Abstract

The invention relates to a method for producing an automobile valve cover or oil pan by using a fiber reinforced modified polypropylene composite material. The method comprises the steps of: producing a fiber reinforced modified polypropylene block by using an extruder, pressing and machining, or also comprises the steps of producing a roughly-produced valve cover or oil pan by using an injection molding machine and machining. The valve cover provided by the invention has the advantages of high temperature and corrosion resistance, high strength, heat ageing resistance and the like, and is low in noise compared with a metal valve cover. The method provided by the invention is simple and easy to operate, is little in investment, and has good economic benefits and good market prospects.

Description

【Technical field】 [0001] The invention belongs to the technical field of manufacturing and processing of auto parts. More specifically, the invention relates to a method for the production of valve cover covers (oil pans) using fiber reinforced modified polypropylene composites. 【Background technique】 [0002] At present, the function of the bonnet cover is to position the valve stem to ensure the normal transmission and switch of the valve stem. At the same time, it has a sealing effect and has a certain strength to prevent the internal fluid from flowing out. Also do not see the patent application of fiber-reinforced plastic bonnet cover at present. CN201080010610 discloses an oil sump comprising a thermoplastic upper portion and a thermoplastic lower portion, each of which includes one or more ribs and joined as At least one rib of the upper portion is engaged to at least one rib of the lower portion. CN 01808595 discloses an oil sump module for an internal combustion ...
