Plastic injection molding (injection molding) for the plastic head of the pipe sealing parts

The plastic bulkhead is processed using plastic as the raw material. As a raw material, plastic is mainly composed of synthetic resin. Plastic pipe caps, pipe plugs, plastic flange covers, and wire protection caps can be molded into a certain shape under certain temperature and pressure conditions, and the shape remains unchanged at room temperature. Because plastic itself has the following characteristics:
1. Wide distribution of mechanical strength and high specific strength: from the point of view of mechanical properties such as hardness, tensile strength, elongation and impact strength of plastic, it has a wide range of distribution and a wide range of use options.
2. Good chemical stability Most plastics have good corrosion resistance to acid, alkali and other chemicals.
3. With reliable electrical insulation performance, ordinary plastic is a poor conductor of electricity, with high surface resistance and volume resistance, which can reach 109-1018 ohms in numerical terms.
4. Bad conductor of heat: It has the function of noise elimination and shock absorption. Generally speaking, the thermal conductivity of plastic is relatively low, equivalent to 1/75-1/225 of steel. The micropores of foam plastic contain gas, and its heat insulation, sound insulation and shock resistance are better.
5. Light weight, relative density between 0.90 and 2.2.
The plastic bulkhead, developed with the above characteristics, is widely used in fields such as automobiles, building materials, IT, and hardware, playing an increasingly important role in people's production and life. Plastic pipe caps, pipe mouth plugs, plastic flange covers, wire protectors, plastic plugs, plastic plugs, steel pipe protectors, steel pipe caps, steel pipe plugs, plastic pipe plugs, plastic pipe plugs, pipe mouth dust plugs, plastic valve covers.
