assembler golf wood head Interview Questions and Answers

1. What materials are typically used in the construction of an assembler golf wood head?

   • Answer: Common materials include titanium alloys (for lighter weight and higher strength), stainless steel (for durability and affordability), and various carbon composite materials (for enhanced strength-to-weight ratios and adjustability).

2. Explain the process of casting a golf wood head.

   • Answer: Casting involves creating a mold (usually sand or investment casting) of the desired head shape. Molten metal is poured into the mold, allowed to cool and solidify, then the mold is broken away, revealing the rough casting.
