The use of acrylic materials for plastic injection molding is on the rise. These polymers offer excellent properties in various aspects including mechanical, chemical, thermal, electrical, and optical resistance.
Acrylic materials can be merged with a number of substrates through thermal and chemical processes, for acrylic injection molding. An added benefit of these materials is that they are biocompatible. As a result, when subjected to gamma irradiation, they can be formulated to retain their excellent clarity. Besides, high optical transmittance is another aspect adding to the popularity.
The parts manufactured from acrylic materials are not only cheap, but also offer excellent performance. Hence, they are highly preferred for the production of disposable medical devices as well as other items such as house ware.
Meeting Stringent Requirements
Using the acrylic injection molding process for product manufacturing can help meet stringent requirements for a vast range of applications. Especially, medical items that are complex in structure and present challenges for traditional injection molding. When manufacturing such devices, suitable acrylic polymer grades are used, and the acrylic injection molding parameters are also selected carefully. Following are some of the crucial parameters to consider:
- High thermal & chemical stability
- High optical transmittance
- Range of products and uses
- All forms of Acrylic molding
Exceptional Chemical and Physical Properties
Apart from medical devices, house ware, and lighting equipment are other generally produced items with acrylic injection molding. Acrylic materials have high light transmittance, over 90 percent. This makes it comparable to glass of optical quality. Thus, optically clear plastics produced by acrylic injection molding can successfully withstand exposure to ultraviolet radiation. Especially, when they are exposed to light it does not result to discoloration or fading.
Because acrylics have no odor or taste, acrylic injection molding is widely used to manufacture different food storage containers and refrigerator drawers. The properties of acrylics can be changed when copolymerization is affected. ABS is added to acrylics to obtain higher impact strength. Apart from that, polycarbonate is added, to obtained impact strength higher than that of sheer polycarbonate. Although, it results in reduction of ambient temperature the impact strength of both acrylics and their copolymers.
It is always recommended to speak to the manufacturer in regards to acrylic molding. They are best people who can help you source the perfect service as per your needs.
