These moulds are positive tools that will produce the intended item above where the clamps are positioned on the sheet of material. The costs of this method of tooling are typically cheaper than using female moulds.

Using this mould will usually make the visible surface of the product the top one. This will allow the thickness of the plastic to hide imperfections on the surface of the tool, therefore resulting in a higher quality finish.


These moulds differ from male ones as it will produce the product you are forming below the clamps on the sheet of material.

This type of tool is better for projects where you want to create sharp details. It can include things like corners and deep cavities. A female tool will also usually reduce the chances of webbing in comparison to using a male mould. In addition, the spacing is closer and can allow you to lower the costs for materials.
