Sibai doesn’t focusing on production bolt and pins. But if customer requires, we can help purchase from Chinese supplier. Besides this, Sibai can produce the custom stainless steel bolts or pins according to customers specific designed drawings. Sibai custom bolts and fasteners Features Bolt is a cylindrical threaded fastener with a nut. A type of fastener consists of a head and a screw (a cylinder with an external thread), which needs to be matched with a nut to fasten. Pin is used to position and fasten components. There are two types, cylindrical and conical. The installation of pins generally adopts two methods, press-in method or knock-in with soft metal. Pins are usually conical, pointed or pointed wood or metal pegs, to nail or fasten or to fill holes. Sibai doesn't focus on production custom carriage bolts and pins. But if customer requires, we can help purchase from Chinese supplier. Besides this, Sibai can produce the custom eye bolts or pins according to customers specific designed drawings. There are several processings: Head forming processing: The inner end side of the high-strength bolt and the center line of the rod have verticality requirements, generally between 0.04- 0.10mm. In order to ensure the tensile strength of the high-strength bolt, the inner end face is required to be chamfered R, value generally R1 ± 0.5. Rod processing: external surface processing by turning and grinding, the semi- finishing accuracy can reach IT10-IT9, and the surface roughness value can be Ra 6.3 - 3.2um. Cylindrical grinding is the main method of cylindrical finishing, generally after heat treatment. Thread processing: There are several ways to produce thread, turning, milling, grinding, rolling, etc. For high-strength bolts, we choose rolling threads. Rolling is a chip-free machining process. The thread is formed by cold forming. Rolling has high capacity. Heat treatment: treatment of high-strength bolts (quenching and high temperature tempering). Surface treatment: according to customers requirements, there are several common surface treatment for bolts and pins, dacromet, zinc plating, surface phosphating. Galvanization and phosphating are mostly used in our past production experience. Sibai also exports a large number of fasteners, especially high-strength custom bolts. If you have production needs for custom bolts and pins, please contact me for a quote. thanks. Sibaicnc, as an excellent cnc machining manufacturer, offers a wide range of precision machining for you to choose from.

What is LED? LED is sanded for Light Emitting Diode, a kind of semiconductor which is used to give and receive the electronic signal into infrared rays or light, using the characteristics of compound semiconductor. This is used for household appliances, remote controller, electric bulletin board, various kinds of automation appliances. 2. What are Pixel Pitch, Pixel Density, LED QTY, and Pixel Configuration? Pixel Pitch is the distance between neighboring pixels. Pixel Density is the quantity of pixels per square meter. LED QTY is the quantity of LED lamps per square. Pixel Configuration is the description of the consistence of a pixel, for instance, we use 1 red lamp, 1 green lamp, and 1 blue lamp to compose a pixel, the pixel configuration is 1R1G1B. 3. What are LED Type, Module size and Module resolution? LED Type is the description of LED lamp, for instance, the brand, the shape in physical, the size of the lamp, etc. Module size is the measurement of a module. Module resolution is the number of pixels per module. 4. What is Drive Method, driving IC and Power supply Drive Method: always we use static, 1/4 scan, 1/8 scan, 1/16 scan, the latter one contributes to less brightness than the former. We always use the static outdoor, and use the different kinds of scan indoor. Driving IC is the generic term for several kinds of IC, that are used to control the LED lamps, and as a bridge between the control system and lamps. Power supply: a kind of device that used as a transfer from 220V AC into 5V DC. It always seems like a box in the cabinet. 5. What is viewing angle? Viewing angle is the maximum angle at which a display can be viewed with acceptable visual performance. It includes horizontal viewing angle and vertical viewing angle.
