Manufacturing Feasibility Analysis
Every new project begins with a
manufacturing feasibility analysis. The part
model is examined to ensure the part has
sufficient amounts of draft so the part will
release properly from the mold. Part features
which could cause premature steel failure
are identified and communicated to the
client. Undesirable cosmetic issues are
reviewed. 2D drawings and 3D model files
are compared for compatibility. Modifications
to the part model needed for
manufacturability are reviewed and included
in the quotation. All potential product design
improvements are discussed with the client
prior to starting the project.

Gate location and runner size is determine for
best filling and packing pattern
Uniform and balanced cooling schematic is
developed for turbulent flow characteristics
Knit lines, flow lines, sink mark are identified
Air trap analysis show areas needing venting
Shrinkage values are defined
Warpage potential is compared to 2D drawing
specifications and requirements
Initial processing parameters are charted
What-if simulations are used to optimize the
process and part geometry

Tooling DFMEA
• Technical tool design review process is
based on a tooling DFMEA. Every
potential failure mode is identified and
designed out.
• Process begins with the mold ready to
load into the press and ends with good
part in the box.
• Process considers press and process
compatibility, mold integrity and
reliability items, as well as all major mold
systems and components.

EOAT (End-of-arm Tooling)
• EOAT based on tool design
• Plastic fixture plates that are both
conformal to part and breakable in crash
situations
• Plastic fixture plates are about 1/3 the
weight of aluminum
• EOAT finished when mold is T0 sampling
