Due to the tendency of thin-walled plastic molds to avoid ordinary plastic molds in terms of wall thickness, the processing characteristics of thin-walled plastic molds are also quite unique. What conditions can be met to be considered qualified thin-walled plastic molds? It can be analyzed from aspects such as structure and performance. Let's take a closer look below.
Due to the high injection pressure required for thin-walled injection molding, the stiffness and strength of thin-walled plastic molds are required to withstand greater pressure. When processing thin-walled plastic molds, thicker patterns and more supporting columns are often used.
Compared with ordinary plastic products, thin-walled injection molded plastic parts have lower residual stress and often have issues such as warping and deformation. In order to avoid similar defects, it is necessary to strengthen the cooling during the processing of thin-walled plastic molds to ensure the dimensional stability of plastic parts.
Due to the high requirements for plastic thin-walled materials, a large door is used, and the thickness of the door is greater than that of the wall. For this reason, thin-walled plastic molds are commonly used in non flow gating systems to ensure the balance of the mold pouring system.
It is understood that the filling time of thin-walled injection molding is shorter than that of normal injection molding, indicating that its injection speed is faster. In order to prevent trapped gas ignition during this process, higher requirements for exhaust performance have been put forward in the processing of thin-walled plastic molds to meet the demand for rapid exhaust.
In addition, due to the thinner wall thickness of thin-walled plastic parts compared to ordinary plastic parts, they are more prone to damage. So, in the ejection process of thin-walled plastic mold processing, there is a higher demand for the ejection system in order to achieve a better balance as much as possible.
