Industrial Visit at “IDEMI (Institute for Design of Electrical Measuring Instruments)”

Introduction:

Department of Mechanical Engineering, Pillai HOC College of Engineering and Technology arranged one day Industrial Visit for 4th Semester Degree Students to “Institute for Design of Electrical Measuring Instruments”, Mumbai dated 28th March, 2024 for technical knowledge enhancement and practical exposure to students.

Objective of the visit:

It’s mentioned in the syllabus of Skill based Lab: CNC and 3-D printing, it’s necessary to give practical exposure to the Students of Semester IV regarding CNC machines and 3D printing. The objective of this industrial visit is to bridge the widening gap between theoretical learning and practical exposure by giving students first-hand exposure to different machines. This experience can help students to get information regarding the functioning of various industries and associated problems.

Company Profile:

IDEMI is an Organization established by the Government Of India Society in the year 1969 as a service to Instrument Industry Organization. The main objective of setting up this Institute was to gear up the growth potential of indigenous instrument industry and hence to meet the ever growing instrumentation needs of the country by augmenting productivity quality control in the industrial sector – be it in Electrical, Electronics or Process Control Instruments. The Institute is looked upon as a nodal Centre in view of its multifarious activities offered to suit various needs of the instrument industry.

Content:

On 28th March, 2024 students reached IDEMI (Mumbai) by 11.00 a.m.. After entering the institute, Industry Coordinators first took us to the Presentation room where they gave short information on what we will be learning today and gave safety instructions. Then, they divided students in 3 groups having 8 to 10 students and allotted a separate coordinator for each group.

Introduction and Presentation

Total of 5 sections shown in the visit:

• Designing Lab: In this lab, students saw how the designing process is done on different software’s, and then showed some prototypes of air gun, paint spray and oil casing. Showed how a model of face is made by scanning a real person’s face.

  Software used: SolidWorks, Catia, etc.

• SLS & SLA Lab: In this lab, the SLS (Selective laser sintering) and SLA (Stereolithography) printers have been shown, also shown some prototypes made on those machines.
  Material used: thermoplastics, powdered metal, resins, etc. Machine internal temperature: 15 C (-170 C)
  Software used: Materialise Magics
• EDM (Electrical Discharge Machining) Section: It is divided in two parts;
  1. Wire EDM Machine:
     Machine used: ONA AF35 WIRE EDM MACHINE Wire type: Hard Brass wire, Zinc coated brass wire
