CNC Routing and Cutting
ShapesPlastics offers state-of-the-art CNC Precision Cutting services. This affordable and accurate technology offers many advantages over other machining methods such as tight tolerances, exceptionally smooth surface finish, scalability, and speed needed for high-volume production.
Through an extensive network of in-house and partner facilities, ShapesPlastics can provide CNC routing services. The process considers material-specific profiles and uses precision camera-guided routing to cut the material with superior edge quality, accuracy, and consistency without accumulating waste and extended lead times.
Plastic Edge Finishing and Polishing
After plastic sheets are cut-to-size, rough saw cut edges might be finished to a smooth edge in several ways, including diamond polishing or flame polishing. The amount of finishing required is dependent on the selection of the polishing compounds on the machined edge; different materials will require different techniques to produce a smooth, transparent edge that will not craze up. This is highly recommended for both individuals such as do-it-yourselfers and commercial clients as it minimizes time spent and costs learning and machining materials.
Diamond polishing adds a shiny luster to the edges and goes together with a buffing process. The buffing process is completed after the polishing is completed to give the edges a higher quality, polished finish.
Since materials such as acrylic sheets are stress-sensitive, the process of flame polishing requires great operational skills to avoid breaking or cracking the plastic sheet. When done properly, flame polishing produces the clearest finish in the most time-saving manner.
For smaller orders, drill press services are available to form holes in a variety of materials in the most accurate way. The precision means that it will drill at precise angles (usually ninety degrees) and it will drill holes of identical size, depth, and position. For larger runs, routing services are recommended.
Rounded Edge vs Radius Corner
Radius corner means the corners of the sheet are rounded giving the sheet smoother, more arch-like corners. These are commonly done for applications that are exposed to traffic areas or where people walk to avoid sharp and pointy edges that can be prone to accidents. The standard radius corner offered here at ShapesPlastics are ½” - ¾”. Rounded edge is when the top and bottom surface of the plastic sheet is rounded, also described as “round over”. This is commonly used for desks and countertops.
