canon de vis de machine de moulage par injection
Vous apprendrez à sélectionner et à vérifier la précision et la stabilité des machines de moulage par injection ?
As one of the pillar industries of light industry, the injection molding industry has penetrated into all aspects of life. As the main equipment for injection molding production, injection molding machines coexist with high, medium and low grades, with a wide range of types and endless application types. Even many professionals in the injection molding processing industry are dazzled and it is difficult to choose the injection molding machine that…
Quelle est la cause du glissement de la vis d'injection ?
For hygroscopic materials (such as nylon), the high water content of the resin can also cause the screw to slip. Improper drying will significantly reduce the viscosity of the material and generate water vapor in the drum, resulting in a reduction in the conveying capacity of the screw. In fact, there are many reasons for slippage, which may be related to high back pressure, overheating or overcooling of the end…
Quels sont les avantages de l'utilisation d'une vis à double canon dans une machine de moulage par injection ?
What are the application advantages of cone twin barrel screw in injection molding machine It can be seen from the extrusion process that the injection screw barrel is operated under high temperature, certain corrosion, strong wear and large torque. Therefore, the conical twin-barrel screw must meet high temperature resistance and not deform under high temperature; wear resistance Long life; corrosion resistance, material is corrosive; high strength, can accept high torque,…
Quel type de vis convient aux fabricants de moules à injection ?
Commonly used screws in the market are No. 45 steel, 40cr steel (chrome plated), and 38CrMoAlA nitrided steel. If your product is +glass fiber. When using chrome plating, it will slowly fall off after about 3 months, and the color difference will appear. Nitriding is best. Stainless steel screw cannot be made of glass fiber. Generally, ordinary screws are used for nonspecial materials. Such as PC\PMMA\PA and other materials. barrel…
Que savez-vous des causes de l'usure des vis d'extrusion ?
Each plastic has an ideal plasticizing temperature range, and the extruder screw barrel processing temperature should be controlled to make it close to this temperature range. Granular plastic enters the barrel from the hopper and first reaches the feeding section. Dry friction will inevitably occur in the feeding section. When these plastics are not heated enough and melted unevenly, it is easy to increase the abrasion of the inner wall…
Comment distinguer et appliquer correctement la vis de la machine de moulage par injection ?
The screw is an important component of the injection molding machine. In the production, the screw is responsible for conveying, compacting, melting, stirring and applying pressure to the plastic. The screw required by the injection molding machine can be divided into three types: gradient type, mutation type, and universal type. These three types of screws have their own shapes and functions. The gradual screw is mainly used to process non-crystalline…
Comment utiliser le canon à vis de manière innovante ?
After the screw barrel is used for a period of time, the screw edge and the nitriding layer of the barrel (when making a new screw, both the screw and barrel will stop the nitriding heat treatment, so there will be about 30-60 silk oxide layers on the surface 2) when worn in both directions, the gap between the two sides increases, causing partial backflow of the plastic, and the…
Quels sont les détails auxquels il faut prêter attention pour les trois petits morceaux de vis ?
The three small pieces of screw head play the functions of sealing, mixing, plasticizing and other functions in the entire screw group. It is a relatively important part. The quality problems of many plastic products are closely related to the three small pieces of screw head. There are often many three Failure to deal with the details of small parts has greatly increased the scrap rate of plastic products, and…
Comment résoudre le problème de la déformation par flexion dans le processus d'extrusion des produits ?
The bending deformation of PVC profile is a common problem in the extrusion process. The main reasons are: uneven discharge of the die; insufficient cooling of the material during cooling and shaping, and inconsistent shrinkage; equipment and other factors.It is recommended to solve from the following aspects:1. Ensure the concentricity and levelness of the entire extruder line, and correct the concentricity and levelness of the extruder, die, shaping die, water…
Quelles sont les méthodes de nettoyage de la vis d'extrusion ?
The working condition of the extruder that needs to clean the screw is generally to change the color or restart after the machine has black spots. There are two common methods: one is to wash with raw materials or nozzle materials, and the other is to directly pull the screw for polishing and cleaning.The method of drawing the screw affects the precision of the equipment. Pulling the screw for a…
Comment réduire le taux de défaillance de la machine de moulage par injection ?
When the injection molding machine is working, the injection molding machine parts are like the wheels of a motor vehicle. As long as they are started, they will be subjected to pressure, impact, friction, and extrusion. For the same tire, driving on a flat road and a skilled driver can often prolong the service life of the tire.dAnd when driving on uneven roads with lots of sand and gravel, coupled…
Quels sont les points à prendre en compte lors de l'utilisation de la vis d'une machine de moulage par injection ?
The screw barrel of the injection molding machine often sticks to the material, which not only affects the progress but also affects the quality of the product, and it is also troublesome in the process of troubleshooting. Different plastics are due to their melting speed, heat absorbed during melting, melt viscosity, and water absorption The difference in characteristics such as rate, thermal stability, etc., is very different for the shape…
