The production technology of blow molding tray is blow molding. The material is usually made of high-density polymer material with high density. The weight of production is up to 10T. The life of blow molding tray is better than that of injection molding tray. It has better endurance and better quality. It has the reputation of “not broken tray”. It can be operated under the condition of minus 40-zero 40 degrees; the scale manipulation can be used for 8 years. Blow moulding, also known as hollow blow molding, is a method of agile plastic processing. The tubular plastic parison obtained by extrusion or injection molding of thermoplastic resin is heated (or heated to a softened state) and placed in a split mold. Immediately after closing the mold, a compressed atmosphere is introduced into the parison to blow the plastic parison. It is inflated and adhered to the inner wall of the mold, and is cooled and released to obtain various hollow products. The production skills of blown film are very similar in principle to the blow molding of hollow products, but it does not use molds. From the point of view of the classification of plastic processing skills, the molding skills of blown film are usually included in the extrusion. Blow molding skills began in the second world war, used to produce low-density polyethylene vials. In the late 1950s, with the birth of high-density polyethylene and the development of blow molding machines, blow molding skills were widely used. The volume of hollow containers can reach several thousand liters, and some productions have accepted computer control. The plastics used for blow molding include polyethylene, polyvinyl chloride, polypropylene, polyester, etc., and the resulting hollow containers are widely used as industrial packaging containers. According to the parison production method, blow molding can be divided into extrusion blow molding and injection blow molding, and new ones have multi-layer blow molding and stretch blow molding.
Injection molding tray technology is injection molding, injection molding, also known as injection molding, it is an injection and molding molding method. The advantages of the injection molding method are fast production rate, high compliance, and automatic activation. The variety of colors and colors can be from simple to complex. The standard can be from large to small, and the product standards are correct. The products are easy to be upgraded. The parts with disordered shape and injection molding are used in the molding processing of mass production and disordered goods.
At a certain temperature, the screw is stirred and thoroughly melted, and the plastic material is injected into the cavity with high pressure, and after cooling and solidifying, a method of molding the product is obtained. This method is applied to mass production of distorted parts and is one of the main processing methods.
The injection molding machine is also called an injection molding machine or an injection molding machine. It is the main molding equipment for thermoplastic or thermosetting plastics using plastic molding dies to make plastic products of various shapes. Divided into vertical, horizontal, all-electric. The injection molding performance heats the plastic and applies a high pressure to the molten plastic to eject it to fill the mold cavity.
Injection molding trays Compared with blown trays, there is no long life of blown trays, and it is good to carry all the blown trays, but there are also injection trays with special contrasting trays and steel pipes. However, there is also a defect that the process is disordered, and it is necessary to wear steel pipes and caps.
The plastic waste bins produced by Liante Technology Co., Ltd. (blow molding tray manufacturers) are widely used in sanitation, property, schools, hospitals, etc. Plastic pallets have flat nine-legged, Chuanzi, Tianzi, mobile and other series. It is formed by one-time molding by blow molding process. It has the advantages of light weight, firmness, beauty, durability, easy cleaning, anti-static and recyclability. At the same time, the series of trolleys has also been favored and recognized by users. The development and processing of molds are numerous. Large and medium-sized enterprises maintain a good cooperative relationship.
