VMT 2025 11 25 Perhaps you're preparing to design a lampshade for the outdoor use, an observation window for a biosafety cabinet in the medical, or maybe your next project will design kind of security equipment such as the police face shields. Or you're an automative factory designing headlight lenses and dashboard covers. All of these require a transparent and lightweight material, and depending on your specific application, you'll need this material to possess certain properties such as good optical properties, UV resistance, explosion and impact resistance, chemical corrosion resistance, or scratch resistance, as well as considering factors like cost and processing. For engineering requirements, acrylic (PMMA) and polycarbonate (PC)—two of the most commonly used and high-performance transparent plastics—may meet your needs. This article will guide you through understanding the core properties and comparisons of acrylic (acrylic) and polycarbonate (PC), helping you understand whether they are suitable for your project.

VMT 2025 11 20 Forging shapes metal through pressure and heat, while fabrication combines cutting, welding, and assembling different metal pieces. Forging is best for high-strength parts, and fabrication is ideal for custom fabrication and complex structures. Choosing between them depends on strength requirements, shape complexity, budget, and production volume.

VMT 2025 11 19 If a common alloy material, aluminum alloy with silicon（Si）addition, happens to be used in your engineering project, you surely understand that the additon of silicon（Si） must be enhancing certain properties of the aluminum alloy. But maybe you will be wondering—what does the silicon（Si）belongs to ? Metal or nonmetal? This article will illustrate elements like silicon（Si）—the metalloids, and their properties and applications. After learning about how metalloids play an important role in industries, there might be some useful references provided for your material selection and application design.

VMT 2025 11 18 Plastic materials are widely used in manufacturing plastic parts in engineering. The selection of plastic materials depends on the required material properties , that is, the properties of the plastic itself. So, when you select the plastic materials for your projects , have you ever wondered the causes of the plastic’s properties in chemistry? This article will share you knowledge of copolymers and homopolymers. With examples of four common plastic materials, you will understand what properties plastics have when they are copolymers or homopolymers.

VMT 2025 11 18 CNC machining removes material to create strong, precise parts, while additive manufacturing (AM) builds parts layer by layer for complex shapes and rapid prototyping. You should choose CNC for tight tolerances, durability, and production volumes, and use AM for fast prototypes, lightweight structures, and designs that traditional subtractive machining cannot achieve.

VMT 2025 11 15 To choose between CNC milling and laser cutting, compare your material type, required precision, part geometry, and production speed. CNC milling is best for thick materials and complex 3D shapes, while laser cutting is ideal for fast, clean 2D cutting. Choose the process that aligns with your tolerance needs, budget, and design requirements.
