Abstract Micro-nano fibrillated cellulose (MNFC) films have the potential for applications in, e.g., packaging and printed electronics. However, production paradigm these types of products has still not been established. This study uses twin-rollers to form from high consistency (15% w/w) micro furnishes. MFC furnishes were produced at 20% wt dry matter content with enzymatic hydrolysis PFI ref...

Hemming is a three-step sheet-folding process utilized in the production of automotive closures. It has a critical impact on the performance and perceived quality of assembled vehicles. Using a two-dimensional finite element model, this paper presents a design-of-experiments (DOE) study of the relationships between important hemming process parameters and hem quality for aluminium alloy AA 6111...

High hardening of the steel, which is caused by martensitic transformation through cold forming, leads to significant local elastic roll deformation (flattening). The rolling strain-hardened steel requires higher forces and torques, result in high force. Roll flattening can be reduced using rolls made a material with significantly modulus elasticity. suitability ceramic materials for modern hot...

We report on the manufacture of a first batch of approximately 2,000 Gas Electron Multipliers (GEMs) using 3M’s fully automated roll to roll flexible circuit production line. This process allows low-cost, reproducible fabrication of a high volume of GEMs of dimensions up to 30×30 cm. First tests indicate that the resulting GEMs have optimal properties as radiation detectors. Production techniqu...
