Silicon molding services produce molded components made from silicon. Silicone rubber is a two-component, synthetic, flexible rubber like material made from silicone

According to USFDA, a combination product is one composed of any combination of a drug and device; biological product and device; drug and biological product

elastomers that can be cured at room temperature into a solid elastomer used in molding. It is heat resistant, durable and free of allergens or leachable chemicals.

Laser cutting is a modern technology in which a high-powered laser is directed at the desired surface to cut different shapes and forms. The material usually burns or melts, leaving a high-quality surface finish. Since there is no direct contact between the laser and the surface in use, the level of precision and accuracy in the laser cutting process is much more as compared to conventional methods.

So you want to go paperless? Not sure where to start? The answer is literally right under your nose. If you have plans to eliminate or reduce your business’s paper consumption and records storage, the best place to start looking is on your desk. The typical desk is loaded with paper - mail, file folders, notebooks – you name it. Chances are the paper that is filling your file cabinet, the file room or the third floor – whatever the case may be – passed over your desk or the desks of your colleagues.

Laser cutting is a technology that uses a laser in cutting different kinds of materials, mostly metals such as carbon steel, aluminum, stainless steel and copper alloys. It is widely used in the metal fabrication industry to increase cutting speed and cutting capacity, reduce production costs, increase productivity and improve cutting quality.
