Mold Structure System When designing a mold, there are four key objective factors to consider: 1. Structural Rigidity: The hardness, tensile and compressive strength, toughness, and stress distribution of the mold core, mold frame, sliders, repeat-positioning pins, and mold base must be analyzed. 2. Physical and Chemical Properties of the End Product’s Material: Select appropriate …
Processing can generally be divided into two major categories: one involves mass replication after mold creation, and the other uses various tools and specific materials to craft the required shape. Individual processing is further divided into the following three main categories: 1. Cutting: Includes drilling, milling, and turning. 2. Grinding: Includes surface grinding and cylindrical …
Alloying Elements in Tool Steels for Molds Mold steel is a type of tool steel used to manufacture various forming tools, including cold work, hot work, and plastic mold steels. What elements are used to manufacture mold steel? Major Alloying Elements: Carbon (C), Silicon (Si), Manganese (Mn), Phosphorus (P), Sulfur (S), Nickel (Ni), Chromium (Cr), …
The phrase “Diamonds are merely unremarkable carbon” highlights the essential truth that both diamonds and graphite are made of pure carbon, but in different forms, or allotropes. This discovery led to the continued pursuit of methods to artificially create diamonds. After 157 years of research, scientists found that a key factor in transforming carbon into diamonds is the use of catalysts, also known as chemical agents, to accelerate the process.
Types of ultra-precision machining Lapping This is a form of optical sanding, where the surface roughness of the workpiece is ground to a level that allows for polishing. Materials such as alumina and SiC abrasives are used along with cast iron or aluminum lapping plates for processing glass lenses. Lapping typically uses cast iron plates …
Definition of Grinding What is grinding? Grinding can be described as “an operation that reduces the surface roughness of a workpiece as much as possible without damaging its shape.” Grinding is a machining action carried out using a grinding machine. In Chinese, grinding machines are referred to as “grinders,” known as “ken sakuban” in Japan. …

Rare Earth Co-catalyst Materials Rare Earth Elements Rare earth elements possess a unique outer electron structure (4f), which allows them to serve as central atoms for coordination complexes, with coordination numbers ranging from 6 to 12. This variability in coordination numbers gives them “residual valency.” The 4f orbitals, with their seven available bonding sites, provide …
Why are raw materials so important? The selection shapes the outcome. The quality of the raw materials you use directly affects the quality of the resulting products! Rare earth materials are not only known as the “vitamins of the semiconductor industry,” but with just a small amount added, they achieve the effect of “industrial vitamins” …
Why are raw materials so important? The quality of the raw materials you use is directly related to the quality of the products you produce! Rare earth materials are not only known as “vitamins for the semiconductor industry”, but they are also used in the production of semiconductors.In different industries, the addition of just a …
