Slow wire walking, also called low-speed wire walking, is a kind of CNC machining machine tool that uses continuously moving fine metal wire as an electrode to pulse spark discharge on the workpiece to generate a high temperature of over 6000 degrees, ablate metal and cut into a workpiece. The principle of wire processing is the phenomenon that there is a gap between the wire electrode and the workpiece, and the metal is removed by continuous discharge. Since the slow-moving wire cutting machine adopts the method of wire electrode continuous feeding, that is, the wire electrode is processed during the movement, so even if the wire electrode is worn out, it can be continuously supplemented, so it can improve the machining accuracy of the parts and slow the wire. The surface roughness of the workpiece processed by the cutting machine can usually reach Ra=0.8μm and above, and the roundness error, linear error and dimensional error of the slow-moving wire cutting machine are much bett...
The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th...
KOVAR parts are commonly used as metal casing materials in the electronic packaging industry. Because they have a linear expansion coefficient close to that of molybdenum group glass, and can produce less sealing stress during the sealing (melting) process with molybdenum group glass, so To obtain good air-tightness, in order to make the metal tube and shell to achieve air-tight sealing, in the entire sealing process, the annealing process undoubtedly plays an important role as a link between the previous and the next. The internal stress generated during KOVAR machining also prepares the material structure for the implementation of the subsequent process-the sealing process of the metal parts. The main purpose of annealing Kovar shell before sealing is to: (1) Eliminate machining stress. When Kovar undergoes plastic machining deformation during cold working, about 10% to 15% of the applied energy is converted into internal energy, which is commonly referred to as internal stre...
1. Titanium reactor: Due to the different production process and operating conditions of the user, the jacket heating type is divided into electric heating rod heating, steam heating, heat transfer oil circulation heating, and the shaft seal device is divided into packing seal and mechanical seal. The stirring mode is anchor type, paddle type, disc, push or frame. The number of openings, specifications or other requirements can be designed and manufactured according to user requirements.

2. Titanium capacitor Material-based tube condensers: Composite titanium tube condensing, titanium tower tube condensing, carbon steel and titanium mixed tube condensing are classified into three types according to the morphology of the fixed tube sheet. Floating heads and U-shaped tubular heat exchangers are divided into single tube, double tube and multiple tubes depending on the structure. The heat transfer area ranges from 0.5 to 500 m 2 and can be customized to meet the different needs of the user.
3. Titanium can: The fermenter designed in our factory is a standard tank type. This type of canister uses the jacket type when the nominal volume is less than 6 cubic meters. Cooling or heating of the fermentation gas is done through the jacket. When the nominal volume exceeded 6 cubic meters, the fermentation gas was cooled by vertical tubes, improving the connection of the tubes within the tubes. This is primarily to avoid puncturing the can and blocking the edges of the can. This continuous mode is practically sufficient. Fermenter tanks can be divided into two categories: One is corn that is fermented by gas (eg alcoholic fermentation). The other is a gas fermenter (for example, standard type, Wu type, self-priming type, etc.). This type of equipment is most commonly used in standard tank types. The series of fermenter series designed in our factory belongs to the standard tank type. When designing fermenters of various specifications, the design is compact, strong enough and has a good service life. The company strives to reduce internal accessories and smooth the surface. It should be noted that good gas contact and stagnation of solids and physical properties must be present for efficient material transfer and gas exchange. There is sufficient heat exchange area to ensure fermentation at optimum temperature. Pay attention to the sealing performance of the device to ensure sterilization.

4. Titanium cooler: Main application: Mainly used for concentrating liquid materials in industrial fields such as pharmaceuticals, foods and chemistry, and also capable of alcohol and simple backflow extraction. Structure: The device mainly consists of a concentration tank, a first condenser, a gas-liquid separator, a second condenser, a cooler, and a six-part liquid receiving tank, all made of titanium. The concentration tank has a jacket structure, the condenser is a column tube type, and the cooler is a coil type. [Requirements can be designed and created according to user requirements]
