Solutions

In view of the rebirth of Russian industry and especially the branches which do not require production of big sets of plastic parts but rather they need the production of small quantities of a great number of different parts. How to avoid making a vast number of different molds assuming that all of them are supposed to have parts precisely repeating each other? Dialog Engineering offers sectional molds as a solution to the problem. Sectional mold consists of a universal platform and mutually replacable shaping sections which lets to start the production of new items within short time frames and with minimum efforts and hence investments. It lets to get rid of the necessity to develop an absolutely new mold. The only thing to do is a section replacement which cost is significantly lower along with the lead-time.

Sectional mold allow casting in full automatic mode and with the aid of hot runner system if necessary.

Depending on construction/technology requirements sectional mold allows to decrease:

• development time for 60-70%
• labour-output ration for 50-60%
• steel intensity 3-5 times

We'd like to note that sectional was invented in cooperation with our colleague Mr. Panteleev and was later widely introduced in industry and effectively used at a vast number of plants all across the territory of former USSR. For instance the Grodno plant was manufacturing more than 100 items using 3 platforms only within 1985-1990 timeframe.

We are also ready to design customized blocks for the specific group of products to attain the utmost effect on mold exploitation for manufacturing this group of items.

Having more than 35 years of experience and exploitation of group mold we can announce highest importance of using universal blocks at any production facility where injection molding machines are used.

Nowadays we offer times more advanced molds equipped with modern components but we reckoned important to deliver some succesfull facts from the history.

We'd also like to note that Dialog Engineering is not only reviving sectional molds in Russia for their wide usage but is also ready to supply multi-layer molds with hot or cold runner system.

As an example of sectional mold we'd list several sections for the block with automatic uncrewing of a screw core pin (fig.1)

fig. 1

Fig. 2 shows a section for this block where one screw core pin is supposed to be unscrewed in automatic mode inside the block and another one is extraced together with the item and unscrewed outside the block manually or with the aid of simple tool for unscrewing screw pins.
