  • .dwg / .dxf：AutoCAD格式，精准识别二维激光切割与钣金展平结构。

供应链工厂资质体系

供需引擎平台撮合的制造厂商涵盖多种国际与国内质量认证体系，包括但不限于：ITAR、ISO 9001:2015、AS9100D、ISO 13485:2016、IATF 16949:2016、CMMC Level 2。

在线钣金核价和CNC核价是如何计算成本的？

系统利用AI特征识别内核自动解析3D图纸。对于CNC加工，能精准提取孔位、开槽、盲槽（有一侧开口的槽位特征）等几何数据来算切削工时；对于钣金加工，则能计算激光切割线长度、折弯次数以及展平面积，结合当前材料行情给出精准的加工成本估算。

免费在线核价后，平台如何帮我匹配制造厂商？

供需引擎会根据零件识别出的独特特征（如含精密滚珠丝杠、深孔加工、复杂模具型腔、超大体积钣金件等）和认证要求，一键无缝匹配给具备相应高匹配度工艺能力的优质制造厂商。

The manufacturing shops and suppliers matched by our engine cover a comprehensive range of domestic and international quality certifications, including ITAR, ISO 9001:2015, AS9100D, ISO 13485:2016, IATF 16949:2016, and CMMC Level 2.

How does the online CNC quote and sheet metal pricing system estimate costs?

The system utilizes an advanced AI feature recognition kernel to analyze 3D CAD files. For CNC machining, it extracts geometric topologies such as holes, slots, and blind slots (slot features with at least one open side) to calculate tool paths and machining cycle time. For sheet metal fabrication, it evaluates laser cutting linear lengths, bending counts, and flat pattern areas to deliver highly accurate manufacturing cost estimations aligned with current material market rates.

How does the platform match me with the right manufacturer after a free online quote?

Our proprietary large model algorithm base identifies the unique processing attributes of your parts—such as precision ball screws, deep hole drilling, complex injection mold cavities, or oversized sheet metal enclosures. It then matches your RFQ with verified manufacturers who possess the precise machinery, capacity, and quality standards required for your order.
