In recent years, many domestic used equipment has been purchased. Some of them are very successful and can be used normally in a short time. Some are not very successful in buying, equipment can not be put into operation for a long time, or put into operation but the efficiency is low, the failure rate is high, downtime maintenance time is long. Some are even in the box. This raises a question for us. How should we buy and operate second-hand equipment and make decisions, so that we can achieve the goals of less investment, quick results, and the promotion of production development?
Second-hand equipment market domestic and imported instruments are not evenly divided Although China's metrology instrumentation industry has a certain degree of development, it is far from meeting the growing urgent needs of national economic research, national defense construction, and social life. China's metrology equipment products, Most of them belong to medium and low-grade technology, and key indicators such as reliability and stability have not yet fully met the requirements. High-end, large-scale equipment and equipment are almost all dependent on imports. Mid-range products and many key parts and components, foreign companies also account for 60% of the domestic market. Above share. This is the status quo of domestic instruments. As for used instruments, most users will choose imported instruments, but domestic equipment is very convenient in this respect.
Second-hand equipment purchase leading factors Pre-equipment preparation for second-hand equipment procurement, like ordering new equipment, give high priority. You can't relax your requirements because they are cheap and functional. Unlike the ordering of new equipment, its specifications and functions have to be checked according to the needs of a typical process. It is also necessary to understand and master the year of manufacture, the status of service, and the type of control system. According to users' generalizations, when buying second-hand equipment, the following issues will be considered: second-hand reasons, quality, price, and after-sales. Everybody buys second-hand equipment and understands the causes of used equipment. It is an important lesson and an important reference indicator. The reasons for the use of used equipment are as follows: (1) Due to the earlier production date, the production efficiency has been Can not meet the needs of production. This kind of equipment is in service for a long time and its function and function quality are normal. (2) Idle because of factory closure or steering. This equipment has also been in service for a long time and its function and function quality have been tested. Quality is the premise, the instrument can not be used cheaply or not, quality is the last word, for the judgment of the quality of the instrument, to do a set of performance verification is a very good method to confirm that there are no problems in the accuracy of the instrument. Price is the key factor. The price cannot be too high. It should be better to have an advantage below 50 percent.
After-sales service should be the customer's most concern, the warranty contract should be more than half a year, you can pay to purchase an extended warranty contract (1 year), along with maintenance equipment. If you do not provide an extended warranty contract, a second-hand equipment company professional engineer can provide on-site maintenance. Be sure to pay attention to the warranty conditions, as well as the unused or used equipment sold by the maintenance personnel themselves, that is, new and refurbished quantities. If there is a lack of maintenance documents and the warranty conditions are poor, then purchase this used instrument product. For test equipment, whether the new or refurbished product is subject to inspection or the risk is greater, it must be carefully considered.
Second-hand instrument market ecological analysis
The first factor in the used equipment market is that new equipment is too expensive, and the demand for production and R&D departments is constantly increasing. In addition, the product's own product update cycle is very slow, so as to reduce costs and ensure production. From the perspective of buying used equipment is a good choice. However, the secondary market is not standardized, and the supply channels are not uniform. After-sales service can not be guaranteed. To a large extent, it brings a bottleneck to the secondary equipment market. As we all know, the price of each instrument is not cheap. Now we purchase instruments. Customers not only value the quality of the instrument, but also regard the quality of post-sales service and technical support. Buying an instrument requires many follow-up services. Instruments and follow-up to the instrument are an organic whole.
