Fluorine Mixtures

Virtually all plastic surfaces can be treated with fluorine and nitrogen mixtures -- from hollow bodies and shaped parts to fibers, composites, films and foams. Advantages of fluorination surface treatment compared to common pre-treatment methods include easier process control that can be reproduced, longer lasting preliminary treatment and reduced solvent and chemical permeation.

Nitrogen

Nitrogen can be used as a cooling and blowing agent in blow molding applications. Replacing air with nitrogen can help you reduce cycle time per mold, resulting in a more efficient heat transfer compared to air cooling. Plus it can allow you to eliminate the need for compressed air, improve dimensional stability of the molded parts and enhance weld strength. It is especially suitable for thick walled parts with long cycle time. Liquid nitrogen can help you increase productivity without sacrificing product performance of dimensional quality.

Equipment

Deflashing Systems

Our systems use liquid nitrogen as a refrigerant, for lower costs, shorter cycle times and improved part quality. Our deflashing specialists can help you design, install and support a system to meet your needs, whether you simply need cooling or a full system.
