Our history

1998

Qingdao Delifeng Machinery Co., Ltd (aka DLF) was founded by Mr. Xiude Song to manufacture construction hardware for supply to US market through a local trading company, products then were coil and ferrule inserts only, it was known later that we were the first foreign company manufacturing such products for supply to US.

2005

Believe or not, but it's true that DLF had been focusing on manufacturing only coil and ferrule inserts for 7years till 2005 when a customer brought a new item to Mr. Song asking him whether or not he could make it in China. This new item is a flat steel anchor (aka Concrete Lifting Anchor, Fleet Lift Anchor, Rapid Lift Anchor etc) for precast concrete lifting. Mr. Song said yes after 7months by providing his customer conforming samples along with attractive pricing. Before sampling, lots of experiments had been performed with the newly added production and test equipments.

After 25years, coil and ferrule inserts still proudly remain in our wide range of products nowadays. Flat steel anchor became our second product series in 2005 till today.

Besides capabilities in metal stamping and welding, significant funds were invested into new equipments to include die casting in our production capabilities. A new factory for die casted products was built up 3miles away from the old factory which is still in operation today for construction hardware.

Right from here, DLF started to manufacture water pump impeller in its old factory and water pump housing in its new factory, both were then and are now still supplying to a world leading manufacturer of water pump for vehicle cooling system.

Along with more and more customers coming in, DLF's construction hardware was greatly expanded to cover nearly all products in the field of forming and concrete precast.
