Prototype Rotational Molding

Prototype Rotational Molding consists of a heated hollow mold which is filled with a shot weight or charge of material. The mold is then slowly rotated and in order to maintain an even level of thickness, the mold rotates at all times during the heating process.

Having the ability to create hollow prototypes through prototype rotational molding is essential for certain products such as, tanks, bottles, tubes and more. Here at Met-L-Flo, Inc. we answer your need for hollow products with rotational, blow molding and casting prototypes.

The Benefits of Prototype Rotational Molding

The unique process of prototype rotational molding allows for a variety of applications and geometries including over molding inserts. At Met-L-Flo, we have extensive experience with hollow castings and they have a tight tolerance.

Some of the benefits and advantages of rotational molding include the following:

  • Quick Tool Production
  • Customized Durometers
  • Consistent Exterior Surface Finish
  • Customized Color Matching
  • 20 to 40 Parts Per Tool

Our experienced staff can help get your parts cast and molded to your specifications, efficiently and with the best quality. Integrating 3D printing technology into prototype rotational molding has increased precision to new heights. One of the biggest advantages of prototype rotational molding is that it can create a functional prototype that can hold materials, allowing you to test your prototypes performance before you begin production.
