Lubrication is essential to machine maintenance. Equipment properly lubricated reduces wear and tear during production, ensures temperatures are in check with operational standards, minimizes corrosion and helps keep contaminants and pollutants out of the system. Organizations will allocate nearly half of their total maintenance costs to lubrication-related activities. The biggest of them all is deploying the oil change.
An oil change makes certain machines are running smoothly and prolongs engine life. There’s incentive to changing oil regularly. However, therein lies the issue. Performing an oil change is straightforward enough, correct? Not quite. For technicians and mechanics, the traditional oil change process is much more tedious and hazardous. The likelihood of making a mess or even worse can be a costly mistake. Equipment downtime, lost production, employee safety and environmental integrity are factors an organization will risk when conducting an oil change.
A traditional maintenance oil change is cumbersome. From heavy machinery and power generation equipment to fleets and municipalities, changing oil involves thorough training on procedures and equipment and utilizing an arsenal of tools, which bring a multitude of challenges:
You can’t just stop performing oil changes. What is the solution then?
Parker's QuickFit Oil Change System is unlike anything else available in the marketplace. It’s radically transformed oil changes with a faster, cleaner and safer approach that hasn’t been accomplished until now. QuickFit is revolutionary, yet simple with a three-step process to purge, evacuate and refill oil.
The architecture of QuickFit eliminates oil spills and greatly reduces safety hazards. This is achieved through an accessible, single connection point that allows oil to drain directly to the waste containment, and then can be used to extract the used oil from the filter and pump in new oil. The total number of steps in the process is reduced, which means a faster and safer oil change.
QuickFit combines ease-of-use with comprehensive functionality. Minimal training is necessary and maintenance is simplified as oil changes can be done efficiently and effectively. Productivity goes up while the chances of an error occurring during an oil change are greatly reduced.

Whether train driving is done manually or automatically, human being remains responsible for safety. Man is increasingly assisted by automatic means to control and communicate with his machine. This assistance is provided by systems called Human Machine Interfaces (HMI).
The objective of the HMI is to make the facilities more functional, better adapted to the environment and to avoid risks. For this reason, electronic systems are growing to benefit passenger and goods safety but also for the productivity of equipment.
In trains, the HMI are deployed on different mechanical components in the form of electronic systems. They can be placed on the mechanical components of a pressure circuit to monitor and control their operation.
The sensor is an element of the HMI more and more used in the architecture of mechanical systems of a train, especially in pressure circuits. The assembly of sensors on mechanical components allows precise control of movement in pressurized fluid transfer systems, thus improving safety.
These sensors are detection devices with signals that make it possible to bring intelligence to the control of the movement. They provide the data needed to foster a reactive and preventative environment. Position sensors, for example, make it easy to control the open or closed position of a valve on a fluid transfer circuit.
The use of a sensor with electrical or contactless technology minimizes the overall cost of implementing a secure mechanical system. Indeed, it allows to quickly and accurately detect the open or closed position of a circuit, without separate encoders and especially without additional mechanics.
The data transmitted by the sensor allows the monitoring and, when the information flows in both directions, the control of the mechanical component itself. Position data available improve risk control and prevention by quickly detecting any problem and saving it to databases. The HMI then makes it possible to avoid malfunctions that can lead to downtime or productivity losses.
Several fluids are circulating in a train between a tank and actuators such as brake shoes and motors. The medium conveyed range from compressed air, water or glycol water, to diesel or hydraulic oil. Some circuits need to be secured.
Well known for its expertise in fluid transfer solution, Parker Legris has developed a new lockable valve with sensor, adapted to the low-pressure circuit for compressed air supply. Thanks to this valve with open or closed position detection, the user quickly identifies the valve status and can act faster at the exact location.
This new Parker Legris valve has two additional functions:
To adapt to the railway equipment constraints, the new valves have a robust IP67 protection box at the sensor. They are 100 percent leak-tested and have an inductive sensor electrically connected to the HMI.
Electronic sensors are now essential safety instruments in railway vehicles. They are expected to expand to more mechanical components, because safety is at the heart of the innovation of railway market players, and more widely of manufacturers like Parker.

Lighter, versatile, non-corroding and cost-effective. These are some of the advantages as to why manufacturers are increasingly replacing metals with plastics for product development. Plastic injection molding is a key component in a shifting manufacturing landscape and has grown beyond specialty applications. Today, it’s a sophisticated process for producing parts requiring machinery and tooling of increasing complexity. As a result, injection molding operations are being pushed to the limits at a time when product quality and manufacturing efficiency is crucial to success.
Injection molding processes are exposed to a variety of potential risks over the course of production. From running unattended for long periods to equipment performance faults, operating without production monitoring can lead to real business headaches. Even the smallest of deviations or errors can impact an organization’s bottom line and result in significant ramifications including line downtime, increased scrap, late shipments and the biggest factor of all, a dissatisfied customer.
There are many variables affecting the injection molding process and each impacts product quality. The variations in temperature, humidity or machine pressure can lead to process or mechanical breakdown. By regularly monitoring the status and condition of processes and equipment, you’re able to identify potential problems and select a course of action to rectify it.
A continuous condition monitoring program provides a valuable amount of information for predicting machinery failure or process variation aiding in the analysis of the root cause of the problem. This solution provides reliable and useful data to assess the health and condition of injection molding machines and processes.
The following two case studies showcase how IoT-based condition monitoring solutions help injection molding operators solve production issues while increasing safety, productivity and quality.
A large injection molding company that produces components for the medical device industry struggled with maintaining the quality of a particular molded part. Production runs were inconsistent due to temperature and pressure anomalies in the mold injection lines, which resulted in short shot, or incompletely formed parts. This caused production downtime, as well as increased part inspections and scrap.
Accurate and continuous monitoring of the temperature and pressure lines with SensoNODE™ Sensors and Voice of the Machine™ Software revealed a small leak in a pressure hose that caused the pressure to drop at certain times during the molding process. With the hose replaced, SensoNODE and Voice of the Machine Software ensured the pressure remained stable during the process. In addition, data collection was much easier than utilizing standard gauges, which would be in difficult-to-see locations within the machine.
The injection molding company was able to fix the problem quickly, minimizing downtime and scrap. The company also avoided a serious product recall risk that comes from shipping out-of-spec molded parts to a medical device customer.
A customer that makes washing machines and dryers had been using manual diagnostic test tools for their manufacturing processes and machines where a majority are hydraulic-based assets. Two pieces of equipment in particular – an injection molding machine and a stamping press – are driven by the same hydraulic power unit (HPU).
The HPU is located 20 feet off the floor at the top of the machines. In order to diagnose or evaluate each asset, a maintenance technician must use a manual diagnostic tool connected to the HPU to collect pressure changes at several points of interest. A second technician would be on the floor watching and cycling the machine.
Those technicians would then test several points individually, which took hours. Because the manual diagnostic devices have long cords that connect the sensors to the handheld meters, the set up for testing was cumbersome and time consuming. Technicians would shut down the machine due to safety risks, then set up the tools to take readings, which further extended downtime and led to missed revenue opportunities.
The customer needed a solution that allowed a single maintenance technician to test multiple functions simultaneously as well as take readings from the floor while also observing asset processes.
By installing SensoNODE Sensors at each of the five points of interest, the technician is now able to run the machine and use Voice of the Machine Software to track all pressure measurements at once, as well as watch the machine functions from a safe area.
Being able to monitor multiple points at the same time simplifies the troubleshooting of a complex system, which helps technicians quickly resolve issues that minimizes downtime and saves money. In turn, the injection molding manufacturer’s customers receive quality products on time leading to increased satisfaction and loyalty.
