The working principle of FRP pultrusion equipment is to heat and solidify the glass fiber and resin in the mold, then use two clamping traction gantries for alternate movement, and then pull out the product continuously. Thus, you can get all kinds of FRP that users need profiles.
The hydraulic pultrusion machine consists of three parts: mechanical, hydraulic, and electrical. The mechanical part of the FRP pultrusion equipment is composed of a heating frame, a frame, and two clamping gantry. The hydraulic part of the FRP pultrusion equipment is composed of two mutually independent hydraulic systems, which are respectively composed of an oil pump, a clamping cylinder, and a thrust cylinder. It is composed of an integrated valve block, speed control valve, oil filter valve, oil filter, cooler, and oil tank. The electrical part of the FRP pultrusion machine includes the heating part, temperature control part, control part, and cabinet part. According to the different traction forces, the hydraulic pultrusion machine is divided into different traction forces. The choice of the size of the traction force depends on the specification of the FRP profile. The benefits of hydraulic pultrusion machines include simple and continuous operation, low operating costs, high reliability, and high production efficiency. Therefore, it is currently widely used in the manufacture of corrosion-resistant products for the corrosion of certain media (such as hydrochloric acid, chlorine, carbon dioxide, dilute sulfuric acid, sodium hypochlorite, and sulfur dioxide, etc.) that stainless steel cannot deal with, and has played a good role.
The pultrusion profile produced by FRP pultrusion equipment has good performance, will not corrode, and rarely scales, so it can manufacture various fluid pipes. Because the friction coefficient is very low, it saves a lot of power.
