共栄化成 Company Overview

Stable procurement unaffected by crude oil conditions. Reducing raw material costs by 40-50% and supporting the replacement of plastic products with high-quality recycled materials derived from used PET bottles.

Our injection molding service utilizes recycled PET (rPET), which is one of our strengths. Amid ongoing unstable geopolitical risks, we achieve both environmental considerations and dramatic cost reductions through a stable procurement route that is not affected by crude oil prices. ■ Transition to recycled PET as a risk management strategy The recent instability in crude oil has led to soaring prices and supply uncertainties for virgin materials. On the other hand, our recycled PET is made from PET bottles collected from municipalities in Japan, so it is completely unaffected by fluctuations in crude oil prices. We have established a stable supply system necessary for mass production through continuous transactions with domestic recycling companies. ■ Stable quality control and cost advantages We address issues such as hydrolysis and release defects through strict drying management and optimization of mold design. By considering the flow characteristics for each lot and fine-tuning the injection conditions accordingly, we prevent defects like burrs and shorts, enabling stable molding in various colors such as transparent and white. In some cases, raw material costs have been reduced by approximately 40-50% compared to virgin materials. *For more details, please download our catalog or feel free to contact us.
