Metering FeedersSpectra System
A variable -speed, D.C. motor powers a selected metering auger that volumetrically feeds colorants or additives upon a signal from either the injection or blow molding machine cycle, or in conjunction with extruder speed.
Shipped ready-to-runVariety of mounting possibilities. A colorant/additive supply bin is provided which can be automatically loaded or hand filled. The bin and metering auger mount on a special throat adapter. The bin can be removed easily for cleaning. The Spectra’s throat adapter mounts between the material hopper and the machine throat. Two Spectra’s can feed through one adapter. By simply bolting two throat adapters together, multiple metering units can be mounted on one machine. This arrangement provides for different additives to be fed at one time, or provides nearly instant color changes on a single machine without shut down for cleaning.
Fast, easy auger and color changes.
Spectra’s supply hopper is quickly emptied through a clean out door for material changes. When the door is opened, the metering auger is disengaged as a safety precaution. A similar door is provided under the discharge end of the auger for sampling calibration. A safety grill is provided in the metering port.
