Highly qualified engineers require outstanding tools – VTC has the most sophisticated and proven software tools and simulators for electrical design. We use CORET for our main electrical design and further fine tune the design using various state-of-the-art digital simulators.

The table below provides a glimpse of CORET 3 and Seitlinger digital simulators – both tools are handcrafted over 30 years.

At VTC, we use state-of-the-art mechanical tools with full automation capability to eliminate design errors.

Process New

We employ an engineering process that ensures perfect coordination between the various groups – electrical, mechanical, controls, and manufacturing.

Our engineers utilize a five-step process to ensure optimum design. Complete compliancy in every step of the process is required for flawless engineering. It begins with the supervisor signing off on the conceptual design, followed by a handshake agreement between the electrical, mechanical, and controls groups. Each group develops detailed design plans and meet with the manufacturing technicians to solidify the design. The design is presented to the shop floor supervisors and becomes official.

Every unit is custom designed based on customer specifications and requirements using our internally-designed programs. After the initial design, safety factors are added to account for manufacturing tolerances and to minimize the risk of failures. Our added safety factors are based on over 50 years of experience.

Designs are checked using sophisticated analytical simulations to identify stress 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.

We believe in sharing our knowledge and expertise to educate and guide our customers in the right direction.
