Shear rate is one of the most important concepts to understand in injection molding. As a plastic injection molding manufacturer, today we’ll cover that optimizing shear rate is crucial for producing high-quality parts while protecting your molds. What Exactly is Shear Rate in Injection Molding? In simple terms, shear rate measures the change in velocity between […]

In this complete guide, as a professional plastic injection molding manufacturer, we’ll cover what causes sink marks and how to prevent them through better part design and processing.

Injection molding is an integral part of modern manufacturing. This process creates complex plastic parts at high speed using molds. When heated plastic gets injected into the mold, it travels through a channel called a sprue. So what exactly is a sprue in injection molding? As a professional plastic injection molding manufacturer, I will help

What Is Switchover Position in Injection Molding? The switchover position, also known as the V/P switchover point, is a crucial transition point in the injection molding process. This position indicates when the injection molding machine switches from a velocity-driven filling stage to a pressure-driven packing stage. Understanding what the switchover position is and how to

Injection molding relies on having the right amount of molten plastic, or “shot size”, to completely fill the mold cavity. The cushion refers to extra shot capacity beyond what is required to fill the mold. This plastic cushion serves the vital purpose of maintaining pressure against the cooling, shrinking material in the mold during the

Injection molding and extrusion are two of the most common manufacturing processes for producing plastic parts. At a glance, they may seem similar – after all, both processes involve melting down plastic and forming it into custom shapes. However, injection molding and extrusion utilize different equipment and techniques to serve unique applications. As a professional

What exactly is a parting line? And why does its placement matter when designing parts for injection molding? As a professional plastic injection molding manufacturer, I’ll explain everything in this comprehensive guide.

Injection molding can produce high volumes of plastic parts efficiently and precisely. However, the high initial costs make small batch production expensive. Is injection molding ultimately a cost-efficient process? As with most manufacturing processes, the cost dynamics depend greatly on the production volume. As a professional plastic injection molding manufacturer, I will help you find

In injection molding, tonnage refers to the clamping force of the injection molding machine. It determines how much pressure can be applied to keep the mold closed during the injection of molten plastic. Understanding tonnage is key for producing high-quality plastic parts efficiently. In this complete guide, as a professional plastic injection molding manufacturer, I’ll

Transfer position is one of the most crucial yet often overlooked aspects of the injection molding process. As a professional plastic injection molding manufacturer, I want to lift the veil on this key technique and explain precisely what the transfer position is and why it matters so much. What is Transfer Position in Injection Molding?
