Culture stone Culture stone plastic mold plastic mold characteristics: ① culture stone mold plastic to have a good performance. ② culture stone plastic mold better flowability, low viscosity, easy to operate. ③ culture stone plastic mold shrinkage as possible. ④ cultural stone mold plastic tension better. ⑤ cultural stone mold made out of plastic can not be deformed. ⑥ culture stone mold rubber hardness to be suitable for production use. ⑦ temperature, turn mode more often, life is longer, acid and alkali resistance, aging resistance. Plastic mold manufacturing method of a culture stone, plastic bowl filled with a 500g plastic reinforcement agent at room temperature for 1.5%, stir evenly spare. 2, the mother mold release agent treated blanks with lubrication. 3, lubrication good mother surrounded by green wood surround, wood releasing treatment is also applied in the middle of the gap to 2-4cm is appropriate. 4, along with a good glue slowly pouring a fixed perfusion point, not when the shock to exclude the air inside. 5,60 minutes Chung completely cured after four weeks and then glue strips of wood surrounded, leaving 4cm gap, dismantle wood strips. 6, after the injection of gypsum powder 1000g watered wooden box, filled up (use plastic piece of wood box divided into two parts in order to facilitate the form removal). After removal of 7,20 minutes Chung wooden molds that do complete. Culture stone mold plastic Note: 1, should increase the amount of curing agent depending on temperature, high temperature decreased. Excess curing agent, the mold will be hard and brittle; curing agent is too small, the operating time is extended. 2, in order to prevent mold silicone material changes, we recommend without silicone oil. 3, in order to mold you can achieve the best results, please die storage at least 24 hours after use. 4 die can also be made of resin. Operation culture stone plastic mold: 1, culture stone mold plastic mold and curing agent Stir liquid silicone exterior is flowing, A component is silicone, component B is the curing agent. Example: Take 100 g silica gel, 2 g of curing agent (Note: silicone and hardener must stir, stir if not, there will be a mold has been cured, a no curing, drying and curing silicone will appear uneven The situation will affect the silicone mold life and turning model number, even resulting in mold scrapped condition 2, vacuum row bubble treatment: After silicone curing agent Stir evacuated rows of bubbles links, vacuum The time should not be too long, under normal circumstances, not more than ten Chung, vacuum too long, silicone cured immediately, resulting in a cross-linking reflect that becomes a piece of silicone can not be painted or perfusion, thus waste of silicone, the silicone into the trash can, do re-take the silicone 3, brushing or procedure: The row over the bubble of silicone evacuated to brushing or perfusion way back in. products above (Note: The product or model to be replicated before the fall is absolutely necessary silicone release agent or release agent) then put silicone products above brushing, brushing must be uniform, after 30 minutes Chung paste one. layer gauze fiber silicone sheeting to increase the intensity and tension. then brushing a layer of silicone, then paste a layer of gauze fiber sheeting, so twice after it. Only by doing so, open up the silicone mold life and turning model to improve the lot number of a relative, you can save costs, improve efficiency 4, the outer mold making: General methods and materials used is to mold around with a plastic sheet or boarded up, a plaster mold the cabinet filled it, another way of using resin brushing, brushing a layer of resin on a layer of fiberglass cloth paste, paste and then painted again, repeated two or three can be done outside the mold of the mold. 5, irrigation Operation mode or perfusion modes: filling the mold or perfusion mode, is used to compare smooth or simple product, there is no parting line saving time and labor, that is, the product or model you want to copy, enclosed with a plastic sheet or glass the smoked vacuum silicone directly into the products above, to be molded silicone dry, remove the product, mold on the shape (Note: perfusion mode generally used to do the hardness of the softer silicone mold, so stripping easier does not damage the silicone mold inside the product).
