Vacuum seal molding called V method molding, the process is a physical mehtod by using of single dry sand(no water binder and appendages), molding by plastic film with vent and suction devices,after heating and then sealed the sand box, pumping out air by vacuum pump, the pressure compact the dry sand to the needed shape.
Usually the V method casting line includes molding units and sand processing units.The main equipments are as followed:
Molding units: pattern - film covering equipment - film stretching plate - molding sand bank - vibrated table - empty box turnover machine - drying equipment - sand box - manipulator and others
Sand processing units:shakeout grille - vibrating conveyor sand machine - magnetic separator - boiling cooling classifier and others.
Sand Box used in Vaccum process castingÂ
V method sand box contains side exhaust filter type, perforated  pipe perforated pipe filter type, side suction combined type and vertical molding pouring type etc.
PROCESS:
pattern-film heating-film forming-film coating-flask setting-sand filling-top film forming-pattern suction/pattern draw-mould closing/pouring-mould releasing
ADVANTAGES:
-Manufacturing of castings without burr, without draft and with minimal maching allowances.
-High reproducible demensional accuracy and excellent surface quality of the castings
-No pattern wear
-Suitable for all common casting metals
-Less sand loss and environment friendly technology
-Other individual reasons.

Deep Stamping Products, it can also be called Deep Metal Stamping Parts,Deep Processing Metal Stamping Parts,Deep Processing Stamping Parts.
The manufacturing process of stamping parts is stamping processing. Stamping processing is a kind of power by means of conventional or special stamping equipment, so that the sheet is directly subjected to deformation force and deformed in the mold, so as to obtain product parts of certain shape, size and performance. production technology. Sheet metal, mold and equipment are the three elements of stamping processing.
Stamping is a metal cold deformation processing method. Therefore, it is called cold stamping or sheet metal stamping, or stamping for short. It is one of the main methods of metal plastic processing (or pressure processing), and it also belongs to material forming engineering technology.
Dongjie can produce stamping parts according to your drawings. Dongjie has more than 1500+ sets of molds, and has a professional technical and design team. We can meet your requirements as much as possible. You are welcome to come to consult with your drawings .
