Plastic enclosure manufacturers can use rotational molding or injection molding to produce the housings that protect and surround electrical and mechanical systems. Both plastics manufacturing processes can use materials such as polyethylene (PE), polypropylene (PP), linear low-density (LLDPE), or high-density (HDPE). For electrical and electronic applications, static-dissipative PE may be used instead.
Rotational molding uses lower-cost tooling, however, and rotomolding – as it’s also known – can support the creation of shapes and features that are impossible to achieve with other manufacturing methods. Plus, rotational molding supports strong, hollow products in a range of sizes. If you’re a product designer who’s comparing plastic enclosure manufacturers, don’t limit your search to injection molders. Instead, consider how Gregstrom, a Made in USA rotational molder, produced these plastic housings.
3D Printer Housings
This 3D printer housing demonstrates how rotational molding can produce strong, durable and functional enclosures for additive manufacturing equipment. Rotomolding can create plastic enclosures like this in a wide variety of shapes, sizes, textures, and colors with features such as undercuts, multiple walls, and molded-in hardware. In addition to rotational molding services, Gregstrom provides product assembly and can even manage your finished goods inventory.
Lawn and Garden Equipment Housings
Gregstrom can also produce rotomolded products such as this lawn and garden equipment housing. We readily offer design assistance and can help you with material selection so that the enclosure material you choose provides strong environmental resistance against rain, sunlight, and outdoor temperatures. As a value-added rotomolder, Gregstrom also offers plastic finishing services with CNC and robotic routing. These processes trim rotomolded parts to their final dimensions and support efficient assembly.
