Points you may concern:
Customization - Can your machine or other products be customized?
Ronniewell: Sure. As a professional manufacturer, we have our own engineer team, who is good at design, develop & build special solution catering for your individual requirement.
Transportation-What about the transportation?
Ronniewell: Seaway is the most common transportation way for oversea trading. Depends on your location, combined transport by rail and sea is also an option. Certainly railway transportation is also acceptable if it is the most suitable approach.
After sale service - What about the after-sale service?
Ronniewell: We provide 12month guaranty period for the whole machine quality. During this time, any issue proved because of the machine flaw itself,we would take the whole responsibility of it. Except of the guaranty period,technical advisory support is available freely covering the whole using life of the machine. Engineer service on user premises is also available for necessary.
