美国采购需求：协作机器人夹爪、磁性机器人夹爪、机械臂夹爪、机器人手臂夹爪、机器人协作夹爪

I'm interested in exploring potential pricing for your product, including shipping costs to the USA. It would be great to have a detailed quote that encompasses all expenses. Additionally, could you provide an estimated shipping timeline for deliveries to the USA? I'm particularly keen on understanding how long it would typically take for the items to arrive once the order is placed. Also, I plan to integrate this product with a robot arm, so having access to a STEP file would be extremely helpful for compatibility checks. If you could send that over along with the pricing details, it would be much appreciated. Please reply to this email so we can discuss this further. Looking forward to your quick response!
