Operations of molding silicone
If the customer wants to make large products and large size molds, the mold should be made ofmolding silicone with high hardness. On the contrary, if the mold with fine and precision patterns, it should be made of silicon with low hardness. The amount of the curing agent depends on the actual requirements of the customer.

Tin-based silicones, also called condensation-cure silicones, are two-component materials which cure at room temperature(RTV)to flexible, high tear-strength rubbers. Tin cured silicones can be poured onto models or they can be made brushable by adding a thixotropic additive. They are ideal for molds where easy release or high temperature resistance is required. Tin cured silicones can be used for casting polyurethane, epoxy and polyester resins, waxes, all gypsum products and low-temperature metals. Our tin-cured silicone systems are the most economical. They are best used for casting resins and low melt metals.

The choosing of suitable hardness should be according to the size and pattern design of the products. If large products and therefore multiple-piece molds are needed by customers, silicone rubber with higher hardness will be required for the molds. Conversely, soft silicon is indispensable for molds with complicated pattern and delicate details. The amount of curing agent admixture depends on the actual need of customers. More will be added for speedy drying and fast release and less when otherwise. 3.

Manual molding silicone rubber is mainly used for model design of manual mold, pvc plastic molds, cement products, low melting point alloy molds, alloy toys, plastic toys, handicrafts, stationery, large-scale sculpture, reproduction of cultural relic, shoe sole molds, pad printing allocation, electronic equipment antivibration, etc. 25kg/drum and 200kg/drum
Shoe mold silicone rubber A. Mainly used for shoe soles mold making B. Two-component silicone rubber with tin-catalyst C. Cured under room temperature D. Low shrinkage E. Excellent fexibility & easy demould Shoe mold silicone rubber applications Shoe mold silicone rubber is mainly used for shoe molds, sand casting, sole sampling, plaster models, simple products, products with non-complex patterns, as well as product models with stable size and non-deformation. Shoe mold silicone rubber features: A.Two-component silicone rubber with tin-catalyst B.Cured under room temperature C.Low shrinkage D.Excellent fexibility & easy demould Shoe mold silicone rubber using instruction: The component a of shoe mold silicone rubber is white flowing liquid and the component b is the curing agent. For example, take silicone rubber of 100g and add 2% curing agent for mixing evenly. After the silicone rubber and the curing agent are completely mixed, put the silicon into a vacuum machine for deairing to remove the bubbles. After deaired, pouring the liquid silicone rubber into the product to be duplicated or into the mold frame. Notes: Shoe mold silicone rubber is used for pouring or brushing technique. That is to say, fix the product or sole model to be duplicated onto a plane plate, then enclose the plane frame with wooden plates to prevent the leakage of the silicon , mix the silicone rubber and the curing agent evenly according to the mixing ratio of 100 : 2 and pour them onto the sole model, then brush evenly with a wooden plate or a brush, and fill up the mold frame with gypsum after the silicone rubber is dried 25kgs/drum vacuum package or 200kgs/drum

100:2 two-component liquid silicone rubber belongs to condensation type mold silicone rubber. When part A and B are mixed in 100:2 weight, the crosslinking reaction can occur, and the elastic body with certain hardness is formed after curing. It has many advantages, such as good fluidity, easy to operate with low viscosity. After curing, it has heat resistance, high temperature resistance, corrosion resistance, solvent resistance, high tensile and tear strength, low linear shrinkage, high turning model times. It is a cast of gypsum, cement, POLY-RESIN, PU, AB water, ABS material of the elastic mold material, it is widely used in the production and reproduction of sludge, toys, gifts, reliefs, statues, city sculpture, cement products, hand plate, car model, model of home appliances, mold products such as soap.

Step 1:preparing mold. Once you have your model to mould you need to build a box from wood/acrylic to contain the silicone and get a good covering over your model , the size and shape of this container is totally depends on shape of the model , remembering to leave plenty room surrounding the model so that you will have a strong wall thickness (at least 20mm) Note:small models can be cast in sourced containers like tins , ice buckets , cake tins, etc
