Barrel Electroplating: An Overview Barrel electroplating is a method designed for the efficient electroplating of numerous small parts within a rotating container. This technique is widely utilized for various metal coatings, including galvanizing steel components, copper plating, nickel plating for copper and its alloys, and tin or chromium coatings. 1. Introduction to Barrel Plating Barrel plating is particularly suitable for small parts that are difficult to plate due to their size or shape....
The Impact of Screw and Barrel Quality on Extruder Performance The performance of an extruder is significantly influenced by the interplay between its two key components: the screw and the barrel. The quality of their operation directly affects material plasticization, product quality, and overall production efficiency. The effectiveness of these components is closely tied to their manufacturing precision and the assembly tolerances maintained during installation. When wear occurs in either...
In recent years, as people's living standards have increased, cars have entered homes, the demand for plastics has increased, the popularity of VCDs, the advent of DVDs, and the demand for transparent plastics have become greater. As a transparent plastic, PMMA has a high light transmittance. Widely used in high-precision telescope lenses, eyepieces, objectives, but the injection molding process has been difficult to break through, and the technology has been monopolized by Japan, although...
PC plastic is known as polycarbonate, because of its excellent mechanical properties, commonly known as bulletproof plastic. PC plastics have high mechanical strength, wide temperature range, good electrical insulation performance (but no anti-arcing performance), good dimensional stability, and transparency. It is widely used in electrical products, electrical instrument casings, electronic product structural parts. There are many modified PC products, usually adding glass fiber, mineral...
