Plastic expansion tube source:
Plastic expansion tubes have been used since the era of plastic to replace wooden dowels (wooden plugs). As times change, the walls of buildings have become harder and more solid, and the original iron nails can no longer achieve a secure fastening effect. Using wooden plugs for installation can easily deteriorate, and the effects of thermal expansion and contraction cannot achieve long-lasting fastening effects. However, plastic plugs can effectively improve the shortcomings of wood materials in various substrate installations. At the same time, plastic has a high density, better shrinkage, and toughness than wood materials, and can be customized to meet specific applications. It can also be manufactured in various shapes, making it a unique expansion tube with unique characteristics. If we say that metal fasteners are the rice of industry, then plastic expansion tubes are the dishes.
Plastic expansion tube molding:
Generally, injection molding and extrusion molding are used, with extrusion molding having limited styles due to its shape, and most plastic expansion tubes are made by injection molding. Generally, PE, PA, and PP are used as the raw materials.
Plastic expansion tubes, also known as plastic expansion screws, have various names depending on the region. Commonly, they are called expansion tubes in the north and plastic expansion beads or expansion glue beads in the south, especially in Guangdong and surrounding areas.
English name: wall plug, Expansion pipe. To securely fasten a plastic expansion pipe, screws are needed. The correct pairing for plastic expansion tubes is with a coarse-thread self-tapping screw. Why recommend using coarse-thread screws is because a fast-thread self-tapping screw is easy to cut into the expansion tube body, and it may even cut the expansion tube, not achieving the best expansion effect.
Plastic expansion tubes can be used with self-tapping screws, such as external hexagonal self-tapping screws, cross-headed self-tapping screws, pan-headed self-tapping screws, external hexagonal self-tapping screws, and large flat-headed self-tapping screws, with materials being unlimited. They are applied in bathroom products and should be selected for stainless steel self-tapping screws in humid areas.
HuanJie plastic expansion tube size:
Diameters M5, M6, M7, M8, M10, M12, M14, lengths ranging from 20mm to 160mm or even over 200mm. Common sizes include M6*30mm, M8*40mm, M10*50mm, M12*60mm.
Expansion tube classification
Huanjie plastic expansion tubes are divided into civilian plastic expansion tubes and industrial plastic expansion tubes.
Nylon expansion tubes are used for general home improvement, matching, and connecting small objects. Industrial plastic expansion tubes come in various shapes and are used to fix the base material (such as thin boards, hollow walls, ceilings, and gypsum boards). There are also larger ones that are used for heavier objects to ensure stability, such as supports and machinery.
