Company Overiew

Foshan Zeren Precision Casting Co., Ltd. was founded in 2009, with a precision casting plant and a mechanical processing plant, located at Foshan, Guangdong, China.

We use advanced investment casting(lost wax casting) process for precision castings production, which are made of stainless steel, carbon steel and alloy steel, etc.

We can provide subsequent machining of casting, we also passed and implemented the ISO9001:2015 quality management system.

Main Business

Our company focuses on the lost-wax investment casting products, offer mold manufacturing, CNC machining, polishing, surface treatment and other design services.

From stainless steel investment castings to carbon steel investment castings, we keep you ahead of the competition. Our attention to detail using precision casting and the machining techniques produces the highest quality steel castings for various industries.

Our Quality Services Include

  • Industry leading delivery and "customized" service
  • Production from a ounces to approximately 150 pounds
  • Creative engineering to keep your costs down
  • Flexible volume capabilities
  • Adherence to world-wide standards and specs
  • An arsenal of value-added services and processes involving casting, CNC machining, surface treatment and assembly - just ask

Casting Analysis & Design

IS INVESTMENT CASTING RIGHT FOR YOUR COMPONENT? No two casting projects are the same and with different projects, there are different solutions.

Mould Manufacturing

Zeren’s proprietary, mold manufacturing process technology is designed to measure and correct dimensional issues during the mould manufacturing process.

Lost Wax Investment Casting

All of our items are silica sol investment casting with better surface roughness Ra3.2, instead of water glass investment casting Ra12.5.

Secondary Machining

With full high-speed CNC machining in-house, we can quickly perform any necessar y machining quickly and cost-effectively.

As the member of China Foundry Association, we execute the same size tolerance and material standards as Europe and America. The product conforms to the ROHS standard, the casting surface roughness is around in Ra 3.2, and weight range is from 1 gram to 30 kg. The size range, one direction can reach to 600mm, while the other two directions can reach to 400mm. We has a full set of precision casting and testing equipment, including Wax injection machine, Shell making equipment, Dewaxing kettle, Mid-frequency furnace, Shot-blasting machine, Cutting machine, Grinding machine, Hydraulic press machine, 3D printer, Direct reading spectrometer, Hardness machine, etc.


Our machining plant has machining centers, CNC lathes, EDM (Electrical Discharge Machining), wire cutting machines, Milling machines, Lathes, 3D counting machines and many other complete sets of processing equipment. Our senior engineers and mechanical engineers have over 20 years’ experience in casting and machining field and product development. Sure we have a team of high-skilled and high-quality professional technicians.


The application of casting and machining production is very wide, our main products are: machine parts, engineering machinery, kitchenware, stainless steel faucet, automobile and motorcycle parts, heat-resistant steel parts, hardware tools, lighting accessories, watch shell and crafts, medical equipment, lock valve, electrical appliances, etc.


Our products can be almost cover the whole machine manufacturing industry, and we can provide post-processing procedures for customers, such as: machining, mechanical polishing, electrolytic polishing, electroplating, and electrophoresis, etc. Through the seamless combination of 3D printing and precision casting, we can produce castings of less production, complex and research and development, without mold making. This can save time and cost for our customers.
