In order to obtain the high quality of the polishing effect, the most important is to have a plastic mold for the high quality of oilstone, sandpaper and diamond grinding paste polishing tool and auxiliary products. The choice of the polishing program depends on the surface conditions of the machining, such as machining, EDM, grinding, etc.. So it is essential to understand the basic program of plastic mold parts polishing..
the basic program of plastic mold parts polishing are as follows:
1, the fine cast

The main use of diamond grinding paste. If buffing the mixture of diamond abrasive powder or grinding paste grinding, the usual order of the grinding is 9 m #1800 ~ 6 m #3000 3 mu m #8000. 9 m diamond grinding paste and polishing cloth can be used to remove hair worn #1200 and #1500 sandpaper left. Then, the polishing paste was polished with a paste felt and diamond abrasive, the order of 1 m (#14000) ~ 1/2 m (#60000) m ~1/4 (#100000). The accuracy is required at 1 m (including 1 m) of the polishing process in the mold processing workshop a clean room can be carried out. For more precision polishing, a clean room is required.. Dust, smoke, high precision polishing the surface of dandruff and foam can be scrapped slobber hours after work.
2, rough throw
After milling, EDM, grinding and other processes, the surface can choose the rotational speed of 35000 - 40000 rpm or a polishing machine or an ultrasonic polishing machine. The commonly used method has the diameter of 3mm, WA # 400 wheels removing white electric spark layer. Then the manual grinding stoneprocessing, strip stone plus kerosene as lubricants or coolants. General use of the order of #240 ~ #180 ~ #320 ~ #400 ~ #600 ~ ~ #800 ~ #1000. Many die manufacturers choose to save time from #400.
3. Semi precision throw
Semi fine polishing mainly use sandpaper and kerosene. The number of paper are as follows: #400 ~ #600 ~ #800 ~ #1000 ~ #1200 ~ #1500. In fact sandpaper only #1500 for hardened die steel (52hrc above), and is not suitable for pre hardened steel, because it may lead to pre hardened steel surface burn.
4.The fine polishing
With the abrasive cream to throw, 800010000 to reach the mirror.
Needle punch, punch, guide columns, a guide sleeve, a top rod, a thimble, Secretary extinguishers, steel ball sets, independent guide column, a slide block, a date stamp, inclined top slider, intersection set, positioning block, guide bit fixed block, a guide column aid (pillar location), guide column assembly.
Through the above, you must have some knowledge of the basic program of plastic mold parts polishing.. If you want to know more you can go to Dongguan Yi Ze Mold Co., Ltd. for a more detailed understanding of the  plastic mold parts polishing.
