Enjeksiyon kal\u0131b\u0131<\/a>ing is a manufacturing process that produces parts from plastic raw materials. Injection molded products are used in a wide variety of industries, including automotive, medical, and consumer products.<\/p>\n

A common problem that can occur during injection molding is dimensional instability. In this blog post, we will discuss some important tips for resolving dimensional instability in injection molded parts.<\/p>\n

When injection molding, the process parameters such as temperature, pressure, and time must be controlled strictly according to the process requirements, especially the molding cycle of each plastic part must be consistent, not arbitrary changes.<\/p>\n

Enjeksiyon bas\u0131nc\u0131 \u00e7ok d\u00fc\u015f\u00fckse, bekletme s\u00fcresi \u00e7ok k\u0131saysa, kal\u0131p s\u0131cakl\u0131\u011f\u0131 \u00e7ok d\u00fc\u015f\u00fck veya d\u00fczensizse, namlu ve noz\u00fcldeki s\u0131cakl\u0131k \u00e7ok y\u00fcksekse ve plastik par\u00e7an\u0131n so\u011futulmas\u0131 yeterli de\u011filse, plastik par\u00e7an\u0131n dengesiz boyutuna yol a\u00e7acakt\u0131r.<\/p>\n

In general, the use of higher injection pressure and injection speed, appropriately extending the mold filling and holding time, and improving the mold temperature and material temperature is conducive to overcoming the size instability failure.<\/p>\n

Kal\u0131planan par\u00e7an\u0131n boyutu gerekli boyuttan daha b\u00fcy\u00fckse, enjeksiyon bas\u0131nc\u0131 ve eriyik s\u0131cakl\u0131\u011f\u0131 d\u00fc\u015f\u00fcr\u00fclmeli, kal\u0131p s\u0131cakl\u0131\u011f\u0131 art\u0131r\u0131lmal\u0131, kal\u0131p doldurma s\u00fcresi k\u0131salt\u0131lmal\u0131 ve kal\u0131planan par\u00e7an\u0131n b\u00fcz\u00fclme oran\u0131n\u0131 art\u0131rmak i\u00e7in kap\u0131 kesit alan\u0131 azalt\u0131lmal\u0131d\u0131r.

It is worth noting that the change in ambient temperature also has a certain influence on the fluctuation of molding size of plastic parts, and the process temperature of equipment and mold injection should be adjusted timely according to the change in the external environment.<\/p>\n

Genel olarak, kal\u0131plama malzemelerinin b\u00fcz\u00fclme oran\u0131 ne kadar b\u00fcy\u00fck olursa, plastik par\u00e7alar\u0131n boyutsal do\u011frulu\u011funu sa\u011flamak o kadar zor olur.<\/p>\n
