There are many different types and grades of plastics available. The end use of the part can help determine the most suitable plastic for a given application.
Plastic injection molds can be manufactured from a variety of metal and metal alloys. The material properties of a range of different metals are listed in the Autodesk Simulation Moldflow material database so that the impact of the material that the mold is made is of can be taken into account.
Coolants are the fluids that flow through the cooling channels of a mold to extract heat from the system.
A filler is a material that can be added to a polymer for injection molding, to improve the quality of the part.
A MuCell® material is a gas, such as nitrogen or carbon dioxide, that is used in conjunction with the thermoplastics material in the Microcellular Injection Molding process.
Preforms are fiber materials that are manufactured for inclusion in plastic molding. Fiber preforms are often manufactured in sheets, continuous mats or as continuous filaments for spray applications.
Different materials can be used to attach a die to the pins on the leadframe. Traditionally the wires were gold.
Leadframes are used in semiconductor device fabrication to support the die during packaging. They are made of a conducting material and provide an electrical connection between the die which is encapsulated within a plastic material for insulation and protection, and the outside world.
