For most products, tooling is expensive and requires considerable lead time. Simulating its performance before cutting steel saves considerable time and expenditures that otherwise fall under adjustments.
Finite Element Analysis or FEA is a numerical technology that when applied to developing a rubber or plastic product allows to virtually simulate its performance prior to tooling and testing.
Every car scraps a tire a year on average. Strategies to cater to such a huge and growing waste stream consisting of incineration, crumb rubber generation, and landfilling, are not effective.
There are differences between design for cost and design to cost. Design for cost consists of optimizing a product for the least amount of material, highest performance, and recycling after usage.
Injection molding is the fastest process to make polymeric products. The material is continuously fed as pellets or rolls into an extruding barrel before feeding single or multi-cavity molds.
Trial-and-error presents many disadvantages. The alternative is material characterization and product simulations based on Finite Element Analysis and Computational Fluid Dynamics (FEA and CFD).
No company can do everything alone. The alternative is out-sourcing. This encompasses material developments and supplies, research and development, testing, and many non-core activities.
