Drennan is a business to business, single source manufacturing service provider in China. We manage a portfolio of qualified manufacturers enabling us to provide quality sub-assemblies using multiple industrial processes. Through joint design, joint development, manufacture, assembly and logistics, Drennan works with customers to bring their ideas to market.

Traditionally, producers would have dealt with many specialized sub-suppliers such as foundries, machine shops, and paint shops. Drennan's Multiprocess Manufacturing Solutions simplify your supply chain, allowing you to concentrate on getting your product to market.
    
Naturally, Drennan can also supply single process solutions such as precision cast parts and forging but the real value advantage is in our Multiprocess Solutions. To give you an idea of what we can do, look at a product we've supplied in the past.

The production we offer include investment casting, die casting, sand casting, forging, machining, welding, fabrication, stamping, pressing, tubing, bending, injection moulding, blow moulding, vacuum moulding, assembling, testing as well as packaging.
