Composite material is a material with new properties composed of two or more materials with different properties by physical or chemical methods. With the expansion of the application field of composite materials, the composite material molding industry has developed rapidly, the old molding process is improving, and new molding methods are emerging. Common processes include hand paste molding, spray molding, resin injection (RTM), molding (BMC, SMC), vacuum flow guiding molding, etc.
To make high-precision composite products, composite mold is the most important part of the whole manufacturing process. And the shape and appearance of the product need to be guaranteed by the mold. The composite material mold usually puts the composite material into the hot pressing mold, and then melts the composite material by heating the mold. The mold is provided with an ejection mechanism, which can eject the molded product and separate it from the mold. Common heating methods of composite mold include oil heating, electric heating, steam heating, etc.
Composite molds are very different, depending on the industry and application, involving many fields such as automobile, electricity, sanitary ware, building materials, aerospace and so on. Compared with metal mold, composite mold has many advantages. What are the advantages of composite mold?
1. The composite mold is light in weight, and the reduced weight is helpful for transportation in the mold.
2. Lower specific heat capacity, less heat required during processing, and easier to control the rise and fall of curing temperature, thus shortening the time through the autoclave.
3. The manufacturing and maintenance costs are low. The composite mold uses a common main mold to form multiple repeated molds.
WYD, as a mature composite mold manufacturer in China, manufactures various types of glass fiber composite molds (glass fiber reinforced plastic molds, such as SMC, BMC, LFT, carbon fiber composite molds and lwrt composite molds).
WYD has produced the following molds: spoiler template, fender, bumper, front panel mold on trucks, hood, door, bottom guard, roof, seat back, trunk mold on cars, and basin mold for electrical boxes and bathroom door panels. The composite molds we produce, after effective optimization, have longer service life, lower manufacturing cost and higher accuracy.
