ELECTRICAL TOOLS

Outstanding engineers require outstanding tools – We have the most sophisticated and proven software tools and simulators for electrical design. We use CORET and VTCW for our main electrical design and then we further fine tune the design using various home grown and off-the-shelf state of the art digital simulators.

A glimpse of CORET3 and Seitlinger digital simulators – both tools are home grown over 30 years.

MECHANICAL TOOLS

Outstanding engineers require outstanding tools – We ALSO use state of the art mechanical tools with full automation capability to save us time and eliminate design errors.

PROCESS

Process New

With good engineers and good tools, one needs an engineering process that ensures perfect coordination between various groups – Electrical, mechanical, controls and at the end, manufacturing.

VTC – GTC uses a five-step process:
Step 1: Is a conceptual design signed off by the supervisor.
Step 2: Is a handshake agreement between three groups; electrical, mechanical, controls while sales is also part of this step.
Step 3: Detailed designs are then developed by each group.
Step 4: Is this design buildable, manufactural, what is the impact on manufacturing?
The entire engineering team gets sits down with the manufacturing technicians to come to a
consensus, unanimous agreement on the design.

Step 5: Manufacturing
Before releasing it to the floor, the combined team will discuss with the actual shop floor supervisors (step 5) who have a physical feel for one design based on their years of experience. This is where the design is official.

DESIGN PHILOSOPHY

Every unit is custom designed based on customer specifications and requirements using proprietary design programs.

After initial design, safety factors are added to account for manufacturing tolerances and more importantly to minimize the risk of failures.

These safety factors are based on over 40 years of experience. Over compensating will result in insufficient, expensive designs and going the other way will obviously increase the risk of failures.

Designs are checked using sophisticated analytical simulations to identify tress concentrations.

Designs are fine tuned to distribute these stresses to further minimize the risks.

In addition, over 15,000 archived designs are leveraged to benchmark new designs.

Finally, we believe in sharing our knowledge and expertise to educate and guide our customers in the right direction.
