The decision to use plastic instead of metal seems like a no brainer given the many advantages like lighter weight, lower material costs, quicker manufacturing times and extended tooling life.

However, metal to plastic conversion is more than just a matter of material substitution. Beyond differences in materials composition and behaviors, there is often opportunity to re-create a multi-component metal part into a unibody plastic piece. This introduces a number of intricacies that allow for greater design freedom and optimum manufacturability. As such, the conversion is best undertaken by anexperienced complex injection molder with engineers skilled and proven in Design for Manufacturability (DfM).

A Comprehensive Approach

DfM methodically steps through each phase of metal-to-plastic conversion projects, drilling down into:

  • Motivation: What’s driving the change in part fabrication, and what are the anticipated results?
  • Application: How will the part be used? Are the materials appropriate for the anticipated stresses and environment?
  • Cost-benefit analysis: Do plastic components profitably offset metal fabrication costs in tooling, materials, scrap reduction, product runs, automation, secondary operations and product life?
  • Design: Not all metal parts neatly translate to plastic. Can the design be adjusted to compensate without jeopardizing performance? An OEM and injection molder must collaborate to appropriately optimize part design using a DfM study.

Better Outcomes

By understanding and addressing all key considerations at the project outset, DfM ensures the molding process and metal to plastic conversion solution is viable and valuable for the OEM. The DfM process:

  • 保证所有新材料选择可以处理the load, temperature fluctuations and other environmental conditions
  • Determines if a plastic part will hold injection molding tolerances under required stresses and pressurization
  • Identifies potential compatibility issues, either between materials used on the part, or between materials and substances the part will encounter
  • Maximizes part performance over time

Taken in total,the project-specific answers DfMprovides optimizes the metal to plastic conversion process that, in turn, is critical to achieving desired and profitable results.
