About CNC Plastic Machining
Features
Precision Manufacturing
Our sango automation CNC machining service can achieve tight tolerances (0.05mm to 0.03mm or higher) and excellent surface finishes (capable of Ra0.8) to meet most customers' demanding applications for dimensional accuracy and appearance.
Wide Material Compatibility
We can process a wide range of plastic materials, such as ABS, polycarbonate (PC), acetal (POM), polyethylene (PE), PEEK, and acrylic (PMMA).
Complex Geometry
Our factory has a variety of machining equipment, such as CNC milling machines, four-axis and five-axis CNC machines, etc., and our CNC milling and turning capabilities can easily cope with complex 3D shapes, cavities, holes, threads, and fine features.
The process of plastic CNC machining
Requirements analysis and design review stage
The production process begins with a deep understanding of customer needs, and engineers review 3D models and 2D drawings based on part application scenarios (e.g., biocompatibility of medical devices, insulation of electronic components), focusing on assessing the unique processing risks of plastics: such as the tendency to deform of thin-walled structures, stress cracking that can be caused by sharp internal corners, and recommend the optimal material based on factors such as mechanical properties, chemical resistance, and cost (e.g., PEEK for aerospace parts, UV-resistant acrylic for transparent shells).
Programming and process planning phase
Based on the approved design, CAM engineers use specialized software to generate toolpaths. In view of the low melting point characteristics of plastics, the layered cutting strategy is forced to be used during programming (such as processing 10mm deep grooves in 4 times), and a compressed air cooling system is designed to replace the traditional cutting fluid. At the same time, large spiral angle diamond-coated tools are selected to reduce frictional heat, and vacuum adsorption fixtures are customized for easily deformed parts to control the processing deformation from the source.
Material pretreatment and clamping stage
Purchased plastic sheets/rods are subject to strict pretreatment: hygroscopic materials (e.g. nylon PA6) must be dehydrated in an oven at 80C for more than 24 hours. The clamping technique is used in step-by-step pressing technology - the blank is fixed with low torque first, the machine is suspended after roughing to recalibrate the clamping force, and a silicone buffer layer is applied to the contact surface to prevent dimensional drift caused by stress release during the finishing stage.
Core processing execution stage
High speed (18,000RPM) + fast feed (2m/min) for roughing and fast cutting allowance with 0.3mm finishing allowance reserved. The finishing phase is particularly critical: the use of a special polishing edge milling cutter, combined with a micron-level cutting depth (0.05-0.1mm) and a cooling air curtain, ensures that the cutting temperature is always lower than the material's glass transition point (e.g. PC material is controlled below 145C), while the high-pressure air gun purges chips in real time to prevent the molten plastic from re-bonding to the workpiece surface.
Real-time quality monitoring stage
During the machining process, online inspection is carried out for each completed key feature: laser displacement sensor is used to monitor the thin wall deformation, the key aperture is measured by a pneumatic gauge, the tolerance is required to 0.05mm mating surface, and the machine tool probe is started to scan the three-dimensional surface to ensure that thermal expansion does not lead to dimensional deviation.
Post-treatment and surface optimization stage
After the parts are offline, they undergo fine processing: microscopic burrs are manually removed with ceramic scrapers, and low-temperature plasma deburring technology is used for deep holes; Differentiated surface treatments are implemented according to functional requirements - the optical lens holder needs to be polished with diamond paste to Ra0.1m, while the friction parts are sandblasted to form an oil storage texture, and the acrylic edges are polished with hydrogen flame to achieve an optical transparency effect.
Final inspection and protective packaging stage
Perform full-scale verification on a coordinate measuring machine (CMM) and issue a test report with the batch number of the material. The packaging stage is strictly operated according to the material characteristics: static sensitive parts (such as semiconductor carriers) are vacuum-encapsulated with anti-static film, porous materials (such as UHMW-PE) are added with desiccant to prevent moisture absorption and deformation, and finally the honeycomb structure EPE foam is used to customize the transport tray to ensure the delivery of precision parts without damage.
