The details of the processing of plastic granulators are relatively rare, and the plastic granulators produced by Shuliy Plastics Machinery Co., Ltd. are widely used, and their performance and quality are also excellent, which is deeply supported by customers. Accreditation, so this article is the Shuliy Machinery Factory combined with its own years of experience and some of the knowledge on the network to organize and summarize, for your reference and reference.
In addition to polymers, plastic granulator processing ingredients, plastic granulator processing materials, generally also add a variety of plastic additives (such as stabilizers, plasticizers, colorants, lubricants, reinforcing agents and fillers Etc.) to improve the molding process and the performance of the product or to reduce the cost of the product. The additive is overmixed with the polymer and uniformly dispersed into a powder, also known as a dry blend.
The history of plastic granulators can be traced back many years, and the processing of plastic granulators has evolved with the development of synthetic resins and has been promoted with the development of plastic machinery. After the birth of celluloid, because of its flammability, it can only be formed into a block by molding, and then mechanically processed into a sheet. The sheet can be processed by thermoforming, which is the earliest plastic granulator.
Casting is a successful injection molding process with the advent of phenolic resin. It is used in the processing of cellulose acetate and polystyrene. In the middle of the year, the development of soft polyvinyl chloride extrusion molding, plastic-specific single-screw extruder Correspondingly, the twin screw extruder was put into production the following year. At the beginning of the year, polyurethane foam was produced and blow molding technology was used to produce polyethylene hollow products. The introduction of reciprocating screw injection machines has brought injection molding technology to a new stage.
In the years, the newly developed plastic granulator processing technology includes various new reinforced plastic molding methods, such as winding, pultrusion, sheet molding, reaction injection molding, structural foam molding, profile extrusion, sheet Solid phase forming and co-extrusion, co-injection, etc. In the late years, the processing of plastic granulators was moving toward high efficiency, high speed, high precision, energy saving, large-scale or ultra-small, ultra-thin, etc. Computer technology entered this field and improved the processing technology of the whole plastic granulator to a new one. Level.
The first two processes of plastic granulation machining. The ingredients are the basic part of two plastic granulation machining. Below I will introduce the molding, machining, joining, surface modification and assembly of plastic granulation machining. An article or blank of the desired shape is formed. There are more than thirty molding methods, and the choice depends mainly on the type of thermoplastic or thermosetting starting form of the plastic and the shape and size of the product.
Plastic granulation Mechanical processing of thermoplastics commonly used in extrusion, injection molding, calendering, blow molding and thermoforming, plastic granulation mechanical processing thermosetting plastics are generally molded, transfer molding, but also injection molding. Lamination, molding, and thermoforming are the shaping of plastic on a flat surface. The above plastic granulation mechanical processing method 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, and are transferred to the parts. Many household appliances, building products, daily necessities, etc., use this method to obtain patterns such as metallic luster or wood grain.
Plastic granulator processing generally includes plastics in the formulation, molding, machining, joining, modification and assembly. The four processes after the processing of the plastic granulator are carried out after the plastic has been formed into a product or a semi-product, which is also called secondary processing of plastic. Plastic granulator processing is a general term for various processes for converting synthetic resin or plastic into plastic products.
