Product catalog summary

Injection Unit Specifications:
The document outlines the specifications for three different injection units (A, B, C) with varying capacities. The maximum injection capacity ranges from 38 oz to 130 oz (1,077 gm to 3,685 gm). The theoretical displacement varies from 68.9 in³ to 243.1 in³ (1,129 cm³ to 3,984 cm³). Maximum injection speed is consistent at 14.34 in/sec (364 mm/sec) for the first set and 20 in/sec (506 mm/sec) for the second set.

Injection Performance:
Maximum pressure and rate combinations are provided, with pressures reaching up to 34,800 psi (2,400 bar) and rates up to 200 in³/sec (3,276 cm³/sec). The document specifies maximum pack pressures and pull-back forces, with the latter being consistent at 25,000 lbf (111,205 N) for the first set and 22,000 lbf (97,860 N) for the second set.

Extruder Specifications:
The extruder L/d ratio is 30:1 for 70mm and 25:1 for 120mm, with performance speeds of 265 rpm and 131 rpm respectively. Barrel heat capacity is noted, with the number of pyrometers and total heat capacity specified.

Clamp Specifications:
The clamp tonnage is 550 tons (500 tonf), with maximum daylight of 67.72 in (1,720 mm) and mold height ranging from 9.84 in to 33.09 in (250 mm to 840 mm). The maximum mold weight is 16,300 lb (7,400 kg), and the maximum clamp stroke is 34.64 in (880 mm).

Machine Specifications:
Dimensions and weights are provided, with lengths ranging from 413.7 in to 439.0 in (10,508 mm to 11,152 mm) and shipping weights from 65,000 lb to 77,500 lb (29,484 kg to 35,155 kg). Machine requirements include water at 6 gpm @ 50 psi and air at 80 psi @ 20 cfm.

Electrical Specifications:
The input power source is 460 VAC ± 10% 3 Ph 60 Hz, with power supply capacities ranging from 108.5 kVA to 217 kVA.

Additional Notes:
The document includes notes on available options for increased eject force and speed, as well as other capacities and configurations. It also mentions that all machine dimensions and specifications are subject to change and are for reference only.

Diagrams and Templates:
The document contains diagrams and templates illustrating various dimensions and configurations, including robot mounting holes and feed throat dimensions. These are provided with both inch and metric measurements.
