Sigmund Stacks Standalone

Product Overview

SigmundStacks is a Tolerance analysis software that enables engineers to evaluate, optimize and validate assembly build quality, relative to piece part tolerance and assembly process variation early in the development phase before design solidification and hard tooling procurement. SigmundStacks prevents costly tweaking delays at ramp-up as well as long-term variation problems.

  • Tried and tested in real world manufacturing industry.

SigmundStacks enables engineers to quickly and efficiently evaluate the one-dimensional (linear stacks) effects of component tolerances and assembly process variations on the quality of manufactured products.

 

Features

  • Software tool for Design for Six Sigma initiative.
  • Quickly predict % Out of spec, DPPM, Sigma, Cpk, Mean Shift, etc. to evaluate product designs before launch.
  • Five analysis types including: Worst Case, RSS (Root Sum Squares), Modified RSS, Monte Carlo Simulations, and Process Centering RSS Analysis (account for factors like mean-shifts due to tool wear).
  • Predicts the quality of an assembly based upon predetermined build objectives (roll down studies), or determines the component tolerances to meet a given assembly build objective (roll up studies).
  • Provides Tolerance Optimizer (Patent Pending).
  • Auto-Update – change the tolerance once, and all variation analysis studies get automatically updated.
  • Graphical identification and summary feedback of all red quality issues in existing design.
  • What-if analysis Report to quickly evaluate multiple design concepts to
  • reduce costly and time-consuming extended prototyping.

Wide range of statistical distributions.

  • Single source documentation for all tolerance studies and build objectives.
  • Automatic Statistical Report generation including Sensitivity and SPC Reports.
  • Easy to use / quick to learn – Eliminates need for an expert user.
  • Perform variation analysis studies in minutes.
  • Low cost floating license pricing structure.
  • Wide range of reporting formats.
  • Single window integration.
  • GD&T syntax checker.

 

Benefits

SigmundStacks includes five methods of analysis along with the ability to create studies that can be driven either by build objective or by individual piece part tolerances. SigmundStacks even includes a powerful utility, which automatically optimizes all tolerances in a given model. These features accelerate an engineer’s understanding of the combined effects of component tolerances and assembly variation on a final assembly’s quality. Some of the key benefits associated with SigmundStacks are:

  • Greatly reduce modeling time and effort, and its succinct, reporting module provides all relevant information in four easy-to-interpret reports.
  • Easy to use menu-driven modeling capabilities reduce the user’s need to perform advanced mathematics or programming.
  • Optimizes design and assembly process, adds precision where needed, and eliminates overly costly designs.
  • Enables companies to increase product quality, reduce production costs, and get their best-in-class products to the market sooner.
  • Significant cost and time savings.
  • Reduction in Product Development cycle time.
  • Improve Quality and Reduce huge scrap, rework, retooling, recalls and warranty costs before they are incurred – High Return On Investment from use on just one program.

 

  • Root Cause Manufacturing Quality fires with built-in Sensitivity report.
  • Identify and prevent defects from occurring.
  • Identify and Select lower cost manufacturing processes in non-critical areas that will still meet all quality objectives with built-in Cost Savings reports.

Validation and Optimization of Plastic Parts

Problem Facing Plastic Manufacturer:

  • Design accuracy decisions before building multiple costly prototypes.
  • Time from concept to market, time is critical factor in the success or failure of a product.
  • Part defects discovered in manufacturing results in production delay.

How can we help:

R.C.K. Tech provides Digital prototyping and injection molding simulation services. Providing in-depth validation and optimization of plastic parts and associated injection molds, we will help you study the injection molding processes in use today. Plastic injection molding is used automotive, consumer electronics, medical, packaging industries, we well help you reduce the need for costly mold rework and physical prototypes, minimize delays associated with removing molds from production, and get your innovative products to market faster.

Plastic Flow Simulation

Simulating the filling and packing phases of the injection molding process, to better predict the flow behavior of melted plastics and achieve higher quality manufacturing. Now we can optimize gate locations, balance runner systems, evaluate processing conditions, and predict and correct part defects. Mold makers can simulate the effects of non-uniform mold temperatures, determine optimized valve-gate timing sequences, and compare flow through hot versus cold runner systems.

Early Optimization

R.C.K. Tech will guide designers, mold makers, and engineers through simulation setup and results interpretation to show how changes to wall thickness, gate location, material, geometry, mold designs, and processing conditions affect manufacturability. Geometry

support ranging from thin-walled parts to thick and solid applications helps to experiment with “what-if” scenarios before finalizing a design. This ability to evaluate different scenarios throughout the entire product development cycle results in higher quality products. We will help “get it right the first time,” to avoid the cost and time delays that frequently occur during the manufacturing phase.

Extensive Plastics Database

We use state of the art software with the largest material databases of its kind. With access to over 8,000 grades of commercial plastics with up-to-date and accurate material data, manufacturers can more easily evaluate various material candidates and have greater confidence in the simulation results, better predicting molded part properties that could affect performance.

In-Depth Simulation

In-depth simulation capabilities will help you tackle even the most difficult manufacturing problems. Providing a high degree of confidence in simulation results and support for even the most complex geometry, we will help you engineers predict and avoid potential manufacturing defects before mold tooling is created, minimizing costly overruns and production delays and accelerating time to market.

Rapid prototyping is being used in just about all industrial sectors, although there are probably more applications in the automotive industry than any other. This is not surprising, however, given the intense global competitive pressures that are being experienced by automotive firms.

Benefits of Rapid Manufacturing

  • Rapid manufacturing is used to create an item directly from the 3D CAD model of the piece, with the following benefits:
  • Increase visualization capability during the early phases of design by using rapid physical models;
  • detect design flaws before the manufacture of tooling;
  • Eliminates the creation of any tooling and tooling costs, which are usually high.
  • Low production cost overhead
  • Production speed
  • Time to market

 

3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down successive layers of material. 3D printers are generally faster, more affordable and easier to use than other additive manufacturing technologies. We give product developers the ability to print parts and assemblies made of several materials with different mechanical and physical properties in a single build process. Our Advanced 3D printing technologies yield models that can serve as product prototypes.

By uploading your 3D computer file and constructing from it a series of cross-sectional slices. Each slice is then printed one on top of the other to create the 3D object.

To upload your files you must register with us simply enter a user name and your email, a confirmation email will be sent to you with a password and a link to confirm your registration. Once you confirm your registration you go to login and go to our home page and click on upload file link on the top menu.
