• To consistently exceed customer expectations, quality control and assurance is achieved through:

      •  ● Comprehensive written procedures and policies
      •  ● Extensive electronic records of orders, customer communications and inspection results
      •  ● Detailed records of incoming raw materials
      •  ● Analysis of root cause of non-conformances
      •  ● Corrective actions to prevent recurrence of non-conformances
      •  ● Multi-level incoming order review
      •  ● Comprehensive software expert system advising customers of manufacturability issues
      •  ● Periodic calibration and labeling of inspection tools
      •  ● Designated areas for non-conforming parts
      •  ● Staff members being strongly encouraged to suggest improvements in methods, materials, and suppliers
      •  ● Daily backup of electronic records stored in multiple locations

Advanced Inspection Equipment In-House


Bruker Alpha II FTIR Infrared Spectrometer

With this tester, infrared radiation is used over a broad spectral band to verify plastic samples with a degree of accuracy higher than 97%. Very few other suppliers go to such lengths to ensure that our material is completely in conformance with your specifications.


Optical Emission Spectrometer (OES)

A testing apparatus that uses a current to electrically charge a sample of the material. The resulting discharge of plasma is unique for each element and this pattern can be read by the optical spectrometer to determine the metal’s complete composition.

There are many similar alloys and grades of metal available on the market, and some of them are mislabeled or fraudulent. We offer Positive Material Identification (PMI) for all incoming materials so you have complete confidence that you receive exactly what you ordered. We are one of the few services in China to offer this level of testing.

XRF Analyzer and XRF Spectrometer


X-Ray fluorescence (XRF) analysis is a non-destructive testing (NDT) process by which materials such as metals, plastics, ceramics, etc. are exposed to low level, short-wave X-rays or gamma radiation. Each element reflects the emission with a different wavelength and a specially calibrated spectrometer can analyze the wavelengths to detect what elements are present and in what relative concentrations. The XRF analyzer can also detect banned materials under the REACH and RoHS legislation.


Zeiss Comet L3D 2 Optical Scanner


The Zeiss Comet L3D 2 optical scanner is a portable, state-of-the-art scanning system for capturing and computing 3D data quickly and with a high degree of precision. With easy to use software and interchangeable lenses and sensors, the Zeiss Comet can scan up to five million data points on parts of almost any size within its wide focal range. This is ideal for checking parts for conformity, identifying manufacturing errors and reverse engineering. Just part of our commitment to total quality control.

SmartScope ZIP Lite 300


The SmartScope ZIP Lite 300 is a non-contact optical measuring system using a high intensity white LED light for fast and accurate 2D measurements of parts. High-precision mechanical bearings and DC stepper motors, mounted to a solid granite base, ensure reliable and repeatable precision. Coupled with sophisticated but easy-to-use Measure Mind software, the SmartScope can be quickly programmed to run automated measurements of multiple similar shapes.

 Coordinate Measuring Machine

At its most basic a coordinate is a point, a fixed singular location in three-dimensional space. A series of points can be used to define the parameters of a complex shape. Therefore a coordinate measuring machine (CMM) is any device that is able to collect this set of points for a given object and to do so with an acceptable degree of accuracy and repeatability.




Our Mitutoyo Surfometer measures the surface roughness of an item, so we can ensure a specific surface finish is achieved.



Visual Quality Standards

At junying, we have implemented a Visual Quality Standard for our finishing services to inspect painted finishes and ensure the consistency of cosmetic appearance. We also have a Visual Quality Standard for our plastic injection molding services. This ensures we have a consistent method for inspecting parts. Ensure the surface consistency of different batches of parts.



ISO Certified

We are proud to be fully certified. This demonstrates our commitment to continuous quality improvement, respect for our workers and for the environment.
