Rotational Molded and Prototype Parts

Rotational molded parts, ProtoEdge can be of help to you in many different ways. We work with you when your CAD designs includes, inserts, different kinds of materials, multi-layered walls, unusual shapes, assembly, light weight models, and structural integrity.

Rotational molding is also referred to as rotocast or rotomolding, is a thermoplastic method for making hollow parts. And by placing powder or liquid resin into the hollow mold and is rotated by that tool bi-axial in an oven until the material melts and coats the inside of the mold cavity.

The rotomolding process can assist with the following:

  • Design flexibility allowing complex geometry
  • Stress free parts
  • A Few Inches to Over 20 Feet
  • Potential weight reduction
  • Short Lead-times
  • Metal Inserts
  • Parts offer strength, corrosion resistance and durability

The prototype mold part is cooled then part is removed from the mold. Producing parts out of polyethylene have a vast range of materials that can be used in the rotational molding process. They include linear low-density polyethylene (LLDPE), cross-linked polyethylene (PEX), low-density polyethylene (LDPE), and high-density polyethylene (HDPE).

Adjustments also can be made for density, texture, color, and within the same batch run. The rotational method is an ideal way to produce large, light weight, one-piece parts. This molding process offers great flexibility for both in product design and low-volume parts production.

Custom rotational molding when compared to other methods, like injection molding and blow molding, it is important for you to choose the correct rotational mold process for your application. Since each type of mold lends itself to various types of polymers when making durable products.
