Problems solved by technology

The disadvantage of this operation method is that the entire process of product realization requires two procedures of hot pressing mold pressing and plastic mold injection molding. The process is more complicated, resulting in low efficiency and high cost, which cannot meet the needs of mass production in the 3C industry.
[0007] In addition, in the current technology, there is no technical solution for using insert molding (Insert Molding) combined with two-shot method to make thermoplastic composite products

Abstract

The invention belongs to the field of thermoplastic composite product manufacturing and particularly relates to a manufacturing method of a thermoplastic composite product and a corresponding productof the manufacturing method. According to the manufacturing method of the thermoplastic composite product, a thermoplastic composite plate is heated in an infrared heating mode, after heating, the thermoplastic composite plate is directly placed in a first injection mold body of a double injection mold to be pressed into a 3D shape, and an ebonite material is injected; and then the thermoplastic composite plate rotatably enters a second injection mold body of the double injection mold, and a polyethylene material is injected. The product is generated after manufacturing through the manufacturing method of the thermoplastic composite product. Thus, the strong, firm, light, thin and functional product can be obtained, the overall yield is increased, the manufacturing procedure is simple, theforming time is short, the efficiency is high, and the requirements for mass production in 3C industries can be met.

Description

【Technical field】 [0001] The invention belongs to the production field of thermoplastic composite material products, and in particular relates to a production method of thermoplastic composite material products and corresponding products. 【Background technique】 [0002] With the development of electrical and electronic equipment and information equipment such as notebook PCs, tablet PCs, mobile phones, cameras, and portable information terminals, there is a strong demand for thin and lightweight products in the market. Thin and light products will constitute the outer shell or internal parts of the product with thin walls. While the product is required to be light and thin, it also requires high strength and high rigidity. [0003] Thermoplastic composite materials have the advantages of light weight, high specific strength and specific modulus, chemical corrosion resistance, fatigue resistance, and easy integral molding, and are widely used in the production of military, ai...
