This document describes a project to improve the ejection system of an injection molding machine to increase productivity. The existing system uses two ejectors but takes a long time (80 seconds) per cycle. The proposed new system adds two additional ejectors on the front corners. This allows the molded component to be ejected with only one stroke, reducing the cycle time to 54 seconds. Calculations show the production rate increased by 48% with the modified system. Benefits include balanced ejection, eliminating component catching issues, and improved part quality. The objectives are to reduce ejection time, cycle time, and improve production rate and efficiency.

DESIGN OF MOULD TOOL & COOLING CHANNEL OPTIMIZATION OF REMOTE CONTROL TOP PANELIjripublishers Ijri
A plastic material is any of a wide range of synthetic or semi-synthetic organic solids that are moldable. Plastics are
typically organic polymers of high molecular mass, but they often contain other substances. They are usually synthetic,
most commonly derived from petrochemicals, but many are partially natural.
Molding is the process of manufacturing by shaping liquid or pliable raw material using a rigid frame called a mold or
matrix. This itself may have been made using a pattern or model of the final object.
Cooling channels are used in mold tool to reduce the temperature of the object to help molten material to solidify quickly
before the ejection. It is quite useful to increase the production rate.
The aim of this project work is to design mold structure and optimize cooling channel system to reduce effect of warpage
of remote control top panel.
This project deals with the modeling of cooler tank parametric model as per the client requirement. Finding the best manufacturing process preparing mould base for the same, analyzing different manufacturing process by doing CNC program by changing milling parameters (feed, speed, cutters….).So that optimum parameters for manufacturing will be suggested which is useful to reduce the costs and efforts. Plastic flow analysis will be conducted to check the material flow and filling. So that reduction in the pre-machining cost will be done by rectifying the problem. FEM Based analysis will be conducted on mould structure to reduce weight of the mould. And thermal analysis will be conducted to suggest optimized cooling channel design. Modeling, mould base preparation, manufacturing, cnc programming will be done

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
