FAQ:
1). What is involved in injection mold preventive maintenance?
All molds have moving pins in them to eject the part out. Maintenance will include periodic greasing of these pins, as well as all other moving components, and cleaning of the cavity and core surfaces. Best of all, we provide lifetime maintenance at no additional cost on all of our customer molds!

2). What is the difference between a multi-cavity mold and a family mold?
A multi-cavity mold has multiple cavities of the same part; a family mold produces a set. For instance, for an electronic enclosure, you may need a front, back, battery door, and a button. Those could all be molded at once in a family mold.
What is the data required for quoting an injection mold?
