China Polycarbonate (PC) CNC Machined Parts Factory
Overview
XCM CNC is a Shenzhen Polycarbonate (PC) CNC machining factory organizing repeat supply of transparent guards, large windows, and equipment panels through material-lot management, matched equipment capacity, and batch consistency. It is certified to ISO 9001 and IATF 16949 and uses Matsuura MX-520, Brother machining centers, and related equipment. MOQ is one piece and standard lead time is 10-15 days. Engineering assesses stress-cracking risk, annealing, and protective packaging before sample approval and repeat-order scheduling.

Polycarbonate (PC) Large-Format Equipment Capacity for Factory Supply
Factory supply can match large guards and transparent panels to 3000 x 1600 x 1400 mm milling travel and Dia. 1250 x 2000 mm turning capacity. For structures with M2-M220 threaded mounting holes and +/-0.03 mm regular dimensions, scheduling confirms machine loading and whether the 10-15 day delivery cadence needs split batches. Large-part fixturing direction and annealing are set on the first order and reused for repeat orders.
Polycarbonate (PC) Material-Lot Tracking for Repeat Orders
Repeat PC orders can link material lot, sheet source, and inspection record to every shipped batch, protecting material consistency across deliveries. When a structure includes precision mating holes or 0.015 mm position, first-article reinspection, batch changes, and CMM records enter the same delivery process. Samples take 3-7 days and material arrival is confirmed before batch scheduling.
PC Thread and Keyway Machining for Supply Parts
PC structural threads can start at M2 and extend to M220 on large flanges and connectors, with NPT, BSP, G, and PT pipe-thread standards supported. Minimum keyway width is 1.0 mm and selected mating shaft features can use +/-0.005 mm by drawing review. Plastic threading controls feed and pilot-hole size to avoid chipping and damaged threads.
PC Transparent-Part Batch Inspection and Export Protection
Before batch shipment, PC transparent parts are checked by grade for Ra 3.2 um standard faces and Ra 1.6 um precision faces, with selected rotational features rechecked for 0.012 mm coaxiality and 0.01 mm runout. First-batch cosmetic standards, protective-film coverage, and isolation-packaging method are organized into standard work instructions used by later batches.

Applications
Large PC Guards and Safety Window Supply Parts
Typical parts: Safety Viewing Window, Protective Cover, Transparent Guard.
PC impact resistance and transparency suit repeat supply of safety windows, guards, and transparent equipment covers. A 3000 x 1600 x 1400 mm milling envelope covers large panels. Repeat orders follow the first-batch confirmed material lot, annealing parameters, and protective-film specification, reducing re-confirmation time.
Medical Transparent Housings and Viewing Window Batches
Typical parts: Medical Device Housing, Transparent Inspection Window for Diagnostic Equipment, Portable Monitor Bezel.
Impact-resistant transparent PC suits batch supply of medical equipment housings and viewing windows, subject to drawings and industry requirements. ISO 13485 controls can support material certificates and CMM reports; sampling ratio and cosmetic datum are recorded in standard work instructions after first-order confirmation.
LED Transparent Covers and Lighting-Cover Supply Parts
Typical parts: LED Lighting Cover, Clear Lamp Cover, Diffuser Cover.
PC light transmission, flame-retardant grades, and dimensional stability suit batch machining of LED covers and lamp covers. Curved areas use Ra 1.6 um control for optical scattering, mounting holes use 0.015 mm position to align lamp structures, and flame rating is checked from the lot certificate on material receipt.
Transparent Equipment Panels and Impact-Resistant Guards
Typical parts: 5G Base Station Enclosure, Fiber Optic Termination Box Cover, Industrial Camera Protective Lens.
PC impact resistance and dimensional stability suit transparent equipment panels and impact housings. Panel holes and assembly edges are traceable through batch inspection records; before shipment, each part receives transparent-face cosmetic confirmation and isolated packing to reduce transport-scratch risk.
