... technologies for a reliable hold S-Lok®– threaded insert and stud ... The S-Lok is a threaded insert / stud with a graduated opposing herringbone knurl on the outside and a pilot end for problem-free insertion. Its unique shape has been tailored to the requirements of the material and was developed especially for insertion into plastic components by means of ultrasonic vibration or heat transfer. Well-known manufacturers of ultrasonic welding machines recommend S-Lok due to the low energy requirement, the short insertion time and the problem-free production. Design of the moulded component and receiving hole Installation Inserts are installed by means of ultrasonic or heat transfer. This causes the plastic to soften so that it flows into the knurl profile of the S-Lok. On subsequent cooling, a firm seat is obtained which is capable of withstanding high loads. Hole diameter (L) and wall thicknesses (W) are dependent on the material used for the formed part, the insertion method and the requirements imposed on pull-out resistance / torque safety. Please inquire or ascertain by testing. For guideline values, see the works standard sheets. The pull-out resistance is generally higher than is the case with mouldedIf the component offers easy mould in components, and depends on the removal, cylindrical receiving holes are plastic, the size of the receiving hole, recommended. For conical receiving the wall thickness, the edge distance holes: 0,5° to 4° (see Works Standard and the correct setting of the installa853/1 and 855/1 also 853 2 and 885 2). tion equipment. Product features • Also suitable for thin-wall thicknesses, elimination of material tension. • The firm seating is largely insensitive to borehole tolerances and material shrinkage.
