Rotational Molds
There are usually a variety of classifications of molds, according to the structure of the mold, according to the use of the object of the mold, and according to the use of the mold process, and so on. In the rotomolding industry, it is generally classified according to the material used in the mold. If the mold made of steel is called iron mold, including carbon steel mold and stainless steel mold; The mold made of aluminum is called aluminum mold, including cast aluminum mold, aluminum plate mold and aluminum mold, in addition to nickel-copper alloy mold, glass steel mold, etc., of which iron mold and aluminum mold are the two most used molds in the current rolling molding industry.
What is the rotational molding process?
The rotational molding process, also known as rotomolding, is a manufacturing technique used to create hollow, seamless plastic products. It involves a four-step process: molding, heating, cooling, and ejection. First, a pre-measured amount of plastic powder is placed inside a mold, which is then closed and secured. The mold is then rotated on two axes while being heated, causing the plastic to adhere to the mold's inner surface. Once the plastic has cured, the mold is cooled, and the final product is removed. This process is known for its versatility, as it can be used to create a wide range of products, from kayaks and storage containers to furniture and playground equipment. Additionally, rotational molding is a cost-effective option for producing large, hollow parts, as it requires less labor and equipment than other manufacturing methods.
