In simple terms, when the wall thickness is less than 1mm, it is called thin-wall. More generally, the definition of thin-wall is related to the flow/wall thickness ratio, the viscosity of the plastic and the heat transfer coefficient.The process flow L from the main flow of the thin-wall injection
Maintenance work requires understanding of equipment operation methods and having some basic knowledge of injection molding, as well as being able to use injection molding machines correctly. If you don't know how to operate the injection molding machine, maintenance work is very difficult, and diag
The pressure of the molten material after entering the mold cavity is quite high, which increases the density of the molten material. Therefore, the greater the pressure inside the cavity, the smaller the shrinkage after molding. The shrinkage rate of amorphous and crystalline plastics decreases
Dents are caused by local internal shrinkage after gate sealing or injection of missing material. The indentation or micro indentation on the surface of injection molded products is an old problem in the injection molding process. Dents are generally caused by an increase in the local shrinkage rate
The effect of increasing back pressureIn order to obtain high-quality adhesive, the plastic needs to be uniformly heated or melted and thoroughly mixed. Using the correct screw is necessary for proper melting and mixing, and there is sufficient pressure (or back pressure) in the feeding cylinder
What materials are commonly used for mold blanks? Answer: 45 # steel is commonly used for mold blanks.What is the difference between working in CAD drawing model space and layout space? Answer: Model space is the space for graphic entities, while layout space is the space for drawing layouts.3. What
The mold main channel, also known as the main runner or shaft runner, refers to the flow channel from the part of the extruder nozzle in contact with the main mold runner bushing to the diverter channel, which is the first part of the molten plastic after entering the mold.
