PPR pipe is one of the most widely used plastic pipes in the world. Because of its excellent hygienic performance, PPR pipe can meet extremely high hygiene and environmental protection requirements from production and use to waste recycling. The advantages of thermal insulation, energy saving, long service life and economy are often used in domestic applications and buildings, including:

1. Cold and hot water systems of buildings, including central heating systems;

2. Heating systems in buildings, including floors, siding and radiant heating systems;

3. Direct drinking pure water supply system;

4. Central (centralized) air conditioning system;

5. Industrial pipeline systems such as transporting or discharging chemical media.

6. Piping systems such as air passages for cylinder transmission.


What are the components of the pipe fitting injection molding production line system?

1. One-stop supply of RRP pipe injection equipment, including pipe injection machines, pipe molds, intelligent injection molding systems, and auxiliary equipment including automatic feeders, dryers, chillers, mixers, manipulators, conveyor belts, etc.

2. The production line equipment configuration plan is optimized. According to your annual output requirements and the characteristics of plastic parts raw materials, we recommend suitable matching plans for machines and auxiliary equipment. Of course, this is based on your requirements and budget.

3. Door-to-door installation of equipment, while providing production line operation stability testing and training for possible solutions to injection molding problems.

4. 24 hours online to solve your problems and timely on-site service

5. Other contents of the production line system include: product optimization design, injection molding workshop layout design, management and operation personnel training, etc.


  • 1. Super-efficient and energy-saving. Under the same working condition, compared with traditional hydraulic injection molding machine, it can achieve 20%-80% energy saving rate
  • 2. The molding is very stable. Servo drive system, closed-loop control, compared with the traditional hydraulic injection molding machine, the molding repeatability is greatly improved
  • 3. Ultra-sensitive responsiveness. The sensitive servo drive system responds quickly, and the quick start time only takes 0.5s
  • 4. Super performance and environmental protection. The whole machine runs with low noise, and the low-speed operation is quieter
  • 5. Reliable pressure holding performance. Compared with the traditional hydraulic injection molding machine, the pressure holding time adjustment range is wider and the pressure holding performance is more stable
  • 6. Constant oil temperature. The servo motor proportionally outputs hydraulic oil to avoid excess heat generation, the temperature rises slowly, and the hydraulic oil does not even need to be cooled, thus achieving substantial water saving.
