Types of Molds for Vacuum Molding, Aluminum Casting, Die casting, Aluminum Molds, Aluminum Molding Making

There are many types of molds for aluminum casting that are used in casting molten aluminum into different shapes and forms. Some molds are temporary, and others are permanent and can be used repeatedly. These same types of molds are also used for many different metals and alloys besides aluminum.

Sand Casting Mold
The oldest types of molds for aluminum casting are the molds that have been used since the time of the Egyptians. These types of molds are made when a cavity is created in sand that is held in a box or "flask". Usually the original "pattern" is made out of wood, metal or other solid material. There is also a core in the sand cavity that forms the center of the casting. Of the different aluminum casting molds, this is one that is used especially for engine blocks, engine manifolds, and other large and heavy castings.

Ceramic Mold
Another type of casting mold used with aluminum and other molten metals is the ceramic mold. Used most commonly for the investment casting process, the ceramic mold is created around plastic or wax that melts when the mold is fired while it is being created. After the wax is "lost", the mold is then ready to receive the molten metal. This type of casting process is also called "precision casting" because of the precise castings that can be created with this process.

Permanent Mold Casting
Permanent types of aluminum casting molds are made from metals such as steel and iron. The molten aluminum is forced by gravity or a vacuum into the permanent mold cavity. One advantage of these types of mold castings is that the mold is permanent; unlike sand casting molds which are usually destroyed when extracting the castings once they have cooled. It is also less expensive when used for a large number of castings.

Die Casting Molds
Die casting molds use steel dies or molds to produce a lot of identical castings. With aluminum, as other metals, the molten metal is forced under high pressure into these types of molds for aluminum casting. This is a versatile process that enables the production of a large quantity of small to medium-size castings.

Shell Mold
A shell mold is a type of sand casting mold that uses resin to bond the sand into a thin, 10- to 20-mm thick, shell. While the use of these types of molds for aluminum casting produces a better surface finish with more accurate dimensions, this process is definitely more expensive.

Plaster Molds
Plaster molds are created using plaster slurry that is poured around wax or another type of expendable material such as foam. As the plaster mold is baked, the pattern melts out, leaving a perfect representation of the pattern. Molten metal is then poured into the cavity of the plaster molds. This is another form of "lost wax casting".

Graphite Casting Molds
Graphite molds and cores are often employed with aluminum centrifugal casting. This process forces metal into the mold and uses rapid chilling to produce a quality of casting not possible with other methods.


These are the seven types of molds for aluminum casting most commonly used to produce aluminum castings. Each casting mold is used to produce specific qualities and for different types of casting properties.

China Flocking packaging Manufacturer, Flocked Tray inserts, Flocking blister tray

Flocking blister packaging can be distinguish to three flocking way as below based on packing difference:

First, 

Flocking machine assembly line: it can finished flocking blister packaging shows on
coating.flocking,stoving,pont obliterated etc.full automatic process flow. Such as flocking
material,leather,paper,non-woven fabrics,PVC,PS,membrane sheet,sponge,various handiwork,toy,
Automotive plastic,store box,Automobile sealing rubber strip,panel,blister box,paper card,
calendar,antithetical couplet,new year picture,the flocking printing gift package box.

Second,
Box flocking: can be made a flocking carton according to the size and shape of the flocking
blister packaging products.Then put villus into the carton and switch on, show up a high-voltage
electric field in the flocking carton inside, and complete the flocking during three to five seconds through the flocking blister packaging products are send from one side of carton to inside,Then remove it from other side.and can processed to be flocking blister packing products after stoving or airing. 

Third. 
Switch on and generate thousands of volt high voltage static through the flocking machine. Output to work nozzle inside, the villus of nozzle with negative charge, then put it to the planted surface coating adhesive sticker. Move nozzle and close to flocked products, the villus will remove from nozzle to planted surface under high voltage electric field and plant on the object surface with coating adhesive sticker in vertical way.
The application of Flocking blister packing products and other material flocking products are wildly

used in different field, such as:
1.packaging: jewel box.health products packaging,wine box, glasses box, marriage certificate,
  high level certificate skin,wine bottle,bag,adhesive sticker,paper sheet(card) etc.

2.auto field: automobile rubber seal strip,Car flocking interior etc.

3.artware: various toy, artware, photo backplate,gifts,Process calligraphy and painting,
  artificial flower,artware plastic lantern etc.

4.resin,ceramic,gypsum,glass,plastic,recycle plastic artware,toy flocking skin.

5.relative field: motorcycle helmet,coat hanger,fireproof door, safety box,lighting, kitchenware,
sanitary fittings, furniture,sponge,EVA, hanger with different material and so on.

Thank you for your reading, we will try to help you if you have any questions.
