Why H-shaped Spring Strip?

The patented universal bracketless windshield wiper blades are constructed focusing on H-shaped spring strip; it is an elite invention on multiple wiping edges for lofty wipe quality. The old car wiper blades only concentrate on few points when wiping whereas H-shaped bracketless car wiper blades are multiple pressure points spread evenly on the blade. Accordingly, the bracketless windshield wiper blades are designed without metal or plastic brackets, joints or hinges, offering design and performance improvements over conventional wiper blades and the performance of frameless windscreen wiper blades are more efficient.

The bracketless windshield wiper beside having H-shaped spring strip; it also includes two internal tension strips for improving moisture removal. Dual-wiper frames and EPDM made wiper strips' temperature tolerance is between -20 to +70°C which means they are UV, ozone resistance for various weather conditions. High quality spring steel is applied to ensure its long life cycles. Cap-shaped elongated body has a base end opening and receives at least one holding lever and one backing plate wherein the front surface wall has a tilted outer surface that is tilted relative to the wiping surface to form a fin. There are four (A/B/C/D) different types of POM constructed adapters that make the windshield wipers suitable for various automobiles. Easy and simple wiper strip replacement which is eco-friendly and saves money.

Is Bracketless Windshield Wiper Really Better?

Universal bracketless windshield wipers for automotives have wiper arms, which are constructed of a fastening part, tightened to a drive shaft; a hinge part connected to it through a toggle point; and a wiper rod firmly attaching the hinge part. A windshield wiper blade with a strip is pivotally attached to the wiper arm and guided over a windshield; the hinge part and the wiper blade are embodied such that the wiper strip can adapt to an arc of the motor car window. A necessary contact pressure of the wiper strip on the automotive windshield is achieved with at least one tension spring, which braces the fastening part and the hinge part jointly with the wiper rod, via the toggle joint. The goal of the invented wiper blade is to provide a universal connection device which a same wiper blade can be mounted onto various types of wiper arms. By eliminating the brackets and joints in a bracketless design, TOP AUTO has increased the wiper blades' ability to conform to the curvature of each windshield, which applies uniform pressure along the entire length of the wiping element and results in a cleaner, quieter wipe each time.

Bracketless Windshield Wiper Supplier

TOP AUTO's automotive OEM wiper blades were tested using various equipments for their corrosion, pulling, temperature and durability capabilities. For salt spray testing, it is an advanced corrosion test that assesses the durability of coatings on super structures, fastener/clip integrity, paint and rubber reliability. 1,500,000 times wiping test helps defining the windshield wiper blades' wipe quality and super structure as well as the durability for times of wiping. The frameless wiper blade is also tested under difficult environment between temperatures -20 to +70°C for its persistence. When OEM wiper blades sitting on a windshield for an extended period of time, windshield wiper blades can form a permanent set, therefore, windshield wipers must have a low permanent set to guarantee appropriate blade flipping over the life of the blade. TOP AUTO's 100% natural rubber (EPDM) made windshield wipers are to prevent ozone damage and hardening to the rubber.
