Metal 3D printing nowadays is a great complement in injection molding. 3D digitizing and printing allows for design and manufacturing molds with complex conformal cooling channel. This can reduce scrap, improve quality of parts and increase the cooling efficiency. Eplus3D provides a complete solution from 3D design to 3D printing for molding applications, dramatically increasing productivity.

Metal 3D printing VS. Traditional mold manufacturing


Traditional cooling channels /Conformal cooling channels
In the production of traditional molds, drilling can only produce straight waterways, which means that the shape of the waterway is limited and far from the surface of the mold. While 3D printing enables precise complex lattice and waterway construction. Designed in CAD software, the distribution of waterway is based on the geometry of the parts.

Compared to the traditional mold, 3d printed mold with conformal cooling channels have a higher heat dissipation efficiency, shortening production cycle and improving production efficiency.

The parts are often easily bent and deformed due to the high temperature in traditional manufacturing. With the uniform hear dissipation of the waterway, the 3d printer mold can manufacture zero-defective products, effectively improve product quality and reduce scrap.

3D digitizing and 3D printing enable a lightweight construction of the mold and reduce costs. At the same, bridging mold can be design and manufactured based on the existing mold through 3D digitizing and printing technologies.

Workflow:
Mold design
CAD design mold in SIEMENS NX software.




Simulation
Using NX’s simulation module to generate the analysis of molds’ waterway scheme, simulation of temperate change in the mold cycle. Based the result, optimize the design.



3D Printing
Using EP-M250 metal 3d printer, with up to 262*262*350 mm 3 building volume and high-precision printing, to manufacture high-quality the conformal cooling waterway molds


Metallographic analysis
Samples were taken for metallographic analysis to ensure that the print molds met quality standards.


Post-processing
Post-treatment such as heat treatment, de-support, surface treatment, etc.
