Polishing refers to the use of mechanical, chemical, or electrochemical action to reduce the surface roughness of the workpiece to obtain a bright and smooth surface. It includes the modification of the surface of a workpiece using polishing tools and abrasive particles or other polishing media.
Casting is most commonly used to create complex shapes that would otherwise be difficult or uneconomical to make using other methods. Metal casting processes have been known for thousands of years, and have been widely used for creating sculptures, jewelry, transportation, weapons, and tools.
In the machining process, as the tool cuts off the unnecessary material from the workpiece, a cutting force will be generated on the workpiece. To resist the cutting force and allow the cutting process to be completed, the workpiece must be firmly clamped on the machine tool. The device that positions and clamps the workpiece is called a fixture. The device that holds and guides the cutting tool is called a jig.

Through the strong cooperation between...
Titanium alloys are widely used in aerospace, chemical, marine, and automotive industries due to their excellent strength-to-weight ratio, corrosion resistance, and ability to maintain strength at high temperatures. However, the disadvantages of titanium alloys are poor thermal conductivity and strong reactivity with tool materials. Their high strength, and low elastic modulus make them difficult to cut materials.
Etching is a technique to process the surface of the object by using chemical strong acid corrosion, mechanical polishing, or electrochemical electrolysis. In addition to enhancing aesthetics, it furthermore increases the added value of the object. Procedures from traditional metal processing to high-tech semiconductor manufacturing are all within the scope of applications of etching technique.
Welding is a technique and process for joining metals or other thermoplastics by heating or pressing.
Low-temperature treatment is a sub-zero process, which is carried out immediately after quenching and is carried out by continuous tempering. The ultra-cold treatment has a significant improvement in the wear strength of the workpiece and has a breakthrough benefit for the stability of the mold size.
Metal fabricators looking to take on finishing should know about two of the most common finishing alternatives—liquid and powder coating—and the requirements involved for a company hoping to apply one or both.
Metal stamping refers to the use of the power of punching machinery and the use of molds as metal plate forming tools to produce punching separation or plastic deformation effects to achieve the production technology of parts in terms of size, shape, and performance requirements.
In response to the development of international industry demand, the laser industry and technology have begun to develop towards 5G semiconductors and smart vehicle process requirements. Taiwan’s laser industry has developed for many years and has a solid foundation, but to continue to keep up with the international pace, the need for independent laser technology step up.
In the cutting of hardware components, a comprehensive analysis of factors is required, and through strict process flow, a suitable cutting process can be planned to manufacture hardware components of stable quality.
Machine tools refer to power devices used to process work pieces and are important equipment in the manufacturing process of mechanical parts. Machine tools are generally used for forming, cutting, and joining other tools.
The thread is usually the last feature added to the part. There are other challenges besides the exact parameters required and standard threading issues.
Welding is a process that uses "heat" and "electricity" to connect two pieces of metal, and the type of welding metal will also affect the welding results and technical requirements; like many professional skills, welding technology also has different levels of difficulty. First understand the most common types of welding introduction, principle teaching, and skill analysis.
Welding is a method to make two metal blocks belong together. Metal weldability is the ability of metal materials to adapt to the welding process. Under certain welding process conditions, whether it can obtain high-quality welded joints and whether the welded joints can operate safely under use conditions is an evaluation standard.
Quenching is a heat treatment process for metals and glass. Heating alloy products or glass to a certain temperature, then rapidly cooling in water, oil, or air containing minerals, generally used to increase the hardness and strength of the alloy.
The word comes from the English called plate metal. Generally, some metal sheets are plastically deformed by hand or die-stamping to form the desired shape and size and can be further formed by welding or a small amount of mechanical processing to form more complex parts.
In the field of manufacturing processing, common processing methods include broaching, boring, grinding, milling, etc.
