Features of knurled nuts

The knurled nut adopts the embossing wheel to press the net pattern (rolled net pattern), and the middle is slotted. After milling the groove, the thread still guarantees 6H accuracy. This knurled copper nut is used in electric tools and differs from other knurled copper nuts. Further, the diamond pattern of this knurled copper nut is located in the middle of the product, and the diamond pattern knurling wheel rolls out diamond flowers along the large outer circular step surface. Knurled nut features are as follows:

1. Designs with less thickness can be tolerated.

2. It can be quickly embedded by hot melt or ultrasonic method.

3. The design of the round head guide and the positioning effect are good; it is not easy to skew.

4. The outer diameter is designed in stages, and the plastic is gradually inserted; the base material plastic is not easy to burst.

5. The design of the double diagonal pattern in the opposite direction is precisely combined with the plastic, and the twisting and pulling force is extreme

Shorter molding cycles, automatic injection molding without insertion of metal parts

● No risk of damage to the injection mold from falling out metal parts

● No stress cracks resulting from hardly controllable shrinkage around the metal part

● Advantages over self-tapping screws since the joint can be detached as often as required without damaging the thread

● Safe, stress-free anchorage with high pull-out and torsion values

● Reduction of manufacturing costs for the plastic parts and increased quality of your products

● Low-maintenance machines in combination with innovative control concepts (service expenses reduced to a minimum)

Under the name of offers thread inserts nuts and the respective assembly systems for the after-molding technology. The thread inserts are specially designed for after-molding insertion. The result is wear-free, high-strength threads in your high-quality plastic components. They are suited for installation in moldings of thermoset, thermoplastic, or reaction resin materials (filled or foamed). There are various installation methods:

● Thermal installation – heated element welding, electromagnetic resistance welding

● Ultrasonic welding

● Expansion anchoring

● Self-tapping insertion

● Pressing

To apply the most efficient installation method in every case, we offer the following:

● Manual installation tools

● Semi-automatic tools

● Automatic machines: from multiple installations for large-scale production to the freely programmable CNC-controlled installation machine for frequently varying components. Feel free to contact us for the development and production of customized thread inserts and installation devices.
