In this blog, you can learn shrinkage in polymers and PVT diagram for amorphous and crystalline material.
New Calculators
Recently we have added new shot size, plasticizing calculators and updated residence time calculators for accuracy. Please check it out!
New Polymer Abbreviation
Recently we have added polymer and filler abbreviation page. Please check out “Poly Abb+” page and take a test drive. Hope you will like it!
Injection rate
In this blog we discuss injection rate setup in an injection molding machine. Velocity profile and packaging machines are shown as an example.
# of cavities?
This is the questions asked by molder, OEM or mold designer when starting a project. The answer depends on multiple situations and this blog takes you different scenarios to consider.
Advanced Valve Gate- HRSFLOW’s FLEXflow EVO
This blog introduces FLEXflow EVO family of hot runners from HRSflow hot runner company. We are discussing two products within the FLEXflow family of servo controlled valves and their advantages.
Barrel Heats
Here in this blog, we discuss barrel heats and how to set for correct temperatures. Different heat profiles are discussed.
Screw Positions
This blog discusses the screw position in an injection molding process. During the entire injection molding cycle, the screw position varies and this blog takes you step by step.
Intensification Ratio
Here is the blog on Intensification ratio calculation. This is only used for injection molding hydraulic machines and blog takes you step by step approach. Don’t be puzzled anymore!
Screw Design – Parameters
This blog discusses the four important parameters for screw design. This is a continuation of screw terminology blog.
Injection Screw Terminology
This blog introduces screw terminology which is a precursor for more blog coming in the pipeline. The basics of screw are covered in a short video.
Shot Size Calculation – Metric Units (Outside USA)
In this blog, we are using step by step approach to shot size calculation using metric units. This is the most sort out calculation in the molding industry.
Shot Size Calculation – Imperial Units (USA)
In this blog, we are using step by step approach to shot size calculation using imperial units. This is the most sort out calculation in the molding industry.
Plasticizing Calculation
In this blog we discuss the plasticizing calculation and explanation of the molding cycle. Discussion includes both Imperial and metric calculation.
Still MFI?
This blog discusses the drawbacks of picking a material purely on MFI. Shows the real world data with Therma-flo results which will be a better way to pick a material on flow properties.
