The manufacturing process of liquid silicone coated plastic
The manufacturing process of liquid silicone coated plastic is a complex and fine process, involving the selection of materials, pretreatment, mixing, molding, vulcanization and other links.
Design mold: First need to design mold according to the shape and size of the product. Molds are usually made of metal or silicone and are used to shape liquid silicone.
Prepare the mold: The designed mold is processed and treated to ensure that the surface of the mold is smooth, free of scratches and bumps, so as to facilitate subsequent coating and forming. AQ
Prepare liquid silicone: Select the liquid silicone suitable for the product requirements, and mix and stir according to the formula requirements to ensure the uniformity and stability of liquid silicone.
Plastic wrap molding: Place the prepared mold in the molding machine, and then pour the liquid silicone into the mold. The molding machine usually applies pressure and temperature to ensure that the liquid silicone fills the mold adequately and cures quickly.
Curing and demoulding: After a certain period of curing, the liquid silicone will become a solid, and then the molded silicone product can be removed from the mold.
Follow-up treatment: The molded silicone products may need to be trimmed, cleaned and surface treated to ensure the quality and appearance of the product.
Inspection and packaging: Quality inspection of molded silicone products to ensure that the products meet the requirements. It is then packaged for easy transportation and sale.
Finally, the product needs to be post-processed. Post-treatment includes cleaning, inspection, packaging and other steps to ensure the cleanliness, qualification rate and appearance quality of the product. In the post-processing process, the product also needs to perform performance tests to ensure that it meets the relevant standards and customer requirements.
In addition to the above basic process flow, the manufacturing of liquid silicone coated plastics may also involve some auxiliary processes, such as spraying, printing, cutting, etc. These auxiliary processes can be selected and adjusted according to the specific needs of the product to improve the added value and market competitiveness of the product. In general, the manufacturing process of liquid silicone coated plastics includes mold design, preparation, molding, curing, follow-up treatment, inspection and packaging. These steps require strict control of process parameters and quality requirements to ensure the quality and performance of the final product. At the same time, with the continuous progress of science and technology and the constant change of the market, the manufacturing process of liquid silicone plastic also needs to be constantly innovative and improved to meet new needs and challenges.
