Explanation of the fine grinding process in screw refurbishment

The outer diameter of the screw is easy to be roughly ground flat, so one of the most commonly used methods for refurbishing screws is the fine grinding process. Fine grinding is also known as fine grinding. It is an important process between the two major processes of rough grinding and polishing. The purpose of fine grinding is to ensure that the workpiece achieves the required surface shape accuracy, dimensional accuracy and surface roughness before polishing. Therefore, the quality of fine grinding has a very significant impact on polishing. The methods of fine grinding are divided into...

Strength analysis of injection molding machine screws

An injection molding machine injects molten plastic into a mold, and after cooling, it becomes the product. It has a very wide range of uses. Depending on the type of plastic, it is used in different places. Injection molding machines are the most widely used processing machinery in the plastic processing industry. Not only can a large number of products be directly produced by injection molding machines, but they are also the key equipment that constitutes the injection stretch blow molding process.

Extrusion screw wear and protection

When extruding thermoplastic composites, the design of the screw and the structure of the screw and barrel are of vital importance. If these issues are considered in advance. This will ensure the successful completion of the processing of thermoplastic composites. Generally, the design of screws for thermoplastic composites mainly involves two different aspects. One is the mixing of materials; The second is the processing of thermoplastic composites.

Introduction to Methods for Preventing Slippage of Injection Molding Screws

When the injection molding screw has difficulty pressing the material at the feeding port or fails to form sufficient adhesion along the length of the barrel to convey the material, the screw will slip. During the pre-plasticizing stage of the screw, as the screw rotates in the barrel, conveying the material along the screw direction and retreating to accumulate the material for the next injection molding, the screw...

Plastic plasticizing screws are classified into three sections according to their geometric shapes:

1. Feeding zone: The depth of the fixed screw groove is determined, and its function is to be responsible for preheating, solid plastic conveying and pushing. It is necessary to ensure that the plastic begins to melt at the end of the feeding section - that is, it needs to be preheated to the melting point.

How can the wear of screw barrels be reduced and their usage improved

The screw barrel of an injection molding machine operates for a long time under high pressure, high temperature, high mechanical torque and high friction conditions. The first few factors are required by the process conditions, but the wear and tear caused by friction is inevitable. Generally, screws undergo surface nitriding treatment to enhance surface hardness, that is, to improve wear resistance...
