Talk About The Advantages And Disadvantages Of Steel Molds And Aluminum Molds
Everyone knows the process of rotational molding, and the application fields of rotational molding are also very wide. Nowadays, rotational molding products can be used in many aspects, but we all know that making rotational molding products requires molds. When making rotational molding products, is it better to use steel plate mold or aluminum mold? Whether the model is good or not, I personally think it mainly depends on the product. Let’s talk briefly about it.
Compared with rotational molding steel plate molds and rotational molding aluminum molds, which one is more suitable for rotational molding process has always been a controversial topic in the rotational molding industry. In this regard, I think this is a meaningless and meaningless dispute. If there is really a result, I think this answer is for the mold manufacturer and is not an objectively correct result. Some people may also ask, which is better, aluminum mold or steel plate mold? All I can say is, for example, if you want to buy a pair of shoes, do you think sports shoes or leather shoes are better? Of course, only the ones that suit you are good. We will choose different types of shoes based on personal preferences or uses. So the debate about which one is better between rotomolding steel plate mold and aluminum mold can come to an end. It seems that there is only one answer, as long as it is suitable, it is good.Therefore, at the beginning of mold development, your objective, correct and rational choice is the most important.
However, at the beginning of the development of rotational molding products, we still need to carefully consider which type of rotational molding mold to choose based on the characteristics of the product to be developed. This is very important. Here is some knowledge about rotomolding steel plate molds and aluminum molds for your reference.
Advantages and disadvantages of rotational molding aluminum molds:
In terms of production technology, rotational molding aluminum molds are divided into cast aluminum molds and aluminum plate engraving molds. The former is a traditional process, and the process flow is roughly drawing → wood mold making → resin mold → casting → finishing. The latter is a product of the digital age. It is formed in one step through a CNC machining center. It has the advantages of beautiful appearance and accurate size. The disadvantage is that it requires the volume of the mold and cannot make large rotational molds. Cast aluminum molds and aluminum plate engraving molds are made of cast aluminum or aluminum alloy. In theory, because aluminum has good thermal conductivity, the rotational molding aluminum mold should have better heat conductivity and save energy during the forming process. However, due to aluminum Due to strength reasons, the average thickness of the rotational molding aluminum mold is above 10mm. Therefore, the advantages that the rotational molding aluminum mold should have are greatly reduced. On the contrary, compared with the rotational molding steel plate mold, the rotational molding cycle is relatively longer. In addition, due to the increased thickness of the aluminum mold, the overall weight of the mold is relatively large, which puts a certain burden on the rotational molding machine. Furthermore, due to the characteristics of aluminum, the maintenance of rotational molding aluminum molds is a troublesome matter.
Compared with aluminum molds, its history is much later. It evolved from the automotive sheet metal mold process and the technology is not very mature. This is one of the reasons why rotational molding steel molds are not favored by industry insiders. Even so, rotational molding steel molds have many advantages that rotational molding aluminum molds do not have.
1. Price advantage: Except for small rotational molds, if medium-sized molds are made with steel plate molds, the mold cost can be saved by at least one-third.
2. Compared with aluminum moulds, steel plate formwork is easier to modify, repair and maintain.
3. Use steel plate mold. Since the wall thickness of the steel plate mold is only 2.5 or 3.0mm, the powder melting time will be shortened during the rotational molding process, which reduces energy consumption to a certain extent.
4. By combining traditional technology with CNC technology, precise rotational molds can be made. In the rotational molding industry, steel plate molds are still widely used. I think that with the development of rotational molding technology and the number of practitioners in the rotational molding industry, steel plate molds are still widely used. I think that with the development of rotational molding technology and the improvement of practitioners' understanding of rotational molding steel molds, the application of steel molds will usher in a new climax of demand.
