Dandong Hengrui Machinery specializes in supplying sand casting, precision casting, forging, machining and other kinds of metal parts, including valve parts, pump parts, laboratory equipment parts, electrical parts, automotive parts, railroad parts, marine parts, construction equipment parts, drainage parts, mining parts, as well as any shaped parts customized according to specific technical drawings or samples. We have an automated production line for sand castings (cast iron parts), advanced technology and first-class testing equipment to ensure high precision and stable quality, so that we can meet special requirements for all aspects of size, pressure, hardness, surface roughness and so on.
Material : Iron, steel, copper, aluminum, etc.
Workmanship : Sand casting
Surface treatment: On request
Application: Flow control
High-quality materials: the butterfly valve body is made of high-quality cast iron and cast steel, with high strength and durability, capable of withstanding various pressures and adapting to the complex environment of industrial applications and urban infrastructure; at the same time, non-ferrous metals, such as copper, aluminum, etc., provide more choices for special application scenarios.
Exquisite technology: sand casting technology is mature, with automated production lines, with advanced CNC machining equipment, to ensure that the product dimensions are accurate and the surface finish is high; from the procurement of raw materials to the post-production inspection of the whole process of strict control, to ensure that each butterfly valve fittings are in line with high standards.

1. Are you a manufacturer or a trading company?
We are a professional manufacturer with over 20 years' experience for designing and producing casting parts and machining parts.
2. How can I get some samples?
If you need, we are glad to offer you samples for free, but the new clients are expected to pay the mould cost and courier cost.
3. Can you make casting according to our drawing?
Yes, we can make casting according to your drawing, 2D drawing, or 3D cad model, both available. If the 3D cad model can be supplied, the development of the tooling can be more efficient. But if without 3D, based on 2D drawing we can still make the samples properly approved.
4. Can you make casting based on our samples?
Yes, we can make measurement based on your samples to make drawings for tooling making.
5. What's your quality control device in house?
We have spectrometer in house to monitor the chemical property, tensile test machine to control the mechanical property and UT Sonic as NDT checking method to control the casting detect under the surface of cast.
