Part manufacturers should always give careful consideration to the materials used in plastic part design, as this decision will have significant consequences for sink and warp in plastic injection-molded parts. Let’s take a look at what makes a part sink or warp, and some helpful advice for avoiding these in the injection molding and design […]
Polyoxymethylene (POM), commonly known as acetal plastic or acetal resin, is an engineering thermoplastic widely recognized for its superior mechanical properties, dimensional stability, and resistance to moisture and chemicals. In this blog, we’ll explore the defining characteristics of POM, its advantages in injection molding, how it compares to acetal resin, and the diverse applications that […]
Plastic Rib Design Ribs are a great way to add strength and stiffness to a plastic part without significantly increasing material usage or overall part weight. When designed correctly, ribs help prevent flexing, warping, and deformation in large flat surfaces, allowing designers to maintain thinner nominal wall sections. This approach not only improves part performance […]
In injection molding, part ejection is one of the most important stages of the manufacturing process. Once molten plastic cools inside the mold, the finished part must separate cleanly from the tooling before the next cycle can begin. If ejection is not properly considered during product design, parts may stick, warp, crack, or suffer cosmetic […]
Lightweighting has become an increasingly important strategy in plastic part design, particularly for companies looking to improve efficiency and reduce material consumption without compromising performance. In injection molding, lightweighting involves optimizing part geometry, material selection, and structural design to reduce overall weight while maintaining the strength required for the application. While lightweighting is often associated […]
Sealing performance is often one of the most critical but overlooked aspects of plastic part design. Preventing water intrusion, blocking dust, and maintaining internal pressure are cornerstones of properly designed gaskets and sealing features. They truly determine the long-term success of a product. In injection molded assemblies, sealing is not just about adding a gasket. […]
What is fatigue strength in plastic parts? Fatigue strength refers to a plastic part’s ability to withstand repeated or cyclic loading over time without cracking or failing. Unlike single-load strength, fatigue strength focuses on how materials behave when stress is applied again and again, even if that stress is well below the part’s maximum strength […]
Understanding Injection Molding Defects Injection molding defects are flaws that compromise a part’s appearance, performance, or dimensional accuracy. While some defects are cosmetic, others can impact structural integrity, function, or downstream assembly, making early detection and prevention critical in production environments. Understanding why defects occur allows manufacturers to make informed decisions around material selection, mold […]
What is sustainable injection molding? Sustainable injection molding refers to the practice of designing, selecting materials, and executing production in a way that minimizes environmental impact while maintaining quality and performance. Rather than simply making plastic parts, it means choosing smarter resins, optimizing energy usage, reducing waste, and extending product lifecycles so the part you […]
When you need plastic parts for your product, you want a plastics manufacturer that is reliable, affordable, and produces high-quality parts. There may be a lot of options, so it is important to narrow down the field with the right criteria. What is a plastics manufacturer, and what do they do? A plastics manufacturer is […]
