Troubleshooting PPSU Injection Molding
Troubleshooting PPSU Injection Molding: A Technical Guide to Mold Design and Tooling PPSU (Polyphenylsulfone) is a “problem-solver” material for high-heat and sterile environments, but it is also notoriously difficult to process. Many manufacturers face high scrap rates due to stress cracking, material degradation, and dimensional drift. As a precision mold maker in Shanghai, CNMOULDING has…
EDM Machining for Injection Molds
EDM Machining for Injection Molds: Solving Deep Ribs, Sharp Corners & Mirror Finishes In high-precision injection mold manufacturing, certain geometries cannot be achieved with traditional CNC milling—such as ultra-deep ribs, sharp internal corners, and high-gloss cavities. Electrical Discharge Machining (EDM) is the critical process that enables these complex features. At CNMOULDING’s Shanghai facility, we combine…
How to customize plastic products
How to Customize Plastic Products: A Practical Guide from Idea to Production Customizing a plastic product is a structured engineering process that extends beyond simple manufacturing. It involves a critical alignment of design feasibility, material physics, and tooling precision. In our 25+ years of experience in the Shanghai molding industry, we have found that the…
Types of Injection Molding Processes
Types of Injection Molding Processes Injection molding is not a single process. Depending on part design, function, and production requirements, different molding techniques are used to achieve the desired result. Understanding these process types helps engineers choose the right manufacturing method for cost, performance, and production efficiency. Standard Molding Standard injection molding is the most…
