Mould Making Is Very Necessary
Jul 07, 2017

The external and internal shapes of the plastic parts are directly formed by the cavity and the core. These complex three-dimensional surface processing is relatively difficult, Mould Making especially the blind hole type inner surface forming of the cavity. If the traditional processing method is adopted, Requires workers a high level of technology, auxiliary tool fixture, more tools, Mould Making and processing of the long cycle

At present, the dimensional accuracy of plastic parts is generally IT6-7, surface roughness Ra0.2-0.1μm, the corresponding injection mold parts of the dimensional accuracy requirements of IT5-6, Mould Making surface roughness Ra0.1μm below. The roughness of the recording surface of the laser disc is 0.02-0.01 μm at the level of the mirror processing, which requires that the surface roughness of the mold is 0.01 μm or less.

Long life injection mold for improving efficiency and reduce costs is necessary, Mould Making the current life of injection molds generally require more than 1 million times. Precision injection mold with a large modulus of the mold, increase the thickness of the template to increase the support column or tapered positioning elements to prevent deformation of the mold after the pressure, Mould Making sometimes the internal pressure can reach 100MPa.

The ejector is an important factor affecting the deformation and dimensional accuracy of the product, so the optimum ejector point should be chosen so that the stripping is uniform. High-precision injection mold in the structure of the majority of mosaic or full-fight structure, Mould Making which requires mold parts processing accuracy, interchangeability are greatly improved.

Mold experts Luo Baihui that, Mould Making for injection molded parts, mostly with other parts supporting the complete composition of the product, and in many cases are completed in other parts, Mould Making eager to wait for injection molding of the supporting listing.Mould Making Because the shape of the product or the size of the requirements of high precision, coupled with the characteristics of the resin material is different, mold manufacturing is completed, but also need to repeatedly test mode and correction, so that development and delivery time is very tight.

Mold manufacturing is not the ultimate goal, Mould Making but by the user put forward the final product design, mold manufacturers according to the user's request, Mould Making design and manufacture of molds and in most cases, the production of products is also in other manufacturers. Mould Making This resulted in the design of the product, the design and manufacture of the mold and the production of the products in different places.

Mold production of small quantities, Mould Making generally belong to the production of single pieces, but the mold needs a lot of standard parts, large to mold, small thimble, Mould Making which can not and can not only be completed by a single manufacturer, and the manufacturing process is complex, Mould Making general equipment and CNC Equipment is extremely uneven.
