OH XPORT: THE SMART GUARDIAN FOR YOUR MOULD

OH Xport is a game-changer for PET and PAC producers. In hourly snapshots, it transmits a range of vitalmould performance data. This comprehensive production update is available on a secure data dashboard. Andif something does go wrong and the process is in danger, OH Xport transmits an urgent warning to operatorsby email or tweet.

The OH Xport System
OH Xport comprises a data control unit fed by several high-end sensors near the injection mould. The data gathered by the sensors is transmitted to a cloud platform via the mobile network, independent of any existing process monitoring systems. Our proprietary protocols transform this sensor data into straightforward visualizations and graphs that are stored on the secure data dashboard. One OH Xport unit feeds one data dashboard that can readily be accessed via smartphone or tablet. In addition to on-demand access, OH Xport units produce regular monthly reports.

And OH Xport does something more: it sends instant alert messages, by email orTwitter, whenever predefined process thresholds are violated. Downtime can be significantly reduced through proactive maintenance.

How OH Xport works

Advantages

  • The data dashboard provides transparency about daily production routines. Standard production settings such as clamping force can be fine-tuned on the fly, leading to substantial savings potential.

  • Sudden irregularities in production are quickly detected and communicated if they exceed pre-determined values. The affected production run can be inspected before delivery, reducing the risk of rejection by the customer, improving customer satisfaction, also leading to substantial savings.

  • Data captured by OH Xport enable well-timed maintenance. Equipment service life is significantly increased. Maintenance activities can be scheduled when they are really needed. Productivity and profits increase.

  • The close monitoring of critical items of equipment – for example, the hot runner – can detect clogging in the hot runner cooling circuit. The risk of a sudden hot runner failure, leading to large production losses and costly emergency repairs, is drastically reduced with OH Xport, another source of big savings.

  • Warranty extensions: Installing OH Xport units on new OH moulds and hot runners can increase warranty duration by one or two years!Up to 3 times longer equipment warranties.

Return on Investment
And OH Xport unit has potential to deliver savings of EUR 20,000–60,000 annually. At a cost of about EUR 15,000, an OH Xport installation will repay its investment in only three to nine months for many producers!

Using OH Xport
Process reports are automatically generated periodically as well as on demand. The report summarizes the current production status and condition of an injection machine, as well as evaluates the performance of up to ten different moulds and hot runners operated on a given injection machine.

What an OH Xport data dashboard tracks

Data point
Reason for current or most recent stoppage
Indication
Why and how long the machine is or was down
Benefit
OH Xport’s monthly report may show that certain breakdown causes repeat themselves, which indicates the need for process improvements.

Data point
Cycle time and Lock-to-lock time
Indication
Development of CT and LLT over time
Benefit
Tracking of short-term deviations and long-term trends

Data point
Shot counter
Indication
Shot counter, with progress over time
Benefit
Evidence of production stoppages, loss of production, visualization of long-term effects

Data point
Efficiency
Indication
Development of system efficiency over time
Benefit
Insights into short- and long-term efficiency. Efficiency benchmarking of two or more injection machines

Data point
Dewpoint inside machine production room
Indication
Temperature, humidity and dew point
Benefit
Immediate identification of A/C conditions that would allow condensation, prevention of condensate

Data point
Mould breathing
Indication
indicated mould opening at peak inject pressure
Benefit
Determining whether the mould breathing is within the target range. Instant alarm is sent if a potential problem is detected, allowing intervention at the octabin before releasing potentially defective products.

Data point
Hot runner condition monitoring
Indication
Cooling water flow and temperature for up-to five cooling circuits, surface-temperature
Benefit
Mid- and long-term trends help predict HR failures before they happen

Special feature preventive maintenance

Advanced Report*

An OH Xport’s Advanced Report cross-correlates data over time, yielding a highly useful record of production. Irregular situations are quickly detected. Traffic light alerts highlight potential trouble spots at a glance. Yellow or red traffic lights indicate where attention is required most. This valuable tool allows operators to prioritize their actions.

Product handling

Technical requirements
An Xport system requires a voltage of 100 - 240 VAC, as well as a uninterrupted access to a mobile network (3G or better).

Scope of supply
Delivery includes one OH Xport device system comprising a data control hub, a set of sensors and sensor cabling.

On-site installation
We perform the installation and commissioning and train relevant personnel. Machine down-time: about four hours.

Changing the mould
A mould change requires the staff to select the right mould from a choice on the screen. The respective mould data is loaded and data capturing resumes.

 

Data handling and security

Data capture
In order to protect a client’s production know-how, as little data as possible is collected. For this reason, OH Xport usually transmits only one data point per hour and signal.

Data transmission
OH Xport uses a data hub with its own SIM card to transmit the data to the www.thingspeak.com cloud platform, which is located in USA. OH Xport is a stand-alone system which requires no integration into existing IT networks.

Data integration
OH Xport data can be accessed via its cloud platform, If desired, the system can generate automated CSV-files for easy integration of its data into existing monitoring solutions.

Instant alert messages
OH Xport units transmit instant alert messages via e-mail or Twitter to approved users. This function is available for mould-breathing and dew point alarms.

Secure production
OH Xport is only connected to a production process through its sensors. It only reads the information it is intended to read. It exerts no influence on production. Thus, OH Xport offers no useful access to the injection machine or the robot to unauthorized hackers.

Data storage
All data is stored on the thingspeak.com cloud platform.

Operating cost
Otto Hofstetter AG pays thingspeak’s annual license fee for its cloud platform. Fees for data transmission are also paid by Otto Hofstetter AG for a period of two years.

Product maintenance
Depending on local conditions, the sensors may require some cleaning. Apart from that, the product is maintenance-free.
