According to the cooling method, industrial chillers can be roughly divided into two types: water-cooled chillers and air-cooled chillers. Do you have a grasp of these two cooling methods? Here is the detailed explanation of flyse machinery: Refrigeration method of water-cooled chiller: (1) Choose Oumei refrigeration compressor, high EER value, low noise, low energy consumption, energy saving, stable operation. (2) …

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 …

As we all know, chillers are widely used, and one of them is the cooling of plastic molds. Basically, most plastic mold production plants are indispensable for the chiller, so today the flyse will introduce to you in detail. How to choose a suitable chiller in the production of molds. In addition, since injection molding machines are often used together with chillers, …

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 …

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 …

Anyone who wants to buy an injection molding machine will encounter this problem. When buying an injection molding machine, mold,auxiliary machine should I buy a large or a small one? Should I buy a cheaper or more expensive one? Thousands of dollars, while the expensive ones cost hundreds of thousands or even millions; some injection molding machines are too large to fit, …

injection molding conditions is the important thing for workshop owner to master. Injection molding is an industry with a wide range of knowledge, technology and practice. Plastic raw materials, toners, nozzle materials, molds, injection molding machines, peripheral equipment, fixtures, sprays, various auxiliary materials and packaging materials are used in the injection molding production process, which brings a lot of work to the management …

In the injection molding process of plastics, thermoplastics, due to the volume change caused by crystallization, strong internal stress, large residual stress frozen in the plastic part, strong molecular orientation and other factors, so compared with thermoset plastics, the shrinkage rate is larger. The shrinkage rate is wide and the directionality is obvious. In addition, the shrinkage after molding, annealing or humidity …

Injection molding machine basic structure is really important for businessman. According to the requirements of the injection molding process, the injection molding machine is a model with strong mechatronics. It is mainly composed of injection parts, clamping parts, fuselage, hydraulic system, heating system, control system, feeding device, etc. At present, common ear injection devices have single-cylinder type and double-cylinder type. …

One, analysis of the reasons for the fracture of the tie rod of the injection molding machine Fatigue failure. The working process of the injection molding machine is a process of alternating stress, so any factor that causes stress concentration may lead to fatigue failure. like: The step where the shaft diameter changes greatly. Lack of rounded corners, undercuts, etc. at …

The screw fracture temperature is also related, but it is rare, almost all of the screw itself is of poor toughness, or the screw has been used for a long time, refurbish the screw! The injection molding materials are rough. For example, adding GF [glass fiber] to the injection molding materials is the most expensive screw and machine! This injection molding material has poor …

Acrylic is chemically called polymethyl methacrylate (PMMA in English). Due to the shortcomings of PMMA surface hardness, easy scratching, low impact resistance, poor molding fluidity, etc., the modification of PMMA has appeared one after another. Such as the copolymerization of methyl methacrylate with styrene and butadiene, the blending of PMMA and PC, etc. The flow of PMMA is worse than that …
