Injection blow molding is a kind of blow molding method which combines injection molding with blow molding. Firstly, the mold with bottom is produced by injection molding, and then the mold is transferred to the blow mold for blow molding. Injection blow molding is the first step to produce the mold embryo. The injection agent injects the melt into the injection mold with the blowing core tube to form the mold embryo with the bottom, and then transfers it to the blowing mold of the blowing station through the mechanical device for blowing; After that, the mold is inflated, the blow mold is closed, and the compressed air is introduced into the mold through the mandrel air hole. The mold is tightly fitted with the blow molding cavity under the action of air pressure, and then transferred to the demoulding station after cooling; Finally, the product is demoulded. At the demoulding station, the product is ejected from the mandrel or directly sent to the packaging position, and then the next cycle of production is carried out.
1.High efficient mixing of PET special screw, with ceramic heatingring,significantly improve the melt glue speed and injectionyolume.
2.Reduce the plasticizing temperature and the AA value.Effectivelyimprove the contraction problem of products, improve thetransparency.3.The servo control system saves 30%~50% power better than theconventional machine.4.Variable pump control system saves 20%~30% power more thanconventional machine.5.Special coated chrome PET screw with large aspect ratio, fullymeet the requirements of PET transparency and plastic qualityprevent accumulation material, easy to clean.6.Large top output and top stroke meet the needs of PET bottle
embryo molding.
PET series bottle embryo special injection molding machineSpecial plasticizing system is designed for PET formingcharacteristics. According to the characteristics of PET moldingand the design of special molding system, the machinespecifications are complete, suitable for a variety of differentbottle embryo selection.
This machine adopts European injection blowing technology and domestic injection blow advantages.
Advantages:
1. Down-setting the clamping cylinder ensures the product clean.The mold chucking force is kept balance and uniform.
2. Decreasing the machine height ensures the easy operation of settling molds.
3. Particular hydraulic servo system and reasonable layout of the pipeline keep the machine running high efficiency and energy-saving.
4. Particular pressure clamping structure increases the clamping force and reduces the energy consumption of system.
5. Servo rotation system or high precision indexing device highly increases the rotation precision and reduces the dry cycle time.
6. Special double cylinder horizontal valve plate superimposed injection system not only makes the injection and storage smoother and faster, but also make it with good appearance. Particular plastic components meet the multi-level injection and pressurized requirement for different products.
7. Optimized internal rack layout keeps the maintenance more convenient.
8.De-molding is adopted with digital sensor detection and added with mandrel rotary detection function, which realizes the goal of full automatic operation.
9.Adopt the function of air pressure detection. When the blowing pressure below the set pressure, the equipment alarm and stop automatic, to reduce the rejection rate in the process of automatic production.
10.Adopt the function of cooling water pressure and temperature detection, when the cooling water pressure and temperature abnormal, the equipment alarm and stop automatic, to reduce the rejection rate in the process of automatic production.
11.Adopt the function of auxiliary alarm and host communication, when the host detect auxiliary police, it stop automatic.
12. Optional air-conditioned function for mandrel shortens the cooling cycle time to prevent the mandrel and material from sticking together.
13.The converyor belt backed can be connected with the visual inspection equipment, to detect the bottle body foreign, the material shortage, the irregularity, etc…to realize automatic operation.
14.The conveyor belt can be connected with the Visual Inspection, Leakage Tester and Labeling equipment, etc…
This process is ideal for producing large quantities of small plastic refined containers ranging from 5ml to 1L, as well as wide mouth containers used for cosmetics, daily necessities, medicine, and food packaging bottles.
