Many precision manufacturing enterprises in Chongqing and the southwest region often face difficulties in part measurement and precision control. Building an in-house 3D coordinate testing laboratory requires high investment in equipment, complicated daily operation and maintenance, and sufficient professional measuring personnel, which is unaffordable for most small and medium-sized manufacturing enterprises.

To meet the professional precision measurement demands of the industry, the 3D coordinate laboratory of Chongqing Wanwei Testing Center has long opened third-party testing services to the public. We specialize in providing 3D dimension testing and geometric tolerance testing for various precision workpieces, delivering professional, stable and traceable precision measurement solutions for manufacturing enterprises.

Equipped with a standardized constant-temperature testing laboratory, our center effectively avoids measurement errors caused by environmental factors such as temperature, humidity and vibration. Supported by high-precision 3D coordinate measuring machines, we can complete micron-level precision testing, solving the pain points of large manual measurement errors, incomplete detection of complex parts and difficult measurement of curved workpieces in traditional testing methods.

Our available testing items cover a full range of professional services: basic dimension testing including length, width, height, aperture, hole position and center distance of conventional workpieces; full-set geometric tolerance testing such as flatness, verticality, parallelism, position degree and coaxiality; 3D scanning measurement, digital model comparison and deviation analysis for precision molds, special-shaped curved parts and non-standard parts. We also provide first-piece inspection, prototype testing, batch sampling quality inspection and workpiece wear re-inspection, offering accurate data support for enterprise process optimization, quality rectification and product acceptance.

Our services widely cover multiple manufacturing industries in Chongqing and southwest China, including precision molds, auto parts, new energy accessories, 3C electronics, hardware machinery and medical devices.

By choosing the 3D coordinate testing services of Chongqing Wanwei Testing Center, enterprises can access professional third-party testing services without high investment in equipment procurement and operation maintenance. All testing procedures are strictly implemented in accordance with industrial measurement standards, and official testing reports can be issued for product delivery acceptance, factory audit, quality traceability and process rectification.

With years of experience in precision testing services, Chongqing Wanwei Testing Center relies on a team of professional engineers, standardized testing procedures and high-precision testing equipment to help manufacturing enterprises in southwest China reduce costs, improve quality, control product accuracy and stabilize product quality.

Enterprises in need of 3D coordinate testing, precision part dimension & tolerance testing and mold 3D testing in Chongqing are welcome to consult and cooperate. We support sample delivery and mailing, and laboratory on-site visits are available by appointment.
