Customers put forward material requirement, mechanical properties and tolerance, maybe full set of engineering Drawing, designing requirement, then our manufacturer will termwise check drawings scrupulously and completely understand technical parameter.There'll be once or twice technical exchange between both parties, or any ameliorating. Everything is ready, next to manufacturing, acceptance and delivery.

We are looking forward to your inqury with detailed requirements.
