When a plastic or metal specimen with a rectangular cross‑section is bent between your fingers, one surface is stretched under tension while the opposite surface is compressed, as shown in Figure 1. ...
Hardness is a measure of a solid material's ability to resist permanent deformation when subjected to a compressive force. Hardness varies significantly between different materials — metals, for ...
In the mold manufacturing industry, trial molding and acceptance are essential steps to verify the stability, reliability, surface quality, and production efficiency of an injection mold. Today, we wi...
A mold file records every critical stage of a mold's life — from design and manufacturing to maintenance and eventual retirement. Without proper documentation, quality becomes impossible to trace...
Dimensional inspection ensures plastic parts meet the required specifications. Below are the key aspects of this process.1. General Dimensional Inspection MethodParts used for dimensional measurement ...
When we talk about the appearance of a plastic part, we mean things like its shape, color, gloss, and surface quality — basically, everything you can see and feel with your eyes.Different parts have ...
In injection molded parts, the state of internal stress varies across different regions, and the degree of part deformation is largely determined by the distribution of these stresses. The presence of...
In modern product design, plastic products are playing an increasingly vital role within overall product structures. Injection molded components, in particular, are being widely used not only as struc...
When a product completes production and readies for delivery, it stands at the final gateway before reaching the customer—this is where Outgoing Quality Control (OQC) takes center stage. As the last ...
In the final stage of manufacturing, Finished Quality Control (FQC) serves as the critical "last line of defense" to safeguard product quality before goods enter warehouse storage or reach c...
