GREG STOUT | Rotational Molding Design, Injection, Blow Molding & Thermoforming Plastic Design


Plastic product design, whether it be for rotational molding (aka rotomolding), blow molding, thermoforming or injection molding has a series of process guidelines that must be adhered to in order to achieve a successful plastic part. Greg Stout is an experienced plastic product designer who can guide you through the specific requirements of each process in addition to designing a great looking plastic product.
Greg provides product design services for all plastic processes including:

    • Rotational Molding Design
    • Blow Molding Design
    • Thermoforming / Vacuum Forming Design
    • Injection Molding Design

In addition to product design, Greg works with clients to help find rotational molders, mold/tooling manufacturers, materials specification and FEA (finite element analysis) to ensure that they final design meets all the performance requirements.  

Rotational molding design is a specialized field that has a unique set of rules and guidelines to ensure that a product can be successfully rotationally molded and achieve all the required
specifications. It not only takes experience with the rotational molding process, knowledge of the rotational molding companies who will be manufacturing the product, but also materials, tooling, material flow in addition to a strong plastics engineering background to successfully design rotomolded products. This is a small industry compared to blow or injection molding so specialists experienced in rotomolding design are limited to one or two individuals across the United States.

Greg Stout is a seasoned designer in the field of rotational molding and a specialist in the design of hollow plastic products for the following processes; rotational molding, blow molding and thermoforming. With over (25) years experience in the rotational molding process, Blue-Reed not only provides innovative and creative product design, but also coordination with the rotomolder and mold maker to reduce part and tooling costs.

If you are looking for further information on what is rotational molding, rotational molding design guidelines, rotational molding companies / roto molders, or a roto mold manufacturer, we can help you locate the right supplier. We have a vast network of rotational molding companies with whom we work, rotomold makers and machinery manufacturers.

Rotational molding is a plastics process to produce both simple and complex hollow plastic parts. It’s a great process for low-volume parts  since the molds/tooling are relatively inexpensive compared to injection or blow-molding tooling.  Rotational molding is a process lends itself to low volume production and part quantities of 2,000 or under per year.  It is also an excellent method to produce very large hollow plastic parts.  Typical examples large parts include boats, kayaks, septic tanks, large holding tanks, trash dumpsters/lids and playground equipment. Another reason designers choose rotational molding is due to highly complex geometric shapes, deep draws and zero draft that can be incorporated into each part such as a 360 degree spiral slide found on a playground. No other hollow parts process has the design freedoms and potential of rotational molding.


A key to our success and the success of the products we design is the relationships we have with rotational molding companies throughout North America. We possess an intimate knowledge of their equipment, capabilities and competencies. We would be more than happy to assist you in locating a molder that fits both your geographical and part complexity requirements. We even have relationships with molders as far away as China.
