SMC mold is a combination plastic mold used for compression molding, extrusion molding, injection molding, blow molding, and low foaming molding. It mainly consists of a concave mold with a variable cavity composed of a concave mold combination substrate, a concave mold component, and a concave mold combination card plate, and a convex mold with a variable core composed of a convex mold combination substrate, convex mold component, convex mold combination card plate, cavity cutting component, and side cutting combination plate. Coordinated changes in the convex, concave, and auxiliary molding systems of molds. Can process a series of plastic parts with different shapes and sizes. The plastic processing industry is equipped with plastic molding machines to give plastic products a complete configuration and accurate size.
Due to the complex types and processing methods of plastics, as well as the varying structures of plastic molding machines and plastic products, there are also various types and structures of plastic molds.
We have made a common summary about the laying of SMC fiberglass molds, in order to provide thoughtful service to our customers, improve our theoretical knowledge and practical operation ability, and also to enable our customers to have a simple understanding of SMC fiberglass molds.
SMC fiberglass mold laying steps:
1： After the initial solidification of SMC fiberglass mold coating, the initial layer can be laid. The laying process cannot be too fast, usually 2-3 layers of fiberglass cloth or fiberglass felt are laid per day.
2： Laying requires a certain amount of mold resin. The function of this resin is superior to that of ordinary resins. During the laying process, workers need to mix adhesive, which means adding a promoter and curing agent to the resin.
3： Apply glue with adhesive material, lay a layer of fiberglass fabric and apply another layer of glue. Use an iron roller to flatten the fabric, remove any bubbles, and make the glue even. After reaching the specified thickness, the laying is completed.
In general, the thickness of the mold should reach 3-5 times the thickness of the product. So the laying time is usually longer, it can continue for 6-7 days.
