The way the mold selects the chiller
Chiller is important for mold.In fact, a mold is a heat exchanger. The heat is first transferred from the molten plastic to the mold, and then from the mold to the continuously circulating cooling medium-ice water. Only a small part of it enters the air and the pressure of the injection molding machine. template. As we all know, a considerable part …
Air-cooled chiller inspection method
Generally, after using the air-cooled chiller for a long period of time, some problems cannot be avoided. If there is a failure, we should carefully check the operating conditions of the various parts of the injection machine. The main points are to check the refrigeration system, electrical system, air system, and water system. To judge whether their homework is normal, the editor …
Mold common problems
Raw edges a) Confirm whether the number of frames and clamping forceof the injection machine are sufficient b) Confirm whether the pressure is too high 1) If the unsaturated sample still has burrs, it means that the mold clamping is not good or the fault is broken. 2) If the mold clamping is not good and the size is too …

injection machine purchasing attention (1)
The five major hazards of excessive temperature rise of the injection molding machine are: thermal deformation of the machine, reduced oil viscosity, deformation of rubber seals, accelerated oil oxidation and deterioration, and reduced air component pressure. One of the hazards: thermal deformation of the machine The moving parts with different coefficients of thermal expansion in the hydraulic components are stuck …
injection machine purchasing attention appointments (2)
The correct selection of the type and specifications of the injection machine before use has a greater impact on the production cost, quality and production efficiency of injection molded products. Before selecting the specifications and models of the injection molding machine, first check the performance parameter values ​​of the injection molding machine in the product instruction manual provided by the …
Cost control of injection molding machine workshop-eight ways to save money
For an injection molding factory, the energy consumption of the injection molding process accounts for about 60%. Therefore, effectively reducing the energy consumption of the injection molding machine is an important way to save energy in the injection molding factory. With the continuous improvement of the energy-saving technology of the injection molding machine itself, reducing the overall energy consumption of …
Safety operation rules of china injection molding machine!
1. Preparations before starting the china injection molding machine 1. Wear the safety protective clothing prescribed by the workshop before starting production. 2. Clean up the environment around the equipment, and don’t store anything unrelated to production. 3. Clean up the debris inside and outside the workbench and equipment, wipe the injection seat guide rail and the tie rod of …
What is the principle, characteristics, application and process of injection molding by injection molding machine?
Today let us talk about the principle, characteristics, application and process of injection molding by injection molding machine. 1. The principle of injection molding. Add granular or powdered plastic into the hopper of the injection machine. The plastic is heated and melted in the injection machine to keep it flowing, and then injected into a closed mold under a certain …
There are always problems with the injection part of the injection molding machine, how to solve it
There are always problems with the injection part of the injection molding machine, how to solve it? 1. Cannot shoot glue Approach: 1) The nozzle is blocked by foreign matter. Check whether the nozzle is blocked, clean or replace the nozzle. 2) The glue nozzle is broken. Disassemble the flange to check whether the glue nozzle is broken, and replace …
how to choose injection molding machine
There are two templates on the injection molding machine, one is not moving, called the fixed template; the other can be moved, called the moving template. The mold is fixed on the two templates by screws and pressing plates respectively. When the mold is opened, the movable template of the injection molding machine moves, thereby driving the mold to open. …
Injection molding machine knowledge
Anyone who can adjust the machine knows the five elements of injection molding, but on whom are these five elements built? The most important thing is the injection molding machine. Of course, there are also some auxiliary equipment (such as mold temperature controller, temperature control box, etc.) to help complete it. So how much can you know about the performance …
