Track/ Lower Upper Control Arms(Wishbone Arm) are one of the most common vehicle parts, and you will find it in almost every automobile on the road with both Luxury Car such as Maserati Tesla BMW Mini Mercedes Benz Audi Infiniti Lincoln Land Rover Jaguar Cadillac Alfa Romeo Volvo Lexus and Generally Passager Car such as Toyota Volkswagen Nissan Honda Mazda Hyundai Kia Peugeot Citroen Ford GMC Jeep Pontiac Mercury Mitsubishi Dodge Chrysler GM Chevrolet Daewoo Renault Isuzu Suzuki Skoda...BENGBU SMK AUTO PARTS CO.,LTD  We Focus on Quality Only.

Control arms feature three main parts: bushings and sleeves, main body, and ball joint. Control arm bushings help to reduce friction and vibrations while the control arm ball joint forms the pivot at the steering knuckle or wheel assembly. The main body is the control arm link that connects the component to either end. It can be stamped steel, cast iron, or aluminum.

Control Arm Material And Assembly Types:

Generally, A Control Arm can made by Stamped Steel(Stamping), Aluminum, Cast Steel(Casting Iron).

1. Have an independent R&D team from mold design-mold R & D and manufacturing-rough forging-heat treatment-surface treatment-machining-bushing-assembly-finished product assembly, all completed in our own factory to ensure the speed of new product development and major The S4 store is selling new cars simultaneously, covering 98% of domestic luxury cars.

2. Insist on using the original factory parts samples to develop the mold one-to-one to ensure the same size as the original factory installed car.

3. After the development of the new product is completed, the performance of all loading experiments is tested to ensure that the loading size is correct before mass production and launching on the market.

4. Insist on the use of high-strength aluminum alloy material for the control of raw materials. Mark: 6082 aluminum forgings (T6 heat treatment German process). Shanghai Baosteel high-strength iron plate material: QSTE460 QSTE500 sheet strength is the best and the lowest carbon content is to ensure high product strength/ Good toughness.

5. Forging: It has independent aluminum forging and iron forging lines (without purchasing common mold blanks) and uses 1600 tons of high-precision forging lines to make blanks using industry-leading roll forging technology to ensure consistent product contours and stable quality.

6. Ball seat: Japan POM (main machine matching level standard), one mold ensures that the accuracy of each ball seat is consistent, and it has the function of filling the gap. Excellent wear resistance and service life up to 1 million times.

7. Lubricating grease: Japan AUTOLEXC (host supporting level standard), high temperature resistance of 120°, low temperature resistance of minus 45°, enough to cope with various extreme weather conditions.

8. Rubber sleeve: All dust cover uses neoprene (CR), the bushing uses natural rubber (NR), and insists on independent production. The original rubber is all made by Hyundai Kia's main engine supplier (standards from the main engine factory) to ensure product stability Play a better buffer effect.

9. Processing equipment: use Japanese OTC/Panasonic robots to weld Japanese brand high-precision 5-axis machining center (the rough processing is completed at one time), and Taiwan imported high-precision ball pin mirror machine to ensure the stability of mass production.

10. Spend funds to build a high-end surface treatment workshop with fully automatic assembly line operations and all use German imported equipment and raw materials. Aluminum arms: sand polishing, fine polishing, closed passivation surface treatment, iron swing arm: plastic spray assembly line operations are completed in the factory to avoid product collisions To ensure that the product has the best appearance and presentation.

11. Product testing has the leading independent laboratory of domestic factories and insists on: product salt spray test reaches 720 hours; ball pin pull-off force ≥ 40 kN; bush pull force ≥ 15 kN; bush fatigue test 800,000 times No cracks; the ball joint has reached 800,000 times of fatigue test without loosening; the dust cover has no cracks after 72 hours of ozone aging; the elongation rate of the original rubber is ≥500%; the hardness change of the original rubber does not exceed 5 degrees at a high temperature of 100°70 hours. 30%; the original rubber will not break at minus 40°70 hours.

12. Warehousing: tens of millions of huge sums of money to build the first six-dimensional fully automatic unmanned warehouse in a domestic private enterprise has 15,000+ counters, a storage area of 20,000+ square meters, and a total inventory of up to 3.5 million finished products to ensure delivery Efficient accuracy of the period.
