Cartridge filter machines get new
features
CPR cartridge filter assembly machines that revolutionised the production of medical and beverage filters with the use of precise control infra red, now have a host of new features
The CPR range of cartridge filter assembly machines which revolutionised the production of medical and beverage filters with the use of precise control infra red, now has a host of new features The addition of automatic loading to feed the three assembly end weld sites has pushed productivity through the roof, and 10" to 40" filters with polypropylene end caps of all varieties leaving the machine every 10 seconds

60% saving on plastic welding energy costs
CPR Automation has announced the introduction of their latest innovation in plastic joining technology, the Generation II Infra Red "CleanWeld", saving up to 60% on energy costs
Test rigs conforming to FDA standards
A specific request from one customer asked for a machine to flush and test medical filters using pure water or IPA, giving CPR a challenge, particularly making the design conform to FDA guidelines
CPR have utilised the high speed and accuracy from the Yamaha Industrial Robot range to automate the machines.
Establishing the actual depth of penetration into the end cap during the cooling phase is now possible, the addition of linear measuring transducers has allowed the machine to check the length of the un-welded assembly and compare it to the finished welded length and hence record the insertion distance.
The data is monitored to ensure that the quality of the product is maintained to the highest possible level, this data can then be output to SCADA packages or any other logging system.
The sophisticated control system developed by CPR now includes better temperature control which can be set from the touch screen HMI and is infinitely variable.
If, as is the case with Delrin end caps, the materials used have a small melt window, the latest CPR machines are available with AMC (Automatic Melt Control) where the face temperature is constantly monitored and the power varied to maintain constant temperature.
If these advances are not enough the option of inert gas feeds to the heating sites is available which speeds up the processing of materials like nylon which tend to discolour when heated too quickly.
These plastic welding techniques and designs are transferred to other products and many different industries are now benefiting.
