Abstract: By extrusion moulding, the soaked plastic bamboo thread can be et pressed to the textile shuttles, with easier processing, higher strength and veluable properties. So they can replace wooden textile shuttles.The design and mould-making are very important in manufacturing mouldings, by which the properties and cost of moulding are decided.The moulds introduced in this paper are easier and quicker in the operation of moulding unloading. The mould is small in size and efficient in heat transfer. In addition, the lower production cost of textile shuttles can be reached.
