ATSPL offers quality related services like testing, evaluations, inspection and validation by using in-house as well as outsourced resources.
ATSPL has NABL accredited laboratory in the discipline of Mechanical Testing of Polymers with NABL Certificate Number: T-4131.
Apart from the NABL accredited tests the ATSPL laboratory can also perform specialized testing and characterization owing to the in-house knowledge and expertise in the field of Science and Engineering.
Polymer based materials are developed on the basis of the performance requirements of the part as well as the processing requirements of the part. Suitable polymer material can be suggested and the specifications of the materials can be suggested on the basis of performance requirements. On agreement of proposed specifications, material can be prepared and sample materials can be provided for testing. Pilot production material along with processing guidelines can be made available for production trials and monitoring of the processing trials cam be done by RTC executives is mutually agreed.
Materials are also developed on the basis of desired specifications.
RTC is capable of developing coloured material in a very short span of time on the basis of a component / standard colour plaque or RAL number.
With a written agreement of usage of material, RTC can get the .udb file generated for carrying out Mold Flow Analysis helpful for mould design as well as for setting processing parameters.
2. Testing & Characterization of Polymeric Materials
Various testing and characterization of polymeric material possible is as below:
A. Polymer Identification: Identification of polymer / polymers used in a component or material granules by physical and chemical testing and instrumental characterization.
B. Physical Testing: Specific Gravity, hardness etc.
C.Mechanical testing: Tensile, flexural and impact properties in temperature range -30o C to 150o C of ASTM and ISO specimen moulded as per the guidelines in these standards. The testing can be done for the specimen provided by the customers or by moulding the specimen as per relevant standards of the material sample provided by the customer.
D.Thermal Properties: Heat Distortion temperature, Vicat softening point, Ash content.
E. Burning Behaviour: UL flammability rating as per HB, V2, V0 etc. (Development testing in-house, certification testing – outsourced.)
Flow Properties: MFI, spiral flow in comparison with a material with known flow characteristics for injection moulding.
Shrinkage characteristics – Shrinkage in MD and TD as per ASTM and ISO standards.
Fusion and Crystallization Behaviour – DSC scans with and without interpretation as per customer requirements
Molecular Fingerprints - FTIR scans with and without interpretation as per customer requirements.
3. Components: Inspection, Evaluation and Testing-
For approval of parts by Auto and other OEMs a number of requirements have to be fulfilled. RTC will help of define and propose the requirements if necessary and will support to fulfill the defined / agreed requirements.
Dimension report and fitment checks:
Dimension reports can be generated on the basis of KPSs defined or with respect to the drawings or CAD files
Checking fixtures and can be designed and fabricated and the fitment check can be done with the help of checking fixtures
Part thickness measurement at desired locations can be done with the help of a profile projector.
Part level mechanical tests:
Specimen can be prepared by cutting from the moulded parts as specified on the drawings / specs
Tensile, flexural, impact and HDT testing can be carried out on the specimen cut from the part at desired temperatures.
Falling weight impact testing can be carried out at desired locations of the part at desired temperatures.
Part level chemical / oil resistance:
Testing the effect of chemicals, oils, artificial perspiration etc by rubbing on parts specified number of times and measuring gloss & colour before and after.
Part Level Aesthetics:
Testing of scratch resistance by Taber five figure abrasion or Erikson Grid Test
Testing for Mar resistance by Erikson grid test; measuring gloss before and after indentation.
Colour and gloss at designated locations on the part
Environmental cycling test:
Form stability to temperature and/or humidity cycling as per specifications
Observing and monitoring changes on surface
Checking dimensions before and after cycling
Checking fitment before and after cycling.
Heat Ageing test:
Exposing part to specified conditions and observing the part surface for changes.
Measuring changes in properties after exposing to desired conditions.
Volatiles and Fogging:
Testing for fogging and VOC as per the desired specs.
Weathering and changes after weathering:
Colour fastness to artificial light, Exposure in Xenon Arc WeatherOmeter, UV WeatherOmeter
Tackiness development after exposing in oven or WeatherOmeter
Vibrational durability / Fatigue Testing as per specifications
Static and cyclic loading tests.
4. Support to Quality System-
Support to documentation required for PART & Material Approvals - Production Part Approval Process (PPAP)
To ensure quality during regular supplies:
Control plans and quality system are required
Approved method and process of packaging and transportation is required.
Support for making Control Plans, Quality Systems etc.
