Automotive interior sheet extruder production line
Plastic packaging sheets are mainly used to produce disposable plastic cups, plates, bowls, dishes, boxes and other thermoformed products, which are widely used in food, vegetables, fruits , beverages, dairy products, industrial parts and other fields of packaging. With the growing domestic demand, packaging plastic thermoforming sheets are becoming more and more widely used and their usage is increasing year by year. The prospects are promising. With the country's emphasis on environmental protection, the environmentally friendly degradable sheet production line adapted to the production has been able to successfully supply various types of degradable sheets to the market. Nanosheets made of nanoplastics have become another focus of attention and a new selling point for
manufacturers. In order to improve the shelf life and shelf life of food, sheets with high barrier properties have become the goal of various production companies to compete for development. [] Production method of automobile interior sheet extruder production line
Common methods for producing plastic packaging sheets include calendering method, which is mainly used to produce D and other sheets, and the other is extrusion method, which is used to produce,,, , and other sheets. The sheet mentioned in this article mainly refers to the sheet used for thermoformed packaging products produced by the extruder-type die-three-roller calendering device-coiling process. The domestic sheet machine production industry continues to introduce advanced configurations and new machines with the development of packaging sheets. Over the past decade, sheet production and sheet machine manufacturing companies have cooperated with each other and introduced jointly, which has also improved the overall development level of the industry. New sheet processing technology and new raw and auxiliary materials are fully utilized in the configuration of advanced equipment.

Development trends
The gradual improvement of the domestic sheet machine manufacturing level has promoted the increase of domestic plastic sheet production enterprises and the diversification of sheet varieties. It has also promoted the unprecedented prosperity of the thermoforming packaging industry. The development of my country's sheet machine industry generally has the following trends:

1. A single separate single-screw extruder is configured with a vertical three-axis extruder. Roller sheet production lines tend to be saturated. Most domestic companies have this type of sheet production line, which has made great contributions to each company's early occupation of the market, accumulation of funds, and technology development. The sheets it produces can basically meet the production requirements, but the sheets produced with it, especially the production sheets, cannot produce satisfactory gloss levels. The technology of this kind of sheet machine is quite mature. It is easy to assemble, easy to purchase parts, simple to configure, easy to operate, cheap and has low maintenance costs. It has become a more popular model. Fierce competition has forced some sheet machine manufacturers to switch to other products. For example, Beijing Sheng'an has focused its efforts on the development of aluminum-plastic composite panels and Shantou Dacheng is moving towards a higher-grade sheet production line. There are also some manufacturers that have switched from sheet machine production to sheet processing, plastic cup manufacturing, blister and other industries. This sheet machine can be used to process sheets, egg tray sheets, packaging sheets for blister packaging, etc. If the calender roller is replaced by an air knife, thinner blister sheets can be produced. However, at present, most of this equipment in China is not equipped with this device, which brings a lot of inconvenience to production companies and restricts the development of companies in the field of sheets and molded products to a certain extent.

2. Among the sheet production lines configured with a single extrusion unit, my country’s first electromagnetic dynamic extruder has been successfully used in the sheet production line. It has It has the advantages of energy saving, material saving, uniform plasticization, etc. It can produce a variety of materials at a low price. This kind of extruder with Chinese characteristics should be vigorously promoted and continuously improved, equipped with advanced follow-up equipment and control systems, and launch our own advanced production lines in China to the world to get rid of the development state of always following others in changes. For example: Shantou Weida has launched a number of such sheet production lines on the market and the market response has been good.

3. The sheet machine configured with a single exhaust-double-stage single-screw extruder is a new type of sheet machine launched by the equipment manufacturer to cooperate with environmental protection. Material production line. After many arduous experiments and improvements, Shantou Dacheng and Xi'an Wanjie successfully trial-produced biodegradable sheets with a starch content of up to 50%. Many domestic companies have used Xi'an Wanjie's starch degradable materials to produce environmentally friendly degradable sheets and thermoformed products on Shantou Dacheng's degradable sheet production line. The prospects are promising. This sheet production line can process highly filled/sheet materials, light/biodegradable sheets, and biostarch degradable sheets. However, domestic degradable plastics are not fully degradable materials that contain plastic components. In addition, the proliferation of a wide variety of degradable materials, coupled with the competition from pulp molded products and the impact of the resurgence of foam lunch boxes, the market situation of degradable thermoformed products is not optimistic.

4. In order to reduce costs and control the market, companies that produce degradable sheets purchased a granulation production line and used a twin-screw granulation production line to supply their own degradable sheet production lines. Plastic packaging companies such as Shanghai Jinying, Xi'an Wanjie, and Xi'an Maxcon all have their own twin-screw granulation production lines. We believe that the production technology of degradable pellets on the market has matured and the price has dropped to very low. Enterprises that produce degradable sheets do not need to launch their own pelletizing production lines because there are already many pelletizing production lines with insufficient tasks or even idle equipment. In addition, some sheet machine manufacturing companies are developing twin-screw extrusion degradable sheet production lines. The purpose is to omit the intermediate process of granulation and directly use prepared powder to produce sheets to further reduce production costs. Moreover, this twin-screw extrusion sheet production line can also process high-filled calcium plastic degradable sheets as well as extruded, D and other sheets.

5. Resin blended transparent sheets have a tendency to replace transparent sheets and produce disposable containers instead of sheets. Since the sheets require special equipment to produce, most of the sheets required by thermoforming companies are purchased outsourced. In addition, the leftover materials cannot be recycled by the enterprises themselves and the price is very low, which increases the production costs of the enterprises. Another reason is that recycled materials can easily contaminate other plastics, so special attention must be paid during production, which brings some trouble to production operations. The sheets can be processed on the general extrusion sheet production line. The leftovers can be used by the enterprises themselves and can increase their own sheet production and reduce production costs. Therefore, some companies have begun to use sheets to make transparent drinking cups with good hardness and toughness, and some use them as covers instead of sheets. Sheet is - a blend of resin and resin. -The price of resin produced exclusively by Philip Chemical Company has gradually fallen. The possibility of it replacing sheet, sheet, sheet will further increase. Domestic sheet production equipment can also produce relatively satisfactory sheets.
