Ordinary display racks are just some finished wood products or finished products of glass and plastics. In some stores, the ones that appear in the store are not elegant. Although it is not too careless to buy items, if they adopt the acrylic display rack, they can The emergence rate of large growth items can make one or more items appear in front of the purchaser, which can greatly increase the reputation and customer's desire to purchase.

The acrylic product processing display frame has the same result as the traditional acrylic. The reason why it is used to display the item is that it can make the item double the image, and one can be summarized: growth absorption. At the same time, its exposure is much higher than that of ordinary glass, which is impossible to compare with ordinary display frames.

1. Acrylic contains a polar side methyl group, which has obvious hygroscopicity. The water absorption rate is generally 0.3%-0.4%. It must be dried before molding. The drying condition is drying at 80°C-85°C for 4-5h.
2. Acrylic has obvious non-Newtonian fluid properties in the temperature range of molding processing. The melt viscosity decreases with the increase of shear rate, and the melt viscosity is also sensitive to temperature changes. Therefore, for the molding process of acrylic, increasing the molding pressure and temperature can significantly reduce the melt viscosity and achieve better fluidity.
3. Acrylic begins to flow at a temperature of about 160 ° C, and the temperature at which decomposition begins is higher than 270 ° C, with a wide processing temperature range.
4. Acrylic melt viscosity is higher, the cooling rate is faster, and the product is easy to generate internal stress. Therefore, the process conditions are strictly controlled during molding, and post-treatment is also required after the product is formed.
5, Acrylic is an amorphous polymer, the shrinkage rate and its range of variation are small, generally about 0.5% -0.8%, which is conducive to the formation of plastic parts with higher dimensional accuracy.
6. Acrylic cutting performance is very good, and its profiles can be easily machined to various required sizes.
