The rare-earth metal thick film heating technology is one of today's most innovation and forward-looking solution for electric heating field.The thick film heating tubes/elements are produced by screen-printing dielectrics (5 layers), resistance (palladium-silver), conductor (silver) and isolation glazes on the substrate and sintered 7-9 times at temperature over 900℃.
With 2200W Thick Film Heating Tube simple tubular structure, it can heat water flow inside the tube. Electric Circuit printed on tube surface, to heat the water flow inside. For applications where space is limited, this simple profile heater offers high thermal power density and fast response times to heat up or cool down (due to low thermal mass)
JIEDA company can supply
products according to customers' drawings and offer our clients reasonable
prices. Our company also can develop heating solutions
and products together with customers.

Filled dry sand(without adhesive,no mixing)in the flask,both sides of flask are covered with plastic film,and evacuated air inside,under a certain vacuum condition sand will lose relative motion,and then forming a mold.
The principle of V-process:
1.Pattern and film heating
1)Fix pattern on the pattern carrier,and drilling holes on the pattern.
2)Heating the film.
3)Cover the heated film on the pattern.
2.Film forming and spraying coating.
Sparying coating on the formed film.
3.Place the flask
1)Keep the pattern carrier under negative pressure.
2)Putting the flask on the pattern which had covered by film and coating.
4.Vibrating and sand filling
1)Keep the pattern carrier under the negative pressure.
2)Filling the dry sand of appropriate mesh into the flask.
3)Vibrating to improve sand density.
5.Covering back  film
1)Buldozing the surface of mold.
2)Covering the plastic film on the back of flask.
3)Connected the flask with the vacuum system.
6.Stripping
1)Relieving negative pressure of pattern carrier,pattern lose the attraction of EVA film
2)Stripping,and then molding completed.
7.Assembling flask and pouring
1)Molding the upper part and low part mold inthe same way.
2)Assembling flask with dowel pins,fastening the upper and lower parts.
3)Pouring under negative pressure.
8.Shakingout
1)After cooling for a specific time,relieved negative pressure of flask,sand wikll fall down with cast under normal pressure.
2)Sundries(like waste plastics,iron slag)are sieved from sand,sand will be reused after cooling.
