Plastic screws and plastic moulded articles

PT screws for thermoplastics: Thread rolling screws for direct screwing into plastics, Thread 30° or 60° KTG screws for thermoplastics: Single-start or double-start thread (high, low) Thread rolling screws are extruded for larger batch sizes and turned for small batch sizes (Turned parts for direct screwing) High tensile and highly stressable connection of thermoplastics with considerably longer life endurance Thread rolling without chips and loss of material Minimum radial tension, large thread coverage Process-reliable due to torsion strength Shorter and slimmer screws are possible. Materials: Steel, case-hardened Quenched and tempered steel 1.5523 tempered to 1000 +200 N/mm², high-grade steel 1.4567, other materials on request Length: 3 – 160 mm (at lengths from 60 mm only partial thread lengths 4 x d are possible) Thread diameter: 1.6 – 10 mm Special dimensions on request Batch sizes: Standard ex-stores Special screws from 30,000 pieces

The economic adjustment to small batch sizes, we meet with our turned parts for the direct assembly in plastics and die-cast products. Any thread forms such as, thread-tapping (DIN7500), thread cutting (DIN 7513-7516) or KTG for direct screw in plastics are realized cost-effectively. Advantage is the elimination of high tooling costs, since no counter-thread in the workpiece (eg threaded inserts, nuts, etc.) is required because the direct assembly takes place directly into the workpiece. Only a given tube is required in order to screw it directly. Our turned parts replace previously cold formed parts used (so-called multi-station presses) which require high output volumes in order to achieve a reasonable price parts.

With our delivery program “Screws for direct screwing” we deliver a great variety of thread rolling screws in different implementations. In doing so we realize small lot sizes and short-term delivery dates. Upon request we also introduce customer-oriented warehousing also in your company. Apart from the many advantages you can save time and money. We provide: KTG screws for thermoplastic materials: single pass thread or double pass thread (high/low); head shapes with cross or 6-star (similar Torx). Tapping screws: longitudinal slot, cross slot, cross-head-combination slot or 6-star (similar Torx). DIN 7981, 7982, 7983 or to the new ISO standards; special tip-styles, e.g. with with pressed washer. Combination screws with undetachably washers: According to DIN 6901. Self-tapping screws: According to DIN 7500. Fields of application: For thermoplastics, duroplastics, light alloys, metal compounds. Industrial consumers: Electrical industry, plastics processing industry...
