Plastic Molding Design
Practical experience in selection of resin for several commonly used plastic injection
PVC: PVC is thermoplastic, generally divided into hard and soft, the difference is how much plasticizer is added to the raw material, less than 10% is hard and more than 30% is soft. Features: There is no obvious melting point, it becomes soft at 60 ℃, and it is viscoelastic at 100 ～ 150 [...]Top 3 Types of Plastic Forming Process
There are two types of plastics. One is called thermosetting resin which does not soften again once it is formed and hardened, and the other is called thermoplastic resin which becomes soft or hard when its temperature rises or falls. Although thermosetting resin has an older history, the majority of the presently used plastics are [...]Plastic Forming

This is to illustrate how to use tolerance analysis as a tool to ensure that a kitchen appliance molding design meets its mass production requirements and customer expectations for component assembly, product appearance, and product performance. The Benefits of Tolerance Analysis Before mass production Verifies a design will achieve the desired level of quality Ensures [...]Injection Molding Moldflow Case Analysis Report
Project Summary 1, Analyze Intention To search best gate location To predict flow issues 2, Input Model Description Tentative runner system and cooling Circuits are build for calculation 3, Result Required Filling result (flow, pressure drop, deflection and so on.) Analysis on geometrical deformations Wall Thickness Analysis: That photo mean wall thickness is about 2.50mm [...]Shrinkage and warpage in the molding desing
Shrinkage and warpage Why do they occur? Shrinkage is inherent in the injection molding process. Shrinkage occurs because the density of polymer varies from the processing temperature to the ambient temperature. During injection molding, the variation in shrinkage both globally and through the cross section of a part creates internal stresses. These so-called residual […]
How to Design a Small Household Appliance Plastic Parts
The process of plastic injection molding is designed to produce precision parts at a low cost. The part design must be developed to maximize the efficiency inherent in high-volume molding. With the right design, parts can be made consistently and with quality. Without a good design, costly processing mistakes can be made. Plastic Injection Molding: Part Design […]
Determining the Cost of a Plastic Injection Mold
One of the most common questions for those looking to source a plastic injection molder is “How much will a plastic injection mold cost?” It’s one of the most important questions, since the actual mold represents the most significant expense in upfront production costs. That being said, many factors go into determining the full cost. […]
