Also, has a very low coefficient of friction for easy installation, excellent flame retardancy and char formation.

All installations are computerized and are constantly monitored.

GETTING STARTED TIMING IS THE KEY TO A RUNNING COLOR CHANGE Hand Blend • Have the purge blend ready to load • If hopper contains a mixture of resin, color and/ or regrind, it should be run dry or drained before beginning the color change, keeping the screw full so press cycle continues • Run the main resin hopper dry or shut off hopper to hand feed at the throat • Once press is clean, slide hopper in place and proceed with next color-resin blend • The next color can be added while Cesa Clean is still in the barrel • When splay is no longer visible in parts, reset shot size, parts should be ready to pack (Single) Volumetric/Gravimetric Metering Unit at the Throat • Empty and clean feeder while press continues to run • Add Cesa Clean to the feeder color hopper and calibrate to a 3.0% use rate • When press is clean, start next color • When splay is no longer visible in parts, reset shot size, parts should be ready to pack • Note: If an open/unused secondary feeder is installed, use it for the Cesa Clean concentrate Central Blending Unit • Thoroughly clean unit while continuing to mold parts, keeping a resin feed to the press • Using a clean open hopper or regrind hopper, add the Cesa Clean concentrate • Set blender for additive/color to 3.0% • Once press is clean, drain hopper and/or central blending unit while continuing to mold parts • Begin new color and continue to mold parts • When splay is no longer visible in parts, reset shot size, parts should be ready to pack Process Adjustments That Can Help • Increase back pressure • Increase screw speed • Increase injection speed (in some tools maximum injection speed can facilitate cleaning) • Reduce mold close time (faster cycle) • Always remember a stock temperature of 400°F is essential When press and tool are clean, return all settings to standard production process profile.

Processing aids can be used to achieve an improved surface finish, expanded heat processing window, elimination of die drool, and higher line speeds.

Transfer using cavity pressure is expensive because it involves installing pressure transducers in the part cavity. Startup Issues To resolve startup problems, the material’s process window must be determined to ensure that there is a set of conditions that can make good parts.
