1, environmental conditions. Temperature: should always keep the same environmental temperature in the manufacturing process of male and female mold, which is 21 to 28 DEG C. Humidity: relative humidity on the gel coat resin curing and great influence, the ideal humidity range from 40 to 60, if the relative humidity is more than 65 mold manufacturing, should wait to the appropriate conditions of production and construction, especially in the South and coastal areas, the humidity is relatively large, should be careful.
2 clean workshop. In a dirty environment is incapable of producing high quality molds, mold manufacturing, Yin area should be highly clean, must be larger than the production area products have higher management standards, so, at the beginning of manufacturing mold, dust removing and cleaning work should be well ahead of time mold manufacturing area.
3. Clean compressed air. Pure, dry gas supply is another element in the manufacture of high-quality molds. If the wind pipe in the air with a small amount of water or oil, then there will be a lot of mould gel coat surface pinholes and pits, so to pay a lot of labor to repair, so that the mold quality will be greatly affected. The air compressor needs to be housed in a good environment and equipped with an effective air dryer and an oil-water separator.
4. Selection of raw and auxiliary materials. The selection of high quality raw and auxiliary materials is an important condition for the manufacture of high quality moulds. The cost of raw and auxiliary materials used in the manufacture of moulds is a small percentage of the total cost and can not be used to save the product, resin or materials already in storage and inferior materials.
5. Reasonable molding time. Scheduling appropriate tooling schedules is one of the factors in making good dies. Whether it is the use of the traditional method of paving layer, or with low shrinkage in the new system, the demand of the time were determined by these raw materials chemical properties, tried to take a shortcut or accelerate the process, will have a bad effect on the quality of the mold.
