Gravimetric Feeder an ‘Industry First’ for Micro-Molding Sector

Ampacet ColorSave Micro gravimetric feeder
The ColorSave-Micro from Ampacet uses a single, vibratory, protected inner channel to eliminate exterior vibration and consistently deliver accurate doses with let-down ratios as low as 0.1%.

Designed for plastics processors in the growing micro-molding market, a gravimetric feeder described as an “industry first” by Ampacet enables accurate dosing down to the pellet level for medical, automotive, and electronics applications.

The patented ColorSave-Micro uses a single, vibratory, protected inner channel to eliminate exterior vibration and consistently deliver an accurate dose. ColorSave-Micro can accurately dispense materials with let-down ratios (LDRs) as low as 0.1% to 0.3% for small-part production or to reduce material costs for extruded parts. Gravimetric weighing ensures consistent accuracy when compared with volumetric micro feeders.  

A fast-growing industry segment, the micro-molding market is expected to reach more than $1.5 billion by 2025, with North America projected to occupy the largest share at nearly 40%, according to Grandview Research.

The ColorSave-Micro can be used for nearly all types of additives, including flowable, non-dusty powders or granules, and micro pellets, said Ampacet, a masterbatch supplier operating 25 manufacturing sites in 18 countries. The system handles low feed rates and can be easily cleaned between jobs, added the company.

“The ColorSave-Micro boosts productivity dramatically. It eliminates manual mixing, makes calibration easy, and turns product rejects into a thing of the past,” said Doug Brownfield, Commercial Director of Ampacet business unit CISystems. “Our customers love that they can use expensive colors and additives at the lowest possible LDR, enabling them to run at the low end of the tolerance specification to save on masterbatch costs.”  

Part of the LIAD Smart family of feeders, ColorSave-Micro can be used in injection molding, extrusion, and extrusion blow molding processes and is well-suited for research, testing and prototyping facilities.

CISystems recently acquired LIAD Weighing and Control Systems, specialized in plastics manufacturing technologies and the development of feeders, blenders, and quality control equipment.
