Abstract: In July 2018, I faced a significant challenge in the plastic injection molding industry while working in North Carolina, USA. Parts molded using Optipro glass-reinforced polypropylene (PP) were scrapped due to warpage and rigidity issues, which risked causing significant financial losses and delayed shipments to customers. Rather than scrapping the parts, I developed a unique recovery process that involved reheating the parts in an infrared oven at 230°F, followed by a controlled cooling method to regain flexibility and prevent warpage. Over time, I implemented a fixture-based cooling system, which improved efficiency, eliminated defects, and ensured zero customer complaints. This paper discusses the development of this recovery process, its implementation, and the substantial cost and time savings achieved. It also provides insights into how this process can be applied to other thermoplastic materials in the injection molding industry.

Keywords: recovery process, plastic injection molding, glass-reinforced polypropylene, infrared heating, warpage prevention, controlled cooling, thermoplastic materials, cost savings, sustainability, Optipro PP.
