Identifying Common Automotive Thermoplastics
Identifying Common Automotive Thermoplastics
Most plastics used in vehicles today are thermoplastics, meaning they can be melted; therefore, they can be fusion welded with a nitrogen plastic welder. While there are many types of... Read more...
Why Is Adjustable Flow Important?
Why Is Adjustable Flow Important?
All of Polyvance's nitrogen plastic welders feature adjustable flow control, allowing users to tailor the flow to suit the plastic being welded. The recommended baseline flow is 12 to 13... Read more...
