The hollow molding machine is a thermosetting plastic molding machine with high efficiency

With the increasing requirements for packaging bottles for food, medicine, cosmetics and high-end daily necessities, products produced by extrusion and injection molding methods can no longer meet the requirements. How to deal with the single thermosetting plastic molding machine has also become a difficult problem for enterprises to move to new heights. To change the single mode of plastic molding equipment, the only way to integrate molding technology is to develop new molding equipment. Under this development trend, a fully automatic one-step injection, stretch, and blow blow molding machine came into being.

Fully automatic one-step injection, stretch and blow hollow molding machine, from injection embryo tube, stretch blow molding and demolding in one step, no flash, no nozzle material, few defects, perfect mouth, bottom, and seam line , More transparency and higher rigidity. Stretch blow molding products can be thinner than non-stretch blow molding products, so about 50% of raw materials can be saved. In addition to the above characteristics, one-step injection stretch blowing has the advantages of high speed, energy saving, and environmental protection.

The hollow molding machine produced by the company is made by digesting and absorbing the most advanced international models and making major improvements. It has obtained national patents and has the advantages of fully automatic, no waste, high efficiency, and the most energy-saving. As the preform is used for stretch-blow molding with the retained heat during forming, the advantage is that the cost of heating energy required for reheating is zero, the cooling time of the preform is shortened, and the miniaturization of cold water equipment is realized; Forming disadvantages, minimum forming steps; greatly reducing the cost of raw material handling. The transportation costs of PET bottles, preforms, and PET raw materials were comprehensively investigated. Example: Take a box of 19g 500mL water bottles as an example. If it is a 1m3 box, about 1024 bottles can be loaded. Approximately 9,280 preforms can be loaded. The raw materials can be filled with about 56421 bottles of raw materials. Since Jiaspeed injection, stretch, and blow molding machines form the product container directly from the raw materials, the transportation cost can be reduced by 98.2% compared with the bottle transportation cost, and can be reduced by 83.6% compared with the preform transportation cost.

Fully automatic one-step injection, drawing and blowing hollow forming turntable is driven by a servo motor to avoid contamination of the product by hydraulic oil; fully automatic control and simple operation; no human contact in the production process to ensure product cleanliness and hygiene; barrel temperature , The mold hot runner temperature is precisely controlled by PIT; the one-step injection (stretch) blow molding machine saves more money and human resources than the traditional injection stretch blow equipment; the machine has a compact structure, a small footprint, and saves space.

Plastic bottles are one of the largest plastic products in terms of production and sales, and the rapid development of its demand is inseparable from high-efficiency and high-performance hollow molding equipment (including molds). Because domestic plastic molding equipment still has a big gap compared with foreign equipment, domestic plastic molding equipment manufacturers can only follow the trend and strive to develop new plastic bottle molding equipment, and use fully automatic one-step injection, stretching, and blowing. Only by gradually improving the hollow molding can the gap with foreign manufacturers be gradually narrowed, and the market can fight against them and share a piece of the pie.

With the continuous development and progress of society, plastic products have become a daily necessities closely related to us. From machinery and equipment, household appliances, to folders, plastic bottles, etc., we can feel the ubiquity of plastic products. It can be said that most industries in modern society are inextricably linked with the plastics industry. As one of the largest plastic products in production and sales, the demand for plastic bottles is also showing substantial growth with the development of society. In this regard, domestic plastic bottle forming equipment manufacturers should take the rapidly growing demand for plastic bottles as an opportunity to understand the development pulse of plastic bottles, and strive to develop new, efficient and intelligent plastic bottle forming equipment, and strive to shorten the time and international advanced technology and equipment. difference.

The molding mechanism has a variety of types according to the needs of molded products. At present, it is mainly divided into compression molding equipment (compression molding), extrusion molding equipment (extrusion molding), injection molding equipment (injection molding), blow molding equipment (Hollow molding), calender molding equipment, etc.

At present, my country's plastic bottle molding is relatively simple. The high-efficiency thermosetting plastic molding machines on the market are basically imported from abroad. The relative lag of productivity and technology has affected the rapid development of plastic molding equipment. What the market needs is continuous development, progress and innovation. With the development of society, it is not difficult to find that single plastic molding can no longer meet the needs of the market. Extrusion molding equipment cannot be widely used in the processing of thermo-solid plastics, otherwise it will cause deviations in the size of the product; and the cost of injection molding equipment and molds is too high, and its cleaning is relatively difficult. These problems show that plastic bottle molding equipment The market needs to increase the molding rate and output, as well as the development of high-performance molds, and the main direction of its research and development is high-speed, high-efficiency, energy-saving, environmental protection and quality control.
