Plastic injection molding processing must be injection mold, if it is a simple injection molded parts, then the mould manufacturing is relatively easy, if there are any complex structure of the injection molded parts, injection moulds on manufacturing also has certain difficulty, small built to share these injection molding plant.
the difficulty, plastic mold cavity and core is three-dimensional.
plastic parts from top to bottom shape is formed by the cavity and core directly. These complex three-dimensional curved surface are difficult to machining, especially for blind groove cavity surface. Using traditional machining method, not only requires workers technical level is high, the auxiliary tools, cutting tools, and processing cycle is long.
two difficulties, high precision and surface quality of molded parts, long service life.
at present, the general plastic parts for it6 - dimensional accuracy requirements 7, the surface roughness Ra0. 2 - 0. 1μ M, the corresponding dimension accuracy requirement for it5 - of molded parts 6, the surface roughness Ra0. 1μ M, and the following.
precision injection mould with rigid large formwork, increase the thickness of mould, add columns or cone positioning components, prevent mold compression deformation. Sometimes within a pressure of 100 mpa.
the difficulty, plastic three long process, short production time.
for injection molded parts, mostly to other parts of form a complete set of complete products, in many cases, have on other parts, waiting for the matching of molded parts. Due to the shape of the products or high dimension accuracy requirement, and the characteristics of resin material, after the completion of mould manufacturing requires repeated testing mold and modification, which makes the development and delivery time is very nervous.
the difficulties in four, injection molded parts and mold design, manufacturing.
not mould manufacturing. The final purpose, and. Product design is put forward by the user. According to user requirements, mold manufacturers design and manufacture of molds, in most circumstances, injection molding production of products is also in other factory. Thus, product design, mold design and manufacturing and production in different place.
whether plastic products, injection molding processing factory first need to do is to mold development difficulty assessment, the difficulty is, the higher the fees must also.
