SPIROL-HEAT-ULTRASONIC-INSERTS
SPIROL — Hole design for heat / ultrasonic inserts
- Source scope
- Heat/ultrasonic inserts in plastics; explicitly declared host, headed host or mating component.
- Implementation in Prufi
- Screens selected straight flat-bottom blind depth against insert length +2 pitches, and selected mating through-hole between screw major and insert pilot diameters. No retention, screw bottoming or assembly qualification. Headed host: counterbore diameter is head diameter +0.5 to +1.3 mm inclusive, depth at least head thickness. One assessed valid solid; selected larger full inward mouth cylinder, perpendicular planar entry, exactly two-edge annular seat connecting one smaller full coaxial inward bore with planar floor or exit. Reject chamfers, intersections, split cylinders and extra recess levels. No insert retention, assembly, load or installation certification. PRU182: explicitly declared straight heat/ultrasonic insert in a plastic host. One complete selected inward cylindrical/conical wall with selected perpendicular planar entry and flat disk floor or through exit; no extra coaxial voids or trimmed/split/intersected walls. Included angle is twice absolute cone semi-angle and must not exceed 1 degree; entry must be at wider end. Counterbores and countersinks remain unassessed. Separate 8-degree tapered insert style is not checked; no installation or retention qualification.
