Composite tools have become a standard in many manufacturing industries, especially those that use metal and plastic. The process of creating composite tooling consists of several steps, each of which requires specific materials and molding equipment.
Resin, which is made from the sap of trees, is mixed with metal, plastic, and a liquid binder and then heated until they become solid. This mixture is then hardened through repeated cycles of heating and cooling. Once the resin has been hardened, it is usually painted with various colors. The resulting product is often called powder-coated resin.
Composite tooling made from resin is often coated with a thin layer of epoxy paint before it is ready for use. Epoxy is a hardener and is also added to the resin during the heat-treatment process. Other hardeners can also be added to tooling in order to increase the hardness-to-density ratio.
Tools made from polymer resins can also be manufactured by pressing the materials into molds, which is a procedure that shapes the parts, and used in a number of different manufacturing industries, including food processing, the automotive industry, and the plastic molding industry. The molds can either be created out of metal or plastic, depending upon what type of tooling is required.
Other types of polyester resins are used as filler materials in polyurethane pliers, screw gun parts, and other specialized tooling. Some tools can even be custom-made with polyester or resins added to them. Polyurethane resins are highly resistant to moisture and temperature, but are also highly absorbent and may form bubbles under pressure or when the tool is heated. These bubbles can then be released with a vacuum to prevent damage to the tooling.
Many companies use injection molding to create custom tools. This process involves using plastic tubes that are filled with the resin or hardener, and then the tools are pressurized and molded into the shape required. This is a relatively quick process that involves placing a series of plastic tubes on a rotating drum at high pressure until the tool is formed into the desired shape.
Some precision tools use die grinding tooling machines. It is designed to grind fine components such as die-cast parts or more fine tooling. The machine includes an electric motor that controls the rotating drum which can be programmed so that the speed of the drum changes during the process, to ensure that the parts are properly ground. Different machines include reciprocating die grinders, rotor die grinders, belt-driven dies, etc.
Tooling manufacturers often design their machinery so that it can perform the various processes needed to create specialized, precision tooling components. This equipment helps to make sure that the end product is exactly what the customer needs, and is built to last for many years. Composite tooling is typically purchased in order to create tools for specific tasks, and because they are unique, they are often very expensive.
