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 […]

What Is Thermoset Molding?

Many people are not aware of the advantages of thermoset materials. This guide describes the thermoset molding process and how it can benefit you. *Thermoset Molding Thermoset molding is an irreversible molding process by which malleable forms of plastic are forced into a heated mold and formed into their final shape. Thermoplastic molding is the […]

Three Questions You Need to Consider before Choosing Precision Molding

  If you need a plastic part molded with extreme precision—for example, to ensure there’s no air leak between two molded sections or to be certain there’s no visible seal gap line—you likely require precision molding. The difference between a typical injection molded part and a precision molded part is the tolerance, or acceptable range […]

The Ultimate Guide to Gas Assist Injection Molding

  What is Gas Assist Injection Molding? Gas assist injection molding (GAIM) is an enhanced injection molding process often applied for complex parts, large parts and parts requiring an attractive, cosmetic finish. The types of parts benefiting most from this process include: large panels enclosures handles doors and bezels tube or rod-shaped parts How Does […]

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 […]
