This is a new technology that can be used to produce composite plastics products without using molds. As it is well-known that all kinds of plastics articles are made with some kinds of molds. Since cost of the molds constitutes a substantial share of thetotal costs when mediumsized and large-sized plastics articles are produced in small lots, the production cost will be so high and production period so long, that the customers can not afford to pay for them. This invention can be used to produce mediumsized and large-sized plastics articles such as tubes, shafts, cases, barrels, jars, containers and sanitary implements by using braided fine bamboostrips into forms and treating such forms with plastics materials, and plastics will take the shape of these forms without molds. In this way production periods can be very short and the cost of the mold can be saved. The quality of products is very good.
