About the whole process of silicone mold forming
Silica gel mold is usually used in the production of small batch samples of hand plate. The biggest advantage of silica gel mold production is fast, which can very well reduce the research and development cycle. The experimental process of product development will use the silica gel mold to come out of the shell of 10 to 100 sets of products in small batches. And will do the product performance test (waterproof, anti-static, sunscreen, anti-salt spray, anti-aging and other stable function test).
What is the difference between silica gel mold and mass production steel mold?
Silicone mold and practical experiment validation prior to mass production purposes, such as industrial design scheme, the early stage of the design of industrial product data structure of frozen test, quantity of prenatal die out before the die structure of precision products to investigate whether qualified, etc., all need early to do a batch of silicone mold copy and perfusion product out initial validation. The role of steel mold is in large quantities, such as a product needs one hundred thousand, one million pieces of steel mold injection production.
How is the silicone mold produced?
Industrial people to share with you the production process of silica gel mold, the molding of silica gel mold is to use an industrial design product plan, which is usually said to be 3D data, also called 3D map. One of the manufacturing processes of industrial people is to output 3D data to 3D printing or CNC equipment using professional engineering programs for processing. The 3D printed data is processed on the 3D printer or CNC machining center machine to produce a prototype exactly the same as the 3D data. This prototype is also called sample, or "sample", commonly known as "proofing" link. After the first sample is made, skilled manual masters should be used to refine the prototype. Quality inspection should check the prototype and 3D data, so that the original and data are fully consistent, which is a link before the completion of the silicone mold.
The next step is to do the silicone mold process!
With a bottom plate to prototype with two to three wooden round rod, prototype generally support suspended 20 to 50 mm, the periphery of the prototype with yellow tape sealed, do not look down on the yellow tape, his role can be great, it is the follow-up mold parting line. Once we've staked out the prototype and sealed the yellow tape, we're going to start wrapping the prototype with wood or plastic, watch out! Allow 20-50 mm of space around the prototype. Surrounded by wood, the periphery of the prototype and then do some fixed support, so that the silica gel mold is well shaped, so that the whole mold frame is formed. After completion, pour liquid silica gel into the prototype, cover the prototype 20-50 mm high, vacuum suction with a vacuum injection machine, clean the air in the mold, and then move the mold into a high temperature oven to bake for 2 hours, after baking, manual mold opening, this time the role of yellow tape will come out. According to the position of the yellow tape, the mold is divided with a special tool, the silica gel mold is cut in half, and the prototype of the silica gel mold is taken out, so that the silica gel mold is formed! Follow-up work is small batch copy products, silicone mold and products are made in this way, want to know more then contact industrial rapid prototyping!
