Quality Control

                           QC STAFF KEEPING TRACK OF EACH STEP
Step1
Plastic raw material (typically in powder form) is placed inside a mold (cast aluminum, CNC machined aluminum)
Step2
The mold is attached to an arm of a rotational molding machine, and enters the oven where it rotates (rotational molding) on two axes.
Step3
As the plastic material melts, it begins to adhere to the inside mold walls, building wall thickness and taking on the shape and texture of the interior mold surface.
Step4
After rotating in the oven, the mold enters the cooling phase, where the molten material eventually solidifies into the finished, hollow plastic part.
Step5
The part is then removed from the mold, where it undergoes a variety of secondary operations (trimming, foam-filling, assembly, etc.) prior to shipment.
