About OSLON

Focused on precision packaging mold projects.

Engineering, manufacturing coordination and direct international project communication from Taizhou, Zhejiang.

Company profile

Built around project clarity.

OSLON Precision Mold was founded in 2008 and completed its brand upgrade in 2018. The company focuses on PET preform molds, cap molds, hot runner systems and customized packaging tooling.

Our international workflow separates confirmed requirements from fields that still need engineering review. That makes quotations, project communication and published case material easier to audit.
