Thoughts on the localization of spare parts
Thread Content
Most of the equipment in our unit is imported from abroad; it would not be an exaggeration to say that it comes from eight different countries. I am absolutely in favor of using domestically produced spare parts. Leaving aside the issue of price, just the lead time for obtaining them is enough to convince me: it takes at least 2 or 3 months, and sometimes even 6 or 7 months, to get spare parts from Germany or Switzerland, and there’s also the need for constant communication via phone, fax, and email. If something urgent arises, by then it’s already too late. If it’s a domestically produced part, the manufacturer’s representative can come and examine the sample and discuss things directly; it can be done in just a few weeks at most. Of course, I admit that most original parts from abroad are of better quality than those made in China, but I’ve also encountered cases where domestically modified spare parts had their lifespan doubled. So in my opinion, as long as it can meet the needs, localization should be pursued as much as possible. The problem is the attitude of those in charge of manufacturing processes and production toward localization. Put nicely, it’s called \"skepticism,\" but in reality it amounts to \"denial.\" Once there are problems with the locally produced spare parts (and although great care is taken during localization tests, it’s almost impossible to ensure that nothing goes wrong every time) ； And in fact, in some cases even after installing imported parts, things still go wrong.) There are rules regarding whether parking for one hour costs so much and how much it costs to buy imported spare parts; they seem to not do any calculations at all, which really frustrates me. I wonder if anyone else has had a similar experience.
I agree with you; the pace of localization is somewhat difficult for us. Some spare parts can definitely be localized through reverse engineering. The key lies in the choice of material.
If a problem arises, it will be difficult to handle
Localizing equipment is a path we must take; we can’t keep letting foreigners dictate our actions. By imitating and studying foreign technologies, our country’s scientific and technological level can also be improved. Of course, we might take some detours, but we can’t give up just because of that. The moon isn’t always round in foreign countries, and domestic spare parts also have a long service life.
I agree with what the original poster said. However, I think some important transmission components still need to be imported, while it’s sufficient to use domestically produced versions for those common, wear-prone parts.:victory:
It’s indeed very difficult to replace imported spare parts with domestic alternatives. Take the bearings for German GHH turbines, for example – several domestic manufacturers have tried to produce them, but either they don’t fit or they can only last for a month or so (and we can only use them as a temporary solution). The German versions can last for several years; there’s still no comparison at present. But we need to keep trying, and success will eventually be achieved!
For valuable and vulnerable spare parts, localization is possible if there is a market. Now that the processing and measurement technologies have improved, it’s no problem to do a good job. The key issue is that laypeople don’t understand this; for the localization of spare parts, we still need professionals from Conghua Machinery. :)
Using domestic spare parts is now quite common; foreign spare parts have long delivery times and high prices
The localization of imported equipment components should be promoted. When selecting domestic manufacturers, the following principles should be followed: 1. Domestic manufacturers should have a track record of producing similar equipment； 2. Provide domestic manufacturers with information on the physical characteristics of the materials to be used, the operating conditions of the equipment, and the composition of the media, to facilitate their selection of appropriate materials ； 3. If conditions permit, the equipment can be trial-assembled with domestically produced components at the manufacturer’s site, which ensures the precision of component processing and assembly ； 4. The manufacturing drawings for domestically produced components that have been finalized must be kept on file (proper arrangements should be made during the initial signing of technical agreements and contracts) to avoid falling into a disadvantageous position in case of disputes later on. The above are my experiences.
