Which one is the best choice for you?

The final choice of which company to use as your silicone products manufacturing partner requires many considerations, the core of which is the production cost of the same quality. Over the past few decades, American-made high-quality and superior service, even accurate costs, have allowed you to choose to use American suppliers as your supply chain. As the global technology-sharing process accelerates and equipment suppliers continue to carry out technological innovations and improve supply chains and management systems, China's manufacturing and service levels have made a qualitative leap, and manufacturing innovation in some fields has even surpassed American companies. Sometimes for tiny projects, your team will have to go to a silicone products manufacturer for an on-site audit to confirm whether their in-house capabilities meet your product needs. This makes your overall costs higher.
