Component Specifications * 4.5 inch diameter, 24:1 L/D High Torque Extruder Section * Conventionally flighted feedscrew machined from SAE 4140 steel with flights hard surfaced with Colmanoy 56 for wear resistance. * The gear reducer used on the Hartig high torque extrder is a fixed ratio design UNIX 7.1 for compactness and ease of maintenance. It is rated at 250 HP at 100 RPM with a 1.6 service factor for extended life. * The thrust bearing used to absorb the thrust load generated by the feedscrew is a high quality Timken T-811 with a B-10 life of 269,900 hours at 5,000 psi and 100 RPM. * Our tangential opening feedthroat is a proven design supplied on all Hartig extruders. It is designed to assure positive feeding of virgin and virgin/regrind blends and is machined of high strength ductile iron. It's construction provides a core for water cooling. * Attached to the feedthroat is a high flow hopper system engineered for bridge-free operation. Each hopper has a dump chute for quick material change and a sight glass for visual level indication. * The extruder barrel is fabricated from SAE 4140 steel with a xaloy liner matched to the Hartig feedscrew for extended production. All barrels are pressure rated 10,000 PSI. * Extruder temperature control is provided over the entire length of the barrel. The extruder is divided into four (4) zones of finned cast aluminum heaters for heating and individual high air volume blower for cooling. The barrel and heaters are covered with insulated guards. * The extruder drive is a highly regulated 250 HP D.C. SCR package with a 1750 RPM motor which provides constant torque to the feedscrew. Included in the system is an open drip-proof motor, cooling blowers and intake filters. All drive controls are conveniently mounted in the main blow molder control panel. The drive operates under 460 volt, 3 phase, 60 cycle current. Accumulator Head - 33 pounds HDPE - 42 pounds engineering materials * The Davis Standard spiral accumulator head's unique design produces a parison void of a continuous knitline through it's wall. This allows the utmost in structural integrity while producing a very uniform wall thickness. As a direct result, finished products can usually be light weighted for a significant material savings. * Our tandem hydraulic system assures a uniformed alignment of the ram and tooling forces for long, trouble free operation. Through the use of this system, the inner cylinder strokes the tooling while the annular outer cylinder strokes the ram. * Shot size 33 pounds HDPE, 42 pounds engineering materials * Drop rate maximum 7 pounds/second * Ram stroke 7 inches * Tooling cylinder stroke 2 inches * Tooling diameter (minimum) 6 inches * Tooling diameter (maximum) 18 inches * Total heater KW 59 KW * Includes one set of head tooling. Press - 48 inches wide X 72 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 parallel, 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, Hartig's 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 front 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 hydraulic interlocks 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. Additional specifications: * Clamp tonnage: 200 tons (expandable to 300 tons) * Maximum platen opening 96 inches * Minimum platen opening 18 inches * Motorized vertical height adjustment +/- 5 * Side to side adjustment * Press wheels on track * Manual press shut height adjustment 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 Lumitech display panel for control of the following functions: * Control temperature on all zones displayed via operator's station. 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. * D.C. drive controls * Amp meter * Tachometer * Variable speed control * Motor starters for all hydraulic AC motors * Mercury contactors on heat zones * Fuse block and fuses * Control transformer Hydraulics * The Hartig hydraulic power system was designed and developed to work efficiently to operate the press, accumulator head(s) and auxilliary functions. * The power untit is floor mounted with integral drip pan, sight level guagees, and for ease of maintenance all port and valve designations are stamped on the manifold. Oil cooling and 3 Micron system filtration is accomplished through a separate kidney loop and filter bypass alarm. Low oil level and high oil temperature alarms are also included. 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 valve's 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 guage, pressure guages, and for ease of maintenance, all port and valve designations are stamped on the manifold. * AC horsepower 50 * Main pump GPM 32 * Accumulator size 60 gallons * Reservoir capacity 200 gallons * System filtration 3 micron Pneumatics * Includes required regulators, filter and valving for air blow and pre-blow. Base * Main base is a unitized construction and serves as a mounting platform for extruder and accumulator head. Stairs and diamond plate catwalk are provided for maintenance and set-up of extruder and accumulator head. Plus more! LOADED WITH OPTIONS! * Retractable top blow pin assembly * Part stripper plates * Mold cooling water manifolds * For single head (4) 4-station manifolds: 8 zones in-8 zones out * Motorized press rollout * Motorized press height adjustment * Control cabinet air conditioner * Amp meters mounted on control cabinet for each heating zone * Light over hydraulic power unit * Tooling stand * Air receiver tank assembly, 240 gallon, connected and mounted to the machine frame including pressure guage, safety valve and regulator * Hopper magnet, drawer type * Rupture disc limit switch * Pneumatic hopper shutoff * 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 * 4 station hydraulic manifold utilizing directional valves for auxiliary functions for dual heads * 4 station pneumatic manifold for auxiliary functions for dual head
