Matériaux et paramètres structurels de la vis et du fourreau de la machine à film soufflé
The screw of a blown film extruder is the core component of the extrusion system, and its structure directly affects plasticizing quality, extrusion stability, and film uniformity. A typical blown film extruder screw uses a single-screw design, divided into three functional zones: the feeding zone, the compression zone, and the homogenizing zone. These three zones work together to achieve solid conveying, melt plasticizing, and pressure equalization output. Feeding Zone: Located…
Comment réduire le degré d'usure de la vis de la machine de moulage par injection
The injection screw is the core component of the injection molding machine, and the screw is operated under high temperature, high pressure, high mechanical torque and high friction environment for a long time, and the wear problem is inevitable. Generally, the screw has been surface nitrided to increase the surface hardness, that is, Improve anti-wear ability. However, if the cause of wear is neglected, and the wear is not reduced…
Voici quelques défaillances de production courantes des presses de moulage par soufflage : * **Problèmes de chauffe :** le plastique n'est pas chauffé à la bonne température, ce qui entraîne des pièces fines ou des défauts de moulage. * **Problèmes de pression :** la pression d'air n'est pas correcte, ce qui peut provoquer des bulles, des parois minces ou des pièces déformées. * **Problèmes de refroidissement :** le refroidissement n'est pas uniforme ou adéquat, ce qui peut entraîner des pièces qui se déforment ou qui ne se démoulent pas correctement. * **Problèmes de moule :** les moules peuvent être usés, endommagés ou mal alignés, entraînant des défauts dans les pièces produites. * **Problèmes de matière première :** la qualité du plastique utilisé peut affecter le résultat final. Des impuretés ou une mauvaise qualité peuvent causer des défauts. * **Problèmes d'automatisation/contrôle :** les systèmes de contrôle défectueux ou les erreurs de programmation peuvent entraîner des cycles de production incohérents et des pièces défectueuses. * **Usure de l'équipement :** les pièces de la machine, comme les vis, les barres de chauffage ou les systèmes de commande, peuvent s'user avec le temps, nécessitant un entretien ou un remplacement. * **Accidents et erreurs humaines :** des erreurs d'opération, un mauvais réglage ou des accidents peuvent endommager la machine ou les pièces en production.

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…
