Frequently Asked Questions (FAQ)

Q1. What are brass inserts for plastics used for?

Brass inserts are used to create strong, reusable internal threads in plastic parts, allowing repeated assembly and disassembly without damaging the plastic.

Q2. Which insertion methods are suitable for brass inserts?

Brass inserts can be installed using heat-staking, ultrasonic insertion, molding-in, or press-fit methods depending on the plastic material and application.

Q3. Why are brass inserts preferred over steel inserts?

Brass inserts offer better corrosion resistance, smoother threading, non-magnetic properties, and compatibility with plastic materials, reducing the risk of cracking.
