Thanks for visiting Polymer School. This portal is a new concept in the field of technical education by providing short videos on topics which new students in technical schools or new employee in plastics industry […]
This blog is a continuation of the IV Explained – Part 1 blog which I recently did. This blog explains the properties and practical use of IV and measurements during processing.
In this video blog, you will learn the theory of IV (Intrinsic Viscosity). We take you through why IV is used, and how it is calculated and basics of measurements.
This blog is a continuation of the drill jig video blog I recently did. Here we take you through concepting a milling slot on the same workpiece/part and explaining step by step.
We take you through an example of concepting a drill jig. How to locate, orient and clamp the workpiece, and finer details of design. This blog is useful for any designer who wants to design […]
This blog introduces you to servo control for the mold actions. We cover why servo control is better than Pneumatic or Hydraulic systems, and advantages. Second part of this blog will cover the selection and […]
Manufacturing a sub gate or a tunnel gate or a cashew gate inserts are very complicated and it takes lot of time and effort in manufacturing. Exaflow gate inserts are a simple solution to this […]
Core and cavity are the important elements of a mold. In this blog, we take you over the basics of core and cavity design and factors to consider during design.
In this blog, we explain RJG’s Decoupled molding principles, and advantages on the process consistency. We take you from basics of decoupled molding for new process engineers.
Crystallinity in a semi-crystalline polymers is important for achieving material properties. This blog takes you through the basics and factors affecting the crystallinity in polymers.
Viscosity models are used in day to day calculation in polymer industry. This blog explains viscosity basics, different models and models used in Moldflow and Moldex3D simulation software.
This blog is continuation of the earlier blog on “Hotrunner Balance Study – Test Methods”. Here we explain all the factors that affect the balance with some examples which will helpful for troubleshooting the issues […]
In this blog, we walk you through the steps of doing a balance test on a hotrunner mold. This blog covers the basic methods, steps for conducting the balance test.
This blog is a continuation of the earlier blog on Gate-Basic. Here we explore all the gate types individually and where to use them & why.
This blog takes you through the basics of gate design, gate placement and function of a gate. There is a second blog which will follow on gate types to this intro.
