Sheet metal forming

We offer manufacture simulation solutions like sheet metal forming, a process commonly known as stamping.

Along with experts who possess over 20 years of experience on this field, we offer analysis of each step of the forming process: blank, stamp, trim, pierce and flange.

Our capabilities are not limited just to the engineering and product development, it is also part of our professional compromise to offer recommendations along manufacturing processes that allow the production of components which meet targets and the specifications of our clients.

However, our compromise to exercise real engineering does not finish here. After manufacture feasibility analysis, we propose product re-designs at geometrical level (CAD) when materials and client’s targets are not met, by exposing it to dynamic workloads through structural CAE analysis.

Analysis Capabilities: 

- Formability Analysis of product design:

• Identification of problem zones of the part.
• Suggest modifications: geometry, material, number of drawing steps required, etc.

- Drawing analysis based on customerconcept tool:

• Process development.
• Recommendations to customer about process parameters, tooling, number of draw steps, etc.

- Tool and Pprocess development:

• Concept tool design.

• Tool design for progressive dies, transfer press and tandem process.

• Tool/Process optimization based on significant control variables:
  • Blank size/form.
  • Blank advance.
  • Forces consumption (Tons) per operation.
  • Press capabilities.
  • Tooling kinematics.

- Diagnostic Tool/ Process analysis.

- Effective guide for manufacture feasibility product development

• FLD (Forming Limit Diagram).
• Main strain diagnostic.
• Springback.
• Sheet metal thickening.
• Sheet metal thinning.
• Wrinkles prediction.
• Die marks.

We are certified expert users on the leader software for these applications: AUTOFORM©.

Injection Molding Analysis

We offer simulation solutions for plastic injection molding with capabilities for analysis, design, optimization, validation and diagnosis of the plastic injection process.

On this polymer injection molding analysis, we analyze equally the product and the process, generating recommendations for:

- Gate placement.

• Correct gate placement from the piece which can guarantee its best final quality.
• Gate location may have requirements and restrictions including part design, usage, aesthetics and tool construction.

- Molding window analysis.

• To determine how much variation may exist in mold and melting temperatures, as well as injection time.
• It can be determined which gate location gives a wider molding window.

- Gate and runner design.

• To identify the best gate and runner options for the piece.
• Runner balancing and sizing in order to optimize tool.

- Packing analysis.

• Packing is of primary importance when considering warpage, shrinkage and defects such as sink marks

- Valve gates.

• Valve gates are common for hot runner component.
• Better control of plastic flow front and packing by closing and opening of valve gates.
• Sequential gating (to eliminate weld lines).

- Cool analysis.

• To determine thermal stabilization in tool.
• Helps to determine cooling time within injection process.
• Either ideal cooling within mold or actual cooling system modeled for tool.

- Warp analysis.

• To determine how much the dimensions of a piece deviate from nominal.
• Fill + Pack + Hold + Cool + Warp analysis.
• Prediction of distortion and contraction in part.
