In thermoplastic processing, drying is one of the most critical yet often underestimated steps.<\/p>\n

Whether processing amorphous plastics<\/strong> \u307e\u305f\u306f semi-crystalline engineering resins<\/strong>, moisture must be reduced below the recommended moisture content before molding. Otherwise, defects such as silver streaks, bubbles, poor surface finish, dimensional instability, and reduced mechanical strength<\/strong> are inevitable.<\/p>\n

However, successful drying is not simply about heating the material.<\/p>\n

The real challenge lies in finding the optimal balance between drying temperature<\/strong> \u305d\u3057\u3066 drying time<\/strong>.<\/p>\n

This balance directly determines production quality, energy consumption, and manufacturing efficiency.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>

Understanding the Temperature-Time Relationship<\/h1>\n

Resin drying is a complex process involving both heat transfer<\/strong> \u305d\u3057\u3066 moisture diffusion<\/strong>.<\/p>\n

Its fundamental principles can be summarized as follows.<\/p>\n

Temperature Provides the Driving Force<\/h2>\n

Higher drying temperatures accelerate:<\/p>\n
