Plastic Rotational Moulding Scrubber Shell , Die Casting Molds Plastic Products

1. About Rotational Moulding:

Rotational moulding, known also as rotomolding or rotocasting, is a process for manufacturing hollow plastic products. For certain types of liquid vinyls, the term slush molding is also used. Rotational molding has particular advantages in terms of relatively low levels of residual stresses and inexpensive molds. Rotational molding also has few competitors for the production of large (> 2 m3) hollow objects in one piece. Rotational molding is best known for the manufacture of tanks but it can also be used to make complex medical products, toys, leisure craft, and highly aesthetic point-of-sale products.
2.The process begins with specially developed and uniquely applied resins. They can include plastisols, polyethylene, polycarbonate, acetate butyrate, polyamide, elastomers, polyurethane, polypropylene, ethylene vinyl acetate and fluorocarbons. Some of the most advanced work is being done with cross-linked polyethylene and even nylon.
3.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.

Shanghai Jiechuang Mold Manufacturing Co.,Ltd. is located in the Songjiang District of Shanghai city which is so historical that it was named “the Root of Shanghai”. With only 30-minute distance from Hongqiao Airport, the traffic here is very convenient. Set up in 2015, Jiechuang now possesses 1 million registered fund and more than 5 million actual investment. Its team and major engineers all have worked in rotational moulding industry for more than 10 years, which makes Jiechuang a modern economic entity that concentrates on technological research, design development ,manufacturing, trade and investment.
