Plastic Flower Pots Tall Planters Products Made By Rotational Moulding

Why rotomolding?

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.
5. Rotational molding allows for the integration of multiple parts into one piece, saving on manufacturing and assembly costs.

The principle of rotational molding of plastics is simple. Basically the process consists of introducing a known amount of plastic in powder, granular, or viscous liquid form into a hollow, shell-like mold.The mold is rotated and/ or rocked about two principal axes at relatively low speeds as it is heated so that the plastic enclosed in the mold adheres to, and forms a monolithic layer against, the mold surface. The mold rotation continues during the cooling phase so that the plastic retains its desired shape as it solidifies. When the plastic is sufficiently rigid, the cooling and mold rotation is stopped to allow the removal of the plastic product from the mold. At this stage, the cyclic process may be repeated. The basic steps of (a) mold charging, (b) mold heating, (c) mold cooling, and (d) part ejection.
