Material selection: according to the design requirements and the use of parts, choose the appropriate acrylic material. There are many types of acrylic materials, including transparent, translucent, colored and other types, which need to be selected according to the actual needs.
Material Purchase: Purchase selected acrylic sheets or profiles from reliable suppliers to ensure that the quality of the material meets the standards.
● CNC Programming and Processing Preparation
CNC Programming: Convert the design drawings into program codes that can be recognized by the CNC machine. The programming process needs to consider the tool path, cutting speed, feed and other parameters to ensure machining accuracy and efficiency.
Preparation for machining: Prepare the tools, fixtures and other auxiliary tools required by the CNC machine tool, and debug and warm up the machine tool to ensure that the machining process is carried out smoothly.
● CNC machining
Cutting: Use the CNC cutting machine to cut the acrylic sheet accurately and form the basic shape of the part.
Engraving and punching: According to the design requirements, use the CNC engraving machine to engrave and punch the parts. Engraving creates complex patterns and textures, while punching is used to mount or connect other parts.
Hot Bending and Molding: Parts that need to be bent or molded are processed using a hot bending machine. By controlling the temperature and pressure, the acrylic sheet is formed into the desired curved shape during the hot bending process.
● Post-processing and inspection
Polishing and sanding: The processed parts are polished and sanded to eliminate surface burrs and unevenness and to improve the finish and aesthetics of the parts.
Quality Inspection: Conduct comprehensive quality inspection on the finished parts, including size, shape, color, transparency, surface quality and other aspects. Ensure that the parts meet the design requirements and customer expectations.
● Packaging and shipment
Packing: Properly pack the inspected parts to prevent them from being damaged during transportation. Packing materials should be selected to prevent shock, moisture and scratches.
Shipment: Ship the packaged parts to customers according to the time and method agreed in the contract. At the same time provide necessary transportation documents and after-sales service information.
