Hi everyone, I’m working on a small pump housing for a chemical metering application. The part will be injection molded in PEEK, exposed to roughly 180 °C fluid and aggressive solvents. It’s a compact geometry (80 × 50 × 40 mm), with an internal channel and 3 mm wall thickness, but I’m worried about warpage and stresses. I’ve read that PEEK needs at least 2 mm uniform wall thickness, generous radii, and symmetry to reduce voids and warping, but does anyone have practical experience with these tips on similar parts? Especially in chemical pump housings, what gating strategies, wall tweaks, or cooling methods helped you minimize distortion?
