LLDPE Plastic ManholeRotational Moulding Products By Aluminum A356 Rotational Molds

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.

1. Rotational molding, including capital equipment (machinery, processing equipment, etc.) is a cost effective option for plastic manufacturing.
2. Rotationally molded parts are 100% stress-free, have excellent impact resistance, and can withstand chemical and environmental attack.
3. Value added features, such as threaded tank necks, inserts, double walls, intricate contours, etc. can be produced via rotomolding.
4. Speed-to-market advantage: once a design is finalized, tooling can be produced in a manner of weeks, offering a distinct advantage over other processes.
