Dalian hollow forming mould industry is known as the "magnetic industry" of "turning iron into gold" in Europe, America and other industrial developed countries. Almost all products in daily life are the products of different types of molds: all plastic products (including TV, refrigerator, air conditioning shell, even wires, beverage bottles, PVC water pipes, toilet sewer pipes), all sheet metal parts (such as your computer chassis), all die castings (such as door handles, belt buckles, metal zippers).
High technical application professionals with good professional quality, facing the manufacturing industry, engaged in mold design, mold processing process preparation, stamping and plastic forming processing, CNC machine tool operation and production management. It is reflected in the technician level of mold manufacturing in manufacturing and the assistant designer level in design.
Avoid the depressing feeling of customers caused by too large low height space. Steel wood building formwork, building plywood, steel bamboo building formwork, aluminum building formwork, plastic building formwork, etc. Due to its long chain structure and the flexibility of molecular chain, generally, the polymer is placed at a certain temperature. If the temperature is reduced below Tg (or crystallization temperature) before the recovery of high elastic deformation, and then the external force is released, the relaxation time will be reduced.
The greater the proportion of irreversible deformation in the product, the better the shape stability of the formed product. The formation of pipe blank: it is extruded by the extruder and hung in the pre separated cavity directly below the head; The parison is molded on a metal pipe by injection molding, one end of the pipe is filled with compressed air, and the pipe wall at the other end is provided with micropores.
