Parher jic female swivel fitting standards

Common thread for connection between mechanical parts and fastening, multi-threaded connections generally coarse thread, fine thread than the same nominal diameter slightly coarse thread strength, better self-locking performance. Mark metric common thread: M20-6H, M20 × 1.5LH-6g -40, where M denotes metric common thread, 20, said thread nominal diameter of 20mm, 1.5 represents pitch, LH said L, 6H, 6g said threaded accuracy class uppercase letter said internal thread accuracy class, lower accuracy level code, said external thread, 40, said the design of injection mold screwing hydraulik monoblock length is the main direction of the profession, is a set of engineering drawings, mechanical engineering materials, with limits and tolerances, mechanical part design , mold design basis and other integrated applications related professional courses, with the presence of professional research closely. With the rise of Chinese industry, plastic, with its low cost, good technology, developed rapidly in various fields. The growing popularity of the use of plastics. To demand more and more plastic parts, plastic parts production technology monoblock hydraulic valves, has become a common issue for each industry. In the same time, the rapid development of today's economy, consumers on the quality of the plastic parts have become increasingly demanding. To meet customer needs, mold production and design should also be on a new level. The design of the threaded pipe joints, using UG rational use of three-dimensional modeling software to avoid the previous modeling a variety of other inadequacies. Ensure the accuracy of the appearance and size of plastic parts. From the current point of view, both in the development of their own, have a competitive edge in the market. But regardless of the injection molding machine, the direction of which will be to all types of low-power, low noise, easy to control the clamping force, stable, safe, reliable and easy to maintain direction. Despite the large injection molding machine has picked up the trend of the development of large injection molding machine technology can not be ignored, but it yields the current view of the injection molding machine, still mostly SMEs. Now the injection molding machine with automatic transmission, fast transfer machines, monitoring work and "Diagnostic" and other programs, which the mechanical, electrical, hydraulic, automation and computer application of injection molding machines and higher requirements; realize the system pressure, multi-level or no level flow control and measurement.
