Key points of PEEK material injection molding process

Polyetheretherketone, PEEK resin (PEEK for short) is a new type of semi-crystalline aromatic thermoplastic engineering plastic made by condensing "difluorobenzophenone" and "hydroquinone" in the presence of alkaline metal carbonate and using diphenylsulfone as solvent. Compared with other special engineering plastics, PEEK has more significant advantages, such as high temperature resistance of 260 degrees, excellent mechanical properties, good self-lubricating properties, chemical corrosion resistance, flame retardant, peeling resistance, wear resistance, but not strong nitric acid resistance, radiation resistance, and super mechanical properties. It can be used in high-end machinery and aviation technology.

How are the teeth processed?

How are the teeth processed?

Transparent plastics must have high transparency, certain strength and wear resistance, impact resistance, good heat resistance, excellent chemical resistance, and low water absorption. Only in this way can they meet the transparency requirements and remain unchanged for a long time during use. Commonly used transparent plastics are: 1. Polymethyl methacrylate (commonly known as acrylic or plexiglass, codename PMMA),

Outlook and prospects of China's cutting tool manufacturing industry from 2022 to 2028

Outlook and prospects of China's cutting tool manufacturing industry from 2022 to 2028

At present, my country's metal cutting tools have begun to shift from high-speed steel tools to the development and production of carbide tools, but the momentum is still not enough, and low-end products are still the majority. In recent years, my country's tool industry has developed very rapidly, and it is still maintaining a high-speed growth momentum and is expected to create a new historical high.

Which cutting fluid is better for precision gear processing - iHF Synthetic Gear

Which cutting fluid is better for precision gear processing - iHF Synthetic Gear

Cutting fluid is needed in the process of close gear processing, so which cutting fluid is better for gear processing? For high-speed gear cutting, you can choose a water-based cutting fluid with strong extreme pressure, such as a water-based synthetic cutting fluid containing sulfur and phosphorus extreme pressure additives, which can handle oil pollution during high-speed cutting, and the processing quality and tool wear are better than oil-based cutting fluid. However, for the original rolling and inserting machines, measures must be taken to prevent water from entering the rotating parts to avoid machine failure. When using carbide tools for gear processing, EC rolling hard gear cutting oil can be used to gradually reduce the temperature of the workpiece, improve the processing technology accuracy of the gear, and extend the life of the tool.

Current situation, pattern and future of cutting tools in China

Current situation, pattern and future of cutting tools in China

Anyone who has worked in a factory knows that among the key technologies in the metal processing and manufacturing industry, heat treatment relies on a good fire, and machining relies on a good knife. Zigong asked about benevolence. Confucius said: "If a worker wants to do his work well, he must first sharpen his tools." Although cutting tools seem to be insignificant in the manufacturing industry, new materials and new technologies for cutting tools emerge in an endless stream, and the methods of production, sales, and service are rich and colorful. With the rapid development of China's manufacturing industry, the share of cutting tools in the manufacturing industry has become increasingly indispensable, and must catch up.
