For this reason, it is essential to draw up a customised maintenance plan and to optimise the life of the mould.<\/span>\u00a0<\/span><\/p>\n

In this article we have pulled together 5 questions we frequently receive from our customers.<\/span>\u00a0<\/span><\/p>\n

1-What is the best method to open a mould?<\/span><\/b>\u00a0<\/span><\/p>\n

Many moulders mistakenly use a chisel. In fact, this method causes abrasion to the mould\u2019s surface and the resulting material loss could easily produce an increase in the thickness of the final article.\u00a0<\/span>\u00a0<\/span>[\/vc_column_text][mk_image src=”https:\/\/www.ocs-stampi.it\/wp-content\/uploads\/2021\/10\/immagine1-1.jpg”][\/vc_column][vc_column][vc_column_text css=”.vc_custom_1636104058238{margin-bottom: 0px !important;}”]Levers are the right alternative to open the moulds without damaging them, preserving the surface for the next production cycle.<\/span><\/span>\u00a0<\/span>[\/vc_column_text][mk_image src=”https:\/\/www.ocs-stampi.it\/wp-content\/uploads\/2021\/10\/immagine3-1.jpg”][mk_image src=”https:\/\/www.ocs-stampi.it\/wp-content\/uploads\/2021\/10\/immagine4.jpg”][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text css=”.vc_custom_1636104169843{margin-bottom: 0px !important;}”]2- What are the typical defects caused by mould wear?<\/span><\/b>\u00a0<\/span><\/p>\n

Wear can be the cause of embrittlement in the mould. In fact, a worn-out mould makes the burr too thick on the moulded technical articles and, consequently, causes defects in the final piece.<\/span>\u00a0<\/span><\/p>\n

3- What is the cause of mould deterioration?<\/span><\/b>\u00a0<\/span><\/p>\n

Several factors lead to mould deterioration. The variables influencing the results are linked to both the mould and the polymer used.<\/span>\u00a0<\/span><\/p>\n

As far as the mould is concerned, deterioration can depend on:<\/span>\u00a0<\/span><\/p>\n
