1, silicone piggy bank mold Daquan Zodiac mold: What are the commonly used tips for silicone mold?
1. Number of holes, 2. Guide post, 3. Eccentricity, 4. Arrange, 5. Burr, 6 years old. Permeability! I hope I can help you.
2. What is the material of the model used for silicone mold? Thank you. How should I use it?
Hello, according to our years of experience, the materials of products produced by silica gel molds generally have the following types:
1, silicone. Suitable for sealing rings and washers.
2. rubber. Soft rubber material with adjustable hardness (40-90 degrees) and color (according to PANTONE color number).
3. ABS. General mold materials, among which the most widely used (divided into ordinary grade, flame retardant grade, medical grade, etc.). )
4, POM, PC, PP and other materials, according to your needs to choose.
3, silicone piggy bank mold Daquan Zodiac mold: What are the characteristics of silicone mold?
I seem to have answered this question before. At present, the molds on the market are divided into hard molds and soft molds. Hard molds mainly include resin FRP molds, steel molds and gypsum molds. Soft molds include one-component room temperature vulcanized rubber, pvc and silica gel molds.
Compared with the hard mold, the silicone mold has the characteristics of easy and fine demoulding.
In the soft mold, the cost of silicone mold is high, but the silicone mold is simple, fine (one head can outline clearly), easy to demould, difficult to deform and reusable. For the specific performance index of silicone mold, please refer to the performance index of Dinghao brand mold adhesive produced by top mold silicone factory. One-component vulcanized latex is made of natural latex mixed with some additives, which is low in cost, but it is troublesome to make, easy to deform and short in service life. Pvc mold is also a mold made by adding some additives to pvc resin and boiling at high temperature, which is labor-consuming and time-consuming, and the cost is between vulcanized latex and silica gel. However, the pvc mold is not fine enough to produce high-precision products, and it is not easy to color pvc mold. If the artificial cultural stone factory uses pvc as the mold, there will be the problem of color blooming.
To understand the characteristics of silicone mold, it is nothing more than indecision in the choice of several molds. We can't look at the problem in isolation, we should make a horizontal comparison, make a more practical choice and not waste it.

1. Silicone mold is a special mold adhesive for products. Silica gel is characterized by high temperature resistance, corrosion resistance, strong tear resistance and high fineness, and is a mold for making various handicrafts.
Second,:
1. Wash the master mold, dry it, and smooth it (you can apply a layer of demoulding wax or a release agent again).
2. Put-gram of mold silicone rubber (mold silicone rubber, mold adhesive, silicone rubber and silicone rubber) into the basin for later use;
3. Weigh the curing agent according to the weight ratio (generally 1.5-2.5%), then add it into a container for mixing and fully stir it evenly;
4. Add a certain amount of silica gel thinner according to the situation (especially the layer). Until mixed evenly, usually 3-5 minutes.
5. Mold silicone rubber (mold silicone rubber, mold adhesive, silicone rubber, silicone rubber) reacts with curing agent at room temperature to release low molecular alcohol. In order to get the alcohol molecules out of the colloid, it is necessary to defoam 1-3 minutes under negative pressure. There is no need to use equipment (mainly depending on the operation experience of the modeler)
6, multilayer paint mold, should follow the inner, middle and outer curing at the same time. When the dosage of curing agent is relatively small, the reaction time is prolonged, the reaction is sufficient and the colloid is good, so the dosage of curing agent is less and more. When brushing, wait for the inner layer to dry before brushing the second layer. The operation time is 30-50 minutes, and the demoulding time is 10- 15 hours. The curing time is 24 hours. Pay attention to the second layer and then paint and mold cloth, which can greatly improve the service life of the mold (but glass fiber cloth must not be used, otherwise it will be easy to delaminate and the whole mold will be scrapped)
What are the characteristics of silicone mold?
7. Generally, 10- 15 hours curing is better for the three-dimensional casting mold.
8. After the soft mold is made, gypsum or glass fiber reinforced plastic jacket should be made to support the silicone soft mold. Note: 1. Mold line selection: select the position that does not affect the appearance of the product; Choose the position that is easy to process after grouting; Select the position where the mold itself is easy to disassemble; Select the position where the product is not easy to deform. 2. Never blindly increase the dosage of curing agent in order to catch up with the production schedule, otherwise the service life of silicone mold will be greatly reduced.
The above is some common sense about silicone mold. What are some common sense about silicone mold to share? After reading the silicone piggy bank mold Daquan Zodiac mold, I hope this will help everyone!
