Processing and forming methods for plastic rolling

Rotational molding, also known as rotational molding, rotational molding, rotational molding, etc., is a technological method used to hollow form thermoplastic materials. Plastic products can be made in a variety of shapes, sizes, and colors (inside and outside). The product features integrated molding and can be manufactured with three layers of foam as needed to enhance the strength of the barrel. The product is lightweight, tough, highly impact resistant, and has good chemical resistance, making it a rare plastic processing and molding method.

Blow Molding Process for Transparent Plastics

Due to its high light transmittance, the transparent plastic should have strict requirements on the appearance quality of plastic products, which should not have any spots, air holes or whitening. Halos, black spots, discoloration and poor gloss are drawbacks that affect the quality of materials and equipment throughout the blow molding process. The planning of the molds and even the products need to be given high priority. Secondly, due to the high melting point and poor activity of transparent plastics, in order to ensure the appearance quality of the product, it is often necessary to fine-tune the technical parameters of the machine temperature, injection pressure, injection speed, etc. Therefore, the injection of plastics not only fills the molds, but also prevents internal stresses from causing deformation and cracking of the product. Therefore, it is necessary to carry out strict operations in material preparation, equipment and mold requirements, injection technology, and material treatment of goods.
