass rate reflected in the two random inspections is not very low, it cannot be said that our product quality is very optimistic

3.2 poor awareness of product logo

the label of the product should be fixed on the obvious part of the product, and the main technical parameters should be indicated so that users can operate and use it correctly. Some enterprises do not have labels or instructions, which brings inconvenience to users and even unsafe factors. In addition, in this spot check, it was found that some products did not have grounding devices, and the vacuum packaging machine products of six enterprises had obvious grounding marks, but the products of other enterprises did not, but it was significantly better than the spot check of the last strapping machine, indicating that the safety awareness of enterprises has been strengthened, but it is not enough. The weak product safety awareness of enterprises has become a common problem in the packaging machinery industry

the enterprises with high quality in the two spot checks have common characteristics, with perfect technical equipment and inspection means, strict internal management of the factory, most of which have passed the ISO9000 quality system certification, and a complete and strict quality management system. The products not only pay attention to the internal quality, but also pay attention to the safety and convenience of the operator. The internal quality, appearance quality and operation performance of the products are good, and the inspection items are not only qualified, And the indicators of its key projects are far beyond the standard requirements

the spot check will help to further understand and grasp the development trends of the industry, provide direction for enterprises to improve product quality, provide basis for the government's macro decision-making, and also help relevant departments actively organize and guide the production and quality management of enterprises

in the spot check, we found that at present, China's packaging machinery enterprises are relatively small in scale, imperfect in technical equipment, relatively low in management level, weak in self-development and technical design and development ability, and single in product variety. The technical content and added value of the product are low; The new product development cycle is long, and it cannot respond to the market demand in time and provide the products urgently needed by the market and users in time. The main energy of enterprises is spent on the expansion of quantity. The investment in the improvement of quality and scientific and technological progress is seriously insufficient. The products are repeated at a low level. Many enterprises produce the same products, so many products cannot be sold. Low price competition has threatened the survival of enterprises; In addition, the product safety protection measures are poor, and the safety awareness is not strong, which leads to the low competitiveness of domestic products with foreign markets. At present, China's packaging machinery products generally have unstable quality, single performance, high cost and low technical content

with China's entry into the World Trade Organization (WTO), the entry of international advanced technology, equipment and management experience is bound to have a huge impact on China's newly developed packaging machinery industry, and enterprises are facing unprecedented severe tests. "Here comes the wolf!", We should give full play to our own advantages according to our own characteristics. In order to seek better and long-term development, packaging machinery enterprises must constantly develop new products, improve the technical gold content of products and the reliability of machinery to adapt to the current development situation of rising interest, standardize high-quality service standards, and strive to do a good job in after-sales service. Only in this way can packaging machinery enterprises develop better and have the strength to compete with "wolves", and even go abroad to compete with the products of foreign advanced enterprises and "dance with Wolves"

the ever-changing packaging corresponds to a wide variety of packaging machinery. With the continuous improvement of people's living standards, people's consumption mode has changed from food and clothing to enjoyment, and the market that packaging machinery can open up is becoming larger and larger. Some of our enterprises often like to focus on a "cake" and compete with each other. Why can't we broaden our horizons and join forces to expand the "cake", or open up new fields to make their own "cheese"

it is hoped that packaging machinery enterprises will participate in industrial technology exchange activities, exchange information with each other, learn advanced management experience, improve process equipment, enhance quality awareness, and further improve product quality

during the entrusted inspection for enterprises at ordinary times, we found that some enterprises are doing reliability tests voluntarily, from which we can see the possible quality problems and safety hazards from the figure below, unlike some enterprises that regard the product inspection of the quality supervision department as a routine business and deal with it. This spirit makes us very moved. If we packaging machinery enterprises can really realize that "product quality is the life of an enterprise" is not a fashionable clich é, but a truth, can our product quality be bad, and can our enterprise be underdeveloped

as industry workers, we sincerely hope that packaging machinery enterprises can continuously improve their overall quality, strengthen quality management, and continuously improve their technical level and develop new products, so as to remain invincible in the increasingly competitive market

the current difficulties are temporary. As long as we change our ideas and jump out of misunderstandings, the sun will be bright tomorrow. We are willing to provide information, services and technical support for enterprises, and build a platform for enterprises to communicate information. Let's join hands to improve the overall level of the packaging machinery industry and strive to explore, revitalize our common industry and create a brilliant future for national industry
