I believe everyone is familiar with the screen changer on the granulation production line, that is, the manual or automatic switching device of one or more filter screens, which is used to filter out foreign particles and impurities when the plasticized material flows through the filter screen. However, when it comes to what should be paid attention to when purchasing, it is not very clear for many first-time users. Therefore, the following purchase precautions are sorted out. Let's take a look.

First of all, when purchasing a granulation screen changer, the salesperson should clarify the product-related information, such as model, material, specification, sealing structure, slag discharge method, applicable material pressure, heating power, etc., and judge whether this product meets their own needs by comparing accurately.
Secondly, it is necessary to focus on checking the quality information of the product. Such as the production date, whether there is a certificate of conformity, whether there is a qualification certificate required by the industry, whether the various approval certificates required for leaving the factory have been obtained, etc. Products with these quality inspection information are worth buying and trustworthy.

Then when purchasing granulation screen changer products, you should also compare the prices of the products. You must look at more and compare more to avoid pitfalls and take fewer detours.

Finally, when purchasing, you should try to choose a powerful granulating screen changer factory in the market and purchase its products, so that both the quality and after-sales service will be relatively guaranteed.

In summary, this is an introduction to the matters that need to be paid attention to when purchasing a granulating screen changer. I hope it will be helpful to everyone when purchasing.
