Roto molding is also called rotational molding. The OEM roto moulding method is to first add the metered plastic into the mold, and after the mold is closed, make it rotate along two vertical rotation axes, and at the same time make the OEM roto moulding When the mold is heated, the plastic raw materials in the mold are gradually uniformly coated and melted and adhered to the entire surface of the cavity under the action of gravity and thermal energy. OEM roto moulding is formed into the same shape as the cavity and then cooled and shaped. During the entire molding process of OEM roto moulding, the plastic is hardly affected by any external force except for gravity. It is a hollow molding method for thermoplastics. OEM roto moulding has its characteristics, so what are the characteristics of OEM roto moulding? It is divided into two aspects, one is in the formability of OEM roto moulding, and the other is in the molding process of OEM roto moulding. Let us take a look.
This is the content list:
l In terms of the formability of OEM roto moulding
l In the molding process of OEM roto moulding
OEM roto moulding products have a uniform wall thickness, no corner scraps, and no welds. OEM roto moulding can form products with a wide range of wall thickness, such as polyethylene rotary forming parts, the wall thickness can be in the range of 1~16mm. However, due to the viscosity of OEM roto moulding, it is difficult to form thick-walled products. The rotational molding process is particularly suitable for molding 2~5mm plastic products. OEM roto moulding usually can only produce hollow products or sell products, it is difficult to process solid products, and the surface condition of OEM roto moulding products is highly dependent on the surface of the mold cavity. The dimensional accuracy of OEM roto moulding products is low, and its dimensional accuracy is usually ±5%.
OEM roto moulding is suitable for molding large and extra-large parts. Because OEM roto moulding only requires the strength of the frame to support the weight of the material, the mold and the frame itself, and the closing force to prevent material leakage, even if OEM roto moulding processes large and super large plastic parts, it does not need to use very bulky Equipment and molds. Therefore, theoretically speaking, products made with OEM roto moulding have almost no upper limit in size. OEM roto moulding is suitable for the production of multi-variety, small batches of plastic products-due to the simple structure and low price of the molds used for rotational molding, it is very convenient to change products. OEM roto moulding is suitable for processing large hollow products with complex shapes, which is unmatched by other molding processes. The color of OEM roto moulding plastic products is easy to change. When the color of the product needs to be changed, only the molding mold needs to be cleaned.
