How to distinguish between single-mode die and continuous die
- 2020-03-27-

At present, there are many mold manufacturing companies on the market, and there are many types of molds. How to judge the quality and accuracy of molds requires manufacturers to have enough production to meet market demand. In the production process, scientific operations are required to make The quality and precision of the products meet customer requirements. According to the steps of the process, the mold can be divided into single-order mold and continuous mold. Do you know the difference between the two?

The single-order die refers to a die that can complete only one stamping process in one stroke of stamping. After this project is completed, the product needs to be taken out of the mold manually or with a mechanical hand, and then placed in the next stop of the mold to continue production. Until the last process of the mold is completed, the entire product is considered completed. This kind of mold can be punched separately when there are few machines and the tonnage of the machine is not enough. Maintenance is also simple, but it is time-consuming and laborious to produce, requires more labor and time costs, and has a higher scrap rate. Therefore, the single-process mold is generally suitable for the development stage of new products, because the manufacturing cost is lower than the general continuous mold, the processing is convenient, the manufacturing cycle is short, and the product can be produced in a short time. Because of the low production cost and simple maintenance, this type of mold is also very suitable for small batch products. However, after a certain number of products are reached, the single-sequence die cannot fully meet the increasing number. The proportion of machine tools and labor is relatively large, and the production cost is low and the efficiency is low. The above are the advantages and disadvantages of single-sequence mode.

Continuous molds are divided into ordinary continuous molds and progressive continuous molds. Ordinary continuous mold means that except for blanking, the rest of the molds have at least two procedures. The products produced by this mold are generally completed by more than two machine tools (each machine tool can be operated manually or by manipulator). Compared with single-sequence molds, ordinary continuous molds have the advantages of time-saving, machine-saving, and labor-saving. The disadvantage is that the mold maintenance is more troublesome; progressive continuous molds mean that all the processes are completed on a pair of molds, usually during stamping. In one stroke of the trip, the molds for all stamping processes are completed at different stations at the same time (generally such molds are equipped with a feeder). The advantages and disadvantages of this mold are very obvious. The advantages are: more labor-saving than ordinary continuous mold, labor, machine tool, product scrap rate is less, and the efficiency is higher. Disadvantages: It is difficult to make molds, the cost is relatively high, and the maintenance is more difficult. It is suitable for parts with low difficulty and large output. In summary, both ordinary and progressive continuous modes have an advantage and high efficiency. All have a disadvantage, the mold maintenance is not convenient. The type of mold can only be positioned according to your needs.

If you need to choose between the two, I still feel that each has its own benefits. The product quality of single-process mold production is high and the production efficiency is low. Although the continuous mold has high production efficiency, the quality of the product is unstable. Of course, continuous mode is better. Secondly, we also need to look at the quantity requirements of the product. If it is a large batch, it is recommended to use a continuous mold. Let's take a look at the structure of the product again. Some products are designed for continuous molds that are relatively expensive or unsuitable for continuous molds. We need to consider this comprehensively.

The above is the introduction of the difference between single-order molds and continuous molds. I hope it will be helpful for you to buy molds.
