HWI's mechanical engineering team has broad experience in mechanical design across many industries. They use advanced tools like 3D modeling, finite element analysis, and dynamics analysis to develop innovative, manufacturable product designs from idea to realization. Their concurrent engineering approach integrates mechanical design with other disciplines. HWI's mechanical engineers leverage their expertise in areas such as structural design, electro-mechanical systems, electronics packaging, and custom prototyping to provide evaluative contributions that improve product designs.

MECHANICAL DESIGN ENGINEERING
Experience Makes The Difference
HWI’s Mechanical Engineering team has a broad range of
experience across various product types and industry
segments. Provided with advanced tools and hands-on
knowledge and talent, HWI’s Mechanical Engineers strive to
develop products embracing a concurrent engineering
perspective. This means our development is not done in a
vacuum and then tossed over the wall, but is an integrated
effort with all other design teams, ensuring process flexibility
to adapt to input as necessary. Our experience includes
structural design, mechanism design, packaging, electro-
mechanical design, micro-miniature design, optical/laser
Dynamic Modeling applications, industrial design, and cast, machined and plastic
This solid model, created in part design. HWI also uses advanced testing methods such
SolidWorks, shows the various
components comprising the final as Dynamics Analysis and Finite Element Analysis (FEA),
assembly. This 3-D modeling which includes stress, vibration, buckling and heat transfer
simulation allows us to perform
“virtual concurrent engineering”, analysis
verifying the fit between the 294
electronic and mechanical
components and sub-assemblies Design Innovation
before expensive prototyping begins.
An innovative design approach is required to meet today’s
ever-shrinking product packaging requirements. HWI’s
experienced Mechanical Design personnel use a combination
of sophisticated tools and broad applications knowledge to
develop custom solutions for each customer project. HWI’s
cross-disciplined concurrent engineering approach ensures a
strong, manufacturable, regulatory compliant, “real-estate”
efficient product for our customer.
Integrated PCB Design Stress Analysis
Integration of the PCB design into the enclosure at Through the use of advanced
an early stage reduces design time and costly computer simulation tools, HWI
mistakes. Mechanical Engineers perform
detailed stress analysis to
predict potential component
failures and prevent product
design defects.
