Design Section
Our internship started as we enter into design section as the design is considered as the first step of any production and it display the end result before wasting material and it’s the best tool to communicate with your shop men, technician and others, so it compulsory to have basic knowledge of design for everyone.
In design section you deal with the language of lines how they represent the end results of your dedicated work. We were first diverted to drafting then to proper design process

The design section is based on three steps

Sketching
Manual
Computer aided Design (CAD)

Wire EDM
Wire EDM machines imported from Swiss, uses wires of diameter ranging from 0.1 mm to 0.25 mm and EDM Drilling machines can do the drilling up to a diameter of 0.3 mm. Various grades of Steels, copper and carbides were also machined in these machines. These sophisticated machines process complex geometric shapes up to height of 150 mm.

Why EDM?

EDM can easily machine parts with very thin walls, complex geometry, narrow slots, small corner radii, very small features, etc. with virtually no mechanical stress.
EDM can cut hardened steel, titanium, Inconel and other difficult materials without the limitations of traditional machining.
EDM can achieve an excellent surface finish with no burrs right out of the machine.
EDM can reduce production costs with stacked parts machining using wire EDM as well as multi-up fixturing for wire, sinker and hole pop EDM.
Use EDM over broaching for better precision, accuracy and finish, no need to make a custom broach, and no risk of introducing unwanted debris into the finished part.
Use EDM instead of short-run stamping for straight-edge cuts with sharp corners and no shear or break as well as reduced costs by eliminating the need for special tooling.
