Polishing and texturing are the last steps of tooling. Polishing, also known as buffing, is a finishing process that uses abrasives and work wheels or leather slides to smooth the surface of the workpiece. Technically speaking, polishing refers to the process of polishing with abrasives attached to the working wheel. Polishing is usually used to enhance the appearance of objects, prevent contamination of instruments, eliminate oxidation, form reflective surfaces, or prevent corrosion of [...]

Mold fitting is one of the most critical steps in the die manufacturing process. All the parts that are processed or purchased must be assembled and functional. Mold fitting requires a comprehensive understanding of mold structure and injection molding. The quality of mold fitting determines the precision of the mold and injection productivity. Several parts that need to be paid attention to in the assembly mainly affect the quality of the product include: [...]

Overview of EDM Electrical discharge machining, or EDM, is an unconventional method in which heat energy is used to remove material from the workpiece. Very similar to processes such as laser cutting, EDM does not require mechanical force in the removal process. EDM is very popular in tool and die manufacturing for its applicability, especially to hard materials such as titanium or particularly complex shapes that are difficult to obtain through milling. To [...]

Heat treatment is a group of industrial, thermal, and metalworking processes used to alter the physical and sometimes chemical properties of a material. Heat treatment involves the use of heating or cooling (usually to an extreme temperature) to achieve desired results, such as hardening or softening of the material. The heat treatment process allows the material to be machined, and once the metal has formed the desired shape, the heated metal is quickly cooled. [...]

The characteristics of rough machining Roughing is intended to remove a large amount of material. For example, in the first roughing process, a material removal process is performed until the most likely surface is reached or the workpiece is completely cut. Therefore, the selected roughing tool must be of sufficient length to cut through the workpiece. The main reason for machining to maximum cutting levels is to avoid the formation of thin layers [...]

An ejection system in injection molding is used to push the final sample out of the mold. They are used powerfully to push solid parts out of molds, usually made of high-quality steel. There are various types of injector systems. It relates to the shape, structure, and plastic properties of the product. Generally have ejector pin, jacking tube, stripper plate, ejector block, square ejector, and so on. How does the ejection system work? [...]

The choice of die steel is important if the die is to operate efficiently. To avoid costly long-term mistakes, the use of plastic molds must be thoroughly investigated and fully understood before making a selection decision. The mold has a high demand for steel. The correct choice of steel has a great influence on the service life, machinability, and precision of the die. The requirements vary according to the structure of the mold, [...]
