1.It is specially made of high carbon steel raw material by means of CNC processing, with good quality and high tension stress. Compression ratio of mould can be calculated according to the pressed objects; Single circuit can be furnished with single circuit pump and double circuit can be furnished with double circuits pump; In time of outdoor construction, engine electric generator or engine pump can be finished to make construction conducted in a quickest and safe way for only 8-12 seconds each time. Hardware fittings are manufactured in accordance with state standard and CNC linear dimension standard with precise accuracy degree.

Selection and use methods:
Firstly measure the external diameter of hard fittings,which is equal to press mould"A"dimension in principle,please choose applicable press mould from serial number table of common press mould according to external diamerer of hardware fittings and tool model.For example,YD-240/30 connection pipes,when steel bushing external diameter is 20mm,external diameter of aluminum bushing pipe is 36mm and hydrostatic machine with 100tons of discharging force is considered as a tool,it is advisable to selection and us 100-G20 steel mould and 100-L36 for pressing purpose.
