PP Hollow Construction Formwork Extrusion Line
Our PP Hollow Building Template Extrusion Line is specially developed for producing high-performance plastic construction formwork. Compared with traditional wooden formwork and plywood, PP hollow building templates have obvious advantages of water resistance, no deformation, no mildew, long service life and recyclable use, which greatly reduces the construction cost for customers.
The complete production line includes screw extruder, mold, vacuum calibration unit, traction machine, cutting system and stacking device. It realizes fully automatic continuous production with stable running performance and high finished product qualification rate.
Product Features
  • High efficiency & stable performance: Optimized screw and barrel design ensures uniform plasticization, stable extrusion speed and large output.
  • Wide application: The produced PP hollow boards are widely used in building construction, highway bridge, tunnel engineering, municipal engineering and other fields.
  • Energy saving & low loss: Equipped with advanced frequency conversion control system, effectively reducing power consumption and production failure rate.
  • Durable finished products: The PP hollow template features high toughness, strong compression resistance, no crack, reusable for more than 50 times.
  • Environmentally friendly: Plastic formwork can be recycled and reprocessed, no construction waste pollution, meeting green building requirements.
  • Customizable size: The production line can be adjusted to produce different thickness, width and hollow structure boards according to customer demands.
Technical Advantages
This extrusion line adopts professional plastic forming technology, with precise thickness control and smooth board surface. The automatic traction and fixed-length cutting system ensures consistent product size. The whole production process is simple to operate, labor-saving and suitable for mass industrial production.
Application Scope
Ideal for various concrete pouring projects, such as residential buildings, commercial buildings, viaducts, tunnels, dams and other construction fields. It is the best replacement for traditional wood formwork and steel formwork.
