The document provides an overview of PTC Creo Mold Analysis Extension (CMA). It discusses current challenges in injection molding processes that lead to high costs. CMA provides injection molding simulations within Creo to validate part design, optimize the mold design, and improve molding processes. It features an intuitive interface and identifies potential filling issues and recommendations. CMA is integrated with Creo and provides accurate 3D simulations to reduce costs from mold rework.

AGENDA

3. 3
Products and their
corresponding tooling are
getting more complex
CURRENT PROCESS CHALLENGES
Tooling Market Trends
• Teams, data and processes
span business and geographic
boundaries
• Need to be right the first time
with expected quality
• Need to formalize and reuse
design and manufacturing
knowledge
• Need early involvement with
customer
Tooling Design and
Manufacture
Relentless price erosion and
increasingly
shorter cycle-time
• Tooling is typically on the
critical path of any new
product introduction
• Need to respond very quickly
with accurate quote
• Massive pressure to reduce
tooling design and
manufacturing lead time
• Increased global competition
• Need to accept changes late in
the cycle
“ Mold and die shops identified price competition as their top business pressure …
… despite the fact that the products and the corresponding tooling is only getting more complex”
From “Aberdeen Group, The 21st Century Mold and Die Shop”, April 2007

4. 4
• Increased time to market
• Extensive mold debugging trials
• Costly mold rework
• Excess material usage
• Poor molded part quality
CURRENT PROCESS CHALLENGES
Lots of costs because plastics parts are not optimized for the injection molding process…

What is PTC Creo Mold Analysis Extension (CMA)?

7. 7
• Allows customer to quickly and accurately analyze and optimize not just every design but every design
iteration
• Enables Design Engineers to gain insight into the Manufacturability of their Designs
– Will it fill?
– Where are the weld lines & air traps?
– Which material?
– Gate location?
– How to size geometry for optimal manufacturability?

Why PTC Creo Mold Analysis?

8. 8
• Intuitive, process-driven UI
– Quickly learn how to build molds leveraging process-driven UI
• Optimization of Plastic Part
– Determine potential part defects such as short shot, weld lines, air traps, and sink marks.
• Optimize Injection Molding
– Molding condition
– Gate location
• Injection Molding Simulation
– Quality Prediction
PTC CREO MOLD ANALYSIS EXTENSION
What does PTC Creo Mold Analysis provide?

9. 9
• Because of the high cost of injection molds (>>$10,000) and the low cost of Creo Mold Analysis, the
customer’s ROI can usually be achieved on one project.
• Allows customer to quickly and accurately analyze and optimize not just every design but every design
iteration directly from within Creo.
– Best CAD-integrated
– Provides unique on-line advice
– Extremely easy to use
– Extensible Solution Depth

COMPARISON TO MOLDFLOW PLASTICS
ADVISER

28. 28
PTC CREO MOLD ANALYSIS VS. PLASTIC ADVISOR
PTC Creo Mold Analysis Plastic Advisor (Moldflow)
Mesh preparation Automatic full 3D mesh generation Dual Domain (DDT) mesh. Manual mesh
density adjustments are necessary
CAD supports STL or boundary mesh STL or boundary mesh
Solver True 3D solvers Performing 2D analysis on opposite
surfaces then synchronized artificially
Speed Moldflow is generally faster as it’s 2.5D
Accuracy CMA is more accurate as it’s 3D. Strange melt front can be predicted by
Moldflow/Fusion if the part geometry is complex.
Fiber CMA is more accurate as fibers usually show strong 3D orientations
Warp PTC Creo Mold Analysis is more accurate as it’s 3D
General comments  Dual Domain technology only excels if the part has uniform thickness and
very few ribs/bosses.
 More and more products are designed with very variable wall thickness. It’s
essential to run 3D analysis on most parts.
 PTC Creo Mold Analysis is more accurate when integrating with structural
analysis, especially for fiber-filled materials.
