Heat Exchanger Parts Manufacturers

HEC Machinery is specialized in complex aluminium castings for example heat exchanger parts. These complex parts have a lot of sand cores and are produced in our facilities with a capacity of 70.000 ton of aluminium per year where we offer sand casting, shell core, gravity casting and die-casting

The material of heat exchanger parts is EN1706/AC43000. We have various types of heat exchanger parts to match 18kw-2800kw condensing boilers.

As for heat exchanger parts, the casting structure is complex and difficult to cast and mainly consists of pins and water channels. The core making uses different mesh size of sand to find the right balance in strength and gas release to avoid shrinkage or core breakage. Multiple combinations of cold and hot core assemblies with moulding sand patterns or shell cores. Casting wall thickness requires equalization therefore the precision of core assembly is highly demanding. Grain refinement, modification and density index need to be accurately controlled during melting to ensure that the tightness, structure, as well as the chemical and mechanical properties all meet the required ranges. Subsequently the process requires a 100% leak test, usually with air pressure or an hydraulic pressure test carried out by the foundry.

Certificates:ISO 9001:2015, ISO 14001:2004 certified and ASME certification

We have established long-term and stable cooperative relations with many of the world's top 500 enterprises and set up a sales office, R&D, storage warehouse, assembly line and laboratory in Belfeld, the Netherlands, our Dutch and Chinese technical engineers and casting/machining specialists can provide services beyond your expectations, giving advice on the feasibility and cast-ability of the design so as to help customers to save time and cost, giving you the necessary support on a successful launch of your project.
