Variable mould making frame made of aluminium, consisting of: 4 aluminium angle plates, dimensions 100 mm x 200 mm x 50 mm 1 aluminium base plate, dimensions 200 mm x 200 mm
The 4 angle plates can be variably shifted against each other, so that a variable pouring box can be exactly adapted to the model. You get an optimal framing to use only the really needed amount of moulding material / casting material.
It has proven to be practicable to first apply a layer of non-hardening modelling clay, e.g. our TFC modelling clay. For example, our TFC modelling clay, as a base on the base plate and rolled out in the manner of a cake dough. The model to be moulded is worked / modelled into this base. This ensures that the model adheres to the base, no silicone runs under the model and the model cannot float in the poured silicone. You can press some depressions into the modelling clay, e.g. with a pencil, the head of a screw or a small ball. The depressions are then filled by the poured silicone and later serve as tongue and groove for the exact connection of both mould halves.
Only now, when all work for modelling in is completed, are the wall plates adapted to the model as desired and pressed into the base of modelling compound. This automatically creates a lower seal so that no silicone can flow out.
The remaining gaps between the wall plates should be sealed with modelling clay to prevent the silicone or casting compound from leaking.
After curing, the individual plates can be removed very easily, as materials such as silicone rubber or casting compound can be easily removed.materials such as silicone rubber or casting resin adhere very poorly to the aluminium and the mould frame and base plate do not need to be pre-treated. This is a decisive advantage in contrast to mould frames or casting boxes made of wood, as it makes removal much easier.
The individual parts are easy to clean and can be used again and again, unlike untreated wooden frames, which are either glued or have screw connections that are difficult to clean.
Aluminium base plate measuring 20 x 20 cm is supplied.
Should it be necessary to enclose larger objects, the plates of several mould frames can be joined together to form a larger casting box without any problems.
The transitions should then be sealed with modelling compound to prevent the casting compound from leaking.
Note Due to the manual machining process during manufacture, scoring or grinding marks may occur when bending the angles . This is normal and does not signify a defect - the functionality is not affected by this. You will always receive a new, unused mould frame.
Not a toy! Not suitable for children under the age of 14!
