About Propprose: The Engineering Plastics & Molding Diagnostics Database

Propprose is an independent, data-driven technical library designed for manufacturing engineers, injection molding technicians, and B2B procurement specialists. We simplify complex industrial processes by organizing disparate standards, polymer properties, and machine alarm codes into a zero-latency, highly structured database.

Our mission is to reduce downtime and streamline material sourcing in precision manufacturing. We cover two deeply interconnected B2B niches: high-performance polymers (PEEK, Ultem, PTFE, PPS, LCP, polyimide) and precision injection molding machine diagnostics (Netstal, Arburg, Engel alarm codes and troubleshooting).
