- Shorter moulding cycles and automatic injection moulding without metal part insertion.
- Reduced risk of damage from falling metal parts.
- Stress-free anchorage with high pull-out and torsion values.
- Cost reduction and increased product quality.
- Low-maintenance machines with innovative control concepts.
A selection matrix indicates the suitability of various thread inserts for different materials and installation efforts. HITSERT® 2 and SONICSERT® are suitable for thermoplastics, while EXPANSIONSERT 1 and 2 are for thermosets.
- Thermal Installation: Includes HITSERT® and SONICSERT® variants.
- Self-tapping Insertion: Includes QUICKSERT® variants.
- Expansion Anchoring: Includes EXPANSIONSERT and SPREDSERT® variants.
Detailed technical data for each variant includes material specifications, installation principles, and advantages. HITSERT® 2 is ideal for thermoplastic components, offering high pull-out values and efficient installation.
AMTEC® thread inserts are versatile and efficient in various industrial contexts, including automotive, medical engineering, consumer electronics, and mechanical engineering.
Specifications for SONICSERT® and QUICKSERT® include pull-out and torque values for materials like ABS, PC, PA, and PE/PP, with guideline values suggesting application-specific tests.
Thread inserts are made from brass (CuZn38Pb2 or CuZn39Pb3) and comply with EU standards, with steel as an option. Design features include a large flange for reduced surface pressure and options for nickel plating to prevent stress cracks.
Methods include ultrasonic welding, electromagnetic resistance welding (ERW), and heated element welding (HEW), each described for embedding thread inserts in thermoplastic components.
SONICSERT® and QUICKSERT® offer high pull-out values, low-stress anchoring, and are suitable for thermoplastic components, designed for ultrasonic installation with benefits like screw-locking and installation from both sides.
Various thermal installation machines and ultrasonic welding machines are suitable for embedding thread inserts in applications like automotive and electronics.
For fibre-reinforced plastics, assume strengths of non-reinforced materials. For plastics prone to stress cracks, surface treatments for thread inserts are advised.
The company offers customized solutions and encourages contact for additional strength values or specific requirements.
Technical specifications and guidelines for QUICKSERT® thread inserts, designed for self-tapping and self-forming insertion into various materials, include data on pull-out strengths, driving torques, and recommended mounting holes.
Mechanical properties such as pull-out values and driving torque values for different materials and thread sizes (M3 to M8) are specified, with guideline values for laboratory tests.
Installation procedures for QUICKSERT® Hex and Plus variants include specific installation tools and machines, emphasizing application-specific installation tests for reliability.
Technical data for QUICKSERT® inserts includes material composition (brass or steel), dimensions, and item codes, with recommended mounting hole diameters for various materials.
Application-specific installation tests are recommended, especially for fiber-reinforced plastics, to ensure appropriate strength values. Use strengths of non-reinforced materials as a safety measure.
Various installation tools are described, including semi-automatic and manual options, with item codes for different tool sizes, highlighting advantages like quick and safe positioning and reduced operator fatigue.
The QUICKSERT® system offers high-strength and torsion-resistant threads, efficient installation, and options for thermoplastics and thermosets, with special versions for improved reverse locking.
Technical specifications and installation procedures for SPREDSERT® and QUICKSERT® expansion anchoring systems, designed for use in reactive resins, thermoplastics, and thermoset components, offer advantages like wear resistance, quick installation, and high-strength threads.
Multiple thread insert types with specific dimensions and material compositions, primarily brass CuZn38Pb2 and CuZn39Pb3, are listed, with detailed tables for different thread sizes (M 2 to M 8).
The installation process involves pressing the thread insert into a mounting hole, where it expands to lock into place, with increased tightening torque by 10% for additional expansion force. Manual and semi-automatic tools are outlined, with specific item codes.
Torque and pull-out values for different materials (ABS, PC, PA, PE/PP) indicate the strength and reliability of the thread inserts under various conditions, with application-specific installation tests suggested for optimal performance.
Thread inserts are applicable across diverse industries, including automotive, medical engineering, consumer electronics, and mechanical engineering, used for fastening components like engine covers, decor strips, and electronic assemblies.
For plastics susceptible to stress cracks, additional surface treatments like nickel plating are recommended. Brass inserts are suitable for plastics, with specific testing advised for stress-prone materials.
