200 ton PVC plastic molding machine

Overview

Model BL200EKH-PVC by Bole Machinery is a horizontal Preform Injection machine for thermoplastic PVC with automatic, computerized control and SGS certification. Origin: Zhejiang, China. Type: Preform Injection; Structure: Horizontal; Plasticizing Way: Screw Type; Clamping Way: Hydraulic & Mechanical. Key injection and plasticizing specifications include screw diameter 45 mm with L/D 20.0, theoretical injection capacity 382 cm3, shot weight (UPVC) 458 g (16.2 oz), injection pressure 185 MPa, theoretical plasticizing speed 17 g/S (UPVC), injection stroke 240 mm, max. injection speed 124 mm/s and screw speed 130 r/min. Injection rate into Air is 197 cm^3/s and 236 g/S. Hydraulic and clamping data: clamping force 2000 kN, opening stroke 480 mm, space between tie bar 505×455 mm, min. mould height 200（165） mm, max. mould height 530（530） mm, max. daylight 1010（1010） mm. Ejector stroke 150 mm, ejector force forward 49 kN and back 37 kN, number of ejector bar 5 PC. Auxiliary and operational specifications: Sys. Pressure 17.5 MPa, Pump Motor (Min～Max) 16.4～23 kW, number of Motors 1 PC, heater power 12.2 kW, number of temp. control zones 3+1, dry cycle period 2.5 S, energy consumption level ≤0.5 kW.h/kg, hopper capacity 25 kg, oil tank capacity 230 L. Machine dimensions 5.2x1.4x2.2 m x m x m (with widened gate 5.2x1.6x2.2 m x m x m), machine weight 5.5 Ton, widensafety gate optionally (single side): 100 mm. International specification: 700. The machine includes special design features for rigid PVC: an enlarged hydraulic charging motor to improve torque and slow down speed, and a screw surface hard chrome plated with hardness above HRC65 for improved wear and corrosion resistance and longer working life. The Bole centre clamping structure is stated to provide 100% clamping force use (10%-20% higher than traditional toggle), reduce flash and flash trim work, save 2-5% material, offer protection to mould, platens and tie bars, and provide an opening stroke 10-20% longer. The machine is described as a PVC plastic molding machine with a special design idea for rigid PVC and is intended for preform injection of thermoplastic PVC. It is presented for PVC plastic molding applications, including UPVC parts consistent with the listed shot weight of 458 g (16.2 oz).
