    • A system and method for making molded parts that include one or more planar heaters coupled, secured, or releaseably secured to one or more sides of each of the one or more nozzles. The releasably secure coupling allows heater device to be visually inspected, tested, removed, and/or replaced. The planar heater device can have a support device patterned with an electrical resistive path. The electrical resistive path can include any pitch or number of electrical resistance lines, such that a longitudinal uniform heat profile is generated along a melt flow channel of the one or more nozzles when the nozzles are in use.
    • 一种用于制造模制部件的系统和方法,其包括联接,固定或可释放地固定到所述一个或多个喷嘴中的每一个的一个或多个侧面的一个或多个平面加热器。 可释放地固定的联接件允许加热器装置被目视检查,测试,移除和/或更换。 平面加热器装置可以具有用电阻路径图案化的支撑装置。 电阻路径可以包括任何间距或数量的电阻线,使得当使用喷嘴时沿着一个或多个喷嘴的熔体流动通道产生纵向均匀的热分布。

    • An injection mold machine (10) is disclosed including a mold (40) having closely spaced mold cavities (56, 58). A heated sprue bushing (62) is disposed between the mold cavities so that the runners (142, 144) are relatively short. The sprue bushing has an elongated portion (78) that is narrow and fits between the mold cavities (56, 58). Two rather slender cartridge heaters (126) are disposed in holes (112, 114) formed in the elongated portion on opposite sides of the sprue opening (102) through which the molten material is injected.
    • 公开了一种注塑机(10),其包括具有紧密间隔的模腔(56,58)的模具(40)。 加热的浇道套管(62)设置在模腔之间,使得浇道(142,144)相对较短。 浇道衬套具有狭窄的细长部分(78),并配合在模腔(56,58)之间。 两个相当细长的筒式加热器(126)设置在形成在浇道开口(102)的相对侧上的细长部分中的孔(112,114)中,熔融材料通过浇口开口(102)注入。
