INTRODUCTION In discussing the construction of plastic injection molds, it is common to hear people refer to “reverse molds.” What does this mean and how are they different from standard injection molds? Why would someone make a reverse mold? What are their advantages and disadvantages? Here is a brief summary of our analysis. STANDARD TOOLING In the majority of plastic injection molds the core side is clamped onto the movable platen and the cavity side is clamped on the fixed platen. A platen is simply a heavy plate made of steel. In an electrical analogy the mold’s cavity would be the socket ..read more

Over-Molding Plastic Over-molding refers to the injection molding technique where a material (usually TPE) is molded on a second (usually rigid plastic) using heat, pressure and liquid silicone. TPE over-molding designs that are properly chosen will create a strong bond between the plastic and TPE. This bond is then maintained even in the environment of end-use. No primers or glues are required to create a strong bond between the materials. Why use plastic substrate molding? Over-molding is used to improve the aesthetics and functionality of products Plastic over-molding can create a variety o ..read more

As a custom plastic part evolves from a concept to reality, it may pass through multiple design stages. A 2D drawing provides the basis for creating a 3D CAD rendering of the manufactured part. There may be very good reasons for considering prototype injection molding before mass production. Considerations will help you determine your prototyping requirements. Real injection-molded prototypes can be a good option if you have parts with functional features that need very tight manufacturing tolerances, or if the appearance of your product is important. Injection-molded prototypes vs. 3D-printed ..read more

What are the main benefits of plastic injection molding? The most cost-effective way to manufacture is by using injection molding. Other factors include the durability of plastic parts, client and customer satisfaction, part tolerances, and overall labor cost. Plastic injection molding has become one of the most common forms of manufacturing. Injection molding is a cost-effective way to produce products for engineers and manufacturers from all industries. The cost effectiveness of a product is not limited to initial material and machining costs. This claim is influenced by many factors, includ ..read more

Attention to detail is key in all manufacturing. One of the most important details in injection molding is well-designed, precise and high-quality tooling. Injection mold tool is a mold or die that is used to inject material into during the molding process. It is impossible to underestimate the impact that tools have on injection molding. The cost of tooling can be a significant part of the budget for any project. It is important to ensure high quality output. This post will discuss the design of injection molding tools, how to manufacture them correctly, and why they’re so important. Injectio ..read more

This process is very versatile, and it can be used to produce many different parts for various applications. You have a variety of options when creating a product requiring molded plastic components. These processes vary depending on what type of product you are making and the type of part that you need. Injection molding is one of the most popular methods for producing high-quality and cost-effective plastic parts. Injection molding allows for the production of large quantities of parts – thousands or millions. Melted resin is injected until the mold is filled to capacity. Injection molding u ..read more

Overmolding involves an injection molding technique that is used to mold a plastic component (commonly, a rubbery plastic called TPE), over another component (substrate). The substrate can be an injection-molded part or other material. Overmolding has many applications in a variety of industries. Here are some examples of overmolding: Grips– In general, components with handles need something that helps the operator to maintain grip. Overmolded grips provide a safer grip for operators, especially when wet. Vibration dampening– Rubber bumpers and mounts protect electronic components from vibrat ..read more
