印度采购需求：Upvc 窗户制造机、数控加工中心、数控型材切割机、铝加工机

I'm looking for information on a seamless welding machine suitable for UPVC profiles, as well as a double-head cutting machine for both UPVC and aluminum materials. Please provide details about your available models, including specifications, pricing, and lead times. Additionally, I would appreciate if you could share any options for customization or add-ons that may enhance these machines' performance. It would also be great to know about your warranty and after-sales support. Looking forward to your prompt response!
