SelfLube is the leading U.S. manufacturer of precision components for Molds and Dies.
Molds and Dies are tools that cut and shape material and are in many ways similar. But what exactly is the difference? That’s a question with no simple answer, but we’ll do our best.
There are many different types of molds that can form products in a variety of mediums. Some of the materials that molds can form include:
SelfLube makes components for one type of mold: plastic injection molds. Such molds have an internal cavity that is the exact shape of the part (or multiple parts in the case of a multi-cavity mold). They are split in half so they can be opened and closed. When the mold is closed hot molten plastic is forced into the mold under high pressure. When it cools and hardens the mold opens and the part is ejected. The part could be a small toy or something big like the front end of a pickup truck.
Like molds, there are is a large variety when it comes to dies, such as:
At SelfLube, we make components for one type of die: metal stamping dies. Similar to an injection mold, such dies are split in half and have an internal cavity in the shape of the part to be formed. However, this is where the similarity ends. When the metal stamping die is open a thin sheet of metal somewhat larger than the finished part is placed in it. The die is then closed under great force. As it closes the thin sheet of metal is bent, cut and stretched to form the desired part. The die then opens and the part is removed. The parts that can be made from this process can range from a small kitchen item to the roof of an SUV.
