Part Design Guidelines

The “Injection Molded Part Design Guidelines” will review items to consider when designing your next plastic component like:

  • Maintaining uniform wall thickness to minimize sinking, warping and improve mold fill.
  • Using generous radius at all corners to avoid sharp corners that increase stress concentration which can lead to part failure.
  • Incorporating sufficient draft angles for easy removal of the part from the mold.
  • Using ribs or gussets to improve part stiffness.

Mold Design Guidelines

Crescent Industries’ mold design engineers look at the aspects of the part that are important for injection molding.  Through adherence to these design principles and best practices at the beginning of the design process will ultimately lead to better overall quality of parts during manufacturing. These “Mold Design Guidelines” will evaluate items like the follow:

  • Gate Designs / Runner Designs
  • Cooling / Venting
  • Actions
  • Mold Filling

  • Is it time for a new Medical Injection Molding supplier? Here’s some tips.
    There are endless reasons as to why an OEM will choose to change their medial injection molding supplier or think to change. The main 6 categories that we often see as the culprit are:
  • Obtaining an accurate proposal for injection molded tooling and components
    The Request for Quote (RFQ) and competitive bidding process is an important one for the plastic injection molding industry. Not only does it help OEMs secure the best overall value and quality results for their production needs, but it also rewards high-performing contract manufacturers with business, providing competitive pressure for the innovation, specialization, and continuous […]
  • How to Evaluate Total Cost of Ownership
    One of the biggest issues in the injection molding industry—for both molders and customers—is evaluating the total cost of ownership of a product or project. Though there are several things OEMs can do to make their RFQ’s more accurately match their molding needs, customers still need to carefully and comprehensively analyze the quotes received from […]
