What is insert nut?
It is a nut used for molding plastics such as synthetic resin, and it is used by being embedded in plastic material.
Because resins and plastics are lower in strength than metal, joining the resins together makes it easier for the joints to come off.
Embed the insert nut so that it will not come off.
There are two methods of embedding in plastic material: "Insert at the time of molding" to be buried at the time of plastic molding and "Insert after molding" to be embedded after molding. Various sizes and types of nuts can be used depending on the application, so the optimum insert can be used with the optimum embedding method.
Type of synthetic resin
Among substances made of polymer compounds, they were manufactured for use as molded products or thin films, and there are roughly two types, "thermoplastic resin" and "thermosetting resin".
It becomes soft when adding heat and hardens when it cools, and once softened it can become soft again by applying heat.
It is excellent in toughness, it can be molded in a short time, and the cost is low, so productivity is high.
Since it can be molded again by heating, it is easy to recycle defective products etc.
Therefore, thermoplastic resin is the majority of synthetic resin.
It becomes hard when applying heat, and there is a property that it does not become soft even if applying heat again.
As a characteristic of molecular bonding, it is stable, strong and resistant to heat.
It is a silicone rubber dish, for example.
Because it can withstand high heat, it can withstand ovens and ranges.
It does not stick to food and range, thermosetting resin is excellent in heat resistance.
However, compared with thermoplastic resin, there is a high possibility of cracking and crushing if dropping it weakly to impact.
There is also a property that materials can not be reused.
Types of plastic materials
Polyethylene (PE), polypropylene (PP), polytetra (PTFE), liquid crystal polymer, polyphenylene sulfide (PPS) and so on.
There are vinyl chloride (PVC), polystyrene, ABS resin, methacrylic resin, polyamide (nylon resin), and others.
There are various features depending on the type and the heat resistant temperature is various.
Crystallinity is excellent in heat resistance, and amorphousness is excellent in transparency.
Thermoplastic resin and thermosetting resin have different characteristics.
Depending on the characteristics and strength of the molded product, it is necessary to select plastic materials and shapes.
First of all, it is good to ask the company that manufactures the insert nut.
