Complaint processing
We support you with complaints regarding
- Glass products with defects such as glass breakage, vacuum loss, deformation, scuffing (abrasion on glass surface at contact points with other bottles), labeling problems, particles on inner surfaces
- Problems during filling with regard to foamer (irregular filling heights)
- Closure problems such as leakage (line-over finish), torque abrasion, closure abrasion
- Gushing (uncontrollable gushing and foaming of carbonated drinks when opening the bottle)
- Creation and revision of specifications with corresponding AQL values
- Foreign body analyses of e.g. glass splinters, plastic or metal particles
- SEM-EDX analyses according to DIN ISO 22309 for semi-quantitative content determination or general identification of the material, if necessary with image documentation, chemical scan analyses, mappings, line scans (depending on the order)
- ICP-OES analysis according to DIN 51086-2 of the elements or element oxides: Al, As, B, Ba, Bi, Ca, Cd, Ce, Co, Cr, Cu, Er, Fe, Hg, K, Li, Mg, Mn, Mo, Na, Ni, P, Pb, S, Sb, Se, Si, Sn, Sr, Ti, V, Zn, Zr
- X-ray fluorescence analysis (XRF) in accordance with DIN 51001 and DIN 51418 (> 0.001 % by weight concentration) for the analysis of other elements such as F, Cl, Br, N
- FT-IR spectroscopy according to ASTM E 1252 e.g. for plastic analyses, boron
- Density determination using the floating method, sinking method
- Microscopic examination according to ISO 8039
- Melting point determination, e.g. of plastics
Please note that a reference material is generally useful for an unknown find, but of course not necessary. Most of the examinations are carried out in an almost non-destructive manner.
- Fracture origin analysis
- Surface examination with regard to scratch resistance (focus on HEV/KEV coating), labelability, satin finish, printing
- Investigations and measurements of dimensions and bodies, e.g. using a microscope, 3D measurement and computer tomography (CT)
- Corrosion analyses, e.g. of deposits on the inner surfaces of the glass
- Stress assessment, e.g. of cooling or streak stress
- Impact resistance tests (pendulum impact test, impact test)
- Internal and vertical pressure
- Thermal shock resistance
- Sliding angle test
- Color measurement on enameled and printed glass surfaces in the installed state using a spectrophotometer, e.g. to determine the ΔE value
- Examination of color streaks
- Inclusions, blister
- Detection of e.g. corundum, glass ceramics, refractory material
- Melting tests
- Color measurement on enameled and printed glass surfaces in the installed state using a spectrophotometer, e.g. to determine the ΔE value
