The presence of nano and microplastics in water has increasingly become a major
environmental challenge. A key challenge in their detection resides in the relatively …

This Prospective covers an overview of the injection molding process and the importance of
mold design and tooling considerations, important material requirements and thermal …

Residual stresses are created in engineering components during fabrication and
processing. Such stresses can strongly influence structural behavior. They are generally …

Material extrusion is a common additive manufacturing process that subjects polymers to
non-steady deformation and thermal processing to build a customized part. The mechanical …

Plastic lens arrays (PLAs) have the advantages of a light weight and a compact size.
However, their optical performance is often degraded by warpage, caused by the …

Mold flow simulations are performed to determine the processing conditions which optimize
the optical performance and geometry deformation of a plastic Fresnel lens manufactured …

In this paper, we explore a straightforward two-step method to produce high-purity, vertically
aligned multi-walled carbon nanofibres (MWCNFs) via chemical vapor deposition (CVD) …

Injection moulding has been a pivotal technology in the mass production of polymer optics
for many years. The surface quality of the moulding inserts exerts a significant influence on …

This study utilizes the mold flow analysis technique of the injection compression molding
(ICM) process, combined with the Taguchi–gray relational analysis (GRA), for process …

In precision optical applications, plastics thick-walled optical lenses are increasing.
Dimensional stability and optical performance are the critical issues that should be …
