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.
