Abstract
A molding method for protective equipment includes seven steps. A first step is to prepare a mold consisting of an upper and a lower mold respectively provided with a mold hole. A second step is to heat the mold to a preset first temperature. A third step is to place a plastic plate and a foam member in the mold. A fourth step is to move the upper mold nearer to the lower mold, and then close up the upper mold on the lower mold in a preset time for the two materials to melt. A fifth step is to heat the mold to a second temperature higher than the first temperature so that the outer surface of the two materials may melt. A sixth step is to cool the mold to a preset temperature to let the two materials cool to form a shape. The seventh step is to open the mold and take out a finished product.
Claims5
A molding method for protective equipment comprising:
- A first step of preparing a mold consisting of an upper mold and a loser mold, said upper mold having an upper mold hole formed in a center portion, said lower mold having a lower mold hole to correspond to said upper mold hole;
- A second step of heating said mold to a preset first temperature;
- A third step of placing a plastic plate with a preset shape and a foam member with a preset shape in said mold;
- A fourth step of moving slowly said upper mold nearer to said lower mold and then closing up the upper mold on said lower mold in a preset time, forcing said plastic plate and said foam member gradually melt;
- A fifth step of heating said mold closed up to a second temperature, said second temperature being higher than said first temperature to let an outer surface of said plastic plate and said foam member to a molten condition;
- A sixth step of cooling said mold to a preset third temperature, said third temperature being lower than said first and said second one so that said plastic plate and said foam member may be cooled and harden in shape;
- and,
- A seventh step of opening said mold and taking out a finished product.
