One Partner for Sealing materials, Seals and CNC seal manufacturing technology

Pulim is a sealing technology manufacturer built around three core capabilities: Material Development, Integrated Manufacturing, and Production Systems. We develop our own polymer materials, manufacture molded and machined seals, and design CNC seal machining systems with proprietary software. By aligning material development, seal production, and machining technology under one structure, we reduce performance risk, shorten development cycles, and ensure consistent supply across projects.

Material Development

In-house polymer formulation and semi-finished materials engineered for performance and durability.

Multi-Process Manufacturing

Injection molding and CNC machining for both standard and custom sealing production.+compression molding,rubber injection.

Integrated Manufacturing,and Production Systems

Seal manufacturing system and proprietary software for precision, repeatable seal manufacturing.
