TG Series - SMC Extrusion Blow Molding Machine
Horizontal Clamping Movement and Proportional Valve Control

SMC DTG (Proportional Valve)

TG Series

Most are equipped with extrusion blow molding machines SMC series TG medium and large sizes cover the range produced up to 20 liters. TG machines are configured in an all-inclusive, meet the safety standard of the European Union CE and complies with the most sophisticated users.

External benefits of blow molding machines from TG line begins with a convenient operating panel, which concentrated all the controls and sensors, including the controller, as well as ergonomic design, in which the cabinets is integrated into the main frame of the machine, and easy access to the hydraulic system is made by simple opening of doors on the case. Pride Series TG - running elements lever knot closure.

The hydraulic system of Blow Molding Machines TG series with the working oil pressure within 150-220 bar focuses on the most effective work at the highest speeds are hydraulically powered movements while maintaining accuracy and repeatability of these movements.

The system provides a powerful work of axial piston pump Parker variable productivity. Managed Parker pump can operate with high productivity combined with high pressure, which is required for the implementation of truly high-speed hydraulic cylinders. In this case, the pump can be controlled to optimize energy consumption, to the intensity of the pump clearly coincided with the need of the hydraulic system in the new amount of oil under pressure at a time.

All movements of the machine (for the bogeys, closing / opening, supply / drainage blown Ornov, lifting / lowering of the extruder) are implemented proportional valves Bosch-Rexroth and Moog. Hydraulics is an adequately accurate execution of the specified machine with the controller schedules the rate of displacement 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 for the next cycle.

Modern proportional hydraulics, firstly, provides smooth and accurate movement (resource saving machines and molds; acceleration dry cycle), and, secondly, allows the use of the machine to 100%.

The system includes a hydraulic accumulator, a system of safety valves and two points of filtration (suction filter and filter-back). Components of hydraulic system supplied Bosch-Rexroth, Vickers, Moog and Parker, being used only original parts of these manufacturers. Support optimal (given) the oil temperature is carried out by a system of valve opens or closes the flow of cooling water in the oil cooler, and electronics, which monitors the actual temperature of the oil and filing the appropriate commands to the valve or stops the car completely in case of overheating oil.

Machine Features:

A Proportional valve control movement
A choice of machine controllers; Bechoff, Barber Colman, Moog and Siemens
Almost frictionless movement of the clamp and carriage by linear bearings and guide rails
Single station or double station machine production
Faster carriage movement than standard 3-tie bar machines
Increased multi-cavity production and longer clamp strokes
Accurate clamping force application due to equal force distribution on the platens
Easy access and convenience of adjustments on clamping platen
With compact design, robustly built, reliable performance and extended durability
Suitability of additional in-line equipments like
In-Mould Labeling (IML)
multi-layers (Co-Ex)
View Stripe (VS)
and Auto-finishing & trimming
Full conformity to CE safety regulations
