Potting machine uses abrasives resistant pump
Using a rotary pump design, a machine for filter end cap potting has no gears to wear and is resistant to abrasive fillers. Touch pad programming sets mix ratio and flow rates.
Technique simplifies production leak testing
Leak test technique simplifies and increases production leak test repeatability and selects the ideal fill and stabilization times based on the volume and temperature of the product.
The C-Spray answers the automotive, transportation and marine markets' demand to eliminate vinyl used in seats, instrument panels, and the like.
The sprayed on PU skin replaces the more expensive vinyl vacuum forming or upholstering processes associated with these types of parts.
An additional benefit is that an all polyurethane part is easier to recycle after these parts reach the end of their life cycle.

Six-axis robots to speed up moulding systems
Robots will become increasingly familiar in injection moulding processes as cycle times are reduced and post-moulding processes need to be performed more efficiently then ever before.
Injection moulder has clamping force of 4000kN
The largest injection moulder yet built by Arburg - with a clamping force of 4000kN will make its first international appearance at the Fakuma 2002 plastics exhibition, Germany October 15-19, 2002.
The C-Spray system features an impinge mix gun that is capable of circulating two component chemicals through the gun impingement rod and back to the supply reservoirs when not spraying.
This assures that pressures do not fluctuate and eliminates lead/lag.
Continuous flow, precision metering pumps are used which can create impingement pressures up to 3,000 psi (207 bar) and combined flow rates from 12cc to 40cc per second.
Heat exchangers between the metering pumps and spray head allow impingement temperatures to be stabilized at 150degF (65degC).
A unique control feature allows the operator to program the machine by use of a keypad and graphic display.
Either flow meters or a wet calibration station can be provided to control ratio and flow rate.
Various sizes of component tanks can be provided to fit the application.
In addition, an extension wand can be attached to the C-Spray gun to facilitate difficult to reach areas of a mold.
The Decker C-Spray RIM gun can be combined with a multi-axis robot to completely automate the spray process.
