In plastic blow molding, the screw is often called the “heart” of the machinery. Its design directly affects production efficiency and product quality. Many people mistakenly believe that “a longer screw is always better” for plastic water tank blow molding machines. Let’s break down this myth by examining three key factors: material processing, energy efficiency, and product quality. 1. How Screw Length Affects Plastic Melting The length-to-diameter ratio (L/D) of a screw determines how well it melts plastic. While a longer screw can improve…
