Solvent Solvents soften surfaces of plastic (plastic must be soluble)—best for amorphous or low crystalline plastics, such as ABS, acrylic, cellulosic, PC, PS, PPO, and vinyls. Venting Guidelines by Resin • PC: .001"–.002" depth & .250" width • PC/PSU: .002"–.003" depth & .250" width • PES: .003"–.004" depth & .250" width • PEI: .001"–.003" depth & .250" width • PP: .001"–.002" depth & .250" width • ABS: .0015"–.0025" depth & .250" width • PEEK: .002"–.004" depth & .250" width FIGURE 40 - Venting Guidelines Vent Groove Vent Land Vent FIGURE 44 - Venting guidelines FIGURE 43 - Venting areas 20 Gravi-Tech CHAPTER 5 | PROCESS OPTIMIZATION Process optimization ensures a quality process and minimizes cycle time.
