Balancing with the Smallest Pitch Dimension
In a mold for small parts the pitch dimension of the hot runner tips determines the mold size. To reduce the size it is necessary to screw the tips directly into the manifold. […]
The Influence of the Temperature Profile to Part Quality
The degradation of the material depends not only on the dwell time, but also on the temperature profile of the hot runner components. […]
Do a good Mold Design for Mini Hot Runners
As previously mentioned, reduced heat transfer into the mold can be achieved by minimizing the contact surfaces between the mold and hot runner. […]
What is Direct Methods of Rapid Tooling?
All of the previous methods of rapid tooling involve the indirect production of a master pattern from which the tool is produced. […]
What is Direct AIM tooling?
Rather than making a master stereolithography pattern around which a material is cast, it also is possible to build the cavity directly on the stereolithography machine. […]
What is SLS RapidSteel?
In the same way that a cavity can be generated directly by stereolithography, it also is possible to build tool cavities directly using the laser sintering process. […]
introduction to Copper Polyamide Tooling?
The Copper Polyamide tooling process from First-rate Mold Solution Co. Ltd involves the selective laser sintering of a copper and polyamide powder matrix to form a tool. […]
What is Direct Metal Laser Sintering?
Direct Metal Laser Sintering (DMLS) from EOS involves the direct processing of metal powders in a laser sintering machine. […]
What is Laminated Tooling?
Laminated tooling is an alternative to building cavities directly on an RP machine. Using the similar principles to the Laminated Object Manufacturing (LOM) process, layers of sheet metal are cut to replicate slices through a CAD model. Laser cutting or water jet technologies generally produce the profiles. To produce a mold tool, the CAD model [...]
What is LENS?
The Laser Engineered Net Shaping (LENS) system from Optomec (Albuquerque, New Mexico) -originally developed at Sandia National Laboratories – builds parts using a metal powder feed into a laser, […]
