Surface treatment and assembly cavity  a) When to burnish cavity? The process of polishing, polishing equipment and the attention to polish? b) When to create rough cavity? Methods textured? c) Assemble mold: Process assembly?  To achieve high quality polish to note the following factors:   Polished high velocity (generally the higher the better);  Polished genuine material (diamond powder, caborundum, alumina ) and fit (with material needs polishing);  Polishing reasonable pressure;  Polishing appropriate instrument (this step primarily to correspond to step and and to high yield)  If you choose the correct size, the abrasive particles after the first polishing, size undulating be leveled down to half the original, use particle size by half while polishing rough to lower the undulating size to / etc until the mirror  Select the size abrasive particle size undulating  2 The next time choose grinding grain size 1/2 times before To clarify matters, we see illustration below:   If the surface is scratched many stone hit 600 before (member red, stones hand) for both hands and then increase the size rock on 1000, 1200 Once typed in by hand finished, hit all kinds sandpaper hands Felt + finished, beaten with cream polish it light up   Surface smoothness of the mold can be achieved after the polishing process depends on the following factors:  - The quality of steel mold  - Thermal molding process  - Engineering polish Polish  Polishing techniques to suit each different type of steel Know when to stop polishing the undulating were properly eliminated The hardness of the steel, the higher the grinding them very difficult These issues should be considered when polishing mold   -The polished mold nên print done little dusty and places where nên isolated  - Polishing tools used for each khác nên type of particle polishing and nên stored in the secret place  - When polished finish, the polish needs to follow directions  - We shouldnt start printing places with angular shape polishing The polishing process typical mold  - Choose a certain particle size and hard polishing tool and then select the instrument under decreasing stiffness - Select tool polishing medium hardness and coarse grains, then choose the particle size decreasing  f) The method of polishing metal processing   - Polish with marbles, natural stone materials, artificial grinding tools with chemicals  - Polish with sandpaper in combination with chemotherapy  - Polish with metal tassels  - Method polished terrazzo Things to note during grinding mold   The process of grinding is not generating more heat and pressure, as they will affect the structure of the surface and the hardness of steel Therefore when grinding mold, should take reasonable measures heat  - Use the grinding instruments must be clean, and use soft abrasives for hard steel surfaces  - When changing the particle size of various grinding must be cleaned to avoid the details of the abrasive grinding marks another cause scratches on the surface of the product -Create PRODUCT rough surface   Tạo nhám bề mặt EDM  -Create PRODUCT rough surface  Tạo nhám bề mặt máy phun cát  1- Sản xuất tivi  ( Audio - visual electronic appliance )  2- Sản xuất điện thoại   ( Telecommunicating equipments )  3- Sản xuất máy tính  ( Computer peripheral )  4- Sản xuất dụng cụ gia đình  ( Domestic items )  - Tất sản phẩm nhựa khác  5.5.2 Process mold assembly   Step 1: Enter  on bare boards  on the model  Select the type of installation is  Default Bước 2:   Lắp bạc dẫn hướng vào khuôn Bước 3:  Lắp kẹp với khuôn Bước 4:  Lắp bạc cuống phun vào kẹp lắp bulông để giữ 2tấm khuôn vớinhau Bước 5:  Lắp vòng định vị với kẹp vm2 bu lông giữ vòng định vị Như vậy, lắp xong phầnkhuôn cố định Bước 6: Lắp chốt dẫn hướngvào khuôndưới Step 5: Insert the positioning of the plate clamp ring and two bolts on the vi.Nhu giuvong such, has assembled fixed part mold  Step 6: Lapchot led huongvao khuonduoi plate Step 7: Laptam pushed in (if used tyday, mounted on panels giucung tyday time when lapchot recovery) Bước 8: Lắp lò xo  gốiđỡ Bước 9: Lắp giữ 4chốt hồi Step 10: Install the bolts push  full and and inter kettam tamgiu Step 11: Insert clamping plates and bolts on the link part khuondi [...]... installation is  Default Bước 2:   Lắp bạc dẫn hướng vào tấm khuôn trên Bước 3:  Lắp tấm kẹp trên với khuôn trên Bước 4:  Lắp bạc cuống phun vào tấm kẹp trên và lắp 4 bulông để giữ 2tấm khuôn vớinhau Bước 5:  Lắp vòng định vị với tấm kẹp trên vm2 bu lông giữ vòng định vị Như vậy, đã lắp xong phầnkhuôn cố định Bước 6: Lắp chốt dẫn hướngvào tấm khuôndưới Step 5: Insert the positioning of the plate... various grinding must be cleaned to avoid the details of the abrasive grinding marks another cause scratches on the surface of the product -Create PRODUCT rough surface   Tạo nhám bề mặt bằng EDM  -Create PRODUCT rough surface  Tạo nhám bề mặt bằng máy phun cát  1- Sản xuất tivi  ( Audio - visual electronic appliance )  2- Sản xuất điện thoại   ( Telecommunicating equipments )  3- Sản xuất
