Working together with our manufacturing partners, EMAC continuously collects all useful information, tips, and other technical literature, such as tips on product design, tips on product selection, and shares other technical information. In the meantime, EMAC also invested in different kinds of testing to verify the uncertainty of products, such as the impact on the engine power losses of modifying the dry-type engine exhaust system into a water-cooled exhaust system. All this information is very useful for customers to choose the right products and design the products accordingly.
EMAC pays extreme attention to the new products, new applications, and product trends of our industry, to make sure that we follow up with the dynamic changes of the machinery industry. We collect the trends of products and technology development within the machinery industry. And our project case library can help all customers to find similar cases for most applications, or help customers to find an EMAC’s customer in their country or region.
