Multiple cavity tooling is an excellent solution for the right project. Here are some of the advantages. Positives of Using Multi Cavity Tooling More parts per cycle, so suitable for larger ordersLower cost per piece that a single cavity toolBetter color consistency between partsThere are, as always, some compromises that product developers should be aware …

Although every product is unique, the following design tips represent the ‘best practices’ that have been derived from decades of practical experience within the plastic injection molding industry. Product developers are well-advised to consider these guidelines for the following common design features. A boss is a relatively large mass of plastic resin. Whenever there is …
Design for manufacturing guidelines for plastic injection molding Read More »
Surface textures and patterns applied to plastic injection molded parts are becoming more sophisticated and complex. These advancements are exciting because they offer so many new design options for product developers and engineers. But before a finished part can be made, the injection molding tool must first be carefully manufactured. So how do manufacturers apply …
Common Methods for Applying Textures to Injection Molding Tools Read More »
The higher you go in the classification system of surface finishes for mold tools, the more time and effort it takes to produce the finish. In fact, each step of refinement requires first completing the step preceding it. There are no shortcuts here so the costs are additive. Let’s see how each finish is done. …
Color consistency is a critical factor in the injection molding industry, directly impacting product aesthetics, brand perception, and customer satisfaction. However, achieving uniform color across batches and production runs remains a challenge due to variables like material selection, process parameters, and environmental conditions. Here’s how manufacturers can address these issues effectively. By prioritizing material quality, …
Achieving Consistent Color Quality in Injection-Molded Parts Read More »
There are three ways to make custom colors for plastic injection molded parts. For low volumes, only the first option makes economic sense, but in that case, achieving color consistency will be very difficult. Alternately, using compound custom material, or using a masterbatch colorant, allows color consistency within batches. But these methods are only suited …
In the competitive world of injection molding, reducing cycle time without compromising quality is a top priority for manufacturers. Shorter cycle times directly translate to higher output, lower costs, and improved profitability. However, achieving this requires a holistic approach that considers material selection, mold design, process parameters, and machine efficiency. Here are some proven strategies …
Optimizing Injection Molding Cycle Time: Key Strategies for Enhanced Productivity Read More »
The terminology “core” and “cavity” designate two different parts of an injection mold that you can distinguish by their more or less obvious characteristics. For example their appearance, structure, shape, position, or markings. Here is how they are identifiable; The general look: The core of a mold is the portion of the part tool that …
How to Distinguish Core and Cavity in Injection Molding Read More »
You can easily distinguish the core and cavity sections of an injection mold; they form the two halves that create a complete mold, where molten plastic is injected during the process. The core portion is responsible for providing the internal surface, whereas the cavity forms the exterior surface. The core is the part that, is …
What Are the Core and Cavity in Injection Molding Read More »
Injection molding is a common manufacturing process, and its principle is not complicated: the heated and melted material is injected into a mold like “injection”, and after it cools and solidifies, it becomes the product or part we need. The shape inside the mold determines the appearance of the final product. In order to ensure …
