Clamshell Blog

1. Plastic clamshell products produced fused marks of reasons:
1) due to melting the material solidified in the confluence of spearhead part of the cooling of the fused strip without causing marks.
2) due to volatile materials, the air still blocked
3) residual cavity with release agent.
2. Associated with knowledge:
1) using a gate, without the direction of the material from the confluence of the two products generally do not have fused marks, in addition, if the Want to avoid changing the gate can only be fused marks the location of so fused marks are not visible, or appear to occur in the location of eyesore.
2) mold on the pins (in the product on the hole) usually occurs fused marks.
3) has been closed due to air arising from the phenomenon of fused mark is very large, it is necessary to make the air completely escape.
4) it also uses this method: To generate fused marks in a place where the extra sheets in the product, and then then slice Cut off.
5) release agent over molten material Ershi float part of the advance party sent to the cavity, melting occurs certain knot mark.
3. Solution:
1)An instant: Improving injection speed, mold temperature increased to raise the temperature of barrel increase injection pressure.
2)short-term: the increase of gas escape slot.
