Why injection blow molding?
When working on any project, cost is a strong consideration. But it is especially critical when working at a large scale and in industrial applications. Injection blow molding is a highly customizable process, making it easy to scale based on the customer’s needs.
At Rosti, we pride ourselves on the ability to manufacture parts efficiently, with substantial cost savings and minimal waste. While injection blow molding may not be as quick as traditional blow molding, it offers advantages in terms of the quality of the end product. This process is particularly effective for producing thicker wall parts and transparent items such as reusable drink cups. While the output volumes and speed may not be exceptionally high, the procedure ensures high-quality parts and can be run continuously for consistent manufacturing.
Advantages of Thicker Walls and Clear Finishes
At Rosti, our dedication to injection blow molding allows us to deliver reliable and adaptable solutions, pushing the boundaries of its applications beyond common expectations. This commitment to quality and innovation is what truly sets us apart.
Rosti’s innovations in injection blow molding include the ability to create products with varying thicknesses, experience with a wide range of materials and resins, and more. We have developed the mass production of glass-like, thick-walled transparent plastics for use in reusable water bottles and lighting products. By precisely controlling the blowing of partially hardened plastic, we can manufacture visually appealing products with various colors and levels of transparency.
Our injection blow molding capabilities are continually expanding and we help you take your projects to the next level.
Shifting Toward Sustainability:
A Cup for Life
As major brands move toward the concept of a “cup for life,” Rosti is here to support this change. A cup for life lets reusable cups be used for an extended period, instead of being thrown away after just one use. Rosti’s expertise in injection blow molding plays a crucial role in this transition.
A Rosti-manufactured cup for life is built to last—capable of withstanding up to 1,000 washes. Each cup comes with an RFID tag, allowing you to keep track of the number of washes. As single-use plastics legislation is being introduced worldwide, initiatives like the cup for life offer an innovative and sustainable response to meet evolving requirements.
Rosti’s expertise in injection blow molding provides a solution to support these initiatives, helping companies comply with new regulations while also delivering high-quality products to their customers.
The future requires a shift from disposable to reusable packaging, and Rosti is ready to help.
