Female mold making


1: Before making, make sure whether to split the mold or not

Because some hulls have an undercutting position, one mold can not be completed, and some parts are separated for the convenience of making. For example, this piece of hull can not be divided into modules. After the hull is finished, the unnecessary parts are bonded with cardboard, as shown in the following figure:

The paper board will be divided into two parts, one half of which will be cut on the other side. The boat is divided into three sections, which is much easier than just one piece.


2: Some shrinkage occurs during the hardening of unsaturated resins

If there is only one piece without parting, there will be no problem. If there is parting, there will be problems. Because the left and right sides of the shrinkage are not the same, if there is no positioning, there will be left and right asymmetric displacement. You can use the small cardboard with beveled edges as the positioning purpose. When the two pieces of mold after the concave and convex position, there will not be left and right mold waste position problem, with the bevel side small cardboard.
