Plastic barrel manufacturers tell us how plastics are processed into plastic barrel molding equipment. Processed thermoset plastics are typically molded, transfer molded, and injection molded. Lamination, molding, and thermoforming are the shaping of plastic on a flat surface. Plastic processing methods can be used for rubber processing. In addition, there are castings using liquid monomers or polymers as raw materials. Among these methods, extrusion and injection molding are used most and are the most basic molding methods. Bonding of plastic processing Plastic processing involves joining together plastic parts by soldering and bonding. The welding method is hot air welding using electrodes, hot melt welding using hot poles, and high frequency welding, friction welding, induction welding, ultrasonic welding, and the like. The bonding method can be divided into a flux, a resin solution and a hot melt adhesive according to the adhesive used. Assembly of plastic processing The assembly of plastic parts into a complete product is carried out by means of bonding, welding and mechanical joining.
The molding of plastic processing forms various shapes of plastic into articles or blanks of a desired shape. There are more than thirty methods of forming. Its choice depends mainly on the type of plastic, the starting form and the shape and size of the product. Common methods for processing plastics in plastics include extrusion, injection molding, calendering, blow molding, and thermoforming.
