Set size of a cavity and core.
plastic parts of external and internal shape is formed directly by the cavity and core, these complex multiple-layered surface processing difficulty is bigger, especially within the blind groove cavity forming surface processing, using traditional machining method, not only requires workers technical level is high, the auxiliary fixture, cutting tools, and processing cycle is long.
the precision and surface quality requirement is high, long service life.
the current common plastic parts dimension accuracy requirement for IT6 - 7, the surface roughness Ra0. 2 - 0. 1 microns, the corresponding injection mould parts to IT5 - dimensional accuracy requirements 6, the surface roughness Ra0. Below 1 microns.
laser disc recording surface roughness to achieve mirror machining level of 0. 02 - 0. 01 microns which requires the mold surface roughness reaches 0. 01 mu m below. Long life injection mould is very necessary for improve efficiency and reduce cost, at present the service life of the injection mould generally requires more than 1 million times.
precision injection mold with large formwork stiffness, increasing the thickness of the template, or conical positioning components increase supporting columns in order to prevent the deformation after mold under pressure, sometimes internal pressure can reach 100 mpa.
the ejection device is the important factors influencing the deformation and the dimensional accuracy, so you should choose the best out of points, so that the demoulding uniform everywhere. High precision injection mold in the structure of the majority of the framed structure of or whole put together, this requires the mold parts processing precision and interchangeability are greatly improved.
long process flow, production time is tight.
for injection molded parts, mostly to other parts of the complete product, and in many cases are in other parts has been completed, anxiously waiting for the matching of molded parts. Because the shape or size precision requirements for products is very high, and due to the different characteristics of the resin material, mould manufacturing is completed, also need to repeatedly test and correction, make the development and delivery of the goods time very nervous.
different design, different manufacture.
mould manufacturing is not the ultimate goal, but the users put forward eventually products design, mould making factory according to user requirements, design and manufacture of molds and in most cases, the products of injection production but also in other factory. Thus causing the product design, mold design and manufacturing and products of the production of long distance.
professional division of labor, the dynamic combination.
mold production batch is small, generally belong to single production, but the mould need a lot of standard parts, large formwork, small to thimble, these can't also cannot do, only by a single manufacturer and manufacturing process is complex, common equipment and CNC equipment use very unequal.
