Household appliances are ubiquitous in modern family life, from air conditioners, refrigerators, washing machines to microwave ovens, water heaters and kitchen appliances. Compared with general mechanical structure, household appliances often face complex working conditions such as high frequency vibration, thermal cycle, humidity change and long-time continuous operation, which puts forward higher requirements on screw material, anti-vibration performance, corrosion resistance and precision machining.
Core performance requirements of household appliance fasteners
In typical applications of household appliances, screws are not only structural connectors, but also key components to ensure long-term reliable operation of the overall system. Therefore, high performance screws shall have the following characteristics:
Anti-vibration and anti-loose design: household appliances will produce periodic vibration during operation, and high-performance anti-loose screws can reduce the risk of loosening.
Corrosion resistance and moisture and heat resistance: stainless steel or screws with Dacromet and galvanized surface shall be selected especially for the parts easy to be affected by humidity, such as air conditioners and refrigerators.
High strength and clamping force: ensure stable connection under thermal cycling, mechanical vibration and frequent switching conditions.
Precision dimensions and consistency: precision screws improve assembly efficiency and quality consistency in large-scale assembly production.
Screw application scenarios in household appliances
Application of screws for air conditioning system
In the air conditioning system, screws are mainly used to fix the compressor, rack, electronic control module and condenser, etc. They shall have high strength, anti-loose and anti-corrosion performance to deal with long-term vibration, thermal cycle and hot and humid environment and ensure the stable operation of the whole machine.
Washer Screw Application
The washing machine has strong vibration and frequent rotation speed change during operation. The screws are widely used in the fixing of roller drive, structural frame and control system. It requires high strength, high precision and corrosion resistance to reduce noise and improve the durability of the structure.
REFRIGERATOR AND REFRIGERATOR SCREW APPLICATION
In refrigerators and refrigerators, screws are used to fix shells, shelves, compressors and pipelines. Corrosion resistance, low temperature resistance and stable clamping force shall be taken into consideration to adapt to changes in condensate and temperature difference and ensure long-term safe operation of refrigeration system.
YH FASTENER's Advantages in Household Appliance Application
Yuh FASTENER has been engaged in fastener manufacturing industry for many years, focusing on the development and production of high-performance household screws. With mature material engineering design, strict heat treatment process, CNC precision machining and automatic full inspection system, it can provide stable, consistent and highly reliable fasteners for household appliance manufacturing.
We can provide a variety of screws for structural connection of household appliances, including:
Locking screw: applicable to installation of air conditioning compressor and connection of electric control panel;
High-strength precision screw: used to fix the washing machine drive and frame;
Corrosion-resistant stainless steel screw: applicable to hot and humid environment such as refrigerator and refrigerator;
Surface treatment screws (galvanized, dacromet, etc.): improve corrosion resistance and assembly stability;
In addition to conventional screw fixing, spring plugs are widely used in household appliances for positioning and limiting functional parts, such as movable panels, adjustment mechanisms, removable components and maintenance structures. Through the internal spring and ball structure, the positioning ball realizes repeated positioning, fast assembly and stable limit. In the air conditioning outlet adjustment, washing machine function module positioning and the maintainable structure inside the appliance, it can effectively improve the assembly efficiency and use reliability, and reduce the structural wear caused by repeated assembly and disassembly.
With stable and reliable screw and positioning solutions, YH FASTENER constantly helps household appliance brands to improve structural safety, reduce after-sales failure risks, and bring longer service life and higher overall value to products. Please contact us to obtain fastener solutions suitable for your household appliances.
