- High energy consumption during the heating and forming stages
- Use of virgin plastics contributing to fossil fuel depletion
- Production waste and off-spec products
- Challenges in recycling multi-layer or opaque bottles
Recognizing these issues, Leshan has pioneered a shift toward sustainable blow molding practices that prioritize resource conservation, circularity, and reduced environmental footprint.
Leshan’s Commitment to Sustainable Manufacturing
Eco-Conscious Machine Design
Leshan’s engineering philosophy focuses on creating blow molding machines that minimize energy use and material waste. Key design aspects include:
