Customer Reviews
Reliable 5-axis machining supplier for auto aftermarket parts
We have cooperated with Songben Xinke for 2 years on custom aluminum performance auto parts. Their 5-axis machining capability perfectly handles complex curved turbo housings with tight 0.002mm tolerance. The prototype lead time is short, and all finished parts pass full dimension inspection before shipment. Technical team gives professional optimization suggestions on our drawings, greatly reducing our production cost. Highly recommended for automotive modification manufacturers.

Stable quality large gear & transmission shaft manufacturer
We ordered batches of helical gears and gear shafts for our heavy-duty reducer equipment. The gear grinding precision meets AGMA standard perfectly, the surface finish is smooth and running noise is much lower than our previous supplier. They support full heat treatment and one-stop delivery, delivery schedule is always on time. Their factory has complete testing equipment, we receive detailed inspection reports with every order. A trustworthy long-term transmission parts partner.

Micron-level precision semiconductor mold solutions
Our packaging plant needed custom QFN & BGA encapsulation molds with ultra-tiny tolerance. Songben Xinke’s ultra-precision EDM & wire cutting technology achieved 0.001mm accuracy, effectively reducing chip scrapping rate during our mass production. The mold inserts wear resistance is excellent, after thousands of molding cycles the dimension still stays stable. The after-sales support is responsive whenever we need mold repair or modification. We will keep placing repeat orders.
