A Study on Computer Simulation of Plastic Lens Molding Process
In this paper, some molding process parameters such as injection time, packing time, packing pressure and process temperature etc. were optimized by the Computer Aided Engineering (CAE) simulation (Moldex 3D) for injection molding of a plastic lens. Some experimental trials were carried out for verifying of the CAE simulation results with checking of the lens shrinkage and birefringence etc. as...
متن کاملDesign and Simulation-Based Optimization of Cooling Channels for Plastic Injection Mold
Injection molding has been the most popular method for making plastic products due to high efficiency and manufacturability. The injection molding process includes three significant stages: filling and packing stage, cooling stage, and ejection stage. Among these stages, cooling stage is very important one because it mainly affects the productivity and molding quality. Normally, 70%~80% of the ...
متن کاملProcess planning for rapid manufacturing of plastic injection mold for short run production
This thesis presents a process planning methodology for a rapid injection mold tool manufacturing system that involves additive and subtractive techniques, whereby slabs are sequentially bonded and milled using layered tool paths. Mold tools are grown in a bottom up fashion, eliminating the need for multi-axis machining operations (beyond three axes) and allowing small features in deep cavities...
متن کاملEffect of Zr Addition on Mechanical Properties of Cr-Mo Plastic Mold Steels
We investigated the effects of the additions of Zr and other alloying elements on the mechanical properties and microstructure in Cr-Mo plastic mold steels. The addition of alloying elements changed the microstructure of the normalized samples from the upper bainite to lower bainite due to the increased hardenability. The tempering temperature influenced the strength and hardness values, especi...
متن کاملDevelopment of Embedded Metal Lines in a Plastic Electrochemical Microfluidic Device by Blanket Mold Imprinting
In this paper we introduce a blanket mold imprinting process to prevent complication of the fluid flow and difficulties in producing high pressure seals. Inchannel embedded metal lines were also fabricated within the channel allowing electrochemical detections of analytes. Electrochemical microfluidc device has been fabricated on the PET (Polyethylene Terephthalate) substrate by using imprintin...
