Introduction of composite material PCM process
The PCM molding process is a process in which a semi-finished carbon fiber composite material that has been stamped is put into a mold and molded by a contour scanning spray curing process. This process first needs to design the cast, and through the three-dimensional computer processing to obtain the three-dimensional model of the cast, from its data conversion to obtain the layered pattern cross-sectional profile data, to generate control information. Then, the resin nozzle is controlled on the PCM rapid prototyping machine to evenly spread the resin on the surface of the core sand, and the curing of the model is preheated and accelerated after one layer is completed. The PCM molding process, also known as compression molding, is a molding method in which the stamped semi-finished carbon fiber composite material is pre-placed into a mold, and then heated and pressurized to form and solidify. Among them, the forming blank before hot pressing is the key to realize rapid manufacturing.

Molding process of prepreg
Prepreg molding process: including vacuum bag process, autoclave process, molding process, coil process, pultrusion process, winding molding process, pressure bag process. These processes have their own characteristics, such as vacuum bag process through the vacuum to the product pressure, heating, to obtain excellent performance products.

Composite Materials and Their Applications
Composite materials are formed by the combination of two or more constituent materials with significantly different physical or chemical properties, and are new materials with additional properties.
Qualified Designer
Mold as the "mother of industry" plays an important role in the development of the national economy, our daily life of all kinds of daily necessities are inseparable from the mass production of mold. In the fields of electronics, automobiles, home appliances and communications, 60%-80% of parts rely on mold forming. The parts produced by the mold have high precision, high complexity, high consistency, high productivity and low consumption, which are unmatched by other processing technologies. The mold is also a "benefit amplifier", and the value of the final product produced by the mold is often dozens of times or hundreds of times the value of the mold itself. At present, the annual output value of molds in the world is about 60 billion US dollars, and the level of mold production technology has become an important symbol to measure the level of a country's product manufacturing.
Acceptance criteria for good molds
Today, I want to explain to you the acceptance criteria of mold products. We mainly analyze the appearance, size and material of the mold. Let's take a look.
