About different Casting method


  • Moulding - the process of making moulding by using the prepared moulding sand and shape.

  • Manual molding - the molding process completed entirely by hand or hand tools.

Manual modeling operation is flexible, adaptable, simple process and equipment, low cost, but its casting quality is unstable, low productivity, high labor intensity, high requirements on operation skills.

Machine moulding cannot be used in dry sand mold casting, it is difficult to produce huge castings, and it cannot be used in three-box moulding. At the same time, it is necessary to avoid live block moulding.

There are many types of molding machine, its compact sand and different mode of mold. Machine modeling according to the different compaction mode, the four basic ways of compaction modeling, shock pressure modeling, sand throwing and sand shooting modeling.

Additional Product Information


  • Valve function and use

(1) Cut-off categories: gate valves, globe valves, plug valves, ball valves, butterfly valves, needle valves, diaphragm valves, etc. Truncated valves, also known as closed-circuit valves and globe valves, act to switch on or cut off the medium in the pipeline.
Check valve, check valve, also known as check valve or check valve, check valve is an automatic valve, its role is to prevent the back flow of the medium in the pipeline, to prevent the reverse rotation of the pump and the drive motor, and the leakage of the container medium . The bottom valve of the pump is also a check valve.
Explosion-proof valve, accident valve, etc. The role of the safety valve is to prevent the medium pressure in the pipeline or device from exceeding the specified value, so as to achieve the purpose of safety protection.
Regulating valve, throttle valve and pressure reducing valve, its role is to adjust the pressure, flow and other parameters of the medium.
(2) Vacuum: vacuum ball valve, vacuum flapper valve, vacuum inflation valve, pneumatic vacuum valve, etc. Its role is in the vacuum system, used to change the direction of the air flow, adjust the size of the air flow, cut off or connect the vacuum system components called the vacuum valve.
