The paper discusses the types of system elements of mold parts. The calculation method of design data tooling which can be used at design of injection mold is offered. This method gives the chance to provide the necessary accuracy of casting. Distinctive feature of the offered method is modification of the formalized shrinkage material description of a molding detail. The offered calculation method of design data tooling allows increasing the accuracy of the received plastic product because are considered: absolute and relative volume shrinkage; relative actual linear shrinkage of material; alleged linear shrinkage

The publication points out at the importance of the simulation in the initiative preparations of the mould part and the form for mould injection of the plastic material in construction design. It highlights the precise material choice and calls attention to defect prevention, which is needed already in the initiation of the individual mould parts construction models and in the correct cooling design of the plastic mould injection, as to ensure balanced mould part cooling and to prevent later deformation and increase in price, as well as to shorten the construction time.

“…The injection process itself is carried out by entering raw materials in the form of chopped plastic through a hopper and the plastic will be heated in a pipe tube. After the plastic melts at a certain temperature, the plastic is pushed out of the tube through a notepad to be injected into the mold [1]. Next, the printed object is allowed to freeze and cool for a while in the mold before the mold is removed and opened to remove the printed object.…”

Injection molding is the process of molding products with various shapes and sizes from plastic materials. The problem that often arises is the presence of product defects due to shrinkage. In this regard, the effect of water cooling on product size shrinkage in the injection molding process of making acetabular cups with polypropylene plastic and metal steel mold materials will be investigated through experimental investigations. The test begins with the manufacture of molds and injection machines, then the PP liquid plastic is injected twice into the mold, the first with cooling and the second without cooling. Both products are compared for depreciation by measurement. Shrinkage analysis is done by measuring the height and diameter of the product which is then compared with the size of the mold, so that final conclusions can be drawn. Measurement of shrinkage on the outside of the product is taken from three directions, namely the height of the X-axis product (dx), the outside diameter of the Y-axis product (dy), and the outside diameter of the Z-axis product (hz). For the inside of the product with a hemispherical shape, the shrinkage measurement is calculated by calculating the volume which can then be found the average radius. The results showed that the average shrinkage of the cooling test on the X axis = 1.224 %, on the Y axis = 1.857 %, on the Z axis = 1.83%, and on the radius r = 0.825 %. The average shrinkage of the test without cooling on the X axis = 1,591 %, on the Y axis = 2,32%, on the Z axis = 2,369 %, and on the radius r = 1,267 %.