Why Choose Us
Complete Quality System and Equipment Coverage
The factory organizes quality processes around ISO 9001, ISO 13485, IATF 16949, and GJB9001C, using DMG, Mazak, Matsuura, Brother, and other equipment for polycarbonate transparent parts, impact-resistant windows, and large protective guards. Drawing review for PC transparent panels, flame-retardant parts, and medical-device housings can confirm stress control, polishing, and protective packaging together.
Broad Size Coverage
Machining covers needs from small connectors to large structural parts, including PC transparent windows, impact-resistant panels, small covers, larger guards, medical-device housings, and flame-retardant transparent parts. Three-axis travel reaches 3000 x 1600 x 1400 mm and turning diameter reaches 1250 mm; the production plan is confirmed for fixturing, stress-cracking risk, polishing, and transport protection.
Tiered Equipment Strategy for Low-Cost CNC Machining, Quality-Assured Production
XCM CNC uses CNC equipment from mainland China, Taiwan, Japan, and Europe or the United States. Lower-tolerance operations can run on domestic or Taiwan machines, while high-precision work uses imported equipment such as DMG and Mazak. Matching equipment to actual precision requirements reduces machining cost while meeting drawing requirements.
Repeat-Order Scheduling and Batch Management
Repeat PC guard and transparent-panel orders can reuse first-batch material lot, machining parameters, and inspection datums, reducing the cycle for every batch. Scheduling follows equipment capacity and delivery windows: large parts go first to large-travel machines and smaller parts can batch on Brother machining centers. NDA signing is available for drawings and project information.
Export Packaging and Transparent-Face Transport Protection
Cosmetic reinspection, protective-film coverage, isolation pads, and export packaging are standard delivery steps for PC transparent parts. Foam with cartons or wooden crates is selected for DHL, FedEx, UPS, or sea-freight requirements. Large windows and medical housings use dedicated transparent-face supports to reduce scratches and stress concentration in transit.
FAQ
How large can CNC machined Polycarbonate (PC) parts be at your factory?
Large PC parts are assessed against three-axis travel of 3000 x 1600 x 1400 mm and turning capacity of Dia. 1250 x 2000 mm. Final size depends on sheet size, fixturing, transparent-face protection, and stress control. Large parts are prioritized on large-travel equipment, and fixturing direction and annealing are confirmed on the first order.
How do you track material lots for repeat Polycarbonate orders?
After each PC sheet lot arrives, its lot number, supplier certificate, and grade are recorded and linked to inspection records for the specific parts. Repeat orders can keep the first-batch material source; changing supplier or grade requires renewed first-article confirmation and performance comparison.
What happens when switching from prototype to repeat production for PC parts?
After sample approval, machining parameters, fixture plans, annealing conditions, and inspection datums are compiled into standard work instructions. Repeat orders follow those instructions, while the first batch still receives CMM sampling to confirm dimensional consistency. A design change triggers revision control and reassessment of affected operations.
How polished can CNC machined Polycarbonate parts be?
PC transparent parts can use edge polishing and surface-protection processing according to cosmetic-face grade. Precision faces can use Ra 1.6 um and standard milled faces Ra 3.2 um. Final polish result depends on grade, structural thickness, transparent-face location, and sample acceptance standard.
What Polycarbonate parts does your factory usually supply?
Common PC supply projects include large guards, transparent windows, equipment panels, transparent medical housings, and flame-retardant transparent parts. Batch supply confirms material lot, cosmetic datum, polishing method, and packaging protection first; repeat orders follow the first-order standard.
How do you organize inspection and export packing for PC transparent parts?
Cosmetic reinspection, protective film, isolation packing, and export protection are managed as one delivery process. Foam with cartons or wooden crates is selected by part size and shipping requirements, and large transparent faces receive dedicated isolation supports. Protection is confirmed against customer acceptance standards and transport method.
