Hot runner mold trial 8 steps Step 1. Set the temperature of the bucket It should be noted that the initial barrel temperature setting must be based on the recommendation of the material supplier. This is because different manufacturers and brands o
About Hot Runner Mold -Development History The production of hot runner molds is extremely active in industrialized countries and regions around the world. The proportion of hot runner molds is constantly increasing. Many small mold fact
一、 Advantages of a hot runner system: 1. Saving plastic raw materials: In pure hot runner molds, there is no production waste due to the absence of a cold runner. This is particularly significant for expensive plastic application projects. In fact, the
Plastic forming is the process of making various forms of plastic (powder, particle, solution, and dispersion) into products or blanks of the desired shape. There are over thirty methods of forming. The choice of plastic molding mainly depends on the t
Mold manufacturing is a complex process that involves steps such as design, processing, assembly, debugging, and ultimately putting it into use. Throughout the entire lifecycle, there are 10 fundamental factors that pose a threat to the quality of plastic
What is the reason why the heat splitter plate cannot reach the set temperature? Analysis of reasons: Poor or ineffective contact of thermocouples, short circuit of heating wires, and loose or short wiring of heating wires. Handling: Check if the th
1. Plastic mold - large water mouth mold: A large water mouth mold is a mold where the gate and runner are on the parting line, and it is demolded together with the product during mold opening. The design is the simplest, easy to process, and the cost is
Runner is the basic form of injection molding! The so-called cold runner is a conventional injection mold, and after injection molding, there is condensate in the runner that needs to be removed!With the reduction of resources and market competition, the
Due to the fact that the hot runner does not generate "garbage", there is no problem of handling "garbage". 'Garbage' means a waste of resources, while hot runner systems are low-carbon products that do not produce harmful envi
1、 When selecting an injection molding machine, the following factors need to be considered:1,Hot runner moldDue to the increase inHot runnerDue to the addition of a runner plate, the thickness of the mold increases accordingly. When selecting an injectio
The hot runner injection mold is the most common type of non runner solidification injection mold. The existence of coagulants in the pouring system not only wastes raw materials and increases the energy consumption of the injection machine, but also incr
The opening and closing of the valve needle is controlled by the injection signal of the injection molding machine. Gate opening - The injection signal is transmitted to the electromagnetic valve of the nozzle, which controls the intake channel of the cyl
Hot runner injection method 1: "point gate". The point gate method is the most common injection method, which is determined by several factors such as gate size, gate cooling, and the temperature of the nozzle tip. It is suitable for almost all
1. Material discoloration, coking, or degradation Main reasons: Improper temperature control; The small size of the runner or gate causes significant shear heat generation; The dead center in the flow channel leads to prolonged heating of the trappe
The customer may not have been very careful about the application of the hot runner system. Today, Haochen Hot Runner told you that when selecting a hot runner system, the injection pressure should be considered. The injection pressure loss in the hot
1. Briefly describe the working status of check valves during plasticization, injection, and pressure maintaining processes; Plasticization: On; Injection molding: closed; Pressure maintaining: closed; 2. Briefly describe the relationship
In most cases,hot runner systemThe leakage of materials is not caused by poor design, but by failure to operate according to design parameters. Usually, leakage occurs at the sealing point between the hot nozzle and the splitter plate. According to the de
1、 Fill in the blank question:(1 point per question, a total of 20 points) 1. The viscosity of ABS and PP materials is sensitive to shear rate (injection rate), but not to material temperature. Increasing material temperature has no significant effect
The hot runner temperature control box, also known as the hot runner temperature controller, is a device that continuously maintains the required temperature value of the hot runner system. It is composed of a temperature control card, air switch, box, fa
Hot runnerThe invention and application of has brought more development opportunities for mold manufacturers; From general-purpose plastics such as polypropylene and polyethylene, to engineering plastics such as polycarbonate and glass fiber reinforced ny
