1st area to focus on

“The message? Get tooling design as efficient as possible to decrease tooling turnaround times. Then you can differentiate yourself with services”



Strengths of NX Tooling & Fixture Design

Strengths of NX Tool Design

1. Embedded process expertise

2. Re-use of company standards

3. Design validation

4. Integrated solution

Best in class performers are:

• 56% more likely to adopt CAD with automated capabilities

• 2x as likely to capture tooling design knowledge

• 30% more likely to simulate the tooling in its manufacturing environment

• 45% more likely to manage tool designs with PDM.




“An automated system will walk you through a series of discrete steps to complete the mold design.

……for an inexperienced designer, it’s like having someone looking over your shoulder who tells you the next thing you need to do.

…And for someone with a lot of experience, it relieves much of the tedium; so you can concentrate on designing instead of operating a piece of software.”

“NX has an obvious advantage over its competitors in modeling strength and open architecture, so any solution built on NX will already have a great advantage over others, the NX Progressive Die Design taps into advanced modeling functionality.

On top of that, it delivers unmatched intelligence for automating die design processes. Between the two integrated programs, you get an unbeatable combination.”

“Implementing a strategy for capturing & reusing knowledge in the form of standard parts and mold/die bases can eventually result in tool design lead time reductions of up to 40%.”

Greg Nemecek, Systems / UG Administrator, General Die & Engineering, Inc

Capture Reuse



Design Validation- design error reduction

Fatal Problems Prevent the tool from producing an

acceptable part during the tool trial Require significant rework of tool

designSlight Problems Cause significant delays in the

manufacturing process Result in some rework after the tool

has completed trialCareless Mistakes Require minor rework Cause minor delays in the

manufacturing process

“Huge costs for unnecessary and time-consuming corrections arise through small violations of certain construction principles and rules during the design phase.

NX Mold Design virtually eliminates such violations, saving significant time and money.”

“Hofmann needs to identify interferences early in the design cycle…

NX Mold Design provides effective tools for early design confirmation with parting check and tool design validation.”

“Our company’s goal is to deliver on time, within the budget and with 100% quality. Software from Siemens supports this by using built-in intelligence and excellent visualization to speed die design.

Quicker die design allows WTW to answer the industry’s demand for faster, more complex tool design.”

Integrated Solution

“Revision control was our biggest problem in the past. When we had the different departments working with different software, it was very hard to ensure that everyone was working with up-to-date information.

With Teamcenter, we have a tight system of revision control. Between that and the single source data model approach, everyone is accessing up-to-date geometry in real time.”
