摘要: Method for manufacturing a gas burner of the type comprising cup, provided with at least one tubular tapered part mixer axial Venturi effect, and shaped to couple head flame-spreader, wherein said cup is made in single piece by casting or die-casting an apposite mould. Such method comprises, sequence, following steps: a) arranging mould two shells, afore cup; b) core which could be removably inserted into respective mould, has jutting portion strickle effect; c) inserting such closing shells so that retained, partially, distance from opposite inner walls closed mould; being ending replaces, perimetrical area defined d) pouring pressure-injecting molten metal material e) opening drawing out then removing die formed after solidified; f) applying plug side hole (or holes) corresponds/ correspond replaced
