Silicone rubber hand plate is a kind of silicone product mainly used for making hand mold. Silicone rubber hand plate series silicone is a kind of flowing liquid. No matter what color it is, its quality is unchanged. Silicone rubber hand plate has low viscosity, good fluidity and easy operation, so it is commonly used to make various silicone models. The main requirements of silicone rubber hand plate are: no shrinkage, no deformation, suitable hardness, and not too complex products.
Silicone rubber hand board is used for making hand board model design, PVC plastic mold, cement product mold, melting point alloy mold, alloy toy process, plastic toy crafts, gift stationery, large statues, cultural relics replication, sole mold manufacturing, pad printing positioning, electronic equipment earthquake resistance, etc. Large products, prototype design, electronic product pad printing positioning, model design, and mold turnover times are about 5-10 times. They are used to make simple pattern products, toys and cars. The main requirements are: no shrinkage, no deformation, and the hardness is suitable for the use of less complex products.
Silicone rubber hand board is a two-component flowing liquid with adjustable color. Component A is a flowing liquid and component B is a curing agent. First, handle the mold seed or the copied product, take a certain amount of colloid, add 2-3% curing agent, stir it evenly, and then use it. The mold can be cured and formed in 2-3 hours. Generally, it will be put into production after 24 hours.
Through practice, Jinan handboard manufacturers have come to the conclusion that the methods of opening silicone rubber handboard molds include wrap mold, brush mold (slice mold, three-dimensional mold, plane mold) and pouring mold, which are determined according to the size of products.
1. Mold wrapping: first wrap a layer of soil with a thickness of 3~5mm on the mold seed, make a gypsum coat, remove the soil stains and demoulding seed, pour the mixed silica gel and curing agent into the gypsum coat with mold seed, and cure it.
2. Brush mold: generally, the three-layer brush type is multi-layer according to the mold requirements. One layer of brush is vacuumized on the mold seed and brushed in place. Apply gauze on the second layer. Three layer cover is cured and formed.
3. Pouring mold: pour the evenly stirred silica gel and curing agent into a container surrounded with mold seeds, and vacuum it for curing. In some cases, if the mold seed cannot be taken out directly, it must be demoulded to facilitate smooth production.
