An existing customer invited Optimas to explore a cost saving initiative relating to an electrical control box in a commercial air conditioning unit. Prior innovation failed to develop a fastening solution which would yield cost savings.
The original design of the control box enclosure contains a large steel stamping along with an outer casing that is installed on the face of the cabinet. This acts as a sealed unit to prevent leaks and moisture.
The internal plate is designed and manufactured with a large range of pre-pierced holes to house every potential electrical component configuration. On average, the customer only used 30% of the holes built into the electrical control box.
A cost–and labor–savings initiative that eliminated an under–used part of an electrical control box in a commercial air conditioning unit.
Design a “dimple” style fastening system, including a range of sharp-crested, thread–forming screws, that engages on contact with walls and:
- Adheres to UL production requirements
- Eases the mounting process during manufacturing
- Allows for “change outs” in the field
- Ensures a watertight seal
