Gesso line mold silicone purposes

Gesso line mold silicone is mainly used in toys, simulation plants and animals sculpture, Buddha carving handicraft product of a variety of industries such as replication and mold production, polly industrial products, mold manufacturing, plaster craft gift industry, gift stationery industry, plastic toy industry, gift industry, handicraft industry, furniture decoration industry, character copy, building decoration industry, resin handicraft industry, unsaturated resin process conduct industry, candles process, plaster waist line, etc.

The characteristics of gesso line mold silicone

1. The tensile strength of the silicone rubber is better.

2. Mold silicone rubber has good operating performance.

3. The silicone rubber hardness to suitable for products.

4. Silicone rubber shrinkage as small as possible.

5. High temperature resistant, rolling over more, the longer service life, the better, resistant to acid and alkali resistant to ageing.

6. Make the silicone mold deformation.

7. Silica gel better mobility, low viscosity easy to operate.

The method of making the gesso line mold silicone

1, with a plastic bowl for 500 g glue, at room temperature curing agent 1.5%, fully stir well. Set aside.

2 cavities, the billet with release agent processing lubrication.

3, lubrication good mother around sticks around, they also used release agent processing, with 2 -- 4 cm in the middle of the gap is advisable.

4, with good glue along a fixed infusion point slowly pouring, not was to eliminate the air inside.

5, 60 minutes after the glue solidified completely around sticks around again, stay 4 cm gap, in addition to the log.

6, the gypsum powder after water injection against 1000 g wood box, fill so far (wood plastic box application is divided into two parts and ripping).

7, 20 minutes after dismantling batten, mold or do.

Gesso line mold silicone operation method

1, silicone and curing agent. The mold silicone appearance is flowing liquid, A component is silica gel, team B is curing agent. Example: take 100 grams of silica gel, add 2 grams of curing agent (note: silicone and curing agent must stir well, if there is no uniform mixing, the mould will be a piece of has solidified, a no cure, silica gel can appear uneven drying curing condition will affect the service life of the die and the silicone mold number, and even cause mold scrapped.

2, vacuum exhaust bubble processing: after silicone and curing agent mix, vacuum exhaust bubble link, vacuumizing time shoulds not be too long, under normal circumstances, not more than ten minutes, vacuum time is too long, [1] silicon rubber curing immediately, the crosslinking, make the silicone piece by piece, cannot besmear to brush or infusions, thus wasting the silica gel, can only put silica gel in the trash, to take silica gel to do again.

3, besmear to brush or operation process: the time bubble of silica gel, by brushing or perfusion. Pour in the product above (note: to replicate before pouring silicone products or model release agent must be hit or isolation agent). Then put the silica gel coating on product, besmear brushs must be uniform, a layer of gauze in firbre cloth paste 30 minutes to increase the strength of the silicone and tension. And coating a layer of silica gel, then a layer of gauze in firbre cloth paste, so after two is ok. Only by doing so, out of the silicone mold service life and mould number relative to improve a lot, can save cost and improve efficiency.

4, external mold production: general methods and materials is to mold all round, with rubber plate or wood, used a plaster will die ark filled is ok, another way of using resin coating, coating a layer of a layer of glass fiber cloth paste resin, stick, besmear again again repeated two or three layer, can complete the die mould.

5, die or perfusion die operation method: filling mould or filling mould, is used to compare smooth or simple products, no save work line to save time, would you want to copy product or model, with plastic board or glass plate that will be a vacuum of silica gel directly into the products above, after being dry silica gel forming, take out the products, mould is molding (note: perfusion model generally adopts the hardness of soft silicone to do die, so release more easily, does not damage the inside of the silicone mold products).

6, shard or mold piece operation method: using smoked vacuum silicone to besmear to brush or perfusion method construction. If you are doing the mold piece or divided using besmear to brush, besmear brushs the you want to copy product or model before besmear to brush a layer of mold release agents or isolation agent, and then put the silica gel coating on product (note: be sure to besmear to brush evenly) waiting for 30 minutes, to stick on the surface of a layer of gauze or glass fiber weft cloth to increase strength, and then after besmear to brush the second silica gel and silica gel dry, to do mold, outer mold can use gesso or resin material.

Gesso line mold silicone matters needing attention

1, the amount of curing agent added should be depending on the temperature, the temperature decreases. Excessive dosage of curing agent, mold can harden brittle; Curing agent used, less operation time will be extended.

2, to prevent mold silicone property changes, suggested that without silicone oil.

3, for your mold can achieve the best effect of use, please put the measurement for at least 24 hours after use.

4, also can use resin production.
