2. Details of Industrial experience:
I joined the industrial training at Ratan Poly Elastomers, on 15th of July 2018. The entire
industrial training program continued till 15th of January 2019. It was a six months industrial
training program. As a mechanical design engineer, I was working under a team that included 12
members working on a project for installing a sophisticated facility for manufacturing purpose.
The project included manufacturing of modern machinery and equipment in consultation with
the mechanical engineering designers. Thorough training was conducted with the group of well
qualified engineers based on different specialization such as technician, designers as well as
quality experts.

2.1 Background
The sole objective of the project of which I was a part, was to design a system that can be
used to mold the rubber parts in order to provide best sealing solution. In order complete with
our three dimensional mold design model, as a mechanical design engineer, I had to face with
reusability of different standard components of mold including geometric modeling and
assembling the complicated parts such as the mold base, ejectors, guild pillars and many more.
We integrated a database for the design of the rubber molds along with the module of the
construction of the molds into one single package. The standards parts of the molds are collected
in the form of library database in order to select them easily and assemble them during the
process of construction. The entire system was constructed using Auto LISP connected with the
Dialogue Control Box within the AutoCAD environment while preparing the integrated
CAD/CAM system for the molds.
The structure of the knowledge based system that was used during the initiation of the project is
as follows:

2.2 Engineering Activities
2.2.1 As one of the trainee under this Company, I was given the responsibility to design the
proposed system while coordinating with other members of the team. Since several technologies
as for example principle and analysis of mold design, applying technology related to
manufacturing is the sole requirement in developing rubber mold, hence I had to integrate the
fundamental principles with the target geometry part. The knowledge based system that is
proposed in order to account for the sub problems consisted of three main domains:
1. Domain knowledge: In this we used the Database storing all types of knowledge. It helped in
providing guideline so as to prevent the design from being conflicting with other design
constraints. There are various database management system available in the commercial market

7INDUSTRIAL WORK EXPERIENCE
such as Sybase, Oracle but My SQL is known to be the most easier one compared to its
performance. In our structure design we employed the My SQL 5.0.27 database in order to
manage the knowledge. Here the knowledge consisted of pre-molding process modules, layout
of the modules, cooling of the system, and many more. This knowledge is then transformed into
designing and manufacturing rules.
2.2.2 The first step to the initiation of the project included thorough review of research works
and going through various literature reviews. I applied the knowledge of mechanical designing
that I gained from my Bachelor’s Degree in order to relate the theoretical knowledge with that of
the practical doings. The entire project required the approval of design from the American
Bureau Shipping and hence all the rules and regulations that abides by it are studied thoroughly
connecting various elements of the design structure of the project.
2.2.3 The knowledge based system that I proposed in order to account for the sub problems
consisted of three main domains:
1. Domain knowledge: In this we used the Database storing all types of knowledge. It helped in
providing guideline so as to prevent the design from being conflicting with other design
constraints. There are various database management system available in the commercial market
such as Sybase, Oracle but My SQL is known to be the most easier one compared to its
performance. In our structure design we employed the My SQL 5.0.27 database in order to
manage the knowledge. Here the knowledge consisted of pre-molding process modules, layout
of the modules, cooling of the system, and many more. This knowledge is then transformed into
designing and manufacturing rules. Here I carried out the data analysis apart that served in

8INDUSTRIAL WORK EXPERIENCE
solving the problems that arises between the user and program interface. The rule that goes by it
is encoded using the PHP language.
2. Library: A library is used to hold information of the holds, their features, parts and various
supporting tools. Here the commercial 3D CAD system and SolidWorks 2014 is used in order to
provide a mold base library containing details of all the parts and assemblies of standard mold
design. The cavities that are located inside the work piece of the mold were thus formed by
extracting the shapes of the product models and were reserved in the CAD file.
3. Data: The typical reference of the data gathered included product materials capacities of the
molding machines, its tools and processes. The reference data was obtained from the process
itself and the rules can be derived from the modeling of the knowledge.
2.2.4 In the next step, I continued with the interaction process of the domain knowledge, its
library and the data. The application of the program was processed using web browser. The
processes that I used in order to set the rules in the application system included IF, AND, THEN
and ELSE. The cavity number was determined by activating the cavity layout determination of
the domain knowledge. The mold base containing the cooling system was selected from the
library. The dimensions of the product thus could be modified according ti the demand of the
clients.
2.2.5 The program was written using the Adobe Dreamweaver CS3 which is a type of
programming interface to the SolidWorks Autodesk Inventor. The application programing
interface or the API consisted of functions of hundreds of directives of the Visual Basic. Net or
the Visual Basic 6.0 or the Solid Work macro files. Implementing this within the structure design

