Vertical injection molding machine classification, good choice makes entrepreneurship easier
2023 / 02 / 07
Vertical injection molding machine classification, good choice makes entrepreneurship easier Industrial production and processing has always been a relatively traditional and mature industry. For this reason, many entrepreneurs believe that there is no future in this industry. In fact, we can see from the current data that the demand for plastic products in the market is still in short supply, and there is still a very large market demand gap in industrial production, especially in the plastic product processing industry. Choosing this direction as an entrepreneurial project can definitely bring us different experiences, but for the processing of plastic products, how do we choose the categories of vertical injection molding machines? The classification of vertical injection molding machines is mainly based on the overall use and appearance. In terms of the type of use, Zhuji is mainly divided into single-material and double-material injection molding machines. Mainly aiming at the different needs of different products, the single-material standard injection molding machine is mostly applicable to the production and processing of some common single-color and single-material plastic products. The double material is for the processing of multi-color products with relatively high requirements and relatively novel design. According to the overall shape, there are several categories of vertical injection molding machines, such as disc type, standard type, single slide plate, etc. When selecting, this classification mode is mainly based on the size of the floor area and investment cost. If the investment in the process of entrepreneurship is small and the cost is low, priority should be given to those small injection molding machines,
