I'm looking for a supplier for some spare parts for circular looms. Specifically, I'm interested in plastic plates with a diameter of 120mm, which are essential for the operation of these machines. Additionally, I need bobbin tubes that measure approximately 185mm in length and 37mm in diameter. Quality and durability are critical since these components play a significant role in the loom's performance. Please provide information on pricing, lead times, and any available options you might have for these items. Also, if you offer bulk ordering or discounts for larger quantities, I'd love to hear about that as well. Looking forward to your prompt response!
