Mold is used to shape the specific shape of a certain shape and size of products tools used by the products of different raw materials, different methods shaped general layout will be divided into plastic molds, metal stamping dies, metal die-casting molds, rubber molds, glass molds. It is used in the daily life of products and various mechanical parts, mostly in the shape of heads through to finishe products, it has become a major instrument manufacturing industry. In the field of macromolecular materials for plastic products shape the instrument, known as plastic molding shape. Plastic molds optimized design is contemporary in the field of macromolecular materials processing major issue.
The graduation design is fanner knob and, it will reach request: to high temperature, insulation can strong sex is better, resistance to climate, rigid, toughness good, through various performance analysis of products, choose materials for ABS, the thickness of plastic parts for 1mm, tolerance grade IT5 level for. It is used to regulate the speed and timing, can satisfy people's hot weather blowback for wind and length of requirements, while also play beautiful role.
