What is the precision plastic mold manufacturing technology?

Plastic mold is an abbreviation for combined plastic mold for compression molding, extrusion molding, injection, blow molding and low foam molding. It is a professional process equipment for metal and non-metal pressure forming processing system, and is a special molding tool. It is a special technical product.

The realization of industrialized and commercialized production of plastic molds is a sign of the progress and level of production technology in the manufacturing industry and the technological basis for the modernization of manufacturing.

The basis of plastic mold manufacturing is the design of plastic molds. Reasonable and correct design is the guarantee for the correct manufacture of plastic molds; the development of plastic mold manufacturing technology is of great significance for improving mold quality, precision and shortening the cycle of manufacturing molds.

With the continuous development of technology, plastic mold manufacturing technology has become an important part of today's manufacturing technology. Such as plastic mold CAD / CAM technology, plastic mold laser rapid prototyping technology, plastic mold precision forming technology, plastic mold ultra-precision processing technology, plastic mold in the design using finite element method, boundary element method for flow, cooling, The dynamic simulation technology of the heat transfer process, the CIMS technology of the plastic mold, and the plastic mold DNM technology and numerical control technology that have been developed cover almost all the current manufacturing technologies.

At present, the general trend of industrial development in China mainly includes precision, high-efficiency, long-life plastic molds and the development of efficient, precise, CNC automatic processing equipment, improving the level of plastic mold manufacturing and the development of plastic molds with multi-station multi-cavity.

Plastic mold manufacturing technology can be divided into the following two stages:

1. Industrial production stage: The use of general-purpose cutting machine tools and EDM machines to achieve mechanization and standardization of production technology. The forming precision of plastic mold parts has reached 0.001mm; its universal parts have been formulated into standards, which have realized mass production and shortened the manufacturing cycle of plastic molds.

2, hand workshop manufacturing stage: mainly rely on the manual skills of plastic mold workers, can only produce a single process die, bakelite stamping and other simple plastic mold.
