How to choose the vertical injection molding machine, because the vertical mold clamping vertical injection, the upper mold movable lower mold fixed. Straight-line injection molding machine is the most optimized solution for insert injection molding. The following are related to the purchase and classification of vertical injection molding machines.
The most basic four elements of the injection molding machine are as follows: 1. The modulus of the mold, which is the length*width*h of the mold, selects the specific specifications suitable for the mold of the factory product and is slightly larger than the mold, which is the effective spacing in the Corinthian column; The amount of injection is generally calculated as PS of plastic material in ounces (oz). Since the PS density ratio is a vertical centimeter specific gravity of 1.05g, this is the conventional calculation unit. Different plastics have different structural density ratios, so the net weight of the product should be selected. The most effective injection volume of the injection molding machine is not more than 80% and not less than 20%, which is suitable for the model. 3. Product accuracy, accurate plastic products Degree is directly related to the purchase and configuration requirements of the machine. For example, engineering plastics must use alloy screw and material tube. The length-to-diameter ratio of screw is more than 20 times, in order to achieve good plasticization standards and requirements. The precision requirements of the product may be selected by specific pressure + specific flow or semi-closed loop or full closed loop oil control; Fourth, the clamping force is the most important part of the injection molding surface, and the clamping force is expressed in units of tons. (T), the standard of the clamping force is selected to be the length*width of the plastic product*.
Classification of vertical injection molding machines: Vertical injection molding machines can be divided into the following categories.
First, the vertical injection molding machine series: This model is mainly for the injection line, all kinds of electronics, computer data lines and power plug wire injection molding, injection molding products are not required to meet the high precision standards, generally PVC, PE and other plastic materials injection molding As the mainstay, the specific applicable model specifications for this product generally range from 15T to 35T. Due to the specific modulus and configuration of each manufacturer's model, the manufacturer must be required before purchase. The factory determines the specific parameter specifications of the model.
Second, the vertical horizontal injection molding machine, C-type injection molding machine series: the machine vertical mold clamping, horizontal injection rubber because there is no guide column, because the mold clamping part into an English letter "C" named. The machine is complex in structure and has a large amount of injection glue. Due to the wide working area of ​​the non-guide column, it is mainly suitable for injection molding of various types of safety power plugs, such as French head, American plug, British plug and so on.
Third, vertical single slide type injection molding machine, 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, and it is also optimized for insert injection molding. One of the molding schemes. Because the machine has the upper mold fixed, the lower mold slides out. The double slide type has an upper mold double lower mold, and the two molds alternate work, which is suitable for embedding or removing precision hardware. General molded products, such as electronic precision connectors, mobile phone connectors, integrated circuit components, etc.
Fourth, vertical disc injection molding machine, rotary series: vertical disc injection molding machine rotary series can be described as the optimal solution for precision parts embedded injection molding, because the machine can design an upper mold two lower mold or multiple lower mold The function is more suitable for complex embedding and manual saving.

Ph orp controllers are widely used in thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food and tap water industries. With a suitable pH sensor or orp sensor, the pH value or ORP value and temperature in the solution can be continuously monitored. Daruifuno's pH ORP controller has 2 channels of 0/4-20mA current output, supports signal remote transmission and long-term calibration, and also has a two-wire RS485 interface, which can be easily connected to the computer through the MODBUS-RTU protocol for monitoring and recording .
As an online dosing control pH meter, the control function is very important. Our controllers are equipped with 2 relays that can be set by SPST. Customers can set the opening value and closing value to realize the control of the acid-base dosing pump, temperature and cleaning control.
For the convenience of customers, the small-sized pH controller also adds a quick calibration button. The calibration of the pH ORP controller is also very important. It is usually recommended that the electrode needs to be calibrated every 7 days. Our ph meter transmitter supports pH three-point calibration , ORP two-point calibration, and the calibration point can be set by yourself.
In addition, we also have the solution ground ph meter, which can be connected with the SG sensors, used for power plant pure water.
Such a multifunctional pH ORP controller has a very favorable price. We have many models to meet different needs and save costs for customers.
