SMC Injection Blow Molding Machine

IB - Injection Blow Molding Machine

Injection-blow molding machines are designed for the production of hollow plastic containers by injection-blow molding. These machines are essentially a hybrid injection molding and blow molding machines. They consist of the injection unit, where the pressure cast billet preforms, blow molding unit, where not had time to cool off from the preform blown out finished products, and block removal, where the chilled ready-made products are removed and thrown out of the car.

Machinery Series SMC IB optimal for mass production of small (5-100 ml) nonrectangular plastic container with no sharp edges and without handles. Approximate maximum diameter / width of one product with a minimum gnezdnosti - no more than 115-120 mm, maximum length (from throat to bottom) - no more than 180-200 mm. The most frequent use of injection-blow molding machines - manufacture of bottles of 5-30 ml of pharmaceutical.

Principle of operation and modification

The central part of the machine - a triangular rotary table. One side of it is the joining node and the mold for molding preforms, on the other side - the joining node and the mold for blowing, and the third party is a section for the release of products. This product is on special Dornach-Signs and move from section to section, together with the turns of the triangular table. Compressed air supply to the exhaust products is carried out directly from Ornov-marks. Blowing is carried out without longitudinal drawing preform length, that distinguishes this technology from the usual PET bottles.

Machines SMC IB available in three versions. Standard machines are designed for the manufacture of products from polyolefin materials (PP, PE), as well as PS (polystyrene). Special modification of a PC (polycarbonate) is different injection unit, a special modification of a PET, in addition to a special site of injection, supplemented by air-conditioning system of signs, which are located on the product.

Benefits of SMC IB for polyolefins in comparison with conventional extrusion blow molding technology

• Quality products
  By using a three-stage production and use of hot runner molds achieved the highest external characteristics derived products, especially in the processing floor, throat, lines, connectors, as well as the smoothness and flatness of the surface.
• Recurrence geometry
  Tolerances in the extrusion-blow molding is measured in absolute terms, rather than as a percentage of the product. This means that the product volume of 5 liters to 15 ml vial variation in geometric dimensions may have a similar meaning in fractions of millimeters, but it is clear that for small items such okloneniya entail negative consequences quite different properties in comparison with a 5-liter product, where they do not have any influence on further practical properties. It is for this reason, injection-blow molding machines are effective in the production of the smallest vessels.
• Waste-free production
  In the process of injection-blow molding machine is not technological Oblomov and runners, and, thus, all the downloadable materials on 100% recycled into the finished product. This avoids the cumbersome system of processing and the secondary waste loading. Also, there is no need domeshivat secondary material, which is usually slightly reduces the strength and appearance of the product.
• High performance
  With the ability to install large molds gnezdnosti (20) and the rapid rotational movements between the nodes casting, blowing and removal for small vessels is achieved truly outstanding performance to 7000-7500 units per hour. To achieve such performance in extrusion blow molding machines required a huge gnezdnost, and hence in terms of used area and power consumption efficiency of the injection-blow molding will be much higher.
• The stability of the process
  The process of injection-blow molding is not dependent on environmental protection machine, because injection material is inside the mold. The product is blown out of the blanks (preforms) a fixed weight, obtained by injection molding, due to what is a stable, quality and weight of the product.
• Clean production
  In closing nodes used graphite bushings under the direction columns that do not require lubrication, which means that around product does not accumulate grease.

Hydraulics machines, including hydraulic cylinders and clamping hydraulic system rotary table, is in a closed cabinet at the bottom of the machine. Thus, under any circumstances, the oil will have no contact with the product. In extrusion blow molding machine of the hydraulic elements (blowing station, a hydraulic cylinder parizon control) are in the upper part of the machine over the product.

Benefits of SMC IB for PET compared with separate production of preforms and blowing
Modification SMC IB under PET

• Reducing the cost of products because the price of the purchase preforms is its cost to the producer and its rate of return (usually not less than 30%).
• Full control over the production process, and hence on the quality of the product from the boot of PET-granulate to obtain the finished product.
• Lack of risk and, consequently, problems with irregular supply of preforms.
• Free choice and change the color of preforms / bottles.
• Total freedom of choice of geometric design and capacity optimization of weight, because no need to choose from mature markets nomenclature finished preform. In particular, it is important for the smallest product (10-50 ml), which does not actually produce preforms.
• In case the company itself pours preforms, and then blows out the very same product from them, it is added to the above advantages of saving space and electricity production at the facilities of the enterprise.

The hydraulic system of injection-blow molding machines SMC IB with a working oil pressure within 150-220 bar solves many problems. First, hydraulics ensures all traffic site of injection, and secondly, the work of the rotary table and the opening / closing of the two nodes of closing. The system is aimed at the highest intensity of all the movements (the cycle of injection-blow molding machines are usually located within 8.12 sec.) And the highest speed of these movements, coupled with smooth braking.

Served by four hydraulic axial piston pump Parker and two motors (two pump on the shaft of each of the engines). Installed power system machines SMC IB requires so intense dynamics of oil, that a separate pump is given only on the movement of oil on the oil cooler.

All traffic cars are sold through proportional valves Bosch-Rexroth, and the injection is carried out with high-precision servo Moog feedback. The controller lets you adjust the machine speed and endurance injection pressure in 12 stages on each of these functions, which can hardly be found even in the most high-tech thermoplastic. Hydraulics is an adequately accurate execution of the specified machine with the controller schedules velocity by measuring the progress of each linear motion potentiometer, with any performance is not the right vehicle movement in time and / or position the controller will adjust the valve settings.

The system includes a hydraulic accumulator, the system of safety valves and the point of filtering. Components of hydraulic system supplied Bosch-Rexroth, Vickers, Moog and Parker, being used only original parts of these manufacturers. The machine is fully consistent with the safety standard CE.
