Stripping reasons for the difficulties

Stripping reasons for the difficulties

A mould from the groove
2 stripping slope less than
3 mould finish is not high

II. Related Knowledge

1 As the stripping slope failure caused by lack of very common during the product design, mould must be marked in surface slope, stripping slope is usually in the range 1 to 2 degrees, in this context much good as far as possible, allow for special occasions, more than 0.5 degrees
2 If the injection pressure is too high, products closely aligns with the mould too closely, it becomes difficult to mould
3 in order to successfully make the products from the mould, silicone mould release agents containing generalists, but only when using a thin coating of release agent layer. If the coating is too thick to wipe hard. Well as release agent to the role of the print markings on the products of secondary processing becomes very bad, once the coating on the mould release agent attached to the products on the wipe is quite difficult to think of.

III. Solution

An instant: decreased injection pressure, shorter dwell time, lower temperatures reduce the ejection speed of the mould, spray release agent
2 Short-term: to improve the finish of the mould cavity
3 Long-term: increase the stripping slope, increase the number of ejection pin

IV. Material Differences

1 is heavy and hard materials, such as GPPS, due to lack of slope hat thing common cause product damage. Of both sticky and soft materials like PE, has the potential to block the root of certain products were cut
