What is Dual-Rod Lifter Systems?
Use of a second guide rod parallel to the lifter core is a relatively new and under-utilized method. […]
What is Single-Rod Lifter Systems?
When designing mold cores for undercuts and side-action molding, the designer has several lifter system options. […]
Mini hot runner system is very useful
The injection molding of precision and micro parts creates special demands on the moldmaker and hot runner supplier. […]
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. […]
The fifth part of the guidelines of selecting CNC or rp
Staffing RP: MinimalWith the exception of secondary operations (benching), RP requires little labor. Within a few minutes, it is possible to prepare files for part production and start the build. During the build, there is little or no operator attendance. […]
The fourth part of the guidelines of selecting CNC or rp
Surface Finish RP: Ra 100 to 600 in. (2.5 to 15 microns)Without any secondary operations, some, if not all, surfaces will be rough. While RP has progressed to layer thicknesses of 0.0005 to 0.001 inch (0.0125 to 0.025 mm) for some technologies, the layer striations and stairstepping still affect surface finish. […]
the third part of The guidelines of selecting CNC or rp
Accuracy RP: 0.005 to 0.030 in. (0.125 to 0.75 mm)While it is possible to achieve dimensional accuracy better than 0.005 inch (0.125 mm) on individual dimensions, 0.005 to 0.030 inch (0.125 to 0.75 mm) is the typical range of deviation. Accuracy is a function of the RP system and the size of the dimension. As [...]
the second part of The guidelines of selecting CNC or rp
Part Complexity RP: UnlimitedIf a prototype can be modeled with design software, it is possible to build it with little impact on time or cost. The ability to quickly and cost-effectively produce complex parts is one of RP’s biggest benefits. […]
