Engineers and procurement model selection of the mechanical and electrical components such as connectors, switch
In stealth for so many years in the connector industry, contact with so many various types of customers, their engineer when using connectors, switches, such as mechanical and electrical components have their own habits and considerations. As a connector, switch, such as mechanical and electrical components selection considerations, under normal circumstances is the following:
1, meet the design requirements: this refers to the connectors and switches, such as mechanical and electrical components need to be in size, structure, material, precision, consistency (life), compatibility, weatherability, durability, reliability, etc, not only should conform to the product demand of static, and the need to conform to the product in the actual dynamic in the process of transportation, and in the actual use requirements.
2, meet cost requirements: according to different industries, different products, market orientation, different customer market area to the whole products have corresponding different positioning. These different product positioning determines the market pricing, according to the market price if you want to maintain a certain profit will it cost control in a certain range of products will have corresponding competitiveness. This determines the idea and direction of the engineer on the component selection.
3, meet production process requirements: most customers purchase this kind of components are used to produce parts, then assemble to the machine. The selection is important to consider when we are in the in the process of parts production and assembly process, even when using the manufacturability in the process of maintenance in the future, be sure to meet these technical requirements.
4, meet the requirements: it is in the product selection to meet the above three requirements is not enough, even by the above three measures is the perfect selection, if it will be very hard to purchase, that is to say, purchasing channels, or delivery date not sure delivery time is very long, or the product is original non-standard products; These will bring big trouble to the production of the actual. Improper selection may to procurement, business department, bosses and clients nerve brings the huge challenge.
To work in some mature products of enterprises and experienced engineers, according to enterprise long-term accumulated before selection of data and experience very easily, and will do the comprehensive consideration when a selection;
But because our country economy high speed development, and constantly have new products, new businesses and thrive, this early in the process of the enterprise itself has no long-term data accumulation, engineer's understanding of connectors, switches, such as mechanical and electrical components easily when I was not deep enough to avoid ill-considered when selection.
Such as cost, products in a large company connector usage is very large, import connector is used, then in order to save costs into domestic connector, so engineers have done a lot of testing, test through think there is no problem after using the domestic connector production. In the process of production have not found what problem, but after the product launch, this batch of products under warranty repair rate is increased, leading to the company to pay a large amount of warranty costs, at the same time to the company's reputation has brought huge damage. This is due to the company's products are actually use environment is in a state of shock, temperature and humidity will be constantly changing, so easily lead to consistency is not connector on a large number of long-term conduction defective rate rise obviously appeared in practical use, here said the consistency and reliability of the said is not test at the time of the ten, hundred, thousand, or even, for some products may be in the hundreds of thousands, millions of Chinese to apparent difference.
Such as for mine, mine, tunnel, outdoor engineering machinery equipment and so on use of connectors and switches, will focus on considering the corrosion resistance of the product, consistency, structure, to temperature and humidity weather resistance, etc., for the switch in consideration of normal life at the same time in harsh environment is to consider the structure of the sealing, dustproof, waterproof performance, such as whether meet the requirements; Japan NKK electromechanical switch product is doing very good in this aspect, can do it under the bad environment can maintain a high reliability and high life, use of such products in production is to increase the cost, but can save a lot of maintenance costs later on, more important is in customer mind set up the image of high quality products, bring more value to customers.
For some products, the maintenance cost is higher in the tens of millions of such components can't to save costs lead to after-sales costs increased dramatically, when engineers, business department and the boss will feel regret at the beginning, then we will have a headache, then maintenance costs, damages, loss of goodwill is inevitable, the following orders can also be a problem.
For some high value, high quality requirements, high maintenance cost of the products in such components selection should adopt a relatively conservative mentality, avoid penny wise and pound foolish.
Engineer in connectors, switch, therefore, this type of model selection of the components must be the actual product positioning, product use environment, the batch of products, product maintenance and so on comprehensive consideration of the late; In easy to purchase more communication with the supplier, may, when necessary, please suppliers involved in the selection work, listen to suppliers of professional advice and opinion, it may get twice the result with half the effort little detours. In meet the manufacturability, should work with production engineer and do the necessary tests and actual batch trial-produce work, ensure the process of mass production.
