I believe many people are familiar with plastic expansion tubes and screws, because the "golden partner" appearance rate is too high.
Plastic expansion pipes, starting from the plastic age, some people use plastic columns instead of wooden rafts (wood stoppers). With the changes of the times, the walls of the buildings have become harder and firmer from the most earthy walls. The nailing has been unable to achieve a safe fastening effect, and the installation with a cork is easy to age, and the shrinkage and thermal expansion cannot achieve a long-term fastening effect. The plastic plug is installed on various substrates, which can effectively improve the defects of wood quality. At the same time, the density of the plastic is high, the shrinkage, the toughness, etc. are more accurate than the wood material, and the shape structure can also be varied, and the special shape can be specially manufactured according to the application occasion, and has a unique expansion tube. If the hardware fastening is industrial rice, then the plastic expansion tube is the industrial dish. Generally, it adopts injection molding, plastic molding, and two processing methods. The shape of the plastic expansion tube is limited, and most of the plastic expansion tubes are injection molded. Generally, PE, PA, PP three materials are used as raw materials.
They are widely used in many industries, home decoration
1. Fasten air conditioners, water heaters, range hoods, etc.
2, fixed frameless balcony windows, security doors and windows, kitchen, bathroom components, etc.;
3, ceiling screw fixed (combined with casing and cone cap).
