When designing doors and windows, it is considered from the beauty of the whole house and the area where it is resistant to wind pressure, water tightness, air tightness, heat preservation, heat insulation and sound insulation (now Beijing, Guangdong, etc.) There are regional regulations that have required the corresponding building doors and windows to meet the corresponding requirements).
Imagine the physical properties (wind resistance, water tightness, air tightness, sound insulation, heat preservation, heat insulation, etc.) and mechanical properties (opening and closing force, repeated opening and closing) of doors and windows, which are related to doors and windows. The hardware accessories are irrelevant. The hardware accessories are the components that are responsible for connecting the frame of the door and window to the fan. Without it, the door and window will only become a dead fan, and the meaning of the door and window will be lost.
System selection comprehensive considerations?
Especially the design and selection of the profile size, it can be said that there is no good profile to be the cornerstone, and what kind of hardware can not be used to make good doors and windows. For the profile and hardware to be comprehensive considerations, be careful not to select the profile, then select the hardware, this situation sometimes leads to the lack of matching hardware due to the standard of the profile.
Now most real estate developers will consider the combination of profiles and hardware, and then give them a choice. The choice of accessories should consider its versatility and rationality, while considering the processability and material quality of the parts production.
Of course, there are also matching options. This situation will definitely bring difficulties to hardware matching.
At present, the profile of profiles of domestic aluminum alloy interior doors and windows is relatively standardized, and more than 80% of them are European standard groove profiles, which are simpler to select. The cross-section of the profiled windows and doors is quite complicated. The frame fans have grooves, the frame fans have no grooves, the frame has no grooves, and the fan-shaped profiles are different. The groove size of the grooved profiles also changes.
The profiles of aluminum alloy sliding doors and windows are more diverse, and the dimensions of profiles such as hook, light, edge, bottom, and slide are different for each profile manufacturer.
As a manufacturer of hardware accessories, according to the characteristics of the profile, it should be selected according to the principle of not destroying the structure of the profile and making less punching, convenient installation and adjustment, and ensuring the performance requirements of doors and windows.
It is necessary to meet the rationality of the selection of door and window hardware accessories, meet the needs of customers, and control the production cost of the enterprise. Promote the reduction of differentiated production, reduce the replacement of tooling fixtures, reduce the inventory backlog and waste of materials, as well as the procurement of raw materials and semi-finished products, and how to improve the productivity of workers to reduce the production costs of enterprises.
It is also convenient for post-maintenance maintenance work. Taking standardized products, the company implements the Industry 4.0 model, which can improve production efficiency and ensure quality. You can do some proper inventory planning, and the business can also be sold now, achieving a win-win situation for both parties.
Three major components of hardware accessories?
Door and window hardware is divided according to function. A door and window hardware has three major components: operating parts, locking parts, and connecting load-bearing parts. Reduce the production cost of hardware accessories, take standardized products, the following specific analysis:
First, the operating parts (handle)
At present, the profile standards in the industry are developed in accordance with the European standard. In order to improve energy-saving efficiency, aluminum sections are made of multi-cavity broken bridge insulation profiles. China's aluminum materials are rich and diverse, which brings richness to people's windows. The variety and choices that have brought manufacturers a wide range of hardware accessories.
The operation component handle is used to open the doors and windows every day. There are many components and the internal structure of each enterprise is different. The products to be finished must have standard raw materials and mature processing technology, and reasonable quality inspection. And the installation should also be in place, the correct fixing method, if it is not firm and the surface is damaged, the opening and closing swaying gap is large, the hand feel is poor, the operator can perceive the quality of the door and window hardware accessories.
The mounting screws are loose and loose, the handle is loose, and even the fixed feet are broken, which will affect the service life of the doors and windows. According to industry standards, the service life of the hardware after anti-corrosion and anti-rust treatment is 10 years, which is enough to meet the use of normal building doors and windows. Good hardware should look thick, and the surface gloss should be good, the protective layer should be dense, and there is no scratching. The most important point is that the opening should be flexible.
Second, the locking component
The locking components mainly include transmission parts such as a lock point, a lock, a transmission, and a corner. The use of these accessories plays a vital role in the physical properties of the doors and windows (wind resistance, water tightness, air tightness, sound insulation, heat preservation, heat insulation, etc.), and requires anti-theft function when locked. .
This requires that the hardware parts should be firmly embedded in the profile. Only when the combination with the profile is firm, the anti-theft function can be realized. Therefore, the European standard groove profile should be preferred, and the five-party accessories are standardized, no special configuration is required, and can be selected at any time. And the quality is excellent.
It can meet the principle of not destroying the structure of the profile and less punching, convenient installation and adjustment, and ensuring the performance requirements of doors and windows.
Instead of the unslotted profile, the hardware is fixed by screws. Imagine only a 1.4mm thick aluminum profile, the screw is 5mm large, and the anti-theft capability of the slotless profile that can be fixed by screws is much smaller than that of the European standard groove profile. Anti-theft capabilities.
Third, the frame, the fan connection tribute parts
Connecting the load-bearing parts The main ginger has hinges (hinge), sliding supports, and pulleys. The selection of this component is particularly important, related to the performance, safety, and life of the door and window function.
In terms of functionality, hinges (hinge) are important components for the rotation and load-bearing of doors and windows. They are mainly used for inner casement and flat door opening. Their firmness and anti-theft performance are the same as lock components. European standard groove hardware accessories. It is better to use the stainless steel clamp to bite the hinge of the European groove than the safety of the screw.
The sliding support is applied to the outer casement window and the curtain wall outer suspension window. Because the window is opened outwards, it is necessary to consider the bearing requirements such as the height, width and weight of the fan, and select the sliding support of the corresponding load-bearing level.
Especially in the load-bearing performance side, it is important to consider. Sometimes, in order to improve the light transmittance and ventilation of building doors and windows, the designer enlarges the size of doors and windows, neglects the safety of doors and windows, increases the number of fixed windows, increases the number of windows, and reduces the number of windows. The window size reduces the safety of the operator, otherwise the consequences will be unimaginable in the event of a safety problem.
At the same time of high attention and attention, it is the hardware that is constantly improving the changes and improvements of the function of doors and windows. The change of concept, under the traditional competition conditions, hardware companies rely on internal advantages, such as product quality, product brand influence and so on.
The current market competition is not only through its own internal advantages, but also through the promotion of its own resources and market propaganda. Forming a combination of internal and external strengths, focusing on the quality of hardware products, but also on the improvement of hardware brands, focusing on the improvement of service is very important.
