AbstractThe integrated metal/plastic injection moulding enables the production of plastics components with integrated conductor tracks and contacted inserts using an injection moulding machine. For this purpose, first a plastics carrier, which contains a groove for the later conductor track, is injection moulded and following electrical inserts are placed along the groove. The conductor track is then die‐casted from metallic solder. By using thermally conductive plastics, heat generated along the conductive paths and at the electrical inserts can be dissipated.

The use of fiber-reinforced-plastics (FRP) contributes to an efficient implementation of lightweight design due to their outstanding specific mechanical properties. The RTM process offers great design freedom and allows the integration of functional elements during manufacturing. Embedded metal elements, so-called inserts, can be used to deal with the load transfer to structural parts. These elements have distinctive characteristics in comparison to other joining technologies. For example, detachable connections can be established with the help of inserts.

Joining is a key enabler for a successful application of thermoplastic composites (TPC) in future multi-material systems. To use joining technologies, such as resistance welding for composite-metal joints, auxiliary joining elements (weld inserts) can be integrated into the composite and used as an interface. The authors pursue the approach of embedding metal weld inserts in TPC during compression moulding without fibre damage. The technology is based on the concept of moulding holes by a pin and simultaneously placing the weld insert in the moulded hole. Subsequently, the composite component

Abstract One method to produce electronic systems with high resilience is the encapsulation of metal inserts, for example, lead frames, using assembly injection molding.

Purpose Polymer rapid tooling (PRT) inserts can be used as injection moulding (IM) cavities for prototyping and low volume production but lack the robustness of metal inserts. Metal inserts can withstand high injection pressure and temperature required, whereas PRT inserts may fail under similar parameters.

This method needs modification, as high injection pressures and temperatures can damage the PRT inserts. There is a need for a metho

Modification of knee joint wear simulation methods has included ‘anatomic attachment’ of unicondylar knee replacements (UKR) onto synthetic femurs with material properties and morphology similar to human femurs. The present study assesses the effect of such modification by comparing the damage patterns on UKR polyethylene inserts after in vitro simulation using standard and modified simulation methods with those on inserts retrieved after in vivo function. Three groups of UKR inserts were evaluated after retrieval (Explant Group, n = 17) or after knee joint wear simulation with the components

The mold-making industry is currently facing several challenges, including new competitors in the market as well as the increasing demand for a low volume of precision moldings. The purpose of this research is to appraise a new formulation of Metal Epoxy Composite (MEC) materials as a mold insert. The fabrication of mold inserts using MEC provided commercial opportunities and an alternative rapid tooling method for injection molding application. It is hypothesized that the addition of filler particles such as brass and copper powders would be able to further increase mold performance such as c

It is known that during the cutting process the tool wears out. This is due to the high temperatures, the relative velocities and shocks between the contact surfaces of the tool-part and the mechanical and thermal stresses which appear on the active surfaces of the tool. The result is loss of cutting and reduced processing quality. This involves taking measures to increase the values of the cutting tools and/or the durability of their cutting inserts. Tool durability can be increased by various coating methods by the depositing in a vacuum of some different materials which achieve the necessar

Abstract Small field-of-view (FOV) cone-beam computed tomography (CBCT), which employs low-cost, small-area flat-panel detectors, is often used in dental CT where only a limited volume of an examined object is reconstructed using the standard filtered-backprojection algorithm. However, when examining with a small FOV, the surrounding structures located outside the FOV exacerbate the inhomogeneity of the inherent distribution of gray values (GVs) in the reconstructed CBCT volume. To address this issue, this study presents an effective method to minimize the inconsistencies in GVs in small FOV C

Thermoplastic composites (TPCs) are predestined for use in lightweight structures, for example, in automotive engineering, due to their good specific mechanical properties. In many areas of lightweight design, the use of metal inserts for load introduction into composite structures has become established. The inserts can be embedded during composite manufacturing without fibre damage. The technology is based on the concept of moulding holes with a pin tool and simultaneously placing the insert in the moulded hole. The embedding process results in a complex material structure in the joining zon

Dry and viscous friction is used as a damper of oscillation energy in the construction of metal-cutting tools. A mathematical model of a two-mass oscillatory scheme of the insert of an assembled milling cutter was developed and studied, one of the masses of which models the clamped part of the insert - a press connection with dry friction, and the other - the cantilever part, which is subject to self-oscillations that are possible in the process of metal cutting. The influence of dry friction in the press joint of the insert on the amplitude of resonant oscillations of the cutter and the part

CVD-coated cemented carbides are widely used for various metal cutting applications. It has been established that the textures of the coating materials especially that of the α-Al2O3 greatly affect the cut performance for some applications. The characterization of the coating texture is thus very important. In this paper, inverse pole figures of α-Al2O3 based on XRD with Bragg Brentano geometry were calculated for several metal cutting inserts available in the market. This method is simple, less time-consuming and can be applied to previously collected data and is compared with that of the EBS

The influence of inserts with various configurations on permeate flux through a tubular ceramic microfiltration membrane was studied. The commercial metal-working oil emulsion was used in the experiments. A more extensive study of the effect of shear rate on permeate flux was made by comparing the steady-state flux of the empty tube system and the system with inserts. The cross-flow microfiltration with inserts was found to be simple and effective. Analysing experimental results, it was concluded that the introduction of inserts, irrespective of their configurations, resulted in a significant

This paper will discuss about the next generation insert with cooling feature coupled with forced coolant in machining Inconel 718. The geometry of the insert was changed in a way which has enlarged the surface area approximately 12% compared to regular insert named as nusselt insert. The idea applied in “nusselt insert” was the relation of increase in surface area to heat dissipation. Forced coolant application has become a way to improve existing metal cutt

Over the past decade, the focus of the metal cutting industry has been on the improvement of tool life for achieving higher productivity and better finish. Researchers are attempting to reduce tool failure in several ways such as modified coating characteristics of a cutting tool, conventional coolant, cryogenic coolant, and cryogenic treated insert. In this study, a single layer coating was made on cutting carbide inserts with newly determined thickness. Coating thickness, presence of coating materials, and coated insert hardness were observed. This investigation also dealt with the effect of
