PROCESSING

Reliable Processing and Consistent Surface Quality
MagnaPBT® compounds are developed for stable and repeatable industrial processing. Because PBT is sensitive to moisture before melting, controlled drying, sealed material handling, residence time, and temperature management are essential for protecting melt quality and achieving consistent part performance.

Injection Molding
MagnaPBT® injection molding grades are available for precision components, thin-wall electrical parts, high-surface-quality components, and complex reinforced structural parts. Processing conditions are selected according to reinforcement level, component geometry, tool design, and application requirements.

Drying and Material Handling
Grade-specific drying conditions and moisture limits must be followed before processing. Proper storage, sealed transfer, and controlled residence time help protect melt quality, surface appearance, mechanical performance, and process stability.

Tooling and Temperature Control
Appropriate machine capability, wear-resistant tooling where required, controlled melt and mold temperatures, and balanced cooling support complete filling, rapid crystallization, surface quality, dimensional control, and repeatable production.

Grade-specific drying conditions, melt temperatures, mold temperatures, residence-time limits, and other processing recommendations are provided in the relevant technical documentation.
