How to properly design ribs and bosses in plastic parts?
How to properly design ribs and bosses in plastic parts? Ribs and bosses are essential features in plastic part design. They add strength, support, and help with assembly — but if not designed correctly, they can lead to cosmetic defects, weak joints, and mold complications. This article explains: What ribs and bosses are used for […]
What’s the minimum draft angle needed for injection molded parts？
One of the most overlooked — yet critically important — aspects of plastic part design is draft angle. If your part doesn’t have enough draft, it can stick to the mold, cause damage during ejection, or increase tooling wear and cost. This article explains: What a draft angle is Recommended draft angles for different surfaces What […]
What Is the Best Wall Thickness for Injection Molded Plastic Parts?
When designing plastic parts for injection molding, one of the most critical decisions a mechanical engineer must make is choosing the right wall thickness. Wall thickness affects part strength, manufacturability, cycle time, and cost — and poor choices often lead to defects like warping, sink marks, or short shots. In this article, we’ll cover: – Recommended wall thickness ranges by […]
How to eliminate the shrink marks?
How to eliminate the shrink marks? What are shrink marks in Injection Molding？ Shrink marks (also known as sink marks) are small, shallow depressions or dimples that appear on the surface of an injection-molded plastic part. They are not cracks or holes, but subtle surface defects caused by uneven cooling and material shrinkage during the molding process. These marks can […]
SPI Plastic Mold Finishing Standard
The Society of the Plastics Industry (SPI), now known as the Plastics Industry Association, established a standard for mold polishing and finishing that is widely recognized in the plastics industry. GoodTech MFG uses SPI mold polish standards to categorize the surface finish quality of molds used for plastic injection molding, which directly impacts the appearance and texture of the molded parts. […]
Process of creating a plastic injection mold
Creating an injection mold is a complex process that involves multiple stages, each requiring precision and expertise. Here’s an overview of the typical procedures for making an injection mold: 1. Concept and Design Product Design: Begin with the design of the part to be molded. This includes considering the material, shape, dimensions, tolerances, and other […]
Achieving Precision with Insert Molding – Elevating Manufacturing Solutions
The Significance of Insert Molding Insert molding has emerged as a pivotal technique in modern manufacturing. This process involves embedding a pre-fabricated component, typically made of metal or plastic, into the mold before injecting the surrounding material. Engineers turn to insert molding for its ability to enhance product strength, improve assembly efficiency, and reduce manufacturing […]
Dynamic Balance Challenge – Molding a Fan for Vacuum Cleaners
The Significance of Dynamic Balance The role of dynamic balance in molding a fan for vacuum cleaners cannot be overstated. These seemingly simple components, integral to the functionality of vacuum cleaners, must maintain precise balance while spinning at high speeds. Achieving dynamic balance ensures efficient operation, reduces noise, minimizes wear and tear, and ultimately enhances […]
