Plastic Injection Molding: The Cooling Rate Process

  In plastic injection molding, the cooling rate is the last section of the molding cycle. The cooling rate is a decreasing rate from the time the plastic resin enters the mold until the last cavity of the mold is filled. The cooling process is complete when the temperature is no longer reducing, and any […]

What Are The Requirements For Injection Molding Machines For Precision Injection Molding?

  Precision injection molding machine refers to the molding machinery and equipment that is suitable for molding and producing precision plastic products. For a precision injection molding machine, how should we measure or judge it? Many precision injection molding also requires injection molding machines with ① High injection pressure and high injection speed. ②Mold clamping […]

Two-Shot Molding vs. Overmolding

Two-Shot Molding vs. Overmolding Injection molding is a popular manufacturing process, which can quickly produce complex-shaped precise parts without wasting a lot of materials. Many different processes belong to the category of injection molding, including over-molding and two-shot molding. The two processes are similar, but there are some key differences-here are what engineers and designers need […]

Common Defects Of Injection Molds And Their Solutions

  An injection mold is a tool for producing plastic products and for giving them a complete structure and precise dimensions. Read on for more information about common problems and solutions for injection molds.   A mismatch between mold and injection molding machine Causes: 1. Positioning ring position is not correct, size is too big […]

What is Unscrewing Mold?

  One of the most unique types of injection molds is unscrewing molds. Unscrewing molding is a unique injection molding process with mold technology that includes movement and rotation to produce threaded components. Some plastic parts such as caps and closures with detailed threads cannot be removed using standard knock-off methods. After they are molded, […]

Two-shot Molding Guide

  What is Two-shot Molding Two-shot injection molding is a multi-material injection molding process. The molded plastic part can be a combination of two different materials or a combination of different colors of the same material. Two-shot molding can also be called 2k injection molding, double shot molding, multiple injection molding (sequential injection molding). When […]

Just How Tolerances Influence Injection Molded Plastics?

What Is Tolerance? The tolerance stated in the plastic injection mold is an engineering requirement. In basic terms, they are allowable variants to the initial dimensions of the parts or the base dimension. As it is impossible to generate a product that purely abides by the base measurements, some leeway obtains factored into the design […]

Pros And Cons Of Thermoset Injection Molding

Weighing the pros and cons of the molding process for your composites can help you determine whether it is the right choice for your project needs. Manufacturing plastic or composite parts requires heating and pouring the raw materials into a mold that has been specially made for the part. The four most common molding processes […]

Insert Molding VS. Overmolding: What’s the Difference?

  There are various sub-processes within injection molding that add further capabilities to this already versatile technology. This article will explore insert molding vs overmolding and the advantages of each. Injection molding is a broad term used to describe one of the most important processes in the manufacturing industry. It’s a process that requires a […]

Difference between Thermoset & Thermoplastic Injection Molding

  Thermoplastics and thermosetting plastics are two separate classes of polymers that are widely used in the process of injection molding to create products of various types. Both these categories of plastics possess different properties and characteristics. Hence, choosing the right category of polymer, between the two, is of paramount importance to achieve the expected […]
