摘要： Injection molded ring fan embodiments and methods for making them. The methods influence material flow during the injection molding process such that a major portion of the materials flowing in opposite directions in the outer rings preferably flow past one another, intermix in a swirling relationship, and/or collide at an angle relative to one another. This results in better material mixing or integration of the flow fronts. In one embodiment, the thickness of the outer ring varies in different portions between adjacent fan blades.

摘要： A method to influence material flow during the injection molding of thermoplastic, polymeric ring type fans such that a major portion of the materials flowing in opposite directions preferably flow past one another, or collide at an angle relative to one another, rather than colliding at an 180 degree angle relative to each other to form weld lines. This flow bypassing results in better material mixing or integrating than merely allowing flow fronts to collide and cool. In one embodiment, a portion of the fan's ring is thickened in the weld line area to minimize the amount of material colliding at a 180-degree angle relative to each. Alternatively, at least one appendage could be added to the ring fan that will influence the material flow during molding conditions. Each appendage will be removed prior to introducing the ring fan to a cooling system.
摘要翻译：一种在热塑性聚合环型风扇注射成型期间影响材料流动的方法，使得沿相反方向流动的材料的主要部分优选地彼此流动或相对于彼此以一定角度相撞，而不是在相对于180度角形成焊接线。这种流量旁路导致更好的材料混合或集成，而不仅仅是允许流动的前沿碰撞和冷却。在一个实施例中，风扇环的一部分在焊接区域中增厚，以使材料的量相对于每个角度以180度的角度相撞。或者，可以在环形风扇中添加至少一个附件，这将在成型条件期间影响材料流动。在将环形风扇引入冷却系统之前，每个附件将被删除。
