Any manufacturing process requires a professional approach, from planning procurement of materials to the mechanism of shipment of finished products.
The production of facade structures is no exception. At the first stage of the organization, it is necessary to make the right choice of equipment for the production of plastic windows.
Main steps
First you need to determine the planned volume of products. For this, an analysis of the future sales market is done and, based on its results, the optimal and maximum number of windows is calculated. Then you need to make a minimum set of equipment. Along with this, components are selected for the production of plastic windows: a profile system, furniture sets, types of double-glazed windows.
Equipment necessary for the release of structures:
- Cutting machine. CNC single-head or two-headed saw.
- Copy machine. Serves for the manufacture of technological holes in the profile.
- Welding machine for connecting corner structural elements.
- Hardware installation table. It can also be a place of installation of double-glazed windows.
For each of the stages, equipment with the same performance is selected. In fact, this is difficult to achieve, so sometimes one worker performs several operations. For a detailed analysis, it is necessary to consider the stages more carefully.
Cutting and welding
Before choosing, you must carefully familiarize yourself with all the intricacies of the process. Production begins with cutting a PVC profile. For this, a special cutting machine or a simple circular saw is purchased. In the latter case, the speed of the operation will be minimal.
The correct choice of equipment for the production of plastic windows during this operation will determine the shift volume of products. Before cutting, the temperature of the profile must be at least + 18 ° C. To reduce% of waste, a cut calculation is performed for each batch of workpieces. Upon completion of this process, they start welding structures.
Previously, a reinforcing steel profile is installed in each workpiece and technological holes are made using a copying machine. Steel profile cutting is carried out using a special circular saw. To optimize the time it takes to move the workpieces from one operation to another, it is recommended to place the saw in the immediate vicinity of the copy machine.
The profiles are connected to each other by temperature diffusion. The end surface of the workpiece is heated to the optimum value - about 240 ° C. Then, using hydraulic clamps, parts of the future window are interconnected. Stripping the weld provides a good appearance of the product. This can be done manually (narrow chisel) or on a special machine.
Hardware Installation
The welded structure is moved to the fitting table. Usually it is equipped with pneumatic screwdrivers that operate from a compressor unit. Materials for the production of plastic windows must include fittings. They are necessary to ensure the functioning of the sash structures.
Along with European trademarks, preference has recently been given to products of Turkish and domestic production.When choosing, you need to know about the possibility of providing from the supplier of furniture templates for attaching elements. They will significantly speed up the assembly process and avoid installation errors.
Glazing
The most important stage of the entire production process. It will require a table or a special vertical stand. It is a frame structure on which a window frame is mounted using hydraulic clamps. This is not a mandatory equipment for the production of windows, and at the stage of establishing a business, you can do without it.
Fastening of double-glazed windows is carried out using PVC glazing beads. They are pre-cut at an angle of 45 °, and then installed in the mounting grooves of the profile. Double-glazed windows can be ordered from contractors, providing them with information about the required dimensions and configuration of the product.
At the same time, the operability of the fittings is checked, the quality of the welding of the corners is checked. The main regulatory documents in this case are SNiPs and technical documentation of component suppliers about possible errors.
For a general idea of the specifics of manufacturing PVC structures, it is recommended to visit several assembly shops. It is best to choose enterprises with equipment of various capacities. On the example of the construction of the production process, you can know in advance the subtleties and nuances, which will further facilitate the process of organizing your own line.
