ABS VS PC in plastic injection molding
Pros and Cons of ABS as plastic injection molding material
Pro tips: design for plastic injection molding
Embrace Uniformity
Wall thickness consistency is crucial.
Uneven thickness can lead to warping, sinking, and weak spots. Aim for consistent wall thicknesses between 1.2mm and 3mm, depending on the chosen material. Avoid sharp transitions and sudden changes in thickness.
Draft It Right
Draft angles are essential for easy part ejection from the mold.
Aim for 1° of draft per inch of part depth, but adjust based on material, texture, and complexity. Remember, zero-draft areas can be tricky, so minimize them where possible
Radius are Your Friends
Sharp corners and edges act as stress concentrators, potentially leading to cracks and fractures.
ncorporate smooth radii at transitions and intersections. Aim for radii at least equal to the wall thickness for a balanced design.
Embrace Ribs and Bosses
Ribs and bosses add strength and rigidity.
However, design them strategically. Keep rib depths less than half the wall thickness and ensure smooth transitions to avoid stress points. Bosses should be positioned away from ribs and have adequate draft angles for easy ejection.
Mind the Undercuts
Undercuts often defines the complexity of the mold.
Undercuts, features that require the mold to pull apart in directions other than the split line, can significantly increase mold complexity and cost. If possible, redesign to eliminate undercuts or consider alternative manufacturing methods.
Think About Finishing
Consider how the final part will be finished (e.g., painting, plating).
Ensure design features like text or logos are raised or recessed appropriately for proper finishing techniques.
Material Matters
Different materials have unique properties and limitations.
Choose a material that aligns with your application's functional requirements, considering factors like strength, heat resistance, and chemical compatibility. Consult with material experts for optimal selection.
Prototype Before Production
Prototyping allows you to test your design for functionality, manufacturability, and potential issues
This can save time and money by identifying and addressing problems before full-scale production begins.
Collaboration is Key
Partnering with experienced injection molding companies like coremould early in the design process is invaluable.
Their expertise can help refine your design for optimal manufacturability, reducing costs and ensuring success.
Stay Informed
The world of plastic injection molding is constantly evolving.
Stay updated on new technologies, materials, and design trends to ensure your products remain competitive and innovative.
Simulate the results
Lots of softwares to allow you to see before you make.
Utilize software specifically designed for injection molding design, such as Moldflow or Autodesk Moldflow. These tools can help you simulate the molding process, identify potential issues, and optimize your design for success.
