1, the mold should be thoroughly cleaned and refurbished before use. After the refurbishment is needed, the coating resin will be painted, the polyester film is covered, the coating can be rolled and the surface layer is polished after curing. 2. Use a soft cloth to form a layer of high temperature resistant wax on the surface of the mold, and polish it as dry as a mirror. 3, in the wax mold surface, paint a layer of demoulding agent, smear release agent should pay attention to uniform painting, never leak, otherwise affect the quality of products, and even cause waste. 4. After thoroughly drying the mold release agent, the surface layer resin (product gel coat) is used to brush the mold, and the surface layer is made of the surface layer, the surface layer is the adhesive resin, and any kind of adhesive coating decoration type high temperature resistant resin can be used. 5. Mixing S - 793 high temperature resistant polyresin with 4 - 8% curing agent and adding 3 - 6% accelerators to stir well (low temperature accelerant addition, low temperature accelerant adding), the mixed slurry is injected into the mold, a little vibration, vacuum removal of gas bubble, and after static for about 30 minutes, the raw material will be fixed naturally. After heat treatment, remove the negative mold, release the heat in the mold, and then remove the mold after the product is completely cured. 6. Remove the waste products from the mold, remove the release agent from the water, and polish it into the packaging.
