What's the best progress for making a small QTY of plastic parts?
Perhaps a lot of people want to know what's the best progress for making a small quantity of plastic parts?The answers will be different,such as CNC machining,3D printing or prototype mold.
Today,Deep Mould will provide you the forth solution:Silicone mold which also called vacuum casting.
Silicone mold, also known as vacuum mold, refers to using the original template to make a silicone mold in a vacuum state, and pouring it with PU, silicone, nylon ABS and other materials in a vacuum state, so as to clone the original model. The replica of the same model, the restoration rate reaches 99.8%.
The production cost of the silicone complex mold is low, the mold opening is free, the production cycle is short, and the service life is about 15-25 times. It is suitable for small batch customization. So what is the silicone mold? What are the applications and features? Let's take a look below.
1>Silicone molding process
Silicone composite mold materials include: ABS, PC, PP, PMMA, PVC, rubber, high temperature resistant materials and other materials.
1. Prototype manufacturing: According to the 3D drawings provided by customers, prototypes are manufactured by CNC machining, SLA laser rapid prototyping or 3D printing.
2. Pouring the silicone mold: After the prototype is manufactured, the mold base is made, the prototype is fixed, and the silicone is poured. After 8 hours of drying, the mold is opened to take out the prototype, and the silicone mold is completed.
3. Injection molding: inject the liquid plastic material into the silicone mold, cure it for 30-60 minutes in an incubator at 60°-70°, and then release the mold, if necessary, in an incubator at 70°-80° A secondary cure of 2-3 hours is carried out. Under normal circumstances, the service life of the silicone mold is 15-20 times.
2>What are the applications of silicone molds?
1. Plastic rapid prototype: The parts' raw material is made by plastic, such as televisions, monitors, telephones and so on.
2. Silicone prototype: The mold's material is silicone,this kind of mold has advantages of fast lead time and cheap cost. It mainly used to display the outside covers, such as automobiles, mobile phones, toys, handicrafts, daily necessities and so on.
3>The advantages and Features of Silicone mold.
1. Silicone compound mold has the following advantages:
1)The production cost is low. Mostly the silicone mold can make 5-15pcs each mold.In this way,the unit cost is lower than CNC machining and 3D printing service;
2)The production cycle is short than the steel injection mold. Normally it take 7-10 days for the lead time.It can save time for mold developement and greatly improve production efficiency;
3)Free mold development. Save the time for mold opening, gain valuable time for customers to develop new products, and seize the market standby;
4) The reduction degree is high, and the probability of processing failure is small;
5) Suitable for small batch production, short customization time and low cost;
6) Exquisite and meticulous workmanship, no burrs.
2. The advantages of vacuum casting progress have its advantages compared with other hand crafts, and have the following characteristics: no need to open moulds, low processing cost, short production cycle, high simulation degree, suitable for small batch production and other characteristics. Favored by the high-tech industry, the silicone compound mold can speed up the research and development progress and avoid unnecessary waste of funds and time costs during the research and development period.
3. The characteristics of small batches of silicone complex moulding prototypes
1) The silicone mold does not deform or shrink; it is resistant to high temperature and can be used repeatedly after molding; it provides convenience for product imitation;
2) Silicone molds are cheap and have a short manufacturing cycle, which can prevent unnecessary loss before opening the mold.
Deep Mould is specialized in making the silicone molds for vaccum casting progress. We can make it according an idea from our customers and then make it with a real sample.We could make your parts from an concept to the mass production.
