Selection of Vertical Injection Moulding Machine

How to choose a vertical injection moulding machine, because the vertical mold clamping and vertical injection, the upper mold is movable and the lower mold is fixed. Straight injection molding machine is the most optimal solution for injection molding of embedded parts. The most basic four elements of injection molding machine are selected:

1. Modulus of modulus, which is the length*width*height of the mold, choose the specific specifications suitable for the factory product mold and slightly larger than the mold, which is the effective spacing within the Corinthian column;

2. The injection quantity is generally calculated by the plastic material PS, and the unit is ounce (oz), because the PS density ratio is a vertical centimeter and the specific gravity is 1.05g, which is the conventional calculation unit. Different plastics have different structural density ratios, so it is necessary to choose the product’s net weight water inlet compared with the most effective injection volume of the injection molding machine. It is not more than 80% and not less than 20% for the suitable model;

3. Product accuracy says that the accuracy of plastic products is directly related to the purchase and configuration requirements of the machine. For example, engineering plastics must use alloy screws and feed tubes, and the screw L/D ratio is more than 20 times. In order to achieve good plasticization standards and requirements. According to the precise requirements of the product, specific pressure + specific flow or semi-closed-loop or full-closed oil circuit control can be selected;

4. The clamping force is the most important part of the injection surface, and the clamping force is expressed in units of tons (T), the standard for choosing the clamping force is the length * width * of the plastic product and the internal resistance of different plastics.

Classification of vertical injection moulding machine: vertical injection molding machine can be divided into the following categories

1. Vertical injection moulding machine series: This model is mainly used for injection molding of connection lines, various types of electronics, computer data lines, and power plug lines. The precision standards of injection products are not high. Generally, plastic injection materials such as PVC and PE are used for injection molding. As the dominant, the specific applicable model specifications suitable for this product generally have a clamping force ranging from 15T to 35T. Due to the different specific modulus and configuration of each manufacturer’s model, the manufacturer must be asked before purchasing. The factory determines the specific parameters and specifications of the model.

2. Vertical and horizontal injection molding machine, C-type injection molding machine series: the machine’s vertical mold clamping, horizontal injection molding because there is no guide column, because the mold clamping part into an English letter “C” is named. The machine has a complicated structure and a large injection volume. Due to the wide operation area of the guide column, it is mainly suitable for injection molding of various safety power plugs, such as French heads, American plugs, and British plugs.

3. Vertical single-slide-type injection molding machine and double-slide-type injection molding machine series: This machine is mainly for engineering plastics. The products have strict precision requirements. Precision or small inserts are injection molded together, which is also the most optimized for injection molding of inserts. One of the molding programs. Because the machine has the function of fixing the upper mold and sliding the lower mold. The double slide plate type has an upper mold and a lower mold, and the two molds are alternately operated, which is more suitable for inserting or removing precision hardware. General shaped products, such as electronic precision connectors, mobile phone connectors, integrated circuit components, etc.

4. Vertical disc injection molding machine, rotary series: The vertical disc injection molding machine rotary series can be said to be the most optimal solution for embedded injection molding of precision parts, because the machine can design one upper die two lower die or multiple lower die Function, compared with the advantages of complex embedding and labor saving
