International automotive tier 1 and 2 suppliers and other industrial sectors acknowledge FJ Industries as being a reliable and competitive partner in supplying iron and steel cast and machined components.

Over more than a decade, our production plant in Ningbo has developed a very strong supplier network for iron and steel castings. All raw cast components are machined, quality tested and inspected in-house, at our production plant in Ningbo, before delivery to our customers or oversea warehouses.

FJ Industries collaborates solely with TS16949 certified foundries and our casting engineers and SQEs frequently conduct onsite inspections of the foundries, both during project development and serial production. We encourage our customers to co-visit or audit our raw casting suppliers together with FJ Industries.

FJ Industries has the know how and competences to participate in early supplier involvement in order to ensure component designs that are fit for the desired application, but also for manufacturing. We offer our customers advice and access to our technical experts in the design phases.


Watch our casting and machining processes
Investment casting

The investment casting process, also called lost wax casting or precision casting, has many advantages compared to other manufacturing processes.

– Ability to produce complex and near net shape parts thus keeping costs at a minimum.

– All steel alloys incl. ferritic and austenitic stainless steel can be produced.

– Very little material waste.

– Process suitable for both small and large volumes.

Sand casting

Depending on component design, material and other technical requirements we use either coated sand or black sand casting. As we are cooperating with several sand casting foundries, some with automatic casting lines, some with manual processes, we have the ability to produce and deliver both small and large volumes.

We produce parts in various ductile iron grades, including SiMo grades, and grey cast iron.


Most cast, cold drawn or forged components require a subsequent machining process. At FJ Industries we do high precision CNC machining operations on medium and high volume components in steel, stainless steel (austenitic and ferritic grades) or cast iron.

Highly skilled engineers at our plant in China and Denmark cooperate closely in order to develop the optimal serial production setup ensuring high process capability at low cost. Being a TS16949 certified company the guidelines in APQP and PPAP are always followed.
