Company Overview: HESTA Blasformtechnik GmbH & Co. KG, located in Göppingen, Germany, has been known for its quality since 1948. They specialize in extrusion blow moulding machines.
Technical Specifications: The document provides specifications for two models of single station blow moulding machines, HG360 E and HG460 E, which are all-electric driven with a horizontal linear shuttle. Key specifications include:
- Linear mould stroke: 360 mm for HG360 E and 460 mm for HG460 E.
- Mould dimensions: Width and length are 360 mm and 400 mm respectively for HG360 E, and 460 mm and 400 mm for HG460 E.
- Mould thickness: 2x120±3 mm for both models.
- Clamping force: 120 kN for both models.
- Dry cycle time: 1.9 seconds for HG360 E and 2.1 seconds for HG460 E.
- Centre distances vary based on the fold configuration (2 to 8 fold).
Extruder Specifications: The machines feature extruders with diameters of 60, 70, and 80 mm, driven by electromotors with variable screw speeds ranging from 0 to 80 min¯¹.
Energy and Cooling Requirements:
- Electrical drives require 17.5 kW for 120 kN.
- Electromotor extruder power ranges from 27 to 54 kW depending on the model.
- Heating capacity ranges from 12.4 to 22.3 kW.
- Total connected load ranges from 58.9 to 95.8 kW.
- Air requirement is approximately 500 to 600 Nl/min with a working pressure of 7 to 10 bar.
- Cooling requirements for the extruder and blow mould vary, with maximum values of 12,000 kJ/h and up to 48,000 kJ/h respectively.
Additional Information: The document notes that technical specifications are subject to change without notice. Standard voltage is 3 x 380V, 50 Hz, and alternative centre distances are possible upon request.
