There are three main technical difficulties in two shot medical oxygen mask mold:
1.Shrinkage: The shrinkage of the first injection must be taken into account, and the resulting dimensional differences when closing. Deformations resulting from shrinkage must be controlled.
2.Venting: To ensure the second molding, a perfect seal is required but this can lead to burr problems.
3.Filling: The second injection is made with plastic that has little resistance to injection pressure of the second raw material. In some cases, the second injection can bend the plastic insert. It is then necessary to balance the injection or the position of the plastic insert.
