ESI Customer Hwaseung R&A Manages Product Reliability while Cutting Development Time and Costs


The Korean automotive supplier leverages the power of ESI's Virtual
Prototyping platform

(Paris:ESI), leading innovator in Virtual
software and services for manufacturing
industries, announces the successful application of virtual prototyping
by Hwaseung R&A, Korean automotive supplier specialized in high & low
pressure hoses and weather strips. Using the automation of trunk joint
simulation processes in
, the equipment manufacturer was able to
correct seals defects and improve their design, while reducing
development time and costs.

Hwaseung R&A, a company supplying automotive and other industrial rubber
parts, faced a trunk seals issue that needed to be corrected, as it
became deformed or distorted at the corners after assembly. The function
of a trunk seal is to absorb vibrations and to close the gap between the
vehicle body and trunk assembly. When the seal has an irregular shape
the pressure on trunk panels is non-uniform, which degrades their
ability to control of noise and water leakage can result in failure of
trunk panels.

Hwaseung R&A's engineers looked to simulation to address their design
problems and wanted a fully automatic model creation process. Their
research led them to ESI's Virtual Prototyping solutions and
specifically ESI
, a platform for Computer Aided Engineering (CAE)
and simulation process automation. Working with ESI, the Hwaseung team
was able to build an automated process that reduced model creation time
and facilitated performance evaluation. The process they developed uses
Computer-Aided Design (CAD) geometry, product design and modelling
parameters to build ready-to-run 3D models automatically. Using this
process, the Korean company was able to set up parametric studies that
allowed them to quickly experiment with different positioning
methodologies for thread and ribbed shapes, as well as other sectional

Thanks to the solution built on ESI's Visual platform, Hwaseung R&A
engineers are now able to virtually simulate the assembly of the trunk
seal and evaluate its performance without using real prototypes. Chang-Soo
, Deputy Manager at HWASEUNG R&A Corporation, stated "The
custom-tailored process automation built in ESI Visual-Environment made
trunk seal assembly simulation possible. We are now able to analyze the
contribution of steel insert design changes using a trunk seal assembly
process simulation. The solution we have built using ESI
Visual-Environment is fully implemented in our production process and is
used as the main tool to decide of design parameters at the initial
stage and also for solving problematic issues in production."

Not only was Hwaseung R&A able to correct the trunk seal defects and
reduce their development time and costs, but the process automation in
Visual-Environment was so successful that it is now implemented as a
standard in their design process for trunk and body seals. Today, they
are also using the solution to assist building models of trunk and door
