Although high aspect ratio micro and nanoscale polymer features have been replicated in a range of polymers using injection molding, researchers have also used tooling inserts with a range of sizes, aspect ratios, and tooling materials. In this work, microscale features with molded in polymethyl...
Limited material option: 3D printing is currently limited in the types of materials that can be used, although this is rapidly changing with advancements in technology. Lower accuracy and surface finish: 3D printing may not be able to achieve the same level of accuracy and surface finish as mo...

CNC machining and injection molding are two common ways to make actual products in different industries. In CNC machining, manufacturers use metal cutters to remove unnecessary materials from the final product, whereas, in injection molding, liquid plastic is shaped in mold form to produce the final...

up to 40% of the material in the traditional cutting process will turn into chips, while 85% of the powder used in powder metallurgy is produced from recycled materials. In the production process of powder metallurgy parts, the waste loss of each process is generally 3% or less, and the ...
Metal injection molding is an effective method for high volume production. The finished MIM parts have smoothness surface finish with relative strength. MIM technology is compatible with a wide range of metal materials, these are mostly steel. MIM materials are in powder form and suitable for sinte...

A detailed introduction to the MIM process can be found byGerman (1997). The first step in the process is the homogenisation of the starting materials, where a binder material is added to the powder. Normally at least two binder components are employed. After the homogenisation in a heatable...
It was possible to run a stable injection molding process with the developed thermoset-specific mixing element. In comparison to the conventional conveying screw geometry, the process value scatter, both during the injection and the plasticizing phase of the process, is reduced. The reduced process ...
