Silicone rubber, with its ability to stretch at -60°C and maintain stability at 250°C, is known as the "all-purpose adhesive for manufacturing." It is used in various industries, including automotive, electronics, and medical.

In plastic injection molding, the "gate size design" directly affects the product's flowability, cooling efficiency, and quality stability. This article will analyze how gate size influences volumetric flow rate and shear rate, and will provide examples and calculations.

With the trend of product miniaturization, micro-components are playing an increasingly important role in our lives, from connectors in smartphones and stethoscope components in medical devices to precision parts in fiber optic communication equipment.

At this stage, we need to estimate the "mold manufacturing costs," "plastic material usage per mold," and "production capacity." We make these estimates through two steps: "parting line design" and "cavity layout."

The first step in evaluating a product's mold is selecting the gating system. The gating type will determine the subsequent mold type, layout, runner design, and mold opening method, among other things. What is gating? Gating refers to...

In plastic injection molding, if a side-entry gate type is used, a post-processing step of shearing the gate is necessary to separate the finished product from the runner. There are many ways to shear the gate, the most basic being manual breaking.
