Conditions for manufacturing molds

1. Environmental conditions

Temperature: During the whole process of manufacturing male and female molds, the same ambient temperature should always be maintained, that is, 21~28℃.

Humidity: Humidity has a great influence on the curing of gel coat and resin. The ideal humidity range is 40~60. If the relative humidity exceeds 65 when making the mold, you should wait until the appropriate production conditions before construction, especially in southern and coastal areas, where the humidity is relatively Big, more careful.

2. Clean workshop

It is impossible to manufacture high-quality molds in a dirty environment. The manufacturing area of ​​the male and female molds should be highly clean and must have higher maintenance and management standards than the product production area. Therefore, at the beginning of mold manufacturing, it should be done in advance. Good dust removal and cleaning work in the mold manufacturing area.

3. Clean compressed air

Pure and dry air supply is another element for manufacturing high-quality molds. If there is a small amount of water or oil in the air duct, a large number of pinholes and pits will appear on the surface of the mold gel coat. For this reason, a lot of labor is required to repair, so the quality of the mold will be greatly affected. The air compressor needs to be placed in a good environment and equipped with an effective Ruishiji compressed air dryer and a high-precision compressed air multifunctional filter for water removal, oil removal and dust removal.

4. Selection of raw and auxiliary materials

The selection of high-quality raw and auxiliary materials is an important condition for manufacturing high-quality molds. The cost of raw and auxiliary materials used to manufacture molds only accounts for a small percentage of the total cost, and it is not possible to try to save and use product resins or materials that have expired and inferior materials.

5. Develop a reasonable mold making schedule

Arranging a suitable mold making schedule is one of the factors that make a good mold. Regardless of whether the traditional layup method or the new low-shrinkage system is used, the time required is determined by the chemical properties of these raw and auxiliary materials. Any attempt to take shortcuts or accelerate the process will adversely affect the quality of the mold. .
