Dark horse in the field of cosmetics packaging production mold: the RP rapid tooling

In the early, rapid prototyping manufacturing ( RP) The rapid die manufacturing technology, in the field of general mould manufacturing got only a small share. But as the ( RT） The development of technology, RT technology has won the market recognition in the field of such processing, the reason is that this kind of processing of RT material impact resistance, pressure resistance and heat resistance requirements is low. Hot forming is one of the first to adopt the technology of processing method, because it needs under the condition of low heating processing, and use rapid tooling is more easy to control the process. Rapid prototyping manufacturing is usually divided into, fused deposition molding ( FDM） , 3 d printing and stereo lithography ( SL) 。 Using rapid prototyping development of hand-board model has low cost, short time, the advantages of the application of rapid tooling is more comprehensive and universal plastic products in the rapid prototyping method has more advantages.
in the field of plastic molding, for holding water and carbonated soft drinks ( CSD） PET cosmetics packaging production and development of prototype mold has important significance. Using FDM technology, can make the prototype product development cycle from the previous weeks was reduced to less than 5 days. In addition, the cost of PC prototype mold base is aluminum mold of 1/3 to 1/2. Therefore, Stratasys usually recommend use PC material for plastic mould. It is said that it can withstand hundreds to thousands of HDPE, PET, PVC, PS or PC products of short-term production tasks.
in meet the application requirements, PPSF than ABS and PC with higher glass transition temperature ( Tg） 。 According to different mold and molding products material, FDM the life of the mould is in commonly 100 ~ 1 000. In addition to the porosity of the exhaust ( Like forming) And additional outside oblique muscle around, its mold design and is very similar to the typical machining mould. Despite the cooling waterway can be built in FDM mould, but it is generally believed that USES the standard installation base plate with a cooling channel line will be more quick.
