We usually think that how critical are material considerations when designing a mold. Actually you should make sure that molds are designed with the maximum processing window to allow flexibility and room for increased efficiency in manufacturing. Like in case of high shear conditions that are present with smaller gates may restrict the molder when it comes time to make operations more efficient. The smaller gates may improve efficiencies with crystalline materials through shear thinning, taking the same approach with amorphous acrylic materials may simply lead to degradation and surface defects Displays inherent rigidity and strength of acrylic thus allowing the design of a thinner part than with other transparent plastics. Because of this it allows the end user to use less material. Some other consideration is the physical strength. The sensitivity of acrylics regarding notch means that parts should not be designed with notches. it can be over come to some extent with the use of impact-modified acrylics. Because of the high optical quality of acrylic it amplifies the importance of a mold's surface polish and detail characteristics since acrylic transmits more light than any other material.

Acrylic compounds are advancing very vastly. In the next five years the key areas that acrylics are focused will be optical media storage, such as DVDs. Initially acrylics were used in laser discs because of the high transparency and low optical distortion of the product. The basic properties of acrylic, such as naturally superior transmittance and extremely low optical distortion, mean that current limitations of optical storage capacity could be exceeded and at a lower cost than currently used materials. In attendance are certain chemicals with special characteristics commonly known as acryl group? As of these, acryl fibers are made that contain 85% acrylonitrilemonomer. And from this various kinds of acrylic products are created like blankets, plastics, sweaters and various other daily use objects. The acrylic is lightweight, soft, and warm, with a wool-like feel. It dyes very well and has excellent color-fastness and it is resilient, retains its shape, and resists shrinkage and wrinkles, it is quite varied in form and sometimes has an appearance similar to wool or cotton. The fiber has recently been used in clothing, as a cheaper alternative to cashmere, due to the similar feeling of the materials, and the disadvantages of acrylic are that it tends to fuzz (or pill) easily and that it does not insulate the wearer as well as cashmere. Numerous products like fake pashmina or cashmina use this material to create the illusion of cashmere to the consumer. This fiber is resistant to moths, oils, and chemicals, and is very resistant to deterioration from sunlight exposure. So, static and pilling can be a problem.
