The physicochemical laboratory introduction

        Wuxi Gissing Acoustic Auto Parts Technology Co,Ltd- Materials Laboratory was established in August 2008. It is a high-tech service supplier which has skilled technology, well service and fine management. It can provide product enviromental test and product reliable test for industrial enterprises, research institutions and other companies. Such as product safety test, chemical analysis, production authentication and other one-stop technical service. Gissing continuously exploring and innovating in the vehicle and component making field. It is dedicating the entire automotive industry chain to automotive OEMs and parts manufacturers, including test and authentication. Thus Gissing has become a high-tech service supplier in  vehicle and component  making field.

  • Analysis of VOC and hazardous substances 
  • Xenon lamp light fastness test 
  • Product environment reliability test 


     In March,2012,the Environment Protection Department and the General Administration of Quality Spervision Department jointly issued the "Guide to Quality Evaluation of Air in Vehicle" GB/T 27630-2011. So far, we have the standards about domestic air quality in vehicles.
        In the book, it limits the potency of volatile organics about benzene, toluene, xylene, ethyl benzene, styrene, formaldehyde, acetaldehyde, acrolein these 8 organics. According to these 8 kinds of restricted substance of national standard, each big car factory has specified and modified the VOC emission standard about vehicles, components and materials, so as to effectively control the vehicle interior air quality to meet the requirements of the national standards.
      Gissing materials laboratory can provide VOC test and technical support to the auto parts and materials companies. It is authorized by many European, American and Japanese vehicle companies

Component test method: big bag / small bag

Compound test:
          1.organic test: benzene, toluene, ethylbenzene, o-xylene, m-xylene, p-xylene, styrene, and hydrocarbon, alkane, acetidin and other kinds of volatile compounds, TVOC, SVOC and other parameters.
          2.ketones test:formaldehyde: formaldehyde, acetaldehyde, acetone, acraldehyde acrolein and other kinds of aldehydes and ketones.

Material test:
        SVOC, TVOC, aldehyde and ketone, total carbon, formaldehyde, atomization, odor, amine distribute


  Xenon lamp aging test integrates optical radiation, temperature, relative humidity, moisture and other aging factors. It simulates the climate environment under the circumstance of using indoor and outdoor light source. At the same time, it combines temperature and humidity with water spraying period. So the test method is used by most international automobile companies to do the artificial light aging acceleration test.

        Environment is an unavoidable and must be considerated factor to products, the statistical data which has been accumulated after several years shows that the product failure rate caused by the environment is up to about 52%. And because of the bad environment, the reliable requirements for auto parts and material is much higher than household products, so the simulation experiments of temperature, humidity, light , radiation, mechanical stress are becoming the indispensable method for quality control in production and research.

 

★our advantages:

In accordance with the requirements of the vehicle company, the environmental test chamber has complete configuration and can be satisfied their standard requirements.

We have more than ten environmental chambers, covering the temperature range of -40℃ to 300℃, humidity range of 25% to 98%, the volume range of 0.4m3 to 45m3, so we can do a lot of tests like storage and working in high and low temperature condition, humidity and temperature cycling and  alternating, component aging, temperature shock and other environmental adaption tests. It can also do screening test and life length test and so on.

The environmental chamber is so large that the vehicle doesn`t need to be cut and it can show the realistic situation of the vehicle.

We have strong technical ability and have been authorized by many vehicle companies.






Two 0.4m³ chambers      Four 1.0m³ chambers                               A 1.8m³ chamber                   A 1.0m³High temperature environmental chamber









Three 12m³ chambers                                        Three 26m³ chamber                                                                               A 45m³ chamber
  • Side curtain airbag explosion test 
  • Material analysis 
  • Material test 
  • Quotation 
  • contact information 
       The laboratory has an area of 185m2 explosion chamber, it is suitable for all the size of sedan car currently on the market in this high-low temperature explosion test chamber. The testing temperature can be controlled from -40℃ to 100℃. The explosion system has two high-speed cameras with 20fps to 20000fps frame range which means they can clearly record the whole process of explosion and do playback also.

   Cutting reinforced body                       Installation and identification                       The explosion before the examination          The explosion of post processing
        In order to better analyze and solve the quality problems detected by vehicle  interior tests, we specially configured with international advanced materials analysis equipments. They can do qualitative and quantitative verification to analyze the composition, structure and thermal stability of automotive interior materials. We can offer the valuable analysis data to customers about product quality improving and process optimizing!
