Problems solved by technology

[0002] At present, the production of large-scale FRP products is mostly made by hand-lay-up manufacturing process. When producing large-scale products, a large number of molds are required. The manufacturing and maintenance costs of the molds are high, and it takes up a lot of production space. Product production requires a large number of hand-lay-up skilled workers. Production The site occupies a lot, because the resin has an odor, does not meet the requirements of environmental protection, the working conditions of the workers are poor, and the production efficiency is low. It only takes several hours for each product to solidify on the mold after hand lay-up. The daily production capacity of each mold is Two to three products; due to manual operation, the thickness is uneven, the product consistency is poor, and the surface is prone to bubbles after painting, which has many unfavorable factors

Embodiment Construction

[0019] The preferred embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings of typical products.

[0020] Such as Figure 1~4 As shown, the processing tools of the SMC material molding process include a press and a heating system. The processing tools also include a mold. A heating pipeline is installed in the mold. The mold is installed on the press. The surface of the mold cavity can be treated by electroplating. The shape of the mold The cavity is an embedded component, and the cavity and the mold are equipped with a matching connection mechanism, which allows the replacement of the cavity to achieve the purpose of producing different products under a similar design. The SMC material molding process is:

[0021] a. Unpack the SMC material, cut out a suitable size of SMC material, and then weigh it to verify whether it meets the weight requirements.

[0022] b. Turn on the heating system to continuously supply hea...

Abstract

The invention discloses an SMC material molding process, and relates to the technical field of plastic heat treatment. The process heats and pressurizes an SMC material by using a mold, so that the SMC material flows to fully fill in a cavity after being heated to reduce the viscosity, and products with excellent compactness are produced. The process is specifically suitable for processing large SMC products; and compared with a traditional hand pasting process, the SMC material molding process reduces the manpower, largely improves the production efficiency, largely improves the working condition, and prevents the human body harm from the glass steel material forming process.
