Silicone mold, also known as vacuum mold, refers to the use of the original template, in the vacuum state to make a silicone mold, and in the vacuum state using PU, silicone, nylon ABS and other materials for pouring, so as to clone the same copy with the original template, the reduction rate of 99.8%.
Silicone mold production cost is low, no open mold, short production cycle, service life of about 15-25 times, suitable for small batch customization. So what does a silicone replica look like? What are the applications and characteristics? Let's take a look.
Silicone remolding process
Silicone mold material: ABS, PC, PP, PMMA, PVC, rubber, high temperature material and other materials.
1, manufacturing prototypes: according to the 3D drawings provided by customers, through CNC machining, SLA laser rapid prototyping or 3D printing to produce prototypes.
2, pouring silicone mold: After manufacturing the prototype, manufacturing mold frame, fixed prototype, pouring silicone, 8 hours after drying, open the mold to take out the prototype, silicone mold manufacturing is completed.
3, injection type: the liquid plastic material is injected into the silicone mold, and after 30-60 minutes of curing in the incubator of 60°-70°, the mold can be released, and if necessary, the secondary curing is carried out in the incubator of 70°-80° for 2-3 hours. Under normal circumstances, the service life of the silicone mold is 15-20 times.
What are the applications of silicone mold?
1, plastic hand board: the raw material is plastic, mainly some plastic products, such as TV sets, monitors, telephones and so on. The most common photosensitive resin in 3D hand proofing is a plastic hand proofing class.
2, silicone coated hand board: its raw material is silicone, mainly to display product design shape of the hand board, such as cars, mobile phones, toys, crafts, daily necessities and so on.
The advantages and characteristics of silicone compound mold
1, silicone mold has the following advantages:
1) Low production cost. The processing cost is also much lower than CNC machining and 3D printing;
2) Short production cycle. Save the time of mold opening, greatly provide production efficiency;
3) Do not open the mold. Save the time of mold opening, win valuable time for customers to develop new products, seize the market standby;
4) High degree of reduction, small probability of processing failure;
5) Suitable for small batch production, short customization time, low cost;
6) Exquisite workmanship, no rough edges.
2, the advantages of vacuum mold compared with other hand plate process has its advantages, with the following characteristics: free mold, low processing cost, short production cycle, high degree of imitation, suitable for small batch production and other characteristics. Favored by the high-tech industry, silicone mold can speed up the research and development progress and avoid unnecessary waste of funds and time costs during research and development.
3, the characteristics of small batch silicone compound mold hand plate
1) Silicone mold does not deform, does not shrink; High temperature resistance, can be used repeatedly after mold forming; Provide convenience for product imitation;
2) The silicone mold is cheap, the manufacturing cycle is short, and the unnecessary loss can be prevented before the mold opening.
