In short, china is a tool that is used to make shaped objects. The tool consists of various parts, and different molds are made of different parts. It is mainly through the physical state of the material changes to achieve the shape of the object processing. Mold is under the action of external force into the blank has a specific shape and size of the tool parts.
China mould is a model, according to this model to make products, but how the mold is produced, it may be in addition to die professionals most can not answer. Mold has played an irreplaceable role in our lives, most of our daily necessities are inseparable from the mold, such as computers, telephones, fax machines, keyboards, cups and so on these plastic products Needless to say. In addition, like the car and motorcycle engine cover is made out of molds, light a car a variety of molds to use more than 20,000. Therefore, the role of modern life mold irreplaceable. As long as the mass production can not be separated mold.
Because different China moulds have been applied in many fields, combined with the professional mold manufacturing technology in these years have also been some changes in the development, so in this section, summed up the general design rules vacuum plastic mold. When the mold output is small, it can be made of wood or resin. However, if the experimental mold is used to obtain data on the shrinkage, dimensional stability and cycle time of the product, it should be tested using a single-cavity mold and guaranteed to be used under production conditions.
Design, often have to consider the dimensional stability and surface quality. For example, the design and dimensional stability of a product require the use of a female mold (female mold), but the product requiring a higher gloss on the surface requires the use of a male mold (male mold) so that the plastic parts ordering party will take both into consideration Point, so that products can be produced under the best conditions. Experience has shown that designs that do not meet the actual processing conditions often fail.
