High Stability Aluminum Rotational Molds Consistent Wall Thickness
Advantages
- Low-cost tooling: low operating pressures allow rotomold tooling to be crafted from low-cost metals such as aluminum
- Consistent wall thickness: the constant rotation of the mold coats the walls evenly during both the heating and cooling processes
- Double-wall construction: complex double-walled open containers can be produced without secondary processing
- High durability: parts are molded as one solid piece, eliminating the need for joining techniques such as welding and joint fabrication which creates weak spots
- High stability: the molding material isn’t exposed to external pressure, increasing its stability and reducing the risk of defects in the finished part
- High strength: rotomolding creates thicker corners, reducing the risk of failure in these stress-concentration points
- Appearance: the soft metal used for the rotomold tooling easily accommodates surface finishes such as fine-detail textures, logos, symbols, and lettering
