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
