Abstract
In production of a golf club head by heat pressing of a compound in a splittable mould, the compound of a fixed weight is injected into the mould cavity through an injection tube which is clamped by the mould and removed after appreciable hardening of the compound. Provision of an asylum for extra bulk of compound by the injection tube remarkably reduces production of undesirable dregs or flash at heat pressing. The injection tube also serves to define the correct positioning of a core used in the product.
