In 2016, BMW factories experienced a shortage of precision dowel pins that lead to a halt in production of BMW 5 Series vehicles. Normally, these production facilities would seek out precision dowel pins from local suppliers, but in this case, that proved difficult as the pins from local suppliers did not meet their requirements as they experienced problems with unstable gauges, wear, and other defects. BMW was finally able to remedy the situation by discovering Yukai for the supply of their precision dowel pins. Downtime like this can be costly and the German automobile giant had found their solution in Yukai.
Yukai products are always strictly measured according to high standards. The materials we use to manufacture precision dowel pins comply with SKD11 standards and their hardness is HRC58. Additionally, we apply a special surface coating to enhance the hardness, reduce friction, and improve the service life of the products.
Following several instances of cooperation for the supply of small batches of products, our dowels have been widely praised by the welding department of BMW tasked with the production of BMW 5 series vehicles. Now, we have signed a formal contract, making us a qualified supplier.
