JUST AVAILABLE! 1993 HARTIG (Davis Standard) SINGLE 20 POUND ACCUMULATOR HEAD BLOW MOLDER IMMACULATE! IN CLEAN ROOM! HARTIG (Davis Standard) MODEL SMP-3515-3840-MCP 140 TON SINGLE PRESS BLOW MOLDING SYSTEM EXTRUDER SECTION: * 3 inch 24:1 L/D Hartig High-Torque Extruder driven by a D.C. drive motor * Extended Deep Grooved Feedthroat and zero compression screw, 125 HP Drive, for 2-5 HLMI PE. Hartigís advance design high performance conventional feedscrew machined from SAE 4140 steel with Colmonoy hard surfaced flight lands. The screw is rated at 700 PPH of HDPE. * Reducer DH-200 has a rating of 174 HP at 100 RPM with a 1.0 service factor * Thrust bearing is a Timken T-611 with a B-10 life of 242,000 hours at 5,00 PSI and 100 RPM * Intensively cooled grooved feedthroat - This efficient feedthroat provides the high feeding forces required for low temperature processing of todayís high molecular weight polyethylenes as well as fractional melt HDPE's * The barrrel is fabricated from SAE steel with bimetallic liner and has a pressure rating of 10,000 PSI. A safety rupture disc is supplied at the discharge end. The barrel is divided into three (3) zones of ceramic heaters for heating and individual high air volume blowers for cooling. The barrel and heaters are covered with insulated guards * Extruder drive is a 125 HP, D.C. SCR, 1750 RPM constant torque system. It includes an open drip-proof motor, cooling blowers and filter. All drive controls are mounted in the main extruder control panel. 460 volts/3 phase/60 hertz PRESS - 38 INCHES WIDE BY 40 INCHES HIGH CLAMPING SECTION (M.C.P.) * Hartig's press designs are based on the unique principal of pulling the molds closed to achieve full clamp tonnage. This concept allows all custom Hartig presses to bring the mold faces in parellel, as the end frames have no load on them * The platens are closed in high speed with individual, small bore cylinders to minimize oil flow for maximum efficiency. High pressure clamping is accomplished by rotating knuckle clamps which, when engaged, pull the molds closed. These short stroke, large bore cylinders generate high tonnage, but with little oil flow. This method assures no deflection of the end frames and no axial stressing of the tie bars * Further, Hartigís MCP has platens which ride on ways. This takes the dead platen and mold weight off the tie rods to further assure no deflection takes place to disturb parallelism * To bring the platens together on center repeatedly, dual chain synchronization is applied. Mounted out of the press working area, the adjustable chain systems are located on the fromt and back of the platens so that forces are distributed equally. Easy adjustment can be made for off center close or adjustment * Also, standard on all presses is a safety system of electrical and hydraulicinterlocks as well as whiskers to sense if an operator is in the press area. Emergency stops are located at five points around the machine and the entire press area is enclosed by expanded metal. This assures that all pinch points are guarded for safe operation SPECIFICATIONS: * Clamp Tonnage 140 Tons * Maximum Platen Opening 52 inches * Minimum Platen Opening 15 inches * Manual Vertical Height Adjustment +/- 4 * Side to Side Adjustment * Auto Presss Gate Opening and Closing HYDRAULICS: * The Hartig hydraulic power system was designed and developed to work efficiently to operate the press, accumulator head(s) and auxiliary functions * The SMP power unit is a bladder accumulator based system which is charged by a pressure compensated pump. A gear pump is piggybacked to the main pump to provide oil cooling, system filtration and to supply the main pump with oil. The filter has a bypass alarm and tank is equipped with low level and high temperature alarms. Additionally, a shell and tube heat exchanger is outfitted with a water saver valve * Valving is cartridge type for the highest oil flow and fastest response of any valve design available today. Due to the cartridge valveís design, the wear characteristics are far superior to that of spool valves. All valves are manifold mounted and utilize electrical connectors with integral LED's and surge suppressors * Press and ram speed are independently proportionally variable through the MACO 8000 for tight process control and shock-free performance * The power unit is floor mounted with integral drip pan, sight level gauge, pressure gauges, and for ease of maintenance, all port and valve designations are stamped on the manifold * AC Horsepower 75 * Main Pump GPM 47 * Accumulator Size 60 Gallons * Reservoir Capacity 150 Gallons * System Filtration 5 Microns PNEUMATICS: * Includes required regulators, filter and valving for air blow and pre-blow ACCUMULATOR HEAD: * One(1) Hartig 20 pound Accumulator Head designed for 20 pound shot with a first-in, first-out flow configuration providing optimum parison uniformity. The unique co-axial dual hydraulic cylinders provides a rapid parison drop and high precision parison programming * The tooling size range is 18 inches diameter maximum and 4 inch diameter minimum * The head is designed for rapid color change, ability to process difficult materials, and air passage for top blow CONTROLS: * The control panel is a three-door NEMA enclosure with main power disconnect shock mounted on the unitized base wired 460 volts/3 phase/60 hertz. The following components are included: Barber-Colman MACO 8000 Microprocessor control system with Color CRT for control of the following functions: * Control temperature on all zones displayed via operatorís station. (Up to 96 zones available) The system provides independent zone temperature control and can be independently tuned * Total machine sequential control up to 100 independent timer functions available depending on number of sequence modules in system * Solid state cartridges for program and control parameter storage * Parison process control with individual weight and die gap settings and graphic display of profile setpoints * The exclusive use of individual control modules allows initial system to be easily expanded to meet future requirements * Sequence control is accomplished by the use of an IBM or IBM compatible personal computer using industry standard JIC graphic symbols BASE: * Main base is a unitized construction and serves as a mounting platform for extruder and accumulator head. An access catwalk and stairs are provided for maintenance and set-up of extruder and accumulator head Following are included: * Machine HAS front discharge * Press rollout to the left side as viewed under part remover facing head * Extended Deep Grooved Feedthroat and zero compression screw, 125 HP drive (required for 2-5 HLMI PE) * Single bottom blow stand, hydraulically adjustable, up and down (no spread device) * 4 station hydraulic mandifold utilizing hydraulically proportional valves for auxiliary functions for single head * One (1) automatic part removal system consisting of top part grabber utilizing cooled fingers to grab the parison and remove it from the press. This entire assembly is cantilever mounted to machine frame to allow unlimited access to press * Press on wheels with track * Powered press rollout, motorized * Motorized press height adjustment * Automatic press shut height adjustment * Color screen CRT. Mounted on left column support between part remover and rollout press * MACO 8000 serial interface * Light curtain in lieu of pneumatic safety gate * Water Manifolds (similar to Rubbermaid) * The machinery is painted standard Battenfeld-Hartig Gray.
