HASCO Plastic Injection
Problem:
HASCO®, an international mold manufacturer, was charged with creating plastic injection molding equipment for the manufacture of pharmaceutical spray bottle screw caps. The system design required:
- High dimensional stability of finished apart: 0.05mm for threads, sealing edges, and snap-in edges
- Suitability for clean room production
- Cycle time less than 17 seconds
- Effective demolding – part has undercuts, angled ribs, and threads
Design:
HASCO® engineers created an innovative solution and incorporated standard transmission components and prehardened, tempered stainless-steel molds. Dicronite® was applied on the molds and all transmission components including gear wheels, toothed racks, ball bearings, spherical bushings, guide rails, and guide blocks.
Results:
- Dimensional stability was maintained.
- Faster mold movements resulted in shorter cycle times.
- Friction and heat was reduced, resulting in less wear of transmission components.
- No additional lubrication was necessary and therefore, no particulates or outgassing compromised clean room environments.
- Dicronite® bonded to mold surfaces as well as guide rails treated with a hard coating.
Molds released effectively in extremely high temperatures.
With the help of Dicronite®, HASCO® delivered an effective clean room manufacturing solution capable of producing plastic parts for pharmaceutical use.
