Today’s business project is about PVC profiles, which are the main product type for metal-plastic frames.
General information about the project:
- Production capacity: 300-350kg/hour
- Required working space: 30m x 10m building
- Required manpower: 5 people (for 1 shift)
- Energy consumption: 80KW/hour
- Voltage: 380V 50Hz
Brief information about the history of PVC profiles:
Plastic frames are so common that today it is an indispensable attribute of any modern design. But 50 years ago, no one knew what it was.
The history of the appearance of polyvinyl chloride (PVC) began in 1835. It was in this year that the American chemist Regnald managed to invent polyvinyl chloride, which later became the material from which plastic windows began to be produced.
The first industrial production of plastic windows took place in the USA in the 50s. Later, Europe saw a great prospect and began to develop and apply these technologies. And soon, in 1952, German developers were the first to create and patent the construction of PVC windows.
PVC frames began to appear in our country in the mid-90s, at first such profiles were imported from abroad, and due to the high price of frames, not everyone could afford to install such frames at that time. By the 2000s, the production of PVC frames in our country and market competition made PVC frames an acceptable building material for everyone.
It should be noted here that PVC frames differ from traditional wooden frames in terms of their resistance to external impacts and weather changes, fire resistance, high energy efficiency, beautiful design and noise reduction. It excels with the qualities of impermeability.
In addition, the number of chambers of PVC profiles is important in maintaining a moderate room temperature.
Now let’s turn to the production process. The production line of PVC profiles for Rom consists of 3 major parts. These are:
1. PVC profile extrusion line
2. Part of preparing the mixture
3. Lamination line

The PVC profile production line consists of an extruder, a film, a calibration table, a weighing device, a profile saw and mechanisms for marking, laying and applying a protective film to the finished product (profile).
Production is carried out by extrusion. Extrusion is a continuous process of extruding a preheated mass of polymer through shaped holes in a mold. The extruder ensures the melting of the mixture and the continuous supply of the solution under a certain pressure.

The calibrator gives the desired shape to the mass of the solution. The puller pulls the profile out of the calibrator at a stable speed, providing optimum force.
1.4 Cutting part

2. Special molds
“AFEX-GROUP” offers you 8 types of special molds. With the help of these molds, you can produce PVC profiles of any shape for frames.
