PepsiCo has been granted a patent for a modular system that uses 3D printed molds for blow molding containers. The system includes three portions – two mold portions and a base portion – that are made of metal and can be used at different scales of production. The molds are durable and smooth enough for full production scale. GlobalData’s report on PepsiCo gives a 360-degree view of the company including its patenting strategy. Buy the report here.

A recently granted patent (Publication Number: US11759992B2) describes a modular system for blow molding containers. The system consists of three main components: a first 3D printed mold portion, a second 3D printed mold portion, and a 3D printed base mold portion. These mold portions are made of metal and can be coupled together to define a blow mold cavity.

One unique feature of this system is the use of 3D printing technology to create conformal cooling channels within the mold portions. These channels help to regulate the temperature during the blow molding process, improving efficiency and reducing cycle times.

The patent claims that each of the mold portions has a long life cycle, with a minimum of 5000 containers and potentially up to 100,000 containers. This durability is attributed to the use of metal materials and the isotropic nature of the 3D printed mold portions.

The system also includes a shell and a base shell that can be removably coupled to the mold portions. The base shell can be positioned at different heights along the shell, allowing for flexibility in the blow molding process.

In addition to the modular system, the patent also describes an interchangeable mold for blow molding containers. This mold consists of the same three 3D printed mold portions and is compatible with a blow mold system. The mold portions can be coupled to a shell to form a blow mold cavity, and the use of conformal cooling channels is again mentioned as a feature.

The patent also includes a method for making the modular blow mold system. This method involves 3D printing the mold portions, coupling them to shells and a base shell, and assembling the mold halves to form a blow mold cavity. The use of 3D printing technology and the inclusion of cooling channels are highlighted in the method.

Overall, this patent describes a modular system and method for blow molding containers using 3D printed mold portions. The use of metal materials, conformal cooling channels, and the ability to interchange mold portions and shells are key features of this innovation.
