Parijat Aluminum Extrusion SCADA NGSH-0701

The goal for extrusion operations is to produce the highest quality product at the lowest possible cost. Securing this efficiently requires a change in paradigm from operators pushing buttons and manually collecting data – to presses running in complete automatic, performance and production data being collected and transferred to the business, ERP system, while the equipment operators function as technicians concentrating on improving quality and productivity. The MIS, ERP system may be an existing 3rd party system like SAP, Oracle Financials, M2M, InFor, MS Dynamics, Epics etc. or it may be the integrated business systems option of the Parijat system.

A Typical aluminum extrusion system solution consists of various software silos or islands from different vendors software products with multiple copies of data, also requiring a lot of manual data entry activities that are prone to human errors.

PCI solution combines all of these activities into a single software application with a single copy of data. This eliminates any data integrity complications & vulnerability to human data entry errors.


To get to this level, the press system – beginning with the billet / log heating and cutting system; billet loading system; press cycle, auto Die change; lead out table / hot saw / puller; profile handling transfer / stretching system; Cold / finish saw infeed, cutting, queuing, and offloading systems must be balanced; quenching air / water; PLC’s capable of communicating between themselves, running in automatic closed loop control mode and the PLC’s making process adjustments based on equipment settings, positions and computer algorithms all with minimal operator intervention. Examples of this type of automation are:

1. Automatic billet call settings based on press ram speed, billet length and dead cycle time.
2. Die Copy actual weight per unit length calculation based on puller positioning and billet size.
3. Automatic adjustment of billet length to maximize recovery, minimize press time.
4. Billet length calculations based on last recorded weigh per unit length of die copy.
5. Smoother & faster press cycle & smaller dead cycle time – even less than the press vendor spec.
6. Safety interlocks –
· Puller safety light curtains
· Hot saw protection
· Press safety alarms / stops – ram obstruction, billet misalignment, butt fall detection, short tool stack,
7. Auto generated shift reports & statistics – quantity of billets run, gross weight extruded, number of die changes, contact time.
8. Automatic burp pressure settings to minimize blisters, burp cycle.
9. Hot saw positioning in conjunction with billet length calculation to maximize recovery.
10. Automatic position / release of extrudate via recipe verses operator, or time controlled
11. Ram speed adjustments based on billet & exit temperature (Thermal camera/IR Pyro)
12. Finish saw automation, unattended operation after the stretcher trim is cut off so the saw operator can assist in racking metal.

Tracking & Traceability

Use advanced video analytics, Blockchain & IIOT (Industrial Internet of Things), Industry 4.0 to track & trace the materials used from entry of logs/billets to the finished products at plant exits.

Communications - data collection

Up till now data collection and analysis was quite arduous – many times data is not thoroughly collected or analyzed to determine what is preventing current system from running optimally – getting to root cause is the key. Even the oldest presses have the potential to run in full automatic or as a bare minimum semi-automatic. Parijat SCADA data collection system will provide with real time press performance and identify roadblocks to excellence. Parijat integrated single system will provide the cost savings models by modifying or correcting the issues which are keeping the press from being very profitable.

Once the press system is functioning at full potential, optimum recipes (press parameters) can be generated beginning with the highest volume shapes. These recipes get automatically pushed directly into PLC’s, once again reducing operator keystrokes and potential for human error. Infinite quantity & extensive recipe management system helps with the process optimization also. Parijat PLC programs & the PC software harness the full power of both sides coupled with the domain knowledge of Aluminum extrusion. This is done by focusing on total end to end Systems Integration:

  1. Develop drivers and software to cohesively integrate existing press PLC’s with existing business systems (ERP, MRP) or also perform those functions if an ERP system does not pre-exist as an integrated system.
  2. An extensive die management system to provide the tools to effectively analyze the performance of the presses down to the profile level, including automatic Die change over, if physical mechanisms exist.
  3. Presales quoting system – provide a quoting model which provide the production estimates and the optimum number of holes in a die. In a multi press operation this can be provided by multiple cost / profitability estimates based on different presses.
  4. Scheduling – provide easily manipulated Press Schedule – using existing ERP, MRP system. Including optimizing billet length, hot saw position, multi drags, multi push based on actual weight per unit length of theprofile.
  5. Collect – Labor, Burden, number of billets, length of billets, alloy, alloy lot number, actual weight per unit length of extrusion and run success based on PLC data communications without the need for the operator to input this data manually.
  6. Collection of “real downtime” or lost time – The following diagram shows time distribution of a typical extrusion 24-hour work day.
  7. Use of smart industrial buses like Ethernet, Controlnet, Devicenet, Profinet, IOLink etc.to significantly reduce wiring.

Parijat can help optimize the control systems and processes. 

There are a number of other services Parijat offers, beyond trouble shooting, optimization and integration.


Parijat team is fully capable of training client’s maintenance personnel on multiple PLC platforms – Rockwell, Siemens, GE, Schnieder, Mitsubishi, Honeywell, to name a few.

PLC Upgrades

if current press control system is running outdated PLC’s, Parijat can help upgrade it to the latest software and hardware available & harness their power to the fullest.

EMMT – Extrusion Maintenance Management Tool

this is an instant interactive, intuitive Visual fault diagnosis & trouble shooting tool for the maintenance team to trouble shoot equipment, without the PLC technician having to pull out the laptop and analyze the ladder logic. Parijat provides plant team members a virtual road map for trouble shooting which will significantly reduce system downtime by minimizing the trouble shooting of the equipment – EMMT points in the right direction.
