Case Studies

Real production problems, the Soremag analysis and the results obtained on rubber and polyurethane rollers and wheels, and on molded polyurethane parts.

Our case studies

Each case starts from a real plant problem, sets out our wear analysis and presents the solution chosen and its results.

Pâtes & papiers · 1995

Polyurethane wheels instead of a rail rebuild

Rail wear was leading to a rebuild project estimated at between $750,000 and $1.2M — a lot of money in 1995. A wheel covered with a polyurethane developed in the field — Cerathane — stopped the rail wear and lasted 8 years.

Transformation du bois

Wood processing — pressure wheel

A rubber cover that was cracking and cutting, replaced with a tougher 80A polyurethane.

SoreDrain PU 80/90 — outdoor durability

Chutes and catch basins exposed to UV, water and salt: the proof from 10-year tropical climate aging tests and 20-year immersion tests.

Acier & métaux en feuilles

Steel sheet wringing — wringer rollers

Non-driven rollers that were slipping and developing flat spots within weeks. A nitrile reformulated to 60 Shore A instead of 80: no more flat spots, better wringing and ×4 the service life.

Emballage & film

Plastic film — nip roller

Cuts in the rubber that were opening up and marking the film, solved with PolySorNip — a 60 Shore A polyurethane formulation that closes back up and lasts longer.

Textiles & non-tissés

Textile dyeing — padder press roller

Hardness on spec, diameter on spec, no cracks — and the fabric was coming out darker in the center. The roller was deflecting under load: a parabolic crown restored uniform pressure.

Emballage, film & extrusion

Imported film roller — service life doubled

A part bought from the European machine builder, worn at the film edges. Core refurbished, material matched to the wear mode and crown profile revised: service life doubled.
