Quality Assurance

Quality Assured

Every rubber moulding follows a route from design, APQP / PFMEA to sampling trials, PPAP and full production supply, within our regularly audited quality system. From initial production through to release of product, control plans, quality standards and process instructions are utilised to ensure that the parts are correct. 

Harboro supply full PPAP Level III submissions for all components with a complete dimensional study and capability data where required.

Harboro supply to IATF:16949 requirements but are happy to work with customers to produce data to meet their specific needs.   

With our in house laboratory we can ensure that the material performance of every component is correct combined with the overall quality level.  This ensures you as a customer are sourcing a component that you can rely upon.

Our continued investment in vision camera systems and new technologies has enabled Harboro to maintain a low PPM requirement on critical components.  We actively encourage our customers to  visit to view how we control our production and maintain this low PPM quality figure on a daily basis across so many different rubber mouldings.

Our capabilities

Harboro’s technical bias is emphasised by its well-equipped on-site laboratory, staffed with qualified, experienced chemists and polymer technologists. We have a team of qualified engineers and chemists working on rubber moulded products plus factory production and maintenance engineering support.  In addition to a quality manager there is a full support team to check, calibrate and manage our systems.

Harboro offers extensive knowledge of materials and testing. We can provide customers with detailed reports regarding suitability of the polymer type chosen for the application.

Our investment in technology such as FTIR spectroscopy and TGA (Thermo-gravimetric analysis) equipment (rarely found in other rubber companies), provides the ability to characterise and deconstruct existing materials.

Some of the tests we offer are:

• Hardness to IRHD, Shore A, Shore D

• Quasi-static compression, tensile and shear modulus

• Dynamic and low temperature modulus

• Co-efficient of friction

• Bond testing and analysis

• Tear and abrasion resistance

• Ozone and UV resistance

• Permanent set

• Fluid and chemical resistance (Oils, Fuels, Greases, Gas, Acids, etc)

• Hysteresis and resilience properties

• Fatigue life

• Rubber compound identification and characterisation