of the proposed system enables users to directly achieve the use of SolidWorks functionality
such as creating line, extruding boss or verifying the parameters of surface. We then connected
the program to the internet using various domain. As a result of which, the web based link were
automatically connected to the server, eventually turning the database content in the server to
respond to the clients.
2.2.6 The rules of the production of the molds in building the system structure was represented
using the software via its input and output of the operation of the software. The various
information that were being used as a part of the input such as the number of cavity , its type on
top of the plate material, its dimension of the work piece and many more got checked and
verified. Converging all the cases within the dimension of the top plate was obtained from the
software that was used as a part of computing.
IF: Mold base = top plate
AND design < 4 cavity
AND dimension of work piece = 66.50 x 195.50 x 37.50 mm
AND type of material = S55C, S50C: ELSE type of materials DC 53.
AND machine capacity > 250 – 500 tons
THEN: Top plate dimension = 600 x 600 x 35mm

2.3 Technical and engineering problems and solutions
2.3.1 Problem 1: During the initiation of the project, unnecessary problems were faced based on
the designing of the rubber molds. This problem was solved while providing solution depending
on the questions asked during the analysis of data using the PHP script language.
2.3.2 Problem 2: A conventional design based approach was insufficient for processing with the
design technology and was critical to solve the design based problems. Here I made use of the
knowledge based engineering approach in order to cope up with the problem.
2.4 Creative Work
All the rules and guidelines that were required in order to gain permission about the
system design were read by me thoroughly. The rules and guidelines that goes by it were marked
and pointed out. Depending upon the implementation need of the system design, I created layout
of the design manually including process of interaction that was followed among various domain
knowledge and library data.
2.5 Engineering standards
All the standards of data were referred before I proceeded with the project. All the rules
of ABS were followed and the regulations were met for calculating all the geometric structures.
After successful generation of the system design, the developed systems were integrated with
different kinds of knowledge guided by the designing of the engineer and improve the efficiency
of the result in order to decrease the operation time to 47.92 percent.
2.6 Project management
As soon I was introduced to the team with whom I worked for, I greeted my team mates
and a meeting was held in order to discuss the sole objective of the project. There as a

11INDUSTRIAL WORK EXPERIENCE
mechanical design engineer, I conveyed my idea of the modeling system to the team and gained
approval from my team mates. Soon the project started, I arranged for different meetings in order
to assess the progress update and the efficiency of each and every phase of the project
deliverable. All possible problems that might arise during the process were figured out and
necessary solutions were also pointed out with respect to the proposed system. As I was the main
body within the entire team responsible for making and developing the system design, I also
carried out different meetings with the CEO and also tried to grasp the demands from the clients
and tried to incorporate it within my designing model. I also initiated communication with the
ABS team discussing the system requirements and the rules that our system abided with their
rules and regulations.
3. Analysis of the Industrial Experience
While taking up the industrial training at Ratan Poly Elastomers, I gained a lot of
knowledge on the practical application of the AutoCAD software along with the use of SOLID
WORK software. This was the first time that I made any design for the practical field and
implemented it successfully. The processes that included with the designing of the machine,
helped be to apply my theoretical knowledge with that of the practical application. The entire
training program increased my problem solving skill and also gave me ample experience on how
to handle problems while providing solutions efficiently and delivering the project within the
deadline.
