The Fusheng VFW oil-free, high-pressure, 100% clean air compressor series is specially designed for the PET blow molding industry. Drawing from the wealth of experience gained from long-term operations in varying conditions, the compressors are engineered to be highly efficient and reliable as they provide a stable supply of compressed air for blow molding. The series ranges from 50 to 300HP with discharge pressures ranging from 25 to 40 kg/cm2 and is accommodated for variable injection volumes. The VFW series has a built-in user-friendly interface, touch-screen panel, and PLC control system. The compressor is equipped with multiple alert systems and safety features for better overall control. Operating parameters, status, and servicing instructions are shown on the monitor to provide the user with important data concerning periodic and preventive maintenance.
The Features of Products
● PET/PP bottle forming process
1. Oven is steadily heated to provide the forming temperature evenly distributed over the bottle preforms.
2. The mold is locked onto the transmission mechanism for bottle forming.
3. Blow nozzle is inserted into the preform.
4. Air is injected into the preform to form the bottle.
5. The mold is opened.
6. The finished product is unloaded.
7. Mold stripping.
● Applications of blow molding
- The demand for (PET) bottle blowing is growing.
- VFW series compressors are designed exclusively for PET bottle blowing machines.
- The air compression process is 100% completely oil-free, allowing for the supply of oil-free, clean air.
- PET bottles and containers are recycled massively as the idea of environmental protection grows.
- The pressure of compressor is regulated between 25 and 40 kg/cm2G. making the series suitable for various industrial oil-free applications.
- The primary applications are, for example, pharmaceuticals, food and packaging, paper making, textile, petrochemicals, bacteria culturing, chemical analysis and electronics/high-tech manufacturing.
Completely Oil-Free, Clean Pressurized Air
Design criteria for the body
● Driven by the crankshaft of oil pump, no additional power needed.
● Stainless steel suction / discharge valves for high strength and long service life.
● Pistons made of aluminum alloy for effective weight reduction and dynamic balance.
● Special coating on cross-head for better wearing resistance and smoother operations in the long run.
● Single-action design for the 2nd and 3rd stages, thus reducing the number of valves needed.
● Mono-block 2nd and 3rd stage pistons, no need for 3-stage air-tight design.
● Compressor body encapsulated in a water jacket for effective cooling and increased life of parts and components.
● Piston rings made of PTFE, special formula that increases wear resistance and service life.
