Heating Press - In 6H Plastic Threaded Inserts With Good Performance Of Torsion And Tension
Introduction
In some design occasions, it is necessary to embed pre-formed parts (usually metal products) in injection molded products. For example, when molding certain injection products, in order to increase the mechanical strength and service life of the injection products, the frequently used screw holes, screws, etc. are made of metal.
Cold pressed nuts refer to directly pressed into plastic without heating (at room temperature). This concept is relative to hot pressed nuts, and does not refer to nuts that are pressed into plastic "after cooling".
There is no unified national standard or industry standard for cold-pressed nuts. According to some commonly used styles of users and their own manufacturing habits, these standards (or styles) can be organized for users as a reference when designing products and selecting specifications.
Why not use hot melt, but need the classification style of cold pressed nuts?
We know that some thermosetting plastics (such as phenolic plastics, epoxy plastics, amino plastics, unsaturated polyesters, alkyd plastics, etc.) use thermosetting resins as the main component, combined with various necessary additives to form plastics through a cross-linking and curing process. Products, this kind of material cannot be hot melted or softened again once it is solidified. Obviously, hot melt (hot, ultrasonic, etc.) nuts are no longer suitable for this plastic. In this scenario, it is suitable for cold pressed nuts.
Material
Knurled
Diamond flower: easy knurling curve, shallow knurling, massage control embedding process, not suitable for hot-melt process, good performance in process.
Twill flower: The knurling area and depth of the villain are easy to control, and it has a self-directed function when implanted, and the overall performance of torsion and tension is good.
The knurling standard of Lijingfan hardware implements the DIN82 standard.
The torsion force of the knurling is related to the traction angle: with the angle of the rising value, the tensile force becomes larger and larger; the heating value increases slightly
