Background technology
Iron-type golf club head is typically divided into " knife back formula " and " perimeter weighting formula ".
The quality of perimeter weighting formula iron-type golf club head is the most intensively distributed in after striking surface,
The form taked is the perimeter weighting part of at least one periphery wall body-also commonly known as.Periphery adds
The iron-type golf club head of weight is alternatively referred to as " hollow type " iron club head, or directly claims
For " hollow type " because perimeter weighting part generally limit on glof club head with batting
Cavity scope in the back of face opposite side.
One of important performance of hollow type iron is that impact passes to player's
Sense of touch is fed back.For reducing the bad dynamic exciting of mistakenly hit moment generation, the week of hollow type club head
A supplementary dampening assembly can be increased in the weighted item of limit.In order to make described dampening assembly with club head
Between couple firmly, need to fix the structural integrity of dampening assembly to club head by being used for.Institute
The weight stating fixed mechanism will increase the gross weight of glof club head, thus weakens club head
Performance.Additionally, the shape of described fixed structure is not so simple on surface, certainly will will increase
Add the difficulty of whole processing technology, thus improve production cost.
