Prevention of webbing

admin — Wed, 13 Jul 2011 15:21:13 +0000

Webbing is prevented just by setting on the machine:

- reduce compression speed,

- prevent too fast cooling down of material.

Webbing is prevented by screens in the clambing frame:

- limit forming area, so that geometrical compression conditions will be more favourable, … so that the “initial tent” will be smaller.

Webbing is prevented by design change:

- apply larger radii on the upper side of the mould so that geometrical compression conditions will be more favourable,

- change mould is such a way that webbing looks like purposely implemented reinforcement rib,

- create more surface in the lower section on that the webbing area can be used up.

Webbing is prevented by changing the mould in the waste area:

- build up mould higher so that webbing will form in the waste area ( this is only possible if the coresponding section will be severed),

- tear webs apart.

This can be effected with 2 artificial elevations ( e.g. hemispheres ), one right and left each of the web.

Similarly successful might be a wide recess below the web.

Webbing is prevented by means of the pre-stretching plug:

- according to the basic principle: ” you may press small webs, you have to pull large webs”,

- the pre-streching plug must be propably used in combination with negative moulds, especially for long, negatively formed groove-like recesses.

Webbing is prevented due to heavy sagging:

- if the surface of a heated material is larger than the surface of the forming tool, there will be surface webbing. This is the case, when sagging is severe and the mould is flat,

- the solution is to mounth the mould at an increased height so that there will be a larger forming surface ( mould + increased height). It should be at least the size of the material surface generated by sagging.

Positive and negative forming

admin — Mon, 30 Aug 2010 09:13:37 +0000

During thermoforming process only one side of the processed material contacts the mould. Its shape and texture are therefore reproduced on the surface of formed sheet or foil.
Depending on the side of material that contacts the mould we deal with positive or negative thermoforming.
During positive forming the inside of the blister becomes an exact mapping of the mould shape because this side contacts the mould. In case of negative forming it is the opposite and the outside of the blister is reproduced on the surface of the sheet – foil.
Following issues should be taken into consideration when positive thermoforming is taken into action:
• Creation of shrinking effects in case of rectangular moulds, especially if distance between clamping frame and the mould is significant
• Development of chill marks on the edges
• Uneven thickness of the walls on blister rims
• Uneasy detaching of the blister out of the mould caused by small angle of the wall
• Too shallow areas (not completely formed) between the areas of multi-cavity blisters, whose reduction is possible only through employment of additional clamping frame
• Positive forms are usually cheaper to make than the negative ones
Following issues should be taken into consideration when negative thermoforming is applied:
• Development of thick rims
• Eden thickness of the walls aroung the rim
• Development of thin edges
• Easy detaching of the moulds with single forming areas
• Łatwy demontaż form o pojedynczych obszarach formowania
• Negative forms are usually more expensive to make than the negative ones
Most of the setbacks can be reduced or eliminated through application of appropriate mould production techniques as well as control of the thermoforming process.
