Injection mold has the following characteristics:
Single-piece production, high cost of manufacturing.
Injection molds can not be as basic as other machinery can be used as a product at any time in the mechanical and electrical market to buy. Because each set of injection molds are specific to the specifications of plastic products produced, because of the shape of plastic products, size, the gap is very large, its injection mold structure is also large similar to the chamber, so injection mold manufacturing can not form mass production. Injection Mold The longer the lifespan, the less likely it is to repeat the process.
Second, the manufacturing cycle is short.
Because the injection mold is for the product of the plastic products and custom-made, as a product, in addition to quality, price factors, it is important to quickly put the market.
Third, technical stronger.
Injection mold processing engineering focused on the mechanical manufacturing of advanced technology part of the essence and Fitter Technology manual skills, Injection Mold therefore require injection mold workers have a high cultural level to adapt to the requirements of many types of work.
Injection mold Manufacturing has 5 distinct characteristics, the analysis is as follows:
1, the cavity and the core are three-dimensional surface.
The outer and inner shapes of the plastic parts are formed directly by the cavity and the core, these complex three-dimensional surface machining difficulty is relatively large, Injection Mold especially the cavity of the blind hole-shaped surface processing, if the use of traditional processing methods, not only the high level of technical workers, auxiliary fixture more, tool, and processing cycle length.
2, high precision and surface quality requirements, long service life requirements.
At present, the size accuracy of general plastic parts requires it6-7, surface roughness Ra0.2-0.1μm, the corresponding injection mold parts dimension accuracy requirements to achieve it5-6, surface roughness Ra0. The roughness of the laser disk recording surface must reach the level of mirror processing 0.02-0.01μm This requires the surface roughness of the injection mold to reach 0.01μm below.
Long life injection mold for the improvement of high efficiency and reduce the cost is very necessary, at present the service life of injection mold generally requires more than 1 million times. Injection Mold Precision injection mold To use a large stiffness of the mold, to increase the thickness of the template, to increase the support column or cone-shaped positioning elements to prevent the injection mold under pressure to produce deformation, Injection Mold sometimes the internal pressure can reach 100MPa. The ejector device is an important factor which affects the deformation and the precision of the product, so the best ejection point should be chosen so as to make the demoulding evenly. High-precision injection mold in the structure of most of the use of a mosaic or the entire structure, Injection Mold which requires injection mold parts processing precision, interchangeability is greatly improved.
3, the process is long, manufacturing time is tight.
Injection mold expert Rob that, for the injection molded parts, mostly with other components supporting the complete composition of the product, and in many cases is in other parts have been completed, Injection Mold eagerly awaiting injection parts of the supporting listing. Because of the high accuracy of the shape or size of the product, and because of the different characteristics of the resin material, injection molding mold After the completion of the manufacturing, but also the need to repeatedly model and modify, so that the development and delivery time is very tense.
4, off-site design, manufacturing in different places.
Injection mold Manufacturing is not the ultimate goal, but by the user to propose the final product design, injection mold manufacturers According to user requirements, Injection Mold design and manufacture of injection molds and in most cases, the injection of products in other manufacturers. This results in the design of the product, injection mold design and manufacture and production of products in different situations.
5, professional Division of labor, dynamic combination.
Injection Mold production batch small, generally belong to a single piece of production, Injection Mold but the injection mold needs a lot of standard parts, large to die, small to thimble, these can not be done by a single manufacturer alone, and the manufacturing process complex, common equipment and CNC equipment use extremely uneven.
